Tanks Direct provide a range of Klargester and Clearwater Cesspools from 18,000 litres to over 80,000 litres. Cesspools or cesspits are simply holding tanks for untreated sewage. Unlike septic tanks there is very little treatment taking place and they do not drain to a soakaway. Consequently they need emptying by tanker. A cesspit would be installed as a temporary solution, where there is no mains drainage or a permanent fixture when large quantities are needed to be stored and cannot be treated onsite due to unsuitable ground conditions. Examples would also include campsites to handle chemical toilet waste, which would negate the treatment processes that take place in a septic tank or sewage treatment plant.
