This document aims to help self-lay organisations in designing their own schemes, by making clear our requirements for new pipework and other assets. These will become part of our supply network, often for decades to come. We therefore need to ensure they are fit for purpose and comply with a range of guidelines, explained over the following pages.

Most of the standards we outline below are our own, often based on guidance from the National Joint Utilities Group (NJUG). They also include guidance based on UK legislation. Please note that failure to meet these standards could delay or prevent your approval.

This document should be used in conjunction with our self-lay policy and company-specific addendum to the WRc Code of Practice for the Self-Laying of Water Mains and Services (England and Wales), 2nd edition, 2009. This can be found in the ‘Building and developing’ section of our website, under ‘Self-lay water supply’.

We require developers to make an initial enquiry or a capacity check with us in advance of an application for a new connection to our network. This will help ensure there is sufficient capacity in our water network when it is needed and indicate the potential costs of providing any new capacity or using any previously installed capacity needed for the development.

Completing a capacity check at planning stage will help avoid delays in supplying the site at construction stage.

For further information, including details on pre-development enquiries, please refer to our website or contact us using the details below.

Introduction

Contact detailsThames Water Developer Services2nd Floor WestClearwater Court,Vastern Road,Reading,RG1 8DB

Tel: 0800 009 3921www.thameswater.co.uk Thames Water Utilities Ltd Registered in England and Wales No. 2366661, Registered Office.

All works should comply with BS EN 850 Water Supply, Requirements for Systems and Components Outside Buildings. Design and construction should comply with the current edition of the Civil Engineering Specification for the Water Industry (CESWI). It should also be in line with the National Joint Utilities Group (NJUG) guidelines, Volume 2, available at www.njug.org.uk.

1.1 Self-lay policy – General informationPlease refer to our Self-Lay Policy and Addendum to the WRc Code of Practice, which can be found in the ‘Building and developing’ section of our website, on the page headed ‘Self-lay: How to apply’.

1.2 Point of connection We will determine the point of connection to the existing distribution network. System reinforcement might be required prior to connection depending upon capacity. We will not make the final connection of the self-laid main to the water distribution system until you have provided satisfactory disinfection, pressure test and water sample results.

1.3 Routing positioning and locationWhen deciding on the optimum pipeline route, we will take into account the following factors:

• Hydraulic gradient• Terrain and subterranean conditions• Hazards and obstacles, including

contaminated ground• Existing and future land use• Permanent access• Transport facilities• Utility services

• Agricultural practice• Environmental impact• Industrial and commercial development• County structure plans

On distribution mains, please ensure dead ends do not serve more than 100 properties. They should have a maximum design velocity of 0.6m/s.

Please ensure that all water mains with unrestrained joints have thrust restraint at bends, junctions, line valves and changes in diameter.

Wherever practicable, ensure that distribution mains are located in the footway/verge, in accordance with the NJUG guidelines Volume 1. The pipeline and associated fittings need to allow adequate access from public highways for the equipment and materials necessary to carry out valve operations, inspections, maintenance and emergency repairs, and decommissioning. Service stripsA service strip is a dedicated trench for utilities services in public or private land. The main should be within a service strip provided by the customer. The service strip must be at least 1.8 metres wide – if this width cannot be achieved, we will lay the main in a position which we deem most suitable. Service trenches should be provided within footpaths, roads, or verges.

We sometimes find that the developer provides a service trench in a strip of land situated within the gardens of the new dwellings. Please ensure you avoid this and find a more suitable alternative. Buildings (existing or proposed) should not be situated immediately beside a service strip, as this impedes work to lay the main as well as future maintenance activities.

1. Design principles

http://www.thameswater.co.uk/developers/686.htm

Adoptable vergesAn adoptable verge is a strip of ‘unmade ground’ running parallel to the carriageway/footpath. If a main is to be laid within a verge, the finished surface should not be planted with trees and shrubs.

Third party landThird party land is privately-owned land which requires entry in order to provide a development with water and is not owned by either the local council/highway authority or the applicant. In order to provide a development site with water, it may be necessary to cross land which is under several different ownerships.

You should only consider laying mains within ‘third party land’ as a last resort and should seek an alternative route wherever possible. The general concept of laying mains in private roads is acceptable.

