COMBINED SEWER OVERFLOW IMPROVEMENT STRATEGY

SOUTH WEST AREA REPORT

INTRODUCTION

Storm water overflows on sewerage systems are designed to reduce the capacity of combined or partially separated systems which would otherwise be required to carry excessive volumes of rainfall generated storm water. They act as release valves when the maximum sewerage capacity is reached during peak flow events and thus prevent flooding and damage to the sewerage system. The majority of Welsh' sewerage systems * receive both surface water and sewage (as well as trade effluent in many cases), and storm overflows are therefore;described as Combined Sewer Overflows or CSOs. In theory CSOs • are designed to minimise the impact on the receiving watercourse by only discharging diluted sewage into rivers when their assimilative capacity has also been increased by a rainfall event. In practice these ideal criteria are not always met and grossly aesthetically polluting discharges do occur.

There are believed to be between 2,500 sand 3^,000 ;CSOs i.n the Welsh Region of the NRA. Prior to this strategy there was some evidence that a significant number of these discharges were having measurable detrimental environmental impacts on receiving waters (NRA Welsh Region Report Nos „ PL/EAE/91/2 and PL/EAE/91/4) . These ranged from causing fish mortalities to aesthetic problems .due to deposition of sewage derived litter (NRA Welsh Region Report No. PL/EAE/89/2) .

It is • clearly therefore in the interests of both the NRA and Dwr Cymru Welsh Water (DCWW), who own and operate these discharges, that capital investment in CSO improvements is targetted to achieve maximum environmental improvement as well as meeting operational demands .and engineering requirements. It was for these reasons that the NRA commissioned the CSO Improvement Strategy in 1991.

The objectives of this strategy are

to identify and locate all CSOs in the Welsh Region;

to assess their • environmental impact using consistent., standardised techniques.

to produce an objective ranking of their environmental impact*, from which a prioritised list of CSOs requiring remedial vorV: could be developed.. . ---- - 1.5 The CSO Strategy will feed into the NRA's negotiations with DCWW on the investment programme which will identify capital expenditure requirements for CSO improvements and other capital projects over the next 20 years (Asset Management Plan 2 or AMP2) . Such a strategic approach is consistent with that being developed for Sewage Treatment Works (STWs) effluents and the need for CSO improvements will be balanced against the priorities for STW improvements and compliance with EC Directives, in particular the EC Urban Water Treatment (UUWT) Directive which will require significant capital investment.

1.6 The CSO Strategy has been developed in close association with DCWV and their Local Authority Sewerage Agents who have contributed in particular to the identification and location of CSOs. In parallel with this NRA strategy DCWW are also producing an engineering assessment of the requirements for remedial work to improve each CSO identified as a priority by .the strategy.

1.7 In addition to, and in advance of the completion of this CSO Strategy, the NRA/WSA AMP2 Guidelines were produced. These Guidelines describe how planning and implementing the AMP2 process ' should proceed and identify a number of criteria for the assessment of CSOs on sewerage networks serving particular population equivalents, as defined in the EC UWWT Directive. All those CSOs failing to meet these criteria are deemed to be unsatisfactory and will require improvements to make them satisfactory, over a phased period. These requirements, when finalised, will take priority over other strategic needs, but do not negate' the need to complete the Regional CSO Strategy which covers all CSOs, irrespective of population equivalent served. Indeed, the data collected for this strategy was used in carrying out the prioritisation of CSOs for inclusion within AMP2, which would have been impossible without it. The outputs from the two intiatives are therefore compatible and not mutually exclusive.

1.8 Description of the South West Area

The South West Area of the Welsh Region of the National Rivers Authority is approximately 7675 km in size. The area is characterised by three major land use types; intensive agriculture in the West, extensive sheep farming in the North, and a heavily industrialised zone in the South-East. The consequent concentration of population in these areas has implications for the management of sewerage and the treatment of its product.

The south-east of the Area is extensively urbanised and has been so since the beginning of the industrial revolution. The sewerap/: system is therefore mainly of the trunk sewer type, some of which dates back to the end of the nineteenth century, running down to large Sewage Treatment Works (STWs). The majority of CSOs in thi:. area are normally associated with the trunk sewers and discharj'/ from these to a watercourse. In the more sparsely populated.areas to the north and west sewage is treated at much smaller and more numerous STWs. These are supplied by a sewerage network controlled by a large number of Pumping Stations (PSs) . In these areas most CSOs are therefore “ associated with emergency1 overflows at PSs and STWs. There are large seasonal population fluctuations in the western part of the area caused by the popularity of tourism here. This can have serious effects on the propensity of CSOs to discharge in the summer from pumping stations and sewers as the baseflow is likely to be greater in volume.

