1.0 INTRODUCTION
1.1 Mewies Engineering Consultants Ltd (M-EC) has been commissioned by Martin Grant Homes and Harcourt Developments to undertake a Utilities Report for a proposed residential development on Land off Newton Pagnell Road, Wootton, Northamptonshire (Hampton Green). A site location plan is provided in Appendix A and a site layout plan is contained within Appendix B.
1.2 A description of the development is provided below:
‘’Outline planning permission for up to 525 dwellings, open space, children’s play spaces and associated infrastructure. All matters are reserved, expect for access.’’.
1.3 The purpose of this report is to establish how the proposed development will be serviced with key utility supplies, whether diversion or protection of existing apparatus may be required and estimated costs for service connection and works, where available. Despite the development quantum consisting of up to 525 dwellings, all developer enquiries to key Statutory Undertakers have been undertaken for a development quantum of 500 dwellings and a primary school. The capacity required for a primary school exceeds the requirement for 25 residential dwellings therefore, the responses received within this report can be considered robust.
1.4 The costs obtained from key Statutory Undertakers relate to designs available as part of an outline planning application. Further updated searches will be required at the reserved matters and detailed design stages.
1.5 Consultation has been undertaken with key Statutory Undertakers to establish:
• Available capacity within existing infrastructure; • Required capacity improvement works to accommodate the development; • Required diversions of infrastructure to accommodate the proposed development; • Any required easements; • Service connection locations; and • Service connection costs.
1.6 Consultation has been undertaken with the following Statutory Undertakers: • Anglian Water (clean and foul water provider for Wootton); • National Grid & British Gas (gas);

2.0 EXISTING SERVICES
Foul Water 2.1 Anglian Water (AW) provides foul water sewerage for the Wootton area. A Developer Enquiry response and sewer records, supplied by AW, are included in Appendix C.
2.2 The sewer records show that there is an existing 150mm foul sewer located along the western side of Lady Hollows Drive. This sewer runs within the residential streets to the west of the development site before diverting northbound along Newport Pagnell Road at the junction with Lady Hollows Drive. Further 150mm sewers are located to the west of the site within The Choakles and The Ashes. It is noted that S104 surface water sewers which are 225mm in diameter run alongside the 150mm public foul sewers to the west of the site.
2.3 A 150mm public foul sewer which connects to a 225mm public foul sewer is located within Gowerton Road. A 450mm surface water sewer which connects to a 600mm surface water sewer is also located within the carriageway. A 300mm public foul sewer runs north from the Gowerton Road/Landimore Road roundabout from manhole reference 5600. A surface water sewer of similar size also begins here at manhole reference 5551.
2.4 No sewer apparatus owned by AW is located within the boundaries of the site.
Clean Water 2.5 AW provides clean water supply to the Wootton area. A Developer Enquiry response and water mains records, supplied by AW, are included in Appendix C.
2.6 The water mains records show there is a 450mm clean water main which runs directly through part of the site from east to west, just north of The Green. This main then diverts north close to the junction with Newport Pagnell Road before connecting onto a 4’’ main along the western side of the carriageway. The 450mm main continues to proceed northbound supplying properties off Pagnell Court.
2.7 An 8’’ clean water main runs along the eastern side of Lady Hollows Drive. Smaller mains which run within residential streets connect to this main providing a supply to properties located to the west of the site.
Gas 2.8 National Grid operates gas mains within Wootton. National Grid correspondence and apparatus plans are included in Appendix D.
Report Ref: 20168/10-17/3992 Page 6 Utilities Report – Land off Newport Pagnell Road, Wootton
2.9 The apparatus plan shows a number of Low Pressure (LP) gas mains within the residential streets located to the west of the site. A Medium Pressure (MP) gas main runs from the Middle Greeve/Lady Hollows Drive junction towards Newport Pagnell Road where it then diverts north along the western verge of the carriageway. A further MP main is noted along Gowerton Road which provides a supply to the industrial estate to the north of the site.
