Cesspools
A cesspool is a large underground holding tank with an inlet only. A cesspool is occasionally the only solution to off mains drainage where the discharge of untreated effluent from a septic tank is not permissible due to unsuitable ground conditions. Occasional or seasonal use, such as a holiday home would be in conducive with the efficient functioning of a packaged treatment plant, so again a cesspool offers a simple effective solution to an off mains drainage problem.
A caravan site disposing of chemical toilet waste that would kill the bacteria in a septic tank or sewage treatment plant, again, must use a cesspool.
We offer a range of GRP cesspools with capacities from 6,000 litres to 85,000 litres.
We sell many cesspools into applications other than sewage such as silage effluent on farms.
In a domestic situation we would usually look at a cesspool last having first explored all other avenues.
Please refer to the “Off Mains” options section.
The reason for this being they are very large tanks to site and install. A single dwelling, of only two occupants, requires a minimum capacity under building regulations of 18,180 litres. This has to be increased by 6800 litres for every additional occupant thereafter. So for a 4 bed house with 5 occupants a cesspool of 40,000 litres minimum capacity would be required. At a water usage rate of 180 litres per person per day (British Water sizing) this would last a maximum of 45 days between emptying. This represents an ongoing cost to the householder of around £2600.00 per year.
Occasionally they provide the only solution. A campsite for example discharging chemical toilet waste must use a cesspool
