Many garages, petrol stations and supermarkets have car washing facilities such as jet washers and drive through car wash machines. The liquid streams, containing detergents, oils and grease, resulting from the washed vehicles can be damaging to the environment therefore vehicle wash interceptors are required to prevent oil and grease entering watercourses and sewerage systems.
When the outflow of water and oil from a wash bay enters the wash bay interceptor the oil becomes emulsified, due to detergents and hot water. Because the water is no longer free flowing, a standard wash bay interceptor will not separate the oil which would simply pass through the chambers.
The Morclean oil removal system uses a dosing system to split the emulsions so that the oil can be removed by a filter, therefore limiting the outflow of oils to the mains foul drain. Where the levels and falls are insufficient to outflow to the mains foul drain under gravity, then a Morclean Pumping Chamber can be used.
All our GRP chambers can be made in various pipe sizes, outlet and inlet sizes and invert levels. The chambers are redirected to a 600mm access chamber that can be neatly concealed under a standard Manyway cover and lid.*
The oil filter can even be housed in the third or fourth chamber of the existing interceptor (or standard interceptor) or separate pumping chamber. This all depends on the site specific conditions, every aspect of which we will take into account. The outflow of water can fall to mains foul either via gravity or a Morclean Pumping Chamber can be used to outflow the water along an incline.
*Manway Covers and lids are an added extra as pumping stations are also all available above ground.
The above requires manhole cover(s) and lid(s) (not included). Due to the weights involved covers and lids are expensive to transport and often cost more to ship than they are worth so we advise you source your own. You can purchase covers and lids from most builders merchants and below is a guide to assist you choosing the best type for the duty.

EA and SEPA Pollution Prevention Guidelines (PPG)
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 doesnít 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 isnít 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:
