Overground Water Storage Tanks

The range of overground water storage tanks are ideal when groundworks are either impractical or prohibited, and can also be used for temporary installations. Available in various sizes and capacities the standard models range from 2000 to 20,000 Ltrs in capacity.

Unlike traditional circular water tanks the design allows us to also produce above ground water tanks with a combined interceptor, or, where a temporary site is relocated the tanks can be subsequently installed below ground.

Manufactured from durable GRP the above ground tanks are often used in conjunction with a vehicle wash or water recycling system for storage of overflow or for the subsequent disposal of contaminated water.

The overground tank access chambers provide easy access for emptying and cleaning.

The EA and SEPA Pollution Prevention Guidelines (PPG) which are jointly produced by the Environment Agency for England and Wales, the Scottish Environment Protection Agency, and the Environment and Heritage Service for Northern Ireland (Ref PPG3 / PPG13 / PPG4 / PPG 14) suggest that Class 2 wash bay silt traps and interceptors should be connected only to a mains foul drain, and Class 1 separators to surface drain.

The above assumes you have the consent to connect any outflow to a suitable drain as per the appropriate PPG Guideline. While we always endeavour to provide best advice and accurate information, it the responsibility of the client and/or landowner to comply with the law. Following any guideline doesn’t remove your responsibility to comply with the law and prevent pollution from your activities. Causing or allowing pollution is a criminal offence; compliance with any guidance isn’t a defence. You should make sure that the references to other sources of guidance are still current.

3. Requirements for all vehicle washing and cleaning activities

Activities that produce run-off from the vehicle onto the ground and use cleaning and valeting products should be carried out in areas that are clearly marked and isolated from surface water drainage systems, unmade ground and porous surfaces. These areas are called designated washing bays.

A designated washing bay should be designed so that run-off is:

  • isolated using channels, gullies, gradient (fall on the surface) and kerbs
  • directed to a silt trap or settlement tank to remove larger particles of silt and sediment
  • either collected in a sealed system for reuse, discharged to the public foul sewer with prior permission
  • of the local sewer provider or collected in a sealed system for authorised disposal

You should also:

  • have procedures for everyone, including contractors, that cover where and how vehicle washing and cleaning should be carried out and what to do in a spillage emergency
  • provide notices for designated washing bays saying what they’re for and that washing and cleaning should only be carried out in the bay
  • consider whether a fence or barrier is required to prevent spray or wind drift out of the designated area
  • have procedures and equipment which minimises water use and solid waste production
