CLEARMASTERS
Pump stations at holiday parks
Caravan and holiday parks on Sheppey rely on pump stations to cope with summer crowds. We service them before and during the season, test the pumps and alarms, and respond 24/7 if one fails.
Learn moreSheerness is a port town on the Isle of Sheppey, where the Medway meets the Thames. Its docks handle cars and cargo, and industrial sites around the port and Queenborough need interceptors and gullies cleaned. The town is on mains drainage, with flat, low streets where drains run slowly.
The rest of Sheppey is flat marsh and farmland, with many holiday and caravan parks around Leysdown, Warden and Minster. Those parks depend on pump stations and private drainage that work hard in summer, and some homes and farms on the island are on septic tanks, cesspits and treatment plants.
Our crews work in Kent most days and we answer the phone 24 hours a day, 365 days a year.

Septic tanks and cesspits on the island
We empty septic tanks and cesspits for homes and farms on Sheppey. On low marsh ground, cesspits are common and fill fast, so we can book regular collections.

Blocked drains on flat ground
Drains in Sheerness and Minster have little fall and silt up easily. We clear them with high-pressure jetting and survey them with CCTV.

★★★★★We use Clearmasters regularly for our cesspool emptying and can't fault them at all. Always friendly and professional, both on the phone and the drivers. Online credit card payment which makes life easy. Highly recommend.

Questions answered
Sheppey drainage FAQs
What holiday parks, businesses and homeowners on Sheppey ask us most.
When should our holiday park’s pump station be serviced?
Before the season starts, and again during or after it depending on how hard it works.
What happens if our park’s pump station fails in summer?
Call 03333 233566. We can send a tanker to empty the chamber and keep things moving while an engineer fixes the fault.
Do you clean interceptors at the docks?
Yes. We clean interceptors and gullies at port and industrial sites, with waste transfer notes.
Why do homes on Sheppey have cesspits?
Much of the island is flat and low with a high water table, so drainage fields often can’t work.
Do you empty septic tanks around Eastchurch and Warden?
Yes. We empty septic tanks and cesspits across the island.
Are you available out of hours?
Yes. We answer the phone 24 hours a day, 365 days a year. Call 03333 233566.
