Sewage treatment plants produce a level of treatment that allows the resulting effluent to be discharged directly into ditches, streams and rivers. Providing a modern alternative to septic tanks, these systems are the preferred choice for regulators.

Other Drainage and Septic Tank Services

From soakaways to replacement septic tanks and site inspections, Mantair have the experience to find a solution for you.

Septic Tank Soakaway

Every septic tank should have a soakaway / drainage field connected to the outlet of the tank.

A soakaway / drainage field is used for the disposal of the overflow from a septic tank into the sub-strata.

Replacement septic tank

Designed to be installed completely below ground, spherical septic tanks provide a traditional solution to sewage disposal needs for domestic dwellings. However, many authorities in the UK prohibit their use and in most instances a Sewage Treatment Plant should be considered as the first option.
