Utilities Appraisal Report Land South of Netherhampton Road, Harnham

1 Introduction

The Brief

1.1.1 Peter Brett Associates, now part of Stantec (PBA), has been commissioned by Bovis Homes to prepare a Utilities Appraisal Report in support of an outline planning application for the Land South of Netherhampton Road, Harnham, near Salisbury in Wiltshire.

1.1.2 This Utilities Appraisal Report will outline the utility issues in relation to the proposed site and will also identify the requirement for new utility infrastructure, potential upgrade/reinforcement works, diversion/abandonment works or the need for further investigation/modelling.

1.1.3 The proposed development comprises 640 residential units, a retail unit, a 2-form entry primary school and employment uses. A copy of the proposed masterplan is included in Appendix A. This report addresses Statutory Utilities only (electric, gas, telecoms and water and foul drainage), and does not include any “privately” owned and maintained utility infrastructure that may or may not be present on site.

Site Location

1.2.1 The proposed site is currently greenfield agricultural land. The land is bounded to the north by Netherhampton Road, to the east and west by existing retail units and to the south by greenfield land. A detailed site location plan can be found in Appendix B.

The Report

1.3.1 This report has been prepared to consider the proposed utility infrastructure and any constraints the existing utilities may present to the proposed development. It provides the following information:

The existing utility infrastructure in the vicinity of the development.

Diversionary/protection works anticipated to the existing utility infrastructure to facilitate the development.

Details of the responses received in respect to capacity enquiries.

The utility infrastructure that would be required to supply the new development.

1.3.2 PBA approached the incumbent utility providers requesting that they undertake capacity and new supplies investigations based on everyday typical usage rates for 640 residential units. In addition, the following utility loading demands have been used for non-domestic units:

Utility Medium Usage Potable Water Foul Drainage Peak Electricity (kVA) Gas (kW) (l/s) (l/s)

3 Electricity – Scottish & Southern Electricity Networks

Existing Electrical Infrastructure

3.1.1 Scottish & Southern Electricity Networks (SSEN) records indicate 132kV overhead infrastructure and associated towers cross the western part of the site in a north-south direction.

3.1.2 Records also indicates HV (11kV) overhead infrastructure and associated poles cross through the northern section of the site, running in an east-west direction from the Netherhampton Business Park substation to an existing commercial unit. From this overhead infrastructure, an underground HV (11kV) cable runs to Dunns Seeds substation in Hannan Business Park, located outside of the north eastern development boundary.

3.1.3 33kV overhead infrastructure and associated towers cross the far eastern boundary and continues to Netherhampton Business Park substation.

3.1.4 LV overhead infrastructure is located along Netherhampton Road in the northern footway.

Diversionary and Protection Works

3.2.1 SSEN has confirmed that the HV (11kV) overhead infrastructure crossing the site, will require diverting underground through the development to facilitate the development requirements.

3.2.2 It is anticipated, that the 132kV and 33kV overhead infrastructure crosses over land dedicate to open space and will therefore remain in situ.

3.2.3 SSEN has confirmed that there is a 15m easement from the mid span to any building along the 132kV overhead infrastructure, and no excavations within 10m of the tower legs.

3.2.4 It is also recommended that the client consult with SSEN’s wayleave department, to confirm if there is a wayleave or easement agreement is in place for the existing HV (11kV) overhead infrastructure crossing the site. This may mitigate customer contribution towards the cost of diverting the existing HV (11kV) overhead infrastructure.

Proposed Utility Infrastructure

3.3.1 SSEN has been requested to undertake a capacity investigation based on a typical supply demand for 640 residential units and non-domestic loading requirements as detail in table 1.1.

3.3.2 SSEN has confirmed that in order to provide the development with the required electrical demand, a 1x 800kVA substation and up to 6 x 500kVA substations will need to be established onsite. SSE advised that the substations will require an area of approximately 4m x 4.5m, with 24-hour vehicle access, and should be located 6m away from any building.

3.3.3 In addition, it has been confirmed by SSE that the site is classed as a ‘Cold’ site, i.e. no earthing is required within the ground around the perimeter of each substation, and no additional safety clearances are required from the proposed substations.

3.3.4 SSEN has provided a budget cost of to supply HV 11kV and LV infrastructure to the proposed development.

3.3.5 A copy of the response from SSEN is included within Appendix D.

Utilities Appraisal Report Land South of Netherhampton Road, Harnham

Electric Vehicle Charging

3.4.1 The government have announced their intention to withdraw the internal combustion engine from road transport by 2040 (The Clean Growth Strategy – October 2017). This will drive a shift towards ultra-low emission vehicles and alternative low carbon technologies, i.e. electric vehicles.