2.10 National Grid plans confirm that none of their apparatus is located within the site boundaries.
Electricity 2.11 Western Power Distribution (WPD) operates the electricity distribution network in the Wootton area. WPD correspondence and apparatus plans are included in Appendix E.
2.12 The apparatus plan supplied by WPD indicates that there is an overhead 33kV cable which enters the site at its western corner before exiting the site heading southbound. Underground HV and LV cables are located within the residential streets to the west of the site which provide a supply to residential properties.
Telecommunications 2.13 BT Openreach telecoms apparatus plans are included in Appendix F.
2.14 A review of the apparatus plans indicates the presence of underground apparatus located along the eastern verge of Newport Pagnell Road. Further underground cables are located within the residential streets located to the west of the site.
2.15 Underground cables are also noted along the northern verge of Gowerton Road which connect to the industrial estate to the north of the site.
2.16 Virgin Media confirm that none of their apparatus is located within close proximity of the site. Confirmation of this can be found in Appendix G.

3.0 SERVICES SUPPLY
Foul Water 3.1 AW has confirmed that foul drainage from the development is in the catchment of Great Billing Water Recycling Centre, which currently has capacity to treat the flows from the development site. A Developer Enquiry Response from AW can be found within Appendix C.
3.2 AW have assessed the development proposals and their desktop study has indicated that a direct connection to the public foul sewer network is likely to have a detrimental effect on the existing system. Therefore, further hydraulic modelling work is required to enable AW to provide a feasible drainage solution for the development. In accordance with the Water Industry Act a suitable solution will be identified and foul drainage capacity is not a constraint to development.
3.3 Previous modelling work was carried out on the basis of the foul flows from 450 homes to be connected at the manhole reference MH5901 on Newport Pagnell Road. The study concluded that the development will cause detriment to the capacity of the sewer system and will result in increased flood risk downstream of the proposed connection point. In order to mitigate the impact of the proposed development, AW have recommended providing and offline storage of capacity 40m3 in the green area near Wooldale Road. The estimated cost for the proposed off-site reinforcement solution is £269,750.00 with an indicative developer contribution of £29,796.00. Updating the foul hydraulic modelling would only refine the amount of offline storage.
3.4 AW can confirm, at present, the network has available capacity for the development surface water flows. The connection point for the surface water can be made to manhole 6551 at NGR SP7767857590 to the north of the site.
3.5 Foul water and surface water drainage options have been considered by M-EC within Section 7.0 of their Flood Risk Assessment (Ref: 20168/06-17/3941 Rev A) and design options are presented as part of the report.
Clean Water 3.6 AW has confirmed that there is sufficient capacity to supply the proposed development with clean water therefore, reinforcement works are not required.
Report Ref: 20168/10-17/3992 Page 8 Utilities Report – Land off Newport Pagnell Road, Wootton
3.7 AW has confirmed that a suitable connection point is located within the existing 180mm water main situated along Newport Pagnell Road at National Grid Reference (NGR) SP7774956796. Furthermore, AW confirms that a contribution will be required for their Strategic Water Mains scheme which is calculated by the anticipated flows required for the development. AW have provided a full breakdown of these costs within their Developer Enquiry found in Appendix C.
Gas 3.8 National Grid has confirmed that there is sufficient capacity within the existing network to supply the site with gas, without the need for off-site capacity improvement works.
3.9 Grid has confirmed that the development can be connected to the Medium Pressure gas main located 148 metres from the western boundary of the site. A suitable point of connection has been highlighted by National Grid and included within Appendix D.
3.10 GTC has supplied a budget cost to supply gas connections to the proposed development. Correspondence is included in Appendix H.
3.11 British Gas has supplied a budget cost to supply gas connections to the proposed development. Correspondence is included in Appendix I.
Electricity 3.12 WPD has provided a budget estimate to supply the proposed development with electricity. The budget estimate stated that the site will require two new 800kVA package substations along with a new 11kV circuit breaker at the local primary substation to facilitate this. All associated cables and reinforcement works are included within the budget estimate.