Given the extent of coastline surrounding the South West Area (approximately 651 km) a large number of CSOs discharge directly to sea. This input has been identified as a major contributing factor limiting bathing water quality at a number of beaches in the area.

The approximate split between Tidal and Inland CSOs within the South West Area is illustrated in the following Table 1.

2. M E T H O D O L O G Y

2.1 The CSO Strategy has been developed in three phases:

Phase 1 - Identification and location of all CSOs using /i variety of information sources.

Phase 2 - Development of criteria for assessing environmental impact and collection of data oi. individual CSO impacts, including site visit.':, collation of existing 'information etc.

3 Phase 3 - Collation and analysis of data to produce Area and Regional based rankings of CSO impacts from which strategic priorities for improvements have been derived.

2.2 Phase 1.

Several existing databases and pieces of work were identified as suitable starting points for phase 1, namely:

i) NRA Consents Register

ii) Welsh Water Northern Division - SSO Improvement Strategy (September 1987)„

iii)NRA SE Division - SSO Improvement Priority Listing (1990).

iv) Welsh Water SW Division. - Assessment of Swansea Sewerage S S O s .

v) Welsh Water List of Existing 2,000 Overflows.

2.2.1 A list of consented overflows was generated from the NRA consents register, which contained information on the location of the overflows (such as name, National Grid Reference (NGR) , receiving watercourse etc*) and formed the basis of the database against which other available information was checked. Using information on overflows from all sources, spreadsheets were set up on Supercalc 5.1 and overflows were grouped according to river catchment. 1:10,000 scale Ordnance Survey maps were marked with the location of all overflows in preparation for site visits.

2.3 Phase 2.

Based on this information site visits were made to each NGR location. NGRs provided often referred to overflow chambers and not dischairge points and a considerable effort was required in some cases to locate the actual discharge point for assessment. If the CSO was not located, then enquiries were made with NRA Pollution Control staff, DCWW and/or their sewerage agents to assist in locating all the overflows. It proved impossible to locate a number of overflows in each area and it was concluded in most cases that the overflows did not exist despite being on the consents register. In other cases, .insufficient information was available from any source to locate the outfalls and a degree of duplication of consents was discovered.

2.3.1 An environmental impact assessment of all the CSOs which could be located was completed using the field data sheet given in' Appendix 6.1. Additional information for use in the prioritisation was collected from Pollution Control staff and is described in Appendix 6 .2 .

2 .4 Phase 3. Environmental impact severity indices have been developed for inland and tidal water CSOs based on a limited number of criteria described briefly below and in more detail in Appendix 6.3. The criteria for prioritising the CSOs on the basis of their impact were limited to those which were consistently available and well validated. The reliability of the inland waters index was assessed against more detailed environmental impact assessments, which included biological data, on a limited number of CSOs in the Ogmore and Rhymney catchments.

2.4.1 Severity Indices for Inland and Tidal Water CSOs

A severity index for each type of CSO has been derived as follows. The main impact criteria for each CSO were categorised as A , B, or C indicating most significant to least. These were then translated to X, Y or Z, as shown below, in order to rank the CSOs in priority order based on their relative environmental impact.

The final index consists of a string of letters (eg. XXYZZ). Before sorting on this index, the CSOs are grouped according to the number of X scores within their indices, irrespective of the relative positions of the X scores.

The five criteria are . listed in order of their importance as indicators of environmental impact, see below. For each criterion in turn there is either a two (dichotomous), or three (trichotomous) choice (A/B or A/B/C translating to X/Z or X/Y/Z respectively) .

The order, of. the X scores on the basis of the criteria 1 to 5 (indicating mo$t significant to least) then determines the ranking of each CSO, within each group. CSOs of equal impact are grouped together.

