Septic tanks, cesspits and treatment plants emptied, serviced and repaired in Heathfield and the farming villages of the High Weald.
Heathfield is a small market town on a ridge in the heart of the High Weald, surrounded by rolling farmland, woods and scattered villages. Away from the town centre, a very large share of homes and farms, in places like Cross in Hand, Waldron, Punnetts Town, Warbleton and Burwash Weald, have septic tanks, cesspits or treatment plants.
The High Weald’s clay and sandstone, steep valleys and narrow lanes make private drainage here more demanding than in most places. Drainage fields on clay struggle in winter, old tanks are common on farms and cottages, and access often needs planning.
Our crews work in East Sussex most days and we answer the phone 24 hours a day, 365 days a year.
We empty septic tanks and cesspits across the Heathfield area, from farmhouses to small cottages. Many systems here are old, so we check the tank, baffles and outlet every time and tell you honestly what we see.

Treatment plants have replaced many old tanks around Heathfield. They need servicing at least once a year to keep the water they discharge clean. Our engineers service the common makes and leave a written report.

When a plant’s alarm sounds or it stops working, our engineers find the fault and fix it, carrying the most common parts with them.

If your old tank discharges to a ditch or stream, it has to be upgraded. We survey the site, recommend what will work on your ground, and install a treatment plant or drainage field.
