ENCLOSURE TABLE KEY

DESK RESEARCH A cross in this column indicates that the response has been determined In-house.

IN VICINITY Utility plant is expected to be within, adjacent to or very close to the search area. It’s recommended to liaise with the utility in advance of any works taking place.

NOT IN VICINITY Utility plant is not expected to be within, adjacent to or very close to the search area. It may be located some distance from the search area.

DISCLAIMER

RELEVANT DOCUMENTS The following documents must be referred to before work commences in the vicinity of existing services: • Health and Safety Booklet HS (GS) 6 Avoidance of Danger from Overhead Electric Lines. • General Safety Measures to Avoid Injury and Damage to Gas Apparatus. • HSE Guidance Note HS (G) 47 Avoiding Danger from Underground Services. • National Joint Utilities Group (NJUG) Publications Vol. 1. • CDM Regulations 2007 (Regulation 34 – Energy Distribution Installations). • Electricity at Work Regulations 1989.

BASIC RISK ASSUMPTION FOR ALL SERVICES When dealing with existing services the following assumptions must always be accepted: • All existing buildings have gas, water electric and telecoms supplies to them until proven otherwise. • Any supply to an existing building, no matter how old the building is or how deteriorated the supply may appear, is taken to be ‘live’ until proven otherwise. • All open land, vacant lots and derelict sites are deemed to have services beneath them until proven otherwise. • The only acceptable proof that a service is ‘dead’ and can be removed is written confirmation from the owner of the service. • The quality and accuracy of information provided by utilities about their existing plant is indicative and no warranty is made as to its accuracy. Therefore, any utility record plans and/or marked up drawings provided by each utility must only be used as a guide and the actual location of plant should be verified by CAT scan or trial holes before construction works commence.

Please note not all service connections are shown on the utility record plans.

PLANT FOUND WITHIN SITE BOUNDARIES Where utility plant is found within the site boundary, it is recommended for the client to check for legal easements or wayleaves.

Diversions of plant within site boundaries can be expensive and time consuming to relocate. Further investigation of costs and timescales are recommended. Please ask PES for further details.

GUIDANCE

This flow diagram is intended to help give an understanding of the process from referring to plans on-site through to the start of excavation.

For example, could services be non-metallic pipes? Please refer to HS (G) 47 text for further information. † In particular; visual evidence. Ensure that the presence of services, which may be unmarked on plans or for which no plans are available, has been considered, for example service connections. ** If there is visual evidence of services, but owners cannot be traced, despite all reasonable attempts to do so, any excavation could proceed but using hand-dug trial holes and proceeding with great care.

Dear Sir / Madam

An Asset Location Search is recommended when undertaking a site development.It is essential to obtain information on the size and location of clean water and sewerage assets to safeguard against expensive damage and allow cost-effective service design.

The following records were searched in compiling this report: - the map of public sewers & the map of waterworks. Thames Water Utilities Ltd (TWUL) holds all of these.

This searchprovides maps showing the position, size of Thames Water assets close to the proposed development and also manhole cover and invert levels, where available.

Please note that none of the charges made for this report relate to the provision of Ordnance Survey mapping information. The replies contained in this letter are given following inspection of the public service records available to this company. No responsibility can be accepted for any error or omission in the replies.

You should be aware that the information contained on these plans is current only on the day that the plans are issued. The plans should only be used for the duration of the work that is being carried out at the present time. Under no circumstances should this data be copied or transmitted to parties other than those for whom the current work is being carried out.

Thames Water do update these service plans on a regular basis and failure to observe the above conditions could lead to damage arising to new or diverted services at a later date.

Waste Water Services

Please provide a copy extract from the public sewer map.

Enclosed is a map showing the approximate lines of our sewers. Our plans do not show sewer connections from individual properties or any sewers not owned by Thames Water unless specifically annotated otherwise. Records such as "private" pipework are in some cases available from the Building Control Department of the relevant Local Authority.

Where the Local Authority does not hold such plans it might be advisable to consult the property deeds for the site or contact neighbouring landowners.

This report relates only to sewerage apparatus of Thames Water Utilities Ltd, it does not disclose details of cables and or communications equipment that may be running through or around such apparatus.

The sewer level information contained in this response represents all of the level data available in our existing records. Should you require any further Information, please refer to the relevant section within the 'Further Contacts' page found later in this document.

For your guidance: • The Company is not generally responsible for rivers, watercourses, ponds, culverts or highway drains. If any of these are shown on the copy extract they are shown for information only. • Any private sewers or lateral drains which are indicated on the extract of the public sewer map as being subject to an agreement under Section 104 of the Water Industry Act 1991 are not an ‘as constructed’ record. It is recommended these details be checked with the developer.

Clean Water Services

Please provide a copy extract from the public water main map.

With regard to the fresh water supply, this site falls within the boundary of another water company. For more information, please redirect your enquiry to the following address:
