How They Work
A Cesspool tank is a sealed, watertight underground tank. It is used purely as a holding tank without an outlet and has no intent to treat or discharge the sewage. A Cesspool tank will usually be discreetly buried underground with a single manhole cover for access.
Cesspool tanks are installed in areas without mains sewerage that are unable to have a septic tank / treatment plant because the ground conditions don’t soakaway, there is no room for a soakaway or it is too far away from a water source to outlet a treatment plant.
Depending on the size of the cesspool tank, the property and the number of occupants, the cesspool can fill up quickly and needs to be emptied regularly, at monthly, quarterly, or annual intervals as required.
Keeping a record of your empties to get an average time scale is useful to book your empties in advance. Due to having no outlet, when a cesspool tank over fills it has nowhere to go other than to come out the top of the tank and spill over your lawn/patio or worst case back up the inlet pipe causing strong odours in the house and toilets that won’t flush!