2.412 Criteria- for Inland Waters CSOs Impact Assessment and Ranking (in descending order of importance)

1. Aesthetic Impact : either any category (except public complaints) scoring 2. or any 3 categories (except public complaints) scoring 1 . or biological impact due to a discharge or group of interconnected discharges.

either any 2 categories (except public complaints) scoring. 1 . or sewage fungus scoring 1. or public complaints scoring

5 C — any ocher than A or B.

Aesthetic Impact was ranked, considering an impact of A or B to be equal. This was achieved by assigning new scores:

A or B - X c = z

2. Dry Weather Operation : A ■= Sewage Discharged B - Clear Infiltrate Discharged C - No discharge

Dry Weather Operation was ranked, considering an impact of B or C to be equal. This was achieved by assigning new scores:

A - X B o r C = Z

3. Toxic or Trade Effluent : A - Yes Component in Sewage ? B - No

Toxic Trade Effluent was ranked by considering it's presence in conjunction with Dry Weather operation, and assigning new scores:

A with sewage discharged during dry weather - X A without sewage discharged during dry weather - Y B with or without sewage discharged during dry weather = Z

4. Impact on LTRQO : A - Yes, class reduced by CSO B - No impact

To be consistent with other ranking scores, new ones assigned:

A - X B - Z

5. Impact on Defined Uses?: A - Yes B - No

To be consistent with other ranking scores, new ones assigned:

A *= X B - Z

2.4.3 Criteria for Tidal CSOs Ranking

1. Aesthetic Impact: A - either : litter present linked to C S O . or : dry weather operation. B - -No aesthetic impact

Ranking scores assigned: A - X B = Z

6 2. Location Relative to A — Above MHWS H/L Water Marks. B — Between MHWS and MLWS C - Below MLWS

Ranking scores assigned: A or B — X C — Z

(Those with an impact of X are split back into A or B for ranking, once the groups of numbers of X's have been determined)

3. Receiving Water Uses : A — Designated Bathing Water B — Other Water Contact Sport (including non*designated bathing) C -= No uses .

Ranking scores assigned: A or B - X C - 2

4. Compliance with Bathing : A *= Fails Water Standard? B — Passes or no information

Ranking scores assigned: A - X B - Z

5., Toxic or Trade Effluent : A ■= Yes B - No

Ranking scores assigned: A - X B - Z

2 . 5 Quality Audit

To ensure accuracy and consistency of the CSO impact assessment (see 2.3.1), an APCO and Appraisal Officer from each area visited 6 local CSOs which had previously been located and assessed by the CSO survey team and in turn completed a field assessment sheet. These data'were compared with those obtained by the CSO survey teams so as to highlight any discrepancies in methodology. The audit also provided data for more than one occasion which were used for a limited assessment of temporal, changes in CSO impacts.

2 .6 Biological Assessment

Mixed results were obtained from the trial application of biological assessment techniques to CSOs in the Rhymney and Ogmore catchments. The industrialised valley rivers tend to have clusters of overflows and in such circumstances it proved impossible to distinguish tho effects of individual discharges. In some rivers other sources of pollution, such as minewaters and old spoil tips impacted or. biological quality and masked the effects of the CSOs. Also, lury/: centres of population high up in the catchments with old s e v e r uy/: systems, ineffective CSOs and urban run-off, impact on the rive.r.'. nearly at source. As a result, the pollution sensitive indicator taxa tended to be missing from some of these rivers and the biological impacts of the CSOs were not evident. However, despite these problems, where there was a 40% decrease in BMWP score which was not due to other sources of pollution, and there was strong evidence, that the impact was due to an individual or cluster of overflows, biological criteria have been included in the ranking c r i t e r i a .

The results of the biological assessments in the Rhymney and Ogmore catchments led to the decision not to continue with biological assessments on a Regional scale. Biological data is therefore only available for a limited number of sites.

3. R E S U L T S

3.1 The original dataset obtained from, the consents database for the South West Area contained details of 850 CSOs. Discussions with DCWW revealed the existence of a further 78 unconsented CSOs giving a total of 928. The results of the survey followed by further dicussions with DCWW and local authority agency staff indicated that 123 of the total were either duplicated consents, or did not exist. Also, the locations of 12 outfalls were unknown to .DCWW and their agents and they were not found during the survey. Thus a total of . 793 CSOs actually exist in the South West Area.

3. 2 The full ranked lists for all inland and tidal CSOs in the South West Area are given in Tables 2 and 3 respectively. These tables include all the original CSOs listed as well as those found during the survey, and will therefore need to be, updated in future to remove duplicate consents, and revocations. Although there are no absolute index values at which an environmental impact is or is not acceptable, the severity index has been split into three categories of impact for inland CSOs as shown in Table 4 below. The first two categories for inland and tidal discharges describe degrees of significant or minor impact whilst the third is described as "no significant impact". The first category in each case includes CSOs which are "unsatisfactory”, according to the criteria in the AMP2 Guidelines, are having a significant impact and which therefore have the highest priority for remedial action. (See Appendix 6.4 for further information on definitions of Unsatisfactory and Satisfactory CSOs) . The number of inland and tidal CSOs in each category is summarised in Table 4.

I sc; Description of categories (inland and tidal):

Unsatisfactory (highly significant impact) = Category 1 Moderately Unsatisfactory (minor impact) _ = Category 2 Satisfactory (minimal or no significant impact) = Category 3.

3.3" Those discharges falling into the Not Ranked category are listed in Table 5 and include CSOs which were present on the consents database but which could not be located by the survey teams.

3.4 Problem Areas in the South West

The results of the severity index ranking show that 39% of the inland CSOs were in the highest Category 1. These are clearly the CSOs which should be afforded the highest priority for capital investment and the systems on which these high priority problems occur are highlighted below.

3.4.1 There are at least four problem overflows in the Llanharan area within the Ewenny catchment. These are mainly due to the number of public complaints and the presence of toxic or trade effluents within the CSOs.- The system, is a trunk sewer and gravitates to Pen-y-bont STW.

3.4.2 The Garv catchment encompases an old industrial area and the capacity of the ' trunk sewer to carry waste has always been considered suspect. However, the strategy has identified very feu- problem overflows. Pont-y-cymmer is the worst and there is ,i toxic/trade problem from the Rexel works at Llangeinor. The fact that there are no heavily impacting overflows in this valley i probably due to depopulation from the area and little new housinr. being built.

9 3.4.3 The main problem within the Llynfi catchment appears Co be the antiquated state of the sewerage system. There appears to be little effort to maintain the CSOs in a good, effective working order. CSOs with the most serious . major problems are located in the area upstream from Maesteg. Specific problems occur in Caerau Square and the toxic/trade content of discharges throughout much of the catchment also pose problems.

3.4.4 As with all sewerage systems within the SW Area the biggest problems in the Ogmore catchment seem to lie in the areas with the greatest density of population. There is a corridor of population which runs from Ogmore Vale to Blackraill and on to Bridgend. The greatest problems occur on the Ogwr Favrr part of the river around Blackmill/Ynyslas where the trunk sewer from the Ogwr Fach joins the main trunk sewer. The Aberkenfig area also has problem CSOs where the Llynfi system joins the main trunk sewer. Bridgend itself has problems around, the Nant Cefn Glas where the sewer appears to be overloaded due to the housing estates. The system seems to be able to cope from this point down as far as the main STW at Pen-y-bont.

3.4.5 The only problem CSO in the Kenfig catchment is the Pumping Station Marlas which receives many public complaints

3.4.6 The upper part of the Afan catchment contains, an old sewerage system along with the new system. There are therefore a number of disused overflows in this area. Further down the catchment towards Cwmafan there are a number of poor CSOs. This impact is probably due to the development of new housing. At Port Talbot there are fewer problems but there are CSOs which discharge regularly to the Afan Estuary.

3.4.7 Within the Neath catchment there are many disused. CSOs around Aberdulais. This is due to the development of a new trunk main. The main problems are in the Glyn-Neath area, of the trunk sewer where there is a major litter impact on the river. A number of Neath CSOs, Llaritwit Church CSO and The Gunsights CSO are in a poor state of repair. The CSO in Bryncoch at Llydhirhaul on the Clydach is also a problem.

3.4.8 The Tawe catchment has a few poor CSOs in the Ystradgynlais/Gurnos area, but the main problems start from Pontardawe downstream with impacts from Trebanos STW and the industrial estate in Pontardawe. There are problems in Llansamlet with culverted CSOs to the Nant-y-fendrod, and at Ynysf organ bridge a large CSO appears to discharge virtually full-time. All the CSOs from this point downwards appear to be overloaded, in particular the discharges from Morriston and area to the Burlais Brook. In the dock area of Swansea there are a large number of CSOs which discharge be Low tho level of the impoundment which made them very difficult to assess. However, the presence of CSOs within the barrage impoundment must tic considered a problem to the water quality.

These are spread through the entire catchment with the river Dafen, Gvilli, Llan, Mwrg, and- Loughor having the greatest concentration of high impact CSO’s.

4.10 About half the CSOs discharging into the Gvendraeth catchment also have a highly significant inpact. These are spread throughout the catchment with two small concentrations of. high impact CSOs in the' Drefach and Pontyberem areas.

4.11 The greatest concentration of highly significant CSOs within the Cleddau catchment are based around the population centre of Haverfordwest. These discharge to Merlin's brook, Slade brook, St. Martin's stream and the Western Cleddau.

4.12.In the remainder of the catchments, individual CSOs tend to be the problem rather than groups of overflows. These will therefore neec to be considered on an individual basis for investment rather thar. being grouped into schemes.

4.13 The highest impact area for tidal CSO problems is the Loughor Estuary. In the SW area only 17 tidal CSOs out of 109 had a high impact. New schemes for Swansea Bay, the Neath Estuary and Loughor are being considered and should improve the water quality of the Loughor Estuary and Swansea Bay. The other tidal areas should be considered on an individual basis.

DISCUSSION

A number of difficulties arose during collection of impact data and development of this strategy. These were due to a number of factors which included inconsistencies between the NRA's Consent Register and DCWW's asset database.

The main problem involved location of the CSOs and verification of the information on the consents database. In many cases the names of CSOs differed between the NRA database, DCWW's database and the sewerage agent's database. Location of CSOs was also hampered by the quality of the original data. For example the national grid .reference (NGR) on the consents database often referred to the location of the overflow chamber rather than that of the discharge pipe.

Following field investigations it was found that some of the listed overflows could not be located due to consent duplication and unrevoked consents. There were also many*deemed consents (1989 Welsh Office) where consents were issued but the structures never built and many consents dating back to the 1960s with no plans and no N G R s .

It was therefore identified that the NRA's Consents Register won 1d require ammending and updating to more accurately reflect the t picture. This problem has subsequently been the subject of separate project; to rationalise the consents database with regard to CSO discharges.

There were also practical problems in locating discharges such as:

the restriction on manhole lifting on roads which hampered the tracing of discharges from chamber to outfall, the fact that many watercourses in urban areas were culverted and outfalls were inaccessible large growths of bankside vegetation during the summer months which obscured outfalls.

4.6 No significant use of biological data was made in the Northern Area since earlier results obtained in the SE and SW Areas had indicated that the general use of biological assessment was not appropriate for a number of reasons. Due to the transient nature of these discharges individual overflows.could not always be pinpointed bv biological assessment, the impacts of individual outfalls could nor be distinguished where groups of outfalls were closely situated and poor baseline biological quality upstream of an outfall masked the impact of the CSO.

4.7 Biological assessments of groups of overflows were included in the severity indices for the SE and SW Areas, where the evidence was conclusively linked to CSOs. However the nature of sewerage systems in the Northern Area meant that such groupings were very uncommon and biological surveys were therefore not carried out routinely ir. the North.

4.8 Other problems were specific to tidal CSO assessments. Tidal CSOs were very difficult to assess in a consistent manner because of the rigorous tidal environment and the difficulty of pinpointing the source of impact from tidal CSOs. Litter in particular can be transported over large areas during a tidal cycle and can rarely be attributed to any specific discharge. It is also difficult to link CSO discharges to bathing water quality and assess the contribution made by a single CSO to the compliance of a bathing water with the EC Directive standards. It has been assumed that where unsatisfactory CSOs discharge to designated bathing waters which fail the EC Bathing Water Directive, remedial works will be included in whatever sewerage/treatment scheme is designed to rectify the problem.

4.9 Access was also frequently a problem in tidal areas due to the larg* expanses of intertidal mud found in estuaries.

4. 10 Despite these difficulties this strategy has, for the first time, provided a detailed, objective and comprehensive picture of tho condition and environmental impact of all the CSOs in the Wclsr Region. However, although each CSO was assessed using a standarc method, the impact assessment in most cases was based on one sit-*: visit and is therefore only a "snapshot" of the status of ;>■ outfall, the discharges from which, by their very nature, m/ty fluctuate widely in quality. However, the quality audit indicaU;'- 15/06/94

The aesthetic impact criteria used for the strategy would be the mos: appropriate to use for such inspections and should be incorporated into an assessment made on every visit. It would be appropriate to issue CSO assessment proformas to all field staff which would ther. be filed with the original documentation as a running update on the CSO condition.