1.4 Depth of mainsDistribution mains should be laid in trenches where there will be a minimum cover of 0.9 metres and maximum cover of 1.2 metres – this is to give any service connection adequate protection from frost (a minimum cover of 750mm).

Every mains design drawing should carry the ‘preferred layout’ template in accordance with NJUG guidelines, which indicates the depth of a water main in conjunction other utilities apparatus. When deciding on the depth of a main, please ensure you consider the weight and frequency of vehicles likely to travel over it.

Please tell us if any new main has to be laid at a reduced depth due to underground obstructions, bridge decking restrictions or any other type of unavoidable obstruction. It is also your responsibility to include the depth of cover of the new main and the depth of cover at the point of connection to the existing main / mains on the ‘as-laid’ drawing.

1.5 Pipe materials, sizing and pressure rating

Choice of materialAll pipes must be marked with the Standard Dimension Ratio. High-performance polyethylene (HPPE) is our preferred material for new mains and

should always be used unless the Soil Analysis Report determines otherwise.

HPPE is identified blue as per NJUG guidelines Volume 2. HPPE pipe is referred to by its external diameter, and should be designed in 90mm, 125mm, 180mm and 250mm, and 355mm mains.

HPPE has a pressure rating of 16 bar and is joined together by ‘butt fusion’ and ‘electro fusion’. Marker tape should be used within the trench in order to provide a means of tracing HPPE pipe. Medium-density polyethylene (MDPE) should be used for should be used for service connection pipes up to and including 63mm.

Neither HPPE mains not MDPE service connections are to be laid in sites which have been deemed contaminated by us following analysis of the customer’s Soil Analysis Report. Wherever contamination is identified, new mains and service connections must be in plastic barrier pipe (up to and including 63mm). Please note that plastic is now our preferred material for barrier pipe.

Ferrous pipe is referred to by its internal diameter and is designed in 100mm, 150mm, 200mm and 300mm sizes. 1.6 JointingButt fusion is our preferred method of jointing plastic pipe, which must be of identical diameter and pressure ratings. Butt fusion can only be carried out outside the trench, and electro fused couplings should therefore be employed where butt fusion is not practicable, i.e. when making the connection from a length of main to a fitting. Electro fusion couplings must be installed wherever the pipe cannot be ‘butt fused’, i.e. at bends, ends, directional changes, and where two sections of main are required to be joined within the trench. They must be HPPE (PE100) and can be black or blue in colour. All electro fusion fittings must incorporate fusion indicators.

Gaskets are rubber rings, which provide a watertight seal within the joint. They provide a flexible joint and are installed within the socket end of the pipe in order to prevent the pipe separating. Gaskets should not be fitted at critical points such as bends, ends or directional changes, which require the installation of anchor gaskets.

1.7 Mains in new development areasWhere the point of entry is less than 10 metres from a water main, service connections can be installed.

Service pipe layout where supply pipe exit is less than 10 metres from a water main

Where points of entry are further than 10 metres from a water main, a new main can be installed.

1.11 Mains in retail parks and commercial areasWherever possible new mains should be located in a road built to an adoptable standard. In retail parks, commercial and industrial areas, it may not always be clear which areas are streets, and there is a particular risk that layouts of buildings, car parks and access roads may be changed without consulting us.

In such areas, we may require an easement to be granted, in order to protect our assets. New water mains should be co-coordinated with other services such as gas, electricity and telecoms, and laid in accordance with Volume 2 of the NJUG guidelines.

1.12 Unadopted roads

An adoptable standard footpath is a walkway that is constructed to the standards demanded by a local council or highway authority. The footpath is normally of a minimum width of 1.8 metres. SLOs should only consider laying mains in a footpath narrower than 1.8 metres if it is not used by any other utilities services. If the main is not laid within this footpath, then it should be positioned in the road about one metre from the kerb line.

An adoptable standard road is a carriageway road that is constructed to the standards demanded by a local council or highway authority. The carriageway is normally of a minimum width of 5.5 metres. If the main is not laid within this carriageway, it should be positioned approximately one metre from the kerb line.

1.13 Gated developmentsIf a private road is ‘gated’, it is good practice to install a valve on the main just outside the gate. This will ensure that we can ‘close in’ the main without affecting other customers.

1.14 Land rightsThe Water Industry Act 1991 allows us to lay pipes in streets and private land, and we usually rely on these powers rather than obtaining formal easements. These rights do not apply when the pipes are laid by an SLO. This requirement for land rights should be assessed at design stage and indicated on the approved layout drawings prior to any acceptance of the scheme by the developer. Please ensure you tell us when any proposed land rights are needed so that all required documentation is in place at the earliest possible stage.

Any ‘as laid’ record must be fully in accordance with the planned position of the main that was shown in any notice before the main is connected to our network.

1.15 Water mains in a streetAn adopted footpath is a public walkway which is maintained by the local council or highway authority. The footpath is normally of a minimum width of 1.8 metres. SLOs should only consider laying mains in a footpath narrower than 1.8 metres if it is not used by

any other utilities. If the main is not laid within this footpath, it should be positioned in the road about one metre from the kerb line.

An adopted road is a carriageway which is maintained by the local council or highway authority. The carriageway is normally of a minimum width of 5.5 metres. If the main is not laid within this carriageway, it should be positioned approximately one metre from the kerb line.

1.16 Water mains not in a street Sections 158, 159 and 168 of the Water Industry Act 1991 give us powers to lay mains in streets and private land without obtaining formal easements.

1.17 Self-lay in land that is not a streetWhen mains are self-laid in private land and intended to be subsequently adopted by us, the rights provided by the Water Industry Act 1991 do not apply to SLOs. In such cases, the developer will need to obtain permission from the land owner to install the pipes and then arrange for a deed of easement in favour of Thames Water to be in place before the new mains can be adopted and connected to our network. Any costs incurred in arranging the permissions and subsequent transfers to Thames Water are to be paid by the developer. Advice on all issues concerning pipes in private land should be sought from us.

2.1 Design guidance pressureOur requirements on network pressures are as follows:

• At all times the pressure within the network must be maintained above 1.5 bar. The design of the replaced network must not result in pressures above 10 bar unless previously agreed with us.

• The design must limit the hydraulic level across the area at peak instantaneous flow, to avoid unacceptable pressure changes throughout the day. Hydraulic gradients need to accommodate areas with significant ground level changes or tall buildings.

Please also note that we may require you to install pressure management systems in areas where the static pressures exceeds 5 bar.

2.2 Design guidance velocity of flowThe velocity of flow should be between 0.4m/s and 0.6m/s under average daily operating conditions, and between 0/6m/s and 1.0m/s under peak daily operating conditions, excluding emergency conditions.

2.3 Design guidance hydraulic gradientAny new pipe or network change should be designed so that the hydraulic gradient is typically in the range of 2 to 4 metres per 1000 metres in the proposed main, and in any existing mains that may be influenced by the proposal. However, if downstream pressure is available in sufficient quantity and its reduction is not a concern to us, then a hydraulic gradient not exceeding 10 metres in 1000 metres can be used.

2.4 Sizing new mains for domestic premisesThe following should be used as a guide to the number of residential properties that can be supplied from a new main. These figures are for new mains calculations only and must not be used for service connections.

When a new development has a mixture of houses and flats, the overall demand of the development should be calculated and the mains sized accordingly.

2.5 Sizing mains for non-domestic and mixed demandsWe must carry out the sizing of mains on schemes for non-residential properties, as these need to be modelled, or may have already been modelled. Under the Water Industry Act 1991, we can refuse to supply premises requiring non-domestic use. However, we always look to accommodate customers’ requirements and refusal is only in extreme cases. You must ensure you match our requirements – for example, regarding storage – before we agree to supply the premises.

2.6 Managing water quality in new mainsPlease avoid dead legs wherever possible. New mains should be designed to ensure that the last service connection point is no more than one metre away from any end washout.

Mains should not be laid and commissioned in anticipation of future development, as this would constitute a dead leg. Tees can be installed for future phasing of a development, providing they have a valve and washout on the outlet.

3.1 Isolating valvesValves are installed to isolate sections of main and to ensure integrity of supply. A valve is installed on every tee outlet for shutting in and identifying the line of the main. The only exception to this rule is where a tee connection includes a valve fitted either side (in-line), in which case there is no gain achieved by the installation of a valve on the outlet branch.

