CLEARMASTERS
Our tankers and engineers work in Kent most days. Sevenoaks, Tunbridge Wells and the west of the county are a short drive from our office in Smallfield, and our crews cover the whole of Kent, from Dartford and the Medway Towns to Thanet, Dover and Folkestone.
Kent’s drainage is as varied as its landscape. The Weald in the south-west is heavy clay where drainage fields struggle. The North Downs are chalk that supplies drinking water. The Stour catchment around Canterbury and Ashford drains to the protected Stodmarsh wetlands, and Romney Marsh and Sheppey are flat and wet. Along the Thames and around the ports, logistics, freight and industry mean a lot of interceptors and pump stations.
Every town below has its own page explaining what we see there and which villages we cover. Wherever you are, you get the same team, the same paperwork and the same 24-hour phone line.

Local knowledge
What drainage looks like in Kent
Weald, downs, marsh and a lot of industry.
-
The Weald
Around Tunbridge Wells, Maidstone and Ashford, heavy clay drains slowly and drainage fields struggle in winter. Many farms and oasts are off the mains.
-
The North Downs
Around Sevenoaks, Gravesend, Dover and Thanet, the chalk supplies drinking water, so septic tanks and treatment plants must work properly.
-
The Stour and Stodmarsh
Around Canterbury and Ashford, new homes must be nutrient neutral to protect the Stodmarsh wetlands, which affects new treatment plants.
-
Marsh and island
Romney Marsh and the Isle of Sheppey are flat and wet, where cesspits are common and holiday parks rely on pump stations.
-
Ports and logistics
Dover, Folkestone, Sheerness and the Thames-side logistics sites need interceptors and gullies cleaned regularly, with records kept.
-
New towns and estates
Kings Hill, Ebbsfleet and Ashford’s new neighbourhoods often have private pump stations run by management companies.

★★★★★I've used Clearmasters for the past year and they've always been outstanding! They are very efficient to deal with in the office, they are very reasonably priced and their engineers are among some of the most professional i've met. I would highly recommend them to anyone.

★★★★★Very friendly and helpful staff. Throughout the initial diagnosis and then the subsequent fitting of new equipment, each step was explained to me such that I understood why it was being undertaken and as a result I was confident that I wasn't being ripped off. Will use Clearmasters for all future services with regard to my treatment plant.
★★★★★Have always found Clear Masters to be very friendly, professional and helpful. They provided the service to me on time at the pre-agreed amount

Questions answered
Kent septic tank and drainage FAQs
Do you cover the whole of Kent?
Yes. Our crews work across the county most days, from Sevenoaks and Tunbridge Wells in the west to Thanet, Dover and Folkestone in the east.
What does nutrient neutrality mean in Kent?
Around Canterbury and Ashford, new homes in the Stour catchment must show they won’t add nutrients to the Stodmarsh wetlands. It mainly affects new builds and conversions off the mains.
Do you clean interceptors at freight and logistics sites?
Yes. We’re SafeContractor, Achilles UVDB and RISQS approved and clean interceptors and gullies at ports, depots and logistics sites, with waste transfer notes for every load.
Why do homes on Romney Marsh and Sheppey have cesspits?
The land is flat and low with a high water table, so drainage fields often can’t work. A cesspit holds everything until it’s emptied.
Who looks after the pump station on my estate?
If the water company hasn’t adopted it, usually the management company. We service estate pump stations across Kent and respond 24/7 if the alarm goes off.