5.6 The CSO assessment proforma for use in the field should be ammendec and improved in the light of experience gained during this strategy so that a more objective assessment of environmental impact can be gained from each inspection. This proforma should be consistent with that recommended by the National Project Steering Group on CSC Assessment (FWR Report FR0389 Development of a Procedure for Assessing the Impact of Combined Sewer Overflows).

5.7 Following remedial work on a CSO, or group of CSOs, a reassessment of the. impact of the CSOs should be undertaken to demonstrate tha*_ the anticipated improvements have been realised. All the criteria used in this strategy should be applied to demonstrate suer, improvements.

15 outfall which formed the basis of the AMP2 costings for CSO improvements submitted to OFWAT by DCWW.

5. FUTURE WORK / ACTION PLAN

5.1 The ranked list of CSOs should be used to identify priorities for remedial work by DCWW. The Regional ranking will determine the relative priorities for each Area which will have to be weighed against other environmentally driven improvement requirements for Sewage Treatment Works and other assets. All Category 1 CSOs are "unsatisfactory" discharges and should be afforded the highest priority. Category 3 CSOs are generally not causing significant problems and will be of low or no priority, whilst the Category 2 CSOs may also be unsatisfactory but should be considered individully according to local circumstances and the level of funding available, and may merit further investigation at a later stage if their condition deteriorates.

5.2 Where a number of overflows having a significant impact are on the same trunk or branch sewerage system, then they should be considered together. In many such cases the impact will be indicative of system overload and an engineering assessment of the whole system may be necessary. In other cases, redesign and/or resetting of overflov weirs and screening may be all that is required to address the problems of individual overflows.

5.3 Environmentally protective consents should be developed and issued for CSOs in a phased manner consistent with a timetable for improvement work agreed with DCWW. DCWW will have to provide the engineering assessment of the requirements for remedial work to meet the environmentally protective consent imposed.

5.4 Dialogue should be established between the NRA and DCWW at the A r e a or District level to sort out the obvious discrepancies between the NRA's consent register and DCWW's asset databases. This can be a complex and time consuming process which should ideally be done with the assistance of the CSO Survey Officers and is therefore an urgent requirement. It is evident that DCWW are paying consent charges for discharges that do not exist, either due to consent duplication or removal of overflows, but there are also a number of overflows not on the NRA consent register for which charges should be made. There are also a significant number of overflows on both databases which have not been.found.or assessed during this strategy, some of which are unknown to DCWW and their agents. It is important that these anomalies are addressed, the dialogue is maintained as new systems are brought in and old outfalls abandoned and that databases ar<: ammended consistently. This problem is currently the subject of. a project to rationalise the NRA consents database with regard to CSO discharges and will form an ongoing commitment to updnt ing t.h'- information as changes occur to sewerage systems in the future.

5.5 Routine inspections of the worst, most problematical overt low:, should be instigated by pollution control officers in order to buil'i

1 /. that; the results of repeat visits were generally consistent. In addition, any information available from pollution control officers on the status of a CSO was included in the assessment and the worst-case score used for ranking the impact.

4.11 Once the field survey data had been collected the overflows w e r e ranked and prioritised. It was soon discovered that not all the information that was originally anticipated for use in ranking the CSOs was consistently available. The results of the original questionnaires circulated showed . that for inland CSOs 26% had incomplete data sets, and for tidal CSOs data were even more difficult to obtain and incomplete datasets were available for 41% of the outfalls. 9% of inland CSOs had no data at all to complete the ranking; these consisted mainly of unconsented discharges about which there was little or no information.

4.12 This . situation of variable data availability made prioritising the CSOs on the basis of their environmental impact very difficult, since those CSOs with lots of data tended to appear higher up the ranking than those with little data. It was therefore decided tc select only the most consistently available information on which to base the prioritisation. On this basis the five criteria described in Section 2.4 were selected as ranking criteria.

4.13 This version of . the CSO Strategy has evoloved from very ambitious beginnings, when comprehensive engineering and detailed environmental assessments, of the sewerage systems and receiving waters were planned, to the more pragmatic approach which has finally been adopted. This has largely resulted from the restricted resources available and the problems encountered in obtaining appropriate and consistent data. In the future assessments should be based on the methodology recommended by the National Project Steering Group on CSO Assessment (FWR Report FR0389 Development of b Procedure for Assessing the Impact of Combined Sewer Overflows) which builds on the experience gained from this strategy.

4.14 Implications of the EC UWWTD and AMP2 Guidelines

A preliminary interpretation of the UWWTD requirements for CSC improvements was made during the development of this strategy (the so called "645 list" or A1-C3 matrix of >15,000 PE), which was based on the NRA's interpretation of the definition of "population equivalent (PE) agglomeration" in the UWWTD. The debate over which definition of ’'agglomeration" will be used for the UWWTD has subsequently been resolved by the DoE and the result is very similar to .that proposed by the NRA, although it allows the significant expenditure required to be phased . over time with the highest priority CSOs tackled first.

4.15 This strategy will therefore form the basis of the NRA's prioritio:. for CSO improvements in Wales, in line with the AMP2 Guidelines DCWW have also run a trial costing exercise on the remedial woiv necessary to bring 12 representative CSOs up to standard. Th- results from this exercise were used to derive an average cost p*-:‘ 15/06/94 +------.------. ------+ | NRA Welsh Region W Area INLAND CSO ranked list after March 1994 revocations | +...... -......

If the SSO discharges to inland waters Part 2 of the questionnaire should be completed but not Part 3. If the SSO discharges to tidal waters (coastal waters or estuary) Part 3 of the questionnaire should be completed but not Part 2. o) Comments on site visit: All relevant information should be noted, observation of dry weather operation, more than one outlet at site, upstream pollution observed/suspected, river flow conditions, close proximity to other SS.Os/possible sources of pollution, location of biological survey sites, biological survey for a single or group of SSO*. (give details of group) etc. A photograph of the discharge' should be attached with details of the film and exposure reference numbers.

2) Environmental Impact (Inland Waters)

i) Gross Impact: : a Operation in Dry Weather Flow: To be provided by pollution control. b Frequency of substantiated public complaints: To be provided by pollution c o n t r o l . c Frequency of fish mortality: To be provided by pollution control. Low: no complaints per year. Medium: one complaint per year. High: more than one complaint per year. d Visual/aesthetic impact: To be provided by pollution control and validated during site visit. Low: sewage derived litter absent at overflow or ir. reach immediately downstream. Medium: trace amounts. High: significant a m o u n t s . e Sewage fungus present: To be provided by pollution control and validated during site visit. Low: no sewage fungus observed. Medium: sewage fungus present in mixing zone (see below for guidance on extent of mixing zone). High: sewage fungus present below mixing zone.

ii) Biological Impact: a Upstream/Downstream BMWP score: Initially evaluated on basis of River Quality Survey information for SSOs situated between RQS sample points where no other potential sources of pollution are known (consultation with pollution control required). Subsequently determined from upstream/downstream biological surveys conducted during site visits at selected overflows in the period January-April.

Sites at which surveys should be conducted are selected as follows:

- No surveys are required at sites with a Gross Impact score of 2 or more.

- No surveys are required at sites at which all questions in the Biological Impact. section (Part 2ii) have been answered during initial evaluation from RQS survey information and a Biological Impact score of 0 has been recorded.

- Surveys are required at sites where a Biological Impact score of 1 or more has been recorded during initial evaluation and SSOs are known to be present in the relevant stretch and are thought by pollution control to be a possible cause of pollution.

Upstream and downstream biological surveys should be carried out as near r»-. possible to the discharge but outside the mixing zone. In order to • b-\- outside the mixing zone, downstream samples should be taken either: - In the second riffle stretch below the discharge for a fast flowing, well-mixed river

or

- In the first riffle stretch which is at a distance of no less than 7x the river width downstream of the discharge for sluggish, poorly-mixed rivers.