3.13 GTC has supplied a budget cost to supply electricity connections to the proposed development. Correspondence is included in Appendix I.
Telecommunications 3.14 BT Openreach have provided their budget cost of £00.00 to provide Fibre cables within the site. BT confirm that an estimated fibre broadband speed range of up to 300mb would be available to the site. At these speeds, residents would have no problem undertaking everyday activities including streaming music, HD videos and online gaming.
Report Ref: 20168/10-17/3992 Page 9 Utilities Report – Land off Newport Pagnell Road, Wootton
3.15 BT confirms that if fibre connectivity to the development should not be pursued, the current estimate broadband speed rage would be a maximum of 8mb. A copy of BT’s connectivity assessment can be found within Appendix F.

4.0 DIVERSIONS AND PROTECTION OF APPARATUS
Clean Water 4.1 AW apparatus plans confirm that a 450mm clean water main runs through the site from west to east, just north of The Green. AW have confirmed that an easement of 4.5m either side of the centre point on this main must be adopted whereby no building or permanent structure can be built.
Electricity 4.2 WPD apparatus plans highlight that there is a 33kV cable which enters the site at its western corner. WPD have confirmed that based on the proposed site layout, this cable will not require diverting. The 33kV cable will be placed underground within the highway therefore, no diversions will be required.
Telecommunications 4.3 A review of the BT apparatus plan indicates that there is underground apparatus located along the eastern side of Newport Pagnell Road, close to the proposed site access junction. BT advise that detailed access drawings should be submitted before they can proceed with calculating a budget estimate for the site.

If it is not possible to avoid our assets then the water main/sewer may need to be diverted in accordance with Section 185 of the Water Industry Act (1991). We have a duty to divert our sewerage infrastructure if requested to do so although this would be at your expense. You will need to make a formal application if you would like a diversion to be considered. A copy of the section 185 diversion application form can be found at www.anglianwater.co.uk/developers
Due to the private sewer transfer in October 2011 many newly adopted public used water assets and their history are not indicated on our records. You also need to be aware that your development site may contain private water mains, drains or other assets not shown on our records. These are private assets and not the responsibility of Anglian Water but that of the landowner.
Pre-Planning Report Thursday, 08 December 2016
Section 3: Water Supply
In examining the available capacity for your development site we assess the capacity and costs for two categories of water main. These are:
Strategic – these are the offsite potable water mains which deliver water within an area to a large number of development sites often across a number of towns. The strategic provision of these water mains enables us to provide of the cheapest solution across a large geographical area.
Local reinforcement – these are the offsite potable water mains that connect your site to the closest available public water main. Alternatively, reinforcement may be needed to protect existing houses against the loss of water or water pressure.
On most sites we also have two categories of water mains the Spine Mains and Housing Estate Mains (HEMS). To support your budgeting arrangements we have also examined the estimated cost for delivering the onsite water mains needed for a site of your size.
Water Supply Network
The water supply to the proposed development site can be provided from the existing mains as listed below. The water main has adequate capacity for your development site. Anglian Water cannot reserve capacity and therefore you are recommended to formally apply for a connection at your earliest convenience. Please note that available capacity in our network can be reduced at any time due to increased requirements from existing businesses and houses as well as from new housing and new commercial developments.
The connection point for the site will be from the existing 180mm HPPE water main in Newport Pagnell Road, Hackleton at National Grid Reference (NGR) SP7774956796.
Water Budget Costs The costs provided in this report are based on the current information available. These costs are provided as an indicative estimate to help inform you on a budget for supplying water to your site.
• The strategic costs are based on a proportion of the total strategic scheme cost. These costs are calculated based on the flow rate that your development requires as compared to the total flow rate that the strategic main has been designed against.
• The local reinforcement costs have been calculated based on the typical costs of providing a length of water main across a similar distance as required for this development site.
• The onsite Spine mains and HEMS costs are provided based on historic Anglian Water construction information.
