Drainage for one of south Hampshire’s fastest-growing areas: pump stations on new estates, interceptors on business parks, blocked drains in town and septic tanks in the countryside.
Fareham is an old market town at the head of Fareham Creek, surrounded by suburbs that have grown up since the war and some of the biggest new housing developments in south Hampshire, including the new community at Welborne north of the town. That much new building means a lot of new drainage, much of it private.
On a typical week in the Fareham area we might be servicing a pump station that serves a few hundred new homes, emptying an interceptor at Segensworth, jetting a root-filled drain under a 1930s semi and emptying a septic tank at a farmhouse near Wickham. The borough really does have a bit of everything.
Our engineers and tanker drivers are working in south Hampshire most days, and if something fails out of hours there’s always someone on the end of the phone.
A pump station serving a large estate works hard, and a failure affects every home on it. We put stations on a planned maintenance schedule, check every pump, float and alarm, clean out the rag and fat that builds up in the wet well, and send the management company a report after each visit.

In the older parts of Fareham, Portchester Road and the streets around the town centre, roots and cracked clay are the usual suspects. We jet the blockage out, put a camera down the pipe, and tell you plainly whether it needs a repair or just regular attention.

Segensworth, Whiteley and the smaller estates around Fareham are full of yards, depots and car parks. Their interceptors stop oil and fuel getting into the creek and the harbour, so they need emptying and inspecting on a schedule, with the paperwork kept.

Out past Titchfield, Wickham and Funtley, a number of farmhouses and cottages still have a septic tank or cesspit. We empty them, keep an eye on their condition, and look after treatment plants where they’ve been fitted.

A growing borough with lots of new drainage to look after.
New communities like Welborne come with new drainage. Find out early whether your pump station and drains are private or adopted.
Interceptors on industrial sites should be inspected regularly and emptied when needed, with records kept.
Low ground close to Fareham Creek and the harbour can be slow to drain. Clean gullies and drains help.

Why Fareham customers use us
Whether it’s a pump station on a new estate or an interceptor at Segensworth, here’s what you can expect.
Tankers from 2,000 to 4,000 gallons, jet/vac combination units, CCTV survey kit and confined space teams for pump station wet wells.
Regular customers get a reminder when their next empty or service is due.
SafeContractor, Achilles UVDB and RISQS approved, so we can get onto managed sites and meet your contractor checks.
We’ve been emptying tanks and servicing systems since long before most of the kit on the market existed.
After every pump station visit, the management company gets a written report, so whoever pays the service charge can see what was done.
If a pump station alarm goes off at night, there’s a real person on the phone who can get a tanker moving.

Very pleasant and helpful guy operating the equipment. Gave sound advice with ongoing maintenance tips. Will definitely be saving Clearmasters' contact details to use them again.
★★★★★Clearmasters have emptied our Septic Tank for many years. It is not an easy placed tank to get to but the chaps manage perfectly. I find them very efficient, friendly and polite. Thank you Valerie Wise

Questions answered
What residents, managing agents and businesses around Fareham ask us most.
Many are, eventually, once the developer has met the water company’s standards. Until then, the management company is responsible. Ask your managing agent where things stand on your estate.
We test each pump and the floats and alarm, check the control panel, measure how the pumps are performing, and clean out fat and rags from the wet well. Anything that needs attention goes in the report.
Typically every six months, with emptying when the oil or silt reaches the level set by the manufacturer. We can inspect it and set up a schedule for you.
Yes. There are still homes off the mains on the edges of the borough, and we empty and look after their tanks, cesspits and treatment plants.
Not really. It can mean building debris was left in the pipe, or a section was damaged or laid at the wrong fall. A CCTV survey will show what’s going on, and the report can support a claim.
