The treatment plant you choose should be around 95% e cient thus allowing long intervals before de-sludge is required. The waste water must be cleaned to a standard meeting the usual discharge level requirement, you must apply for either an exemption certificate or permit, before making a discharge we can assist with this and advise on the method of discharge, be it a ditch, stream, watercourse or soakaway.
As the system breaks down and aerates the solids, the introduction of non-degradable items such as wipes, sanitary products etc. should be avoided at all times in any treatment plant, this will clog up the system and increase the need to empty the unit, follow this instruction and typical emptying will be around 3-5 years, it is also recommended no medicines, or harsh chemicals enter the unit, try to stick to Eco brands and stagger washing throughout the week.