Pre-Planning Report Thursday, 08 December 2016
Based on these estimated and predicted costs, the cost to provide water to your site:
Predicted costs for supplying water to your development
Strategic Water Mains Based on N/A
Estimated Local reinforcement Mains N/A
Estimated Onsite Water Mains Onsite water mains costs £ 300,000.00
Total Cost for providing the water infrastructure £ 300,000.00
The above table provides an estimated breakdown of the costs to supply the water infrastructure. A more detailed cost provision will be provided following a formal application for a new water mains or water connection.
Financing your water costs
You will be required to partly contribute towards the cost of supplying water to your site. The amount that you contribute is dependent on your preferred method of financing the site. The Water Industry Act enables you to finance the water mains via either the relevant deficit or discounted aggregate deficit. A full breakdown of these methods is provided on our website at www.anglianwater.co.uk/developers.
In essence, the two deficit options allow us to offset future revenue (from the end customer after they purchase your houses) from the scheme cost. The scheme cost is determined as a hypothetical fixed rate loan provided over 12 years. The two statutory options are:
1. Relevant deficit. This takes the actual annual revenue offset from the actual annual scheme cost repayment. The difference is paid every year over the first twelve years of your site or until the revenue exceeds the annual scheme cost.
2. Discounted aggregate deficit. This enables us to offset the estimated future revenue from the scheme cost. This is calculated over the first twelve years of your site and a commuted sum is calculated as an upfront net present value amount.
Pre-Planning Report Thursday, 08 December 2016 Your estimated contribution towards the construction costs are provided in the table below:
Scheme Title: Newport Pagnell Road, Hackleton Developer: M-EC Consulting Development Engineers
Year Occupation Rates Estimated Construction costs 1 0 Onsite water £ 300,000 2 50 Offsite water £ - 3 150 Estimated Scheme Cost £ 300,000 4 250 5 350 Your estimated contribution towards construction costs 6 450 Relevant Deficit £ 70,358 7 500 Discounted Aggregate Deficit £ 66,536 8 500 9 500 10 500 11 500 12 500 Total 500
In addition, you also have the ability to construct the onsite water mains under a self-lay agreement. In such cases, an Asset Payment is made by Anglian Water following commissioning and adoption of the assets. The Asset Payment is calculated as required in the Water Act 2003. For more information on the self-lay of water mains please see www.anglianwater.co.uk/developers/self-lay.
You will also need to budget for both infrastructure charges and connection costs. The 2016/17 charges are:
Infrastructure Charge £354.00 per connection
Please note that we offer alternative types of connections depending on your needs and these costs are available in our annual charges booklet, which can be downloaded from www.anglianwater.co.uk/developers/charges.
Pre-Planning Report Thursday, 08 December 2016
Section 4: Water Recycling Services
In examining the used water system we assess the ability for your site to connect to the public sewerage network without causing a detriment to the operation of the system. We also assess the receiving water recycling centre and determine whether the water recycling centre can cope with the increased flow and influent quality arising from your development.
Water Recycling Centre The foul drainage from the proposed development is in the catchment of Great Billing Water Recycling Centre, which currently has capacity to treat the flows from your development site. Anglian Water cannot reserve capacity and the available capacity at the water recycling centre can be reduced at any time due to growth, environmental and regulation driven changes.
Used Water Network Anglian Water has assessed your proposals and our desktop study has indicated that a direct connection to the public foul sewer network is likely to have a detrimental effect on the existing system. Therefore further hydraulic modelling work is required to enable Anglian Water to provide you with a feasible drainage solution for your site.
This site has previously been modelled on the basis of both 200 and 450 homes respectively and the need for mitigation was established. The desired method of progressing forward would be to underwrite for detailed design. Should you wish to move forward with an addendum of hydraulic modelling to your pre-planning report, we would be happy to provide a cost and timescale. This additional work would be at the cost of the developer.
Max Shone is our senior growth planning engineer for this area and will be responsible for any additional work. For your reference, Max can be contacted on 07712 876 139 or at [email protected]
Anglian Water will request a suitably worded condition at the planning application stage to ensure the strategy is implemented to mitigate the risk of flooding.
Please do let us know how you wish to proceed.
Surface Water Disposal Anglian Water has assessed a connection to the public surface water sewer as per your attached documentation. We can confirm that this is acceptable as, at present, the network has available capacity for your flows. The connection point for the surface water will be to manhole 6551 at NGR SP7767857590 to the north of your site at a discharge rate of 85.32 l/s.
Pre-Planning Report Thursday, 08 December 2016 Anglian Water has also assessed an alternative connection for surface water flows to the south of your site as requested. The sewers to the south west of your site are presently privately owned subject to a completed Section 104 application. Anglian Water therefore cannot recommend a connection there and permission to do so would have to be sought by the owner of this sewer.
It is our understanding that the evidence to confirm your compliance with the surface water hierarchy is not currently available. It is your responsibility however to provide evidence to confirm that all alternative methods of surface water disposal have been explored and these will be required before a surface water connection can be agreed. This is subject to satisfactory evidence which shows the surface water management hierarchy, as outlined in Building Regulations Part H, has been explored. This would encompass the results from the site specific infiltration testing and/or confirmation that the flows cannot be discharged to a watercourse.
Flows in excess of any agreed rate will need to be stored on site to the environment Agency's requirements for all events up to the 1 in 100 year plus climate change rate, unless a greater event has been stipulated.
As you may be aware, Anglian Water will consider the adoption of SuDs provided that they meet the criteria outline in our SuDs adoption manual. This can be found on our website at http://www.anglianwater.co.uk/developers/suds.aspx. We will adopt features located in public open space that are designed and constructed, in conjunction with the Local Authority and Lead Local Flood Authority (LLFA), to the criteria within our SuDs adoption manual. Specifically, developers must be able to demonstrate:
1. Effective upstream source control, 2. Effective exceedance design, and 3. Effective maintenance schedule demonstrating than the assets can be maintained both now and in the future with adequate access.
If you wish to look at the adoption of any SuDs then an expression of interest form can be found on our website at: http://www.anglianwater.co.uk/developers/suds.aspx
Trade Effluent We note that you do not have any trade effluent requirements. Should this be required in the future you will need our written formal consent. This is in accordance with Section 118 of the Water Industry Act (1991).
Used Water Budget Costs It has been assumed that the onsite used water network will be provided under a section 104 Water Industry Act application. It is recommended that you also budget for both infrastructure charges and connection costs. The 2016/17 charges are:
Infrastructure Charge £354.00 per connection

Water pressure and flow rate: The water pressure and consistency that we must meet for your site is laid out in the Water Industry Act (1991). This states that we must supply a flow rate of 9 litres per second at a pressure of 10 metres of head to the external stop tap. If your water pressure requirements exceed this then you will need to provide and maintain any booster requirements to the development site.
Self Lay of Water Mains: A list of accredited Self Lay Organisations can be found at www.lloydsregister.co.uk/schemes/WIRS/providers-list.aspx.
Used Water Water Industry Act – Key Used Water Sections: • Section 98: This provides you with the right to requisition a new public sewer. The new public sewer can be constructed by Anglian Water on your behalf. Alternatively, you can construct the sewer yourself under section 30 of the Anglian Water Authority Act 1977.
Pre-Planning Report Thursday, 08 December 2016 • Section 102: This provides you with the right to have an existing sewerage asset vested by us. It is your responsibility to bring the infrastructure to an adoptable condition ahead of the asset being vested. • Section 104: This provides you with the right to have a design technically vetted and an agreement reached that will see us adopt your assets following their satisfactory construction and connection to the public sewer. • Section 106: This provides you with the right to have your constructed sewer connected to the public sewer. • Section 185: This provides you with the right to have a public sewerage asset diverted.
Details on how to make a formal application for a new sewer, new connection or diversion are available on our website at www.anglianwater.co.uk/developers or via our Developer Services team on 08457 60 66 087.
Sustainable Drainage Systems: Many existing urban drainage systems can cause problems of flooding, pollution or damage to the environment and are not resilient to climate change in the long term. Therefore our preferred method of surface water disposal is through the use of Sustainable Drainage Systems (SuDS). SuDS are a range of techniques that aim to mimic the way surface water drains in natural systems within urban areas. For more information on SuDS, please visit our website at http://www.anglianwater.co.uk/developers/suds.aspx We also recommend that you contact the Local Authority and Lead Local Flood Authority (LLFA) for the area to discuss your application.
Private Sewer Transfers: Sewers and lateral drains connected to the public sewer on the 1 July 2011 transferred into Water Company ownership on the 1 October 2011. This follows the implementation of the Floods and Water Management Act (FWMA). This included sewers and lateral drains that were subject to an existing Section 104 Adoption Agreement and those that were not. There were exemptions and the main non- transferable assets were as follows:
• Surface water sewers and lateral drains that did not discharge to the public sewer, e.g. those that discharged to a watercourse. • Foul sewers and lateral drains that discharged to a privately owned sewage treatment/collection facility. • Pumping stations and rising mains will transfer between 1 October 2011 and 1 October 2016.
The implementation of Section 42 of the FWMA will ensure that future private sewers will not be created. It is anticipated that all new sewer applications will need to have an approved section 104 application ahead of a section 106 connection.
Encroachment: Anglian Water operates a risk based approach to development encroaching close to our used water infrastructure. We assess the issue of encroachment if you are
Pre-Planning Report Thursday, 08 December 2016 planning to build within 400 metres of a water recycling centre or, within 15 metres to 100 metres of a pumping station. We have more information available on our website at http://anglianwater.co.uk/developers/encroachment.aspx
Locating our assets: Maps detailing the location of our water and used water infrastructure including both underground assets and above ground assets such as pumping stations and recycling centres are available from www.digdat.co.uk. All requests from members of the public or non-statutory bodies for maps showing the location of our assets will be subject to an appropriate administrative charge.

Land off Newport, Pagnell Road, Development Impact Assessment 1. Summary
This report has been undertaken in response to an enquiry from M-EC Consulting Development Engineers to determine the impact of flows from the site at Newport Pagnell Road, Great Billing on the performance of the existing foul sewer network. It should be read in conjunction with the pre-planning report dated 15th March 2015, for the same site comprising 200 properties, which indicated that if all flows were connected to the public foul sewer system at MH5901, that is is likely to have a detrimental effect on the existing sewerage network. Further hydraulic modelling has been requested to provide a solution for draining all the foul flows from the proposed development to MH5901. The analysis has been performed on the foul system only. There has been no consideration of the surface water flows as this is not within the scope of the study. The additional foul flows from the development site comprising 450 dwellings were modelled connecting to modelled manhole reference no. MHSP77565901 (NGR SP7754456923) located on Newport Pagnell Road. The study concludes that the development will cause detriment to the capacity of the sewer system and will result in increased flood risk downstream of the proposed connection point. In order to mitigate the impact of the proposed development upon the network the following option is recommended: Provide offline storage of capacity 40m3 in the green area near Wooldale Road.
The predicted total capital scheme cost for the required mitigation solution is £269,750 with an indicative developer contribution of £29,976. The predicted total 3 embodied carbon 38TCO2e. The predicted water footprint is 28m H2Oe. The topography of the site indicates that a gravity regime is required. Due to the proximity of the site to the connection point it is assumed that the developer will provide the necessary infrastructure to convey flows from the site to the network. The contents of this report and costs supplied are an estimate based on a solution generated by a desktop hydraulic model. These are estimated figures which are not to be relied upon without further detailed investigations.
Land off Newport, Pagnell Road, Development Impact Assessment Page 1 of 13 2. Hydraulic Modelling and Solutions
The proposed development site is located off Newport Pagnell Road on the eastern edge of Wooton (see Figure 1). Foul flows from the site drain to Great Billing Water Recycling Centre (WRC) located to the west of the town. The proposed development comprises 450 dwellings only. To enable the analysis to be performed the existing hydraulic model for Great Billing was used. This was updated to include recent changes to the system, based on information provided by the local operations team.