3.4.2 Therefore, developers are being encouraged to provide electric vehicle charging points (EVCP’s). To minimise future disruption to parking arrangements and electric connections, development masterplans should be designed such that EVCP’s can be provided or can be retrofitted with minimal disruption.

3.4.3 At this time PBA have not included any allowance for car charging points within the load calculations for the development site. The local authority’s current requirements state the need for an additional 10 public access charging points. This will be confirmed once the final EVCP strategy has been agreed between the developer and local authority.

4 Gas – Southern Gas Networks

Existing Gas Infrastructure

4.1.1 Southern Gas Networks (SGN) records show there is no gas infrastructure within or in the immediate vicinity of the proposed development.

4.1.2 The nearest gas infrastructure to the development, is an existing 125mm polyethylene (PE) low pressure (LP) main which is located approximately 310m to the east of the site within Netherhampton Road.

Diversionary and Protection Works

4.2.1 There are no diversionary or disconnection works required to the existing gas infrastructure.

Proposed Utility Infrastructure

4.3.1 SGN has been requested to undertake a capacity investigation based on a typical supply demand for 640 residential units and non-domestic loading requirements as detail in table 1.1.

4.3.2 In response, SGN confirmed that there is insufficient capacity in the existing 125mm PE LP gas network within Netherhampton Road to supply the proposed development requirements. Therefore, reinforcement of the gas network will be required in order to supply the development with gas.

4.3.3 The nearest gas network with sufficient capacity to supply the proposed development without the need for reinforcement, is an 8” steel (ST) medium pressure (MP) main located approximately 2,400m east of the development.

4.3.4 A copy of the response from SGN is included within Appendix D.

Dear Ms May

Clearances to overhead tower line at Netherhampton Road, Salisbury, Wiltshire SEPD 132kV overhead circuit: Mannington to Salisbury MS Line Towers MS96 to MS97 (1 spans, 2 towers)

I write to you regarding our recent correspondence and discussions concerning the necessary safety clearances to be observed to the overhead 132kV power lines at Netherhampton Road, Salisbury, during the proposed works.

The overhead tower (pylon) lines in the area in which the work is planned to be carried out are known to Southern Electric Power Distribution plc (SEPD), the owner and operator of the lines, known as the MS line. The trading name for SEPD is Scottish & Southern Electricity Networks (SSEN). The MS line circuits connect between SSEN’s Mannington and Salisbury sub-stations and form an integral, important part of SSEN’s distribution infrastructure in the Wiltshire area.

I am responding to you now formally on behalf of SSEN in respect of the planned works as regard the 132kV overhead line circuits only but please note and as I know that you are already aware, that there are also other circuits in the immediate vicinity of the proposed works operating at other voltages. The enclosed annotated GIS site plans show the

132kV circuits marked in black, 33kV circuit in green and11kV circuits are coloured red. Clearance to and from the 33kV and 11kV circuits will also need to be observed in addition to clearance to the 132kV overhead circuits if there are no plans to divert or underground

Inveralmond House, 200 Dunkeld Road, Perth PH1 3AQ ssen.co.uk Scottish and Southern Electricity Networks is a trading name of: Scottish and Southern Energy Power Distribution Limited Registered in Scotland No. SC213459; Scottish Hydro Electric Transmission plc Registered in Scotland No. SC213461; Scottish Hydro Electric Power Distribution plc Registered in Scotland No. SC213460; (all having their Registered Offices at Inveralmond House 200 Dunkeld Road Perth PH1 3AQ); and Southern Electric Power Distribution plc Registered in England & Wales No. 04094290 having its Registered Office at No 1 Forbury Place 43 Forbury Road Reading RG1 3JH which are members of the SSE Group www.ssen.co.uk those lower voltage circuits. Please contact our Lead Wayleave Officer, Madeleine Pain (02380 817327) based in our regional office.

Please note that any low voltage circuits present are not shown on the enclosed site plans. Your client is advised to contact the local SSEN Poole depot (01202 784600) to discuss both low voltage, 11kV high voltage circuits installed near the planned works area. Lower voltage circuits are often installed on wooden poles or other types of support or as underground cable circuits.

Please note that the widths of the 132kV, 33kV and 11kV overhead lines are not shown on the site plan drawing only their centre line and route.

You are reminded and advised that the MS lines are ELECTRICALLY LIVE and operating at 132,000 volts (132kV).

Before any works commence, your client will need to establish a safe working and operating method as it will not be possible for SSEN to switch the 132kV lines out of service for an extended period. You should assume that all circuits will be operating and live unless advised otherwise by an SSEN engineer.