A valve should be installed along a straight length of new main in order to protect more than 50 properties. A valve should be fitted every 500 metres along a straight length of new main, in order to isolate sections of main for future repair and maintenance purposes.

A valve should also be installed on a main immediately on the public side of any gated private access roads. This will ensure that the main can be ‘closed in’ without affecting other customers. Depending on the size and nature of the proposed new development, and the layout of the existing network, it may be necessary to install new valves either side of the tee connection to ensure integrity of supply.

When installing a valve within a verge or soft ground, the chamber should be adequately supported. This is achieved by providing a one-square-metre layer of concrete to 150mm depth around the chamber, which prevents foliage growing over the chamber and damage to the fitting when operating.Valves should comply with BSEN1563, and internal and external protection must be provided by blue fusion-bonded epoxy powder coating. All valves should be right-hand (clockwise) close only.

3.2 Air valvesAir valves are a means of venting air from the network. They should be installed at points where air can accumulate, such as high points along the route of a new main, bridge crossings and where a main is diverted under an obstruction. An air valve should be installed in conjunction with a tee along the line of a main.

When installing an air valve within a verge or soft ground, the chamber should be adequately supported. This is achieved by providing a one-square-metre layer of concrete to 150mm depth around the chamber, which prevents foliage growing over the chamber and damage to the fitting when operating.

3. Valves

Washouts are installed in order to maintain the integrity of the water supply by providing flushing points.

Combinations of isolation valves and washouts must be provided to enable the isolation and flushing of sections of the main. Washouts must be installed:

• To achieve isolation of a maximum of 500 properties

• At road junctions • At all tees • At a maximum distance of 100 metres apart

A washout must be installed at the end of every leg of main, no more than one metre after the last service connection, in order to prevent the build-up of stagnant water in the main. When connecting a new main between two or more existing mains, washouts should always be installed on the outlet branch of the tee connection point with any existing main. This provides adequate facility for any future disinfection / flushing required across the site.

Please ensure you install washouts and a valve every 500 metres along a straight length of new main, so that sections can be disinfected and flushed following any future repair / maintenance activities. A washout must always be installed next to every closed district boundary valve.

When installing a washout within a verge or soft ground, the chamber should be adequately supported. This is achieved by providing a one-square-metre layer of concrete to 150mm depth around the chamber, which prevents foliage growing over the chamber and damage to the fitting when operating.

4. Washouts

5.1 DefinitionsThe communication pipe is the part of the service pipe owned by us and laid in the same street as the main to which it is connected.

The service pipe connects the water main and the premises being supplied.

The supply pipe is the part of the service pipe belonging to the property owner, and laid within the property boundary.

5.2 Conditions for connectionWe will only connect new pipework to our network once these conditions have been met:• We have received payment for the quotation.• A Water Regulations inspection has taken place

confirming the pipework laid is to the correct standard.

• We have received chlorination results and confirmed that they are acceptable for all supplies with an internal diameter of 50mm and greater.

5.3 General requirements for service pipesServices on non-contaminated sites up to and including 63mm must be made of MDPE (PE80). Services on contaminated sites must be made of barrier pipe.

5.4 Service connection arrangementsWhen a new development is being planned, service connections should be designed in conjunction with both new and existing mains to ensure that services are:

• Laid in a position agreed with Thames Water• Generally perpendicular to the main• Not crossing others’ land• A minimum of 25mm diameter blue PE (or barrier

pipe as required), minimum depth 750mm, maximum depth 1350mm

5.5 Standard service connection detailsThe service pipe must be installed up to the property boundary. It should be installed at right angles to the distribution main and follow a straight line to the boundary box wherever possible.

All service pipes and meter inlets and outlets must be installed with a minimum cover of 750mm. You must inform us if this cannot be achieved, or if a customer supply pipe is found to be less than 750mm in depth.

The service pipe and supply pipe must be connected with a service adapter at the property boundary.

Where a service has been laid through a duct, the duct must only be used if it is at the correct depth (750mm), and is in line with the customer supply pipe. When installed, the tapping duct and meter box must be in a straight line.

All customer connections to the network must have a means of isolating the customer supply.

6.2 Internal fit metering for flats or multi occupancy premisesPlease refer to our internal fit metering guidance leaflet.

6.3 Metering standard service connectionsFor further information, please refer to our Self-Lay Policy and Addendum to the WRc Code of Practice.

6.4 Meter specification• All meters are sourced by us at a cost to the

developer or the SLO.• Concentric 15mm meters are used for external fit

in boundary boxes / manifold boxes.• Internal meters are 20mm in line and are supplied

with a fitting kit.

6.5 Meter pits• Boundary boxes are used to install up to six meters

on pipework entering a property at the same location. A 600mm x 450mm pit will be required for installations of up to six meters if a boundary box cannot be used.

• It must be possible to read the meter from the top of the chamber at ground level. It must also be 300mm to 600mm below ground level.

• Boundary box installations must not sit on any other utilities’ pipes or cables, or any drain or duct.

• Boundary boxes must be Class ‘B’ rated and may be used in areas subject to occasional traffic loading.

• An Atplas box must be used for 25mm and 32mm connections.

6.6 Metering non-standard service connectionsService connections greater than 32mm in diameter are classed as non-standard connections. These may be used to supply a number of individually metered premises or a single premises, where fitted with a bulk meter. The arrangements for metering and their locations are likely to be design-specific and dependent on the construction of the building, the layout of the pipe work and the availability of sufficient space to facilitate the meter installation.

7.1 Fire hydrantsFire hydrants are installed for the relevant fire authority for the purpose of firefighting. They are water company assets but are the responsibility of the fire authority. Fire hydrants are installed as a requirement under the Fire Services Act 2004.

A fire hydrant is an identical fitting to a washout, but identifiable by its cover marked ‘FH’. Fire hydrant positions are highlighted on the approved drawings and are subject to approval by the fire authority. Fire hydrants must be installed within the footpath every 180 metres along a straight length of main. No property should be more than 90 metres from a hydrant. The hydrant must be installed to the correct specification as detailed on the mains drawing. Its installation details are subjected to an audit checklist.

Hydrants must be compliant with BS750:1984. All hydrants must have a copper alloy (gunmetal) outlet and an automatic frost valve. Hydrants must be of a fixed jumper design.

When installing a hydrant within a verge or soft ground, the chamber should be adequately supported. This is achieved by providing a one-square-metre layer of concrete to 150mm depth around the chamber, which prevents foliage growing over the chamber and damage to the fitting when operating

Hydrants should be located so that fire and rescue services’ fire hoses do not run across dual carriageways or railways during firefighting. Additional hydrants may be needed to avoid this possibility.

7.2 Statutory dutyWe are responsible for contacting and providing the relevant fire and rescue service with all information needed to assess firefighting requirements. The fire and rescue service should respond to us, detailing their requirements, within 42 calendar days of having been provided with all necessary information. We will

then provide drawings for on-site auditing purposes based on the approved water main design, indicating the location of any required firefighting equipment. We may refuse to connect any new mains where the agreed firefighting equipment has not been installed, or where a fire and rescue service has not been given adequate opportunity to provide their requirements.

7.3 Requirements for firefighting waterThe Local Government Association / Water UK national guidance document on the provision of water for firefighting gives guidelines on flow requirements for firefighting as follows:

The Water Industry Act 1991 requires us to alter or remove any pipe or other apparatus if requested to do so by a developer if the land cannot be developed without the required alteration or removal. This requirement does not apply to any pipe or equipment that is located in a street.

We will require advance payment of the estimated reasonable cost of diverting or abandoning any existing mains or associated equipment. This applies to both self- lay and requisition schemes.

8.1 A development with both a new main and an abandoned mainFor this development it was necessary to install a new main for half of the development and also to abandon and divert an existing main to accommodate the new buildings on farm land.

8.2 Example of a redeveloped site with a diverted/abandoned mainThis is a development where the existing site has been redeveloped. As a result the main in yellow has been abandoned to accommodate new houses that have been built where a road used to be. New mains also had to be installed.

The diagram below sets out the minimum distances that should exist between water mains and certain types of tree. Please ensure you adhere to these distances in order to protect trees from any future maintenance we need to carry out on the main. You should also read the NJUG guidelines Volume 4 for further information.