Figure 1: Showing the expected downstream trace from the development site to the WRC
Proposed connection point The proposed connection point for the development is manhole reference number SP77569501, (NGR SP7754456923) located just off Newport Pagnell Road (see Figure 2). The diameter of the sewer to which the proposed development will connect is 150mm. A review of the site topography indicates that a gravity connection is feasible.
Land off Newport, Pagnell Road, Development Impact Assessment Page 2 of 13 Proposed connection point MH SP77565901
Figure 2: Showing the proposed connection point
Hydraulic modelling The hydraulic model was run to determine the existing sewer performance during a 1 in 20 year critical duration storm. The model was then re-run with the estimated flows from the site connecting to manhole SP77565901 via a gravity connection. The model predicts a significant increase in flooding at six manholes of which two are located directly downstream of the proposed development (see Figure 3). Surcharging is also predicted in the network due to the additional flows from the development (see Figure 4). There are also increases in spill volume at Abington combined sewer overflow (CSO), Northampton Bedford Road CSO, Northampton Bedford Road sewer overflow (SSO) (see Figure 5).

Figure 5: Showing overflow locations where an increase in spill volume is predicted to occur The level of detriment predicted due to the additional flows from the development means that a mitigation solution will be required to allow the site to connect to the existing sewerage system.
Land off Newport, Pagnell Road, Development Impact Assessment Page 5 of 13 Mitigation Solution Mitigation solutions are designed to prevent detriment to the existing sewerage network performance during a 1 in 30 year critical duration storm event. The proposed mitigation solution comprises: 1. 40m3 of of-line storage in the green area near Wooldale Road.
Figure 6: Showing the location of the proposed mitigation solution This is a feasible solution for planning application purposes. A detailed design would be required to investigate the solution further. Alternative Solutions At detailed design stage alternative solutions may also be considered: o A sewer upsize option may be possible. This would require the upsize of 812m sewer from 600mm to 900mm at a point downstream of the development site. This option has not been taken further at this stage due to the expected disruption and associated cost. Existing Sewer Capacity The modelling shows that surcharging occurs as new properties are added to the network. As per the pre-planning response, up to 50 properties could be connected before the off-site reinforcement solution was in place.
Land off Newport, Pagnell Road, Development Impact Assessment Page 6 of 13 3. Summary of Cost Estimates
The estimated cost for the proposed off-site reinforcement solution is £269,750. The Water Industry Act enables the developer to benefit from any wastewater revenue generated from the houses they have built. In simplified terms, future revenue from the new dwellings is offset from the developer’s contribution. Instead of paying the full contribution the developer pays the difference between their capital contribution and the future revenue. This is calculated on an annual basis for 12 years (see Appendix 2). The developer has the option of paying this annually (relevant deficit) or upfront as a commuted sum (discounted aggregate deficit).
The indicative cost chargeable to the developer for the required mitigation following the offsetting of expected future revenue is predicted to be £29,976. This future revenue has been calculated based on constructing 50 residential dwellings in year 1 and then 100 dwellings per year thereafter. (see Table 1).

It has been assumed that the developer will provide the infrastructure to convey the flows from the site to the connection point. Consequently, this report does not include any costs for the conveyance of flows. The contents of this report and costs supplied are an estimate based on a solution generated by a desktop hydraulic model. These are estimated figures which are not to be relied upon without further detailed investigations.

Assumed flows from the site at Land off Newport, Pagnell Road have been modelled connecting via gravity to the existing foul drainage system to manhole reference no. SP77565901 and detriment to the existing performance has been predicted. To mitigate against this a feasible foul drainage solution is proposed comprising: 1. Provide offline storage of capacity 40m3 in the green area near the Wooldale Road.
Embodied carbon cost
The embodied carbon predicted in this solution is 38TCO2e (see Table 2). Water footprinting
3 The predicted water footprint for this solution is 28m H2O (see Appendix 3). Conveyance of flows It is assumed that the developer will provide the infrastructure to convey flows to the network.

