Thames Water Public Sewer Build-Over Agreements
If you are constructing an extension or new building within 3 metres of a public sewer or lateral drain shared with neighbours, Thames Water requires a Build-Over Agreement before work begins.
- A pre- and post-construction CCTV drain survey is mandatory to prove pipe integrity.
- Pipes under extensions must be protected against structural load settlement.
- No inspection chambers or manholes can be built inside a habitable space unless special sealed covers are fitted.
Building Regulations Part H (Drainage & Waste Disposal)
Approved Document H sets out strict rules for foul water drainage, surface water discharge, and soakaway installations in Buckinghamshire and surrounding councils.
- Foul Water: Must discharge into a public sewer where possible, or a properly sized soakaway / treatment system.
- Surface Water (SuDS): Rainwater must not be allowed to overload foul sewers; sustainable drainage systems and rainwater soakaways must be used.
- Local Soil Types: Heavy clay soil common in Iver and South Bucks requires percolation testing before soakaway installation.

Restaurants, pubs, cafes, and commercial kitchens across South Bucks and West London are legally required under the Water Industry Act 1991 to prevent fats, oils, and grease (FOG) from entering the public sewerage network.

- Regular preventative cleaning prevents severe blockages and heavy local water authority fines.

Local Regulations & Guidance FAQ
Do I need planning permission to replace or repair my garden drain?
Generally, repair or replacement of existing domestic drains on private land falls under Permitted Development and does not require planning permission. However, if you are connecting to a public sewer or altering surface water discharge onto public highways, local council approval and water board notice (Thames Water) may be required.
What is a Thames Water Build-Over Agreement and do I need one?
If you are building an extension, conservatory, or garage within 3 metres of a public sewer or lateral drain that serves neighbouring properties, you must obtain a Build-Over Agreement from Thames Water. A CCTV survey is required before and after construction to prove the drain has not been damaged.
Why does local Buckinghamshire clay soil affect soakaways?
Heavy clay soil common across South Bucks has poor water infiltration rates compared to sandy soils. Building Regulations Part H require a soil percolation test before installing a surface water soakaway to ensure rainwater can drain away safely without flooding your property or neighbours.
Are commercial kitchens required by law to install grease traps?
Yes. Under Section 111 of the Water Industry Act 1991, it is an offence to discharge fats, oils, and grease into public sewers. Commercial kitchens in Iver, Slough, and West London must install suitable grease traps or interceptors and maintain clean discharge records for Environmental Health inspection.