In some cases a group of SSOs may discharge in close proximity to each other and share a common mixing zone. In such cases the discharges should be treated as a set and single biological surveys conducted upstream and downstream of the mixing zone for the set. Information on survey sites and the identify of SSOs in the set should be recorded in the 'Comments' sections of the questionnaires for each SSO.

b Spring/autumn BMWP score: Initially evaluated on basis of RQS information where no other potential sources of pollution are known. The score for chii answer should only be used if question 2iia shows that an impact i.\ associated with the discharge (score 1 or 2).

c Observed/expected BMWP score: Initially evaluated by comparison of BMWr score recorded during RQS with expected score predicted by RIVPACS analysis. The score for this answer should only be used if question 2i ia shows that an impact is associated with the discharge (score 1 or 2).

Defining Satisfactory and Unsatisfactory CSOs

The guidance outlined below is provided for the following reasons:

1. To ensure a consistent approach in determining what is, and whatsis not, an unsatisfactory CSO. from the impact assessment scores provided by the CSO Strategy.

2. To differentiate between the official definition of "unsatisfactory" according to the AMP2 Guidelines, and deciding where to draw the line for practical purposes in requiring remedial works.

3. Since there is a difference implied in 2. above it may be necessary to reassess some of the subjective scores given to the CSOs in the Strategy to place them officially into "unsatisfactory" or "satisfactory" categories in the future.

The definition of an unsatisfactory CSO according to the AMP2 Guidelines is one which fails any one of the criteria listed in the guidelines. It is not necessary to repeat those criteria here as we used all the available information to make the ranking criteria reflect the AMP2 Guidelines as closely as possible.

Therefore, if a CSO scores an X on any single ranking criterion it is deemed to be unsatisfactory according to the AMP2 Guidelines.

However, there are many CSOs.which only score an X either on criterion 4 or on criterion 5, and on no other criterion.

Criterion 4 relates to LTRQO impact, and while in some instances CSOs can be directly linked to LTRQO failures (either individually or in groups) it seems unlikely that a CSO which is otherwise entirely satisfactory will be the sole cause of a LTRQO failure.

Similarly criterion 5, which relates to an impact on uses, has a very broad range of levels of impact - from detrimentally affecting a potable supply to compromising the amenity value of a footpath. It is again unlikely that an otherwise satisfactory. CSO will be the sole cause of a significant impact on a use.

With the benefit of hindsight it is easy to see how the original CSO Strategy questions could have been broken down further to make the answers more sensitive to the actual situation, but unfortunately we have not had the opportunity to revisit the responses originally provided in most cases. It may be appropriate to do this in future now that we can identify the CSOs .at which this situation arises.

From a practical point of view, and particularly for the purposes of directing Dwr Cymru's capital investment programme, we need to take /i . slightly more pragmatic view of the definition of an unsatisfactory CSO so chat those described above as having only a minor impacc are noc taken out of context.

For this reason boundaries defining satisfactory, unsatisfactory and "minor impact" CSOs are proposed, and the codes which apply in each caCegory for both tidal and inland CSOs are given below.

Boundaries Defining Decrees of Unsatisfactory CSOs

1. Inland CSOs

a) Unsatisfactory CSOs:

In the ranked order the codes will range from XXXXX to ZXZZX and XZYZZ cc ZXZZZ

A CSO will be deemed unsacisfaccory if ic has one of che following codes:

XXXXX XXZZZ XXXXZ XZYXZ XXXZX XZYZX XXZXX XZZXZ XXXZZ XZZZX XXZXZ ZXXZZ *XXZZX zxzxz XZYXX ZXZZX XZZXX XZYZZ ZXXXZ xzzzz ZXXZX zxzzz ZXZXX b) Minor Impact CSOs:

In the ranked order the codes will range from ZZYXX Co ZZZXX and ZZYXZ cc ZZZZX.

A CSO will be deemed to be having only a minor impacc (and not be a priority for investment), although will officially be classed as unsatisfactory under the AMP2 Guidelines, if it has one of the following c o d e s : ZZYXX ZZYZX ZZZXX ZZZXZ ZZYXZ ZZZZX * t c) Satisfactory CSOs:

In the ranked order the codes will range from ZZYZZ to ZZZZZ.

A CSO will be deemed Co be sacisfaccory if ic has one of che following c o d e s : ZZYZZ ZZZZZ .

31 2. Tidal CSOs

a) Unsatisfactory CSOs:

In the ranked order the codes will range from XXXXX to ZXZZZ

A CSO will be deemed unsatisfactory if.it has one of the following codes:
