Septic tanks, treatment plants and pump stations looked after in Hailsham, its new estates and the villages around the Pevensey Levels.
Hailsham has grown quickly, with large new housing estates around an old market town. Those developments often depend on private pump stations looked after by management companies, and servicing them is a big part of our work here.
The town sits on the edge of the Pevensey Levels, a wide, flat wetland of drainage ditches and grazing marsh that’s protected for its wildlife. Villages and farms around it, such as Herstmonceux, Hellingly, Magham Down, Lower Dicker and Chiddingly, very often rely on septic tanks, cesspits and treatment plants, on clay ground and wet levels where drainage fields struggle.
Our crews work in East Sussex most days and we answer the phone 24 hours a day, 365 days a year.
Hailsham’s new estates often rely on pump stations that the water company hasn’t adopted. We service them for management companies, test the pumps and alarms, clean the wet well and respond 24/7 when one fails.

New estates on the edge of a protected wetland.
The Levels are protected wetland. A septic tank discharging into a ditch must be upgraded under the General Binding Rules.
Much of the land is clay or low levels where the water table is high. Drainage fields often struggle in winter.
Many new homes drain to pump stations run by management companies. Check your paperwork to see who’s responsible.
