Drain Installations in London

Project managing the installation of an additional drain or complete new drainage system in the United Kingdom requires strict adherence to Building Regulations Approved Document H1 to H6 for drainage and waste disposal otherwise you will fall foul of the legal requirements upon you and your building company.

You can save save time, money and avoid disruption to your building project by instructing a London drainage contractor that is proven to be competent in the installation of drainage systems in line with approved documents H1 foul water drainage, H2 waste water treatment systems and cesspools, H3 rainwater drainage, H4 building over sewers, H5 separate systems of drainage and H6 solid waste storage.

When adding a new drain we survey the existing system using a drain camera and compile a detailed report which assesses if it is suitable for a new connection and additional waste water by taking into account its duty, depth, volume capacity and condition then engage in consultation with your surveyor and or building inspector to ensure the project from planning to sign off is seamless.

Drain Misconnections in London Areas

If soil stack pipes or grey waste water gullies that serve toilets, showers, washing machines or dishwashers are misconnected to a surface water drainage system this allows untreated sewerage and waste water containing oils and chemicals to run into rivers, streams and other fresh water courses. A drainage misconnection is a pollution factor that impacts the environment, wildlife and natural eco system. A misconnected drain is also when a rain water pipe or surface water gully has been inadvertently connected to a foul water drainage system and can result in flooding by overwhelming the system in periods of heavy rain fall and surface water run off.

Misconnections are illegal under section 109 of the water industry ACT 1991 therefore If you are planning a residential property extension or a commercial premises refurbishment that requires add on drain installations it is recommended that you instruct a certified CCTV drain survey contractor in your area to assess and map the drainage system or systems to identify the correct system for your new connection. Some properties will have separate foul and surface water systems whilst some properties may have a combined drainage system which allows the discharging of both foul and surface water but it is very important to confirm this at the planning stage of your project which you can sometimes also do by confirming the duty of the public sewers which serve the properties in your location by requesting an asset location search from Thames Water.

Pro-Drain installers can quickly fix drainage system misconnections in London. If you have been notified by Thames Water that you have a foul water drain discharging into a surface water drainage system we can quickly correct this for you. We also undertake necessary drainage surveying required to assess the duty, ownership and condition of drainage systems.