This is a feasible solution for planning application purposes.
Land off Newport, Pagnell Road, Development Impact Assessment Page 8 of 13 5. Next steps
To proceed with this option, it is recommended that an application is made under Section 98 of the Water Industry Act. This will enable a detailed design and robust cost to be generated and the scheme to be delivered. An application form is available on our web site at www.anglianwater.co.uk/developers/sewer-connection/new- sewer.aspx. Underwriting detailed design Detailed design commences on receipt of an underwriting agreement. Payment is only sought from the developer if it chooses to abort the work. Otherwise, it is incorporated into the total scheme cost. For this scheme, an underwriting of £20,000 will provide detailed options from which a preferred option may be chosen. A cumulative underwriting of £42,000 will take the preferred option to a level of design where it is ready for construction. Typically this takes an estimated 44-52 weeks but may increase depending on the complexity of the scheme. At this stage a robust cost for the scheme can be provided. Further work required for a section 104 or section 106 application Please note, it would be deemed premature by Anglian Water to submit a Section 106 or Section 104 application under the Water Industry Act 1991 to Developer Services prior to a Legal Agreement being signed under Section 98 of the same act ensuring the provision of the necessary upgrade works as identified within this report.

Land off Newport, Pagnell Road, Development Impact Assessment Page 10 of 13 APPENDIX 2. - Calculation of relevant deficit and discounted aggregate deficit.
The financial propositions that are available in the Water Industry Act (WIA) are: Relevant Deficit (WIA section 100) Discounted Aggregate Deficit (WIA section 100A) Under each option, the cost of installing the required infrastructure is calculated. This cost is then translated into a notional ‘loan’ to fund the installation. The revenue is then offset over a period of 12 years, taking into account inflation. If the cost of financing the loan exceeds the revenue in any year, then this deficit is charged to the developer.
A2.1 Relevant Deficit
This option takes the actual cost of providing the infrastructure as the basis for a notional loan. On an annual basis (for 12 years) the actual revenue we receive in respect of the infrastructure is then offset against the cost of the annual repayments of the notional loan. The deficit is paid annually by the developer for a period of up to 12 years. This is shown in Figure A2.1 below. The developer will need to provide an undertaking to pay the deficit each year and also provide security for the estimated annual deficits either in the form of a cash deposit or a bond.
Relevant Deficit

Land off Newport, Pagnell Road, Development Impact Assessment Page 11 of 13 A2.2 Discounted Aggregate Deficit
This follows the same principles as the Relevant Deficit payment method, except that the deficit will be paid as a single payment and the revenue is estimated from the build rate rather than from the actual revenue. The yearly relevant deficit is calculated across the 12 years and a discount factor is applied to bring the deficit to its net present value. The deficit is normally reconciled against the security (see below) within 12 months of completing the infrastructure and is payable as a single commuted sum. This can be seen in Figure A2.2. The developer will need to provide an undertaking to pay the full deficit after reconciliation and a security amount for the estimated deficit either in the form of a cash deposit or a bond. The deficit itself is payable on completion of the water mains following the reconciliation.

Land off Newport, Pagnell Road, Development Impact Assessment Page 12 of 13 APPENDIX 3. – Embodied carbon and water footprinting
Carbon footprint
In 2006 Anglian Water recognised the impacts of changing climate as one of the most significant challenges facing the organisation. In response we have developed and implemented a strategy of measure, manage and reduce our carbon emissions. We have set ourselves goals to halve our overall greenhouse emissions by 2035 (from 2010 levels).
Water footprinting
Water is our most precious resource and at present we do not fully understand how sustainable each litre of water we supply to our customers is over our full supply chain. In response, we are implementing a strategy of ‘water footprinting’. Primarily water footprinting assesses the impact of human activity on the water environment. The process measures the volumes and scarcity of freshwater consumption including geographical and temporal components in producing a product or service. This is followed by an assessment defining actions required to achieve sustainable and equitable water use especially in water scarcity ‘hot spots’.
