Types of Off-Mains Drainage
Many homes like plots are not located near main sewers. This is where off-mains drainage systems come in. Let’s take a closer look at what they are and how they work.
A cesspool is a type of holding tank with no inlet or outlet. It holds sewage until it is emptied into a disposal lorry. These tanks need to be emptied up to eight times a year. they can hold up to eight weeks of sewage at a time.
A septic tank is similar to a cesspool but it has a difference. It has a compartment for solid waste and liquid waste separately. Solids are kept in the tank, while liquids are removed and cleaned with percolation. Solids also need to be emptied once or twice per year.
Sewage treatment plants allow for compressed air to enter the tanks. This will help to speed up the breakdown process. There are rotating disks in these tanks so that it has a larger surface area for organisms to do their work. These are more expensive than septic tanks but have lower running costs.
A soakway allows water to slowly soak through soil. This can be a system of interlinked trenches with a perforated pipe. Or it can be a pit filled with rubble and stone. The design you choose will be determined by the amount of space you have available.