Please note that no excavations over a depth of 600mm may take place within 10 metres of a tower (pylon) leg without prior consultation with and agreement received from SSEN.

Health & Safety Executive Guidance Note GS6 “Avoiding danger from overhead power lines” is available as a free to download document from the H&SE website and provides advice on the safety precautions required when working close to overhead power lines. Similarly, H&SE publication HSG47 “Avoiding danger from underground services” can be downloaded from the H&SE website. HSG47 provides advice and guidance when working near buried services including electricity cables and other apparatus. Both documents should be consulted as and when necessitated by the requirements of the proposed works and the guidelines contained therein strictly observed during the works programme. The work site Health and Safety Plan should address the safety requirements necessitated by working adjacent to or under the overhead lines and other locally installed equipment.

Enclosed is a line profile drawing for the relevant towers and spans of the MS line being towers (pylons) MS96 to MS97 as I identify these to be the towers and intermediate spans operating at 132kV of immediate interest to you regarding this enquiry. The scales used on the extracts are 1:2000 horizontal and 1:200 vertical. The line profiles are valid as at the time of the line survey inspection, which in this case is January 1990.

Should original ground levels at the site have been altered substantially in recent times and particularly since the date of the line profile surveys, then the enclosed calculations could be incorrect. In that instance, the overhead line(s) in this area would possibly need to be resurveyed before SSEN could advise the clearances information you now seek with greater certainty. It is suggested that the ground heights above Ordnance Datum (AOD) be validated on-site against those figures provided at column 2 on the enclosed spreadsheets, which figures have presently been derived from the SSEN line profile records.

There are two curved arc lines on the profile drawings. The upper solid line curve represents the lowest strung conductor cable(s) hanging in still air and the circuits operating at 50° Celsius. The lower dotted line curve represents a “virtual line” 6.7 metres below the lowest strung conductor(s) and denotes the statutory minimum permitted clearance between the conductors and the ground. This is known as the ground safety clearance. In other words, if ground levels have been altered since the date of the line profile surveys, those ground 2 levels would still have to be below the statutory minimum permitted ground safety clearance line.

Please also find enclosed a spreadsheet table of calculations of the ground clearances and safety clearances for the overhead 132kV lines measured at intervals between the towers. The measurement intervals are for calculation purposes only and are not intended to represent the foot print or plan of the proposed works. Also enclosed is a sketch mp1689 which graphically explains the figures given in the spreadsheet table.

By way of example and hopefully helpful explanation, from reference to column 4 of the enclosed spreadsheet, you will note that the closest point from ground upward to the lowest conductor on the MS96 to MS977 span, taken from amongst those measurement points selected, is 9.5m at 100 metres from MS96 toward MS97. Please note that this measurement is derived from the line profile drawing and not from on-site inspection.

Please note that a safety clearance to an overhead line conductor live and operating at 132kV must be observed always. This distance, known as the conductor safety clearance, is a minimum of 3.6 metres.

The conductor safety clearance distance is that as recommended by the Energy Networks Association (ENA) and is also the adopted SSEN policy distance. However, wherever possible, it is strongly suggested that the site safety plan includes an additional factor of safety and that the 3.6m clearance be extended to 4.5 metres. The clearances provided with this letter assume that the greater safety clearance distance of 4.5m will be adopted.

The conductor safety clearance is measured from any position at which a person might stand whether or not that position is generally a permitted one or one that might otherwise be ordinarily made use of. Such a position or point includes those afforded by permanent structures such as a building or a temporary one such as, for example, scaffolding, cranes, lifting equipment, grading machines, a ladder placed against a structure or vegetation capable of supporting it or on top of transient equipment such as a vehicle.

The conductor vertical safety clearance is the figure in column 6 of the spreadsheet so, for example, at the 1000m point from MS96 toward MS97, the point noted in the above paragraph, the Safety Clearance Zone Height above ground is reached vertically at 5.0 metres if ground levels AOD have not altered since the line survey in 1990. Please remember that the minimum conductor safety clearance distance of at least 3.6m MUST be adhered to always.

The conductor safety clearance distance applies to the conductors hanging vertically in still air (columns 4 and 6 of the enclosed spreadsheet) but also throughout the arc described by the conductors when influenced by a side wind pressure. Side wind pressure will cause the conductors to blow out (“swing out”) from perpendicular. The blow-out figures are given in column 12 of the spreadsheet. Please note that as a conductor is blown sideways, it lifts, thus often but not always increasing the clearance distance to ground level. The safety clearances define the maximum height of any point on which a person might stand whether otherwise ordinarily permitted or not.

