An interceptor removes grease and oil, as well as solidmaterial such as dirt, hair, glass, sand or silt from wastewater before it enters thesewer system. To work properly they should be cleaned regularly and the wasteremoved appropriately. In a garage, this waste is likely to be hazardous.i don’t throw hazardous materials down the sink or toilet - this is illegal andvery polluting. In areas where there is no wastewater treatment this is particularlydangerous to the local supply of drinking water.i Larger generators of wastewater (usually those that wash cars regularly or have acarwash) should have a trade effluent licence. These are issued by your localauthority and will have specific requirements for your particular site.i Make sure everyone in your garage is aware of the potential problems waterpollution can cause, in both legal and local terms.WATER - WHAT YOU MUST DO!are you doiNg iT?If you have a large car wash you probably need a trade discharge licence.Contact your local authority about this.WATER- CARWASHThe use of power or high-pressure washers is common in Irish garageswith the water usually draining to storm water sewers or in many rural sites,directly to surface or ground water. The detergents used and the dirt fromwashing can pollute receiving waters. If you are using these you may needa Trade Effluent License so contact your local authority for more information.iiiiifor power washers and self-service car washes the following should beconsidered:Choose hand-held spray wands and foamy brushes that use no more than 1 litresper minute. (Water Savings: 0% - 0%)Make sure each spray wand, foamy brush, or similar system has a shutoff triggervalve so that the water will not run while the system is not being used.Replace spray nozzles regularly and check for leaks. Repair the leaks as soon as theyoccur.Replace brass or plastic nozzles (which tend to erode more quickly) with stainlesssteel nozzles.Beware of compressed air leaks - car washes are often away from the mainoperation of a garage and air leaks can be overlooked.
