Cesspool 2800 from Clearwater
Spherical Cesspools are manufactured as standard from 2,800 to 4,600 litres net working capacity. Cylindrical cesspools are available with capacities from 18,000 to 26,000 litres.
The cylindrical tank allows for a reduced depth of excavation in comparison with the same sized spherical tank, offering considerable savings where ground conditions are difficult or where there is a high water table.
Cesspools are designed for storage only, with their contents being emptied at regular intervals using tankers. High Level Alarms with audible and visual warnings are available for all tanks to enable level monitoring for optimum use.
When sizing a storage tank for domestic properties it should be noted that Building Regulations require a minimum capacity of 18,000 litres (2 people) under Environment Agency regulations.
When positioning units, there are a number of factors to be considered - systems should not be placed closer than 7 metres to any dwelling and as far as possible from any watercourse, normally not less than 10 metres. Adequate access for tankers to empty should also be taken into consideration.
Cesspools (sometimes called cesspits) are like Septic Tanks but with a big difference – they are not connected to a soakaway, which means they must be emptied once full.
Cesspools are usually temporary solutions until a property can either be connected to mains drainage or a sewage treatment plant is installed, although places such as camping and caravan sites often use them to hold and dispose of chemical/sewage waste.
They do however have a number of disadvantages that should be considered, for example since they need ventilation to stop gas building up inside, they tend to be smelly and of course the gases are toxic so they should not be inspected – people have passed out and fallen into cesspool tanks.
If you’re considering a cesspool because you can’t get permission to discharge effluent from a septic tank then why not think about a sewage treatment plant instead? Sewage treatment plants are not just better for the environment but they can can save you £££’s every year, partly because they do not need emptying nearly so often as a cesspool – an increasingly expensive business. (For those who live north of the border you should also be aware that cesspits and cesspools are illegal in Scotland.)