To ensure that any lifting or excavation equipment proposed to be used during the works cannot infringe upon the conductor safety clearance that consideration is given to fitting slew and height restriction to the lifting, excavation or any other equipment likely to be used near the overhead lines.

OD refers to (Above) Ordnance Datum representing the mean height above sea level.

The figures in column 10 are used when the proposed height of a structure whether permanent or temporary, would infringe the vertical clearances. In those circumstances the structure must be placed to the side of the line rather than under them. Column 10 gives the required minimum distance when measured from the tower centre line of any permanent or temporary construction or transient, mobile equipment such as a crane, other lifting equipment or mechanical digging and trench excavating machines. Such placement of buildings or temporary equipment to either side of the centre line recognises the width of the Safety Clearance Zone Corridor.

Any structure must always be outside the Safety Clearance Zone Corridor under both still air and blown-out conditions if the conductor safety clearance is likely to be infringed by the structure. As noted earlier above, this also applies to any temporary structures erected during construction of the main permanent structure(s).

In all usual circumstances, SSEN's operators and maintainers of the overhead lines, must be advised before any work starts and be given the opportunity to contribute to the site safety briefing. My colleagues Mac Macdonald, Project Manager Overhead Service’s and Martin Bailey, 132kV Maintenance & Inspections Manager representing the maintainers of the lines and Chris Burton, Strategic Investment Manager SSEN representing the operator of the lines, are the relevant persons to be consulted. I am copying this letter to Mac, 07767 850774, Martin 07500 912062 and Chris on 7767 850088.

In the first instance, technical discussions should please continue to be forwarded to me at the above Forbury Reading office address either in writing or by email or telephone.

Thank you for consulting Southern Electric Power Distribution plc trading as Scottish & Southern Electricity Networks. If I can be of any further assistance to you about your enquiry, please do let me know.

Yours sincerely,

Ian D’Souza Project Engineer Strategic Investment South Scottish & Southern Electricity Networks

For the attention of James Hicks

Site: Land south of Netherhampton Road, Harnham Proposal: 660 residential units, retail unit, 2-form entry school and employment area. Our Ref: SU12NW/ 50

Thank you for your enquiry. Please find attached an extract from our records showing the approximate location of our apparatus within the vicinity of the site.

Existing Sewerage Infrastructure Foul flows from the Netherhampton / Harnham catchment are conveyed eastwards via a network of sewers and pumping mains to an existing 375mm public foul sewer which crosses the Rivers Nadder and Avon to join the sewer system serving central Salisbury, prior to discharge at the sewage treatment works at Petersfinger. Predicted foul flows from a development of this size will represent a significant increase in foul flows within this catchment.

Proposed Sewerage The site must be served by separate systems of drainage.

Foul Drainage The public foul sewer in Netherhampton Road is 150mm diameter, however a development of this scale will require a larger diameter sewer connection and the nearest size for size point of connection would be the 300mm sewer at MH SU1229 7101. CL47.42 IL45.69 Co-ordinates 412758,129183 There is limited available capacity within the downstream foul sewer network and upon grant of planning, Wessex Water will undertake to consider the impact of the additional flow. We will need to work closely with the developer and the planning authority to ensure that we can plan design and construct any necessary improvements to accommodate permitted development.

Surface Water Drainage Surface Water to be disposed of in accordance with SuDS Hierarchy and NPPF Guidelines and should be via infiltration or directed to local land drainage systems. Points of disposal and maximum discharge rates are to be agreed with the Lead Local Flood Authority with supporting flood risk measures. Surface water connections to the public foul sewer network will not be permitted. Land drainage run-off shall not be permitted to discharge either directly or indirectly to the public sewerage system.

Water Infrastructure The water main in Netherhampton Road is 4’’ diameter, however a development of this scale will require a larger diameter connection and the nearest size for size point of connection would be the 180mm water main in Upper Street. Approx. co-ordinates 412890,129188 There is limited capacity in the local water network and upon grant of planning, Wessex Water will undertake to consider the impact of the additional demand. We will need to work closely with the developer and the planning authority to ensure that we can plan design and construct the necessary improvements to accommodate permitted development. The southern part of the site appears

1 to be at a higher elevation and the possible need for a booster station on site will also be determined by the model.

I trust that you find the above of use. Wessex Water will need a suitable period once outline planning consents are secured to develop a detailed design and construct any sewer or water network upgrades. Prioritising and programming these works will require consultation with all stakeholders to ensure that capacity improvements can be delivered to match the rate of development. It is important that we are kept informed of proposals and programme at all stages of the planning and development process so we may review and plan as necessary.
