CLEARMASTERS
Septic tank and cesspit emptying
From cottages at Abinger Common to farms near Walliswood, we pump out septic tanks and cesspits on a schedule that suits the household. Each load leaves with a waste transfer note for your records.
Learn moreAbinger isn’t one village but a string of them: Abinger Hammer on the A25, Sutton Abinger and Abinger Common on the hillside above, and Forest Green, Walliswood and Oakwood Hill well to the south. The parish is in Mole Valley, and every part of it lies inside the Surrey Hills National Landscape.
Homes here are spread out and few lanes are wide. A great many properties have their own septic tank, cesspit or treatment plant, and some share one with the neighbours. The ground varies too, from chalk in the north to sand in the middle and clay in the south, so no two systems behave quite alike.
Our crews are in the Surrey Hills almost every day, and someone answers the phone around the clock. Tell us where you are and what you have, and we’ll bring the right kit.

What we do for Abinger homes
Treatment plant servicing
A yearly visit keeps a treatment plant clean and within the rules. We check the blower, pumps and alarms, check the sludge level and tell you plainly if anything is wearing out.

Fault finding and repairs
If a plant alarm is sounding or the tank smells, our engineers trace the cause and fix it, often with parts from the van. That includes blowers, float switches, pumps and control panels.

Surveys before buying or upgrading
Buying a house in the parish? A survey tells you what drainage it has, what condition it’s in and whether it meets the General Binding Rules, before you exchange contracts.

Drainage in Abinger: what to know
One parish, three kinds of ground.
Chalk and the Tillingbourne valley
Around Abinger Hammer and Sutton Abinger, the river and its springs mean any discharge needs care. Keep your plant serviced if it drains to a stream.
Greensand hills
Abinger Common and the slopes below Leith Hill are sandy. Soakaways usually drain freely, but the lanes are steep and narrow.
Weald clay in the south
Forest Green, Walliswood and Oakwood Hill sit on clay, where drainage fields can stay wet from autumn to spring.

★★★★★I have been using Clearmasters since I moved into a house with a klargester in 2015. Since then, they have carried out all the regular visits for empties, as well as service checks. I can’t speak more highly about their level of service and professionalism. Very friendly guys, always leave the place in good order, never had an issue. Highly recommend for anyone needing a similar service.

★★★★★Absolutely phenomenal service from Clearmasters. Not only did they come out and fix our drainage with a moments notice, they did it with a smile on their face and were extremely polite, helpful and knowledgable whilst doing so. After being let done by another local company, Clearmasters came to our rescue. A massive thank you to both Max and Matt. Highly, highly recommend
★★★★★We have been dealing with Clearmasters for many years now. In fact over 25 years. They have always been 100% reliable, work with integrity, and have completed the clearances without any fuss. We would certainly recommend them.
How it works
What happens when you book
The same three steps every time.
-
Step 1
Tell us what you’ve got
Ring or book online and tell us what system you have, where it is and what’s wrong. If the property is up a track or behind a gate, mention that too.
-
Step 2
We come out and do the job
We agree a date and send a tanker or engineer to suit your access. It helps if:
- there’s room for a tanker within reach of the tank, and you tell us if the lane or drive is narrow
- lids and covers are uncovered and easy to find
- you let us know about any gates, codes or animals in the field
-
Step 3
Paperwork and the next visit
You get a waste transfer note for anything we take away, and a written report after a survey or service. If it’s a regular job, we’ll remind you when the next one is due.

Questions answered
Abinger septic tank and treatment plant FAQs
What homeowners across Abinger parish ask us most.
Which council deals with drainage planning in Abinger?
Abinger is in Mole Valley, so planning questions go to the district council there. The Environment Agency sets the rules on what a system may discharge, and because the parish is in the Surrey Hills National Landscape, approvals can take a little longer.
Is a cesspit a good idea at the southern end of the parish?
Sometimes. Where the clay is too heavy for a drainage field and there’s no ditch to take treated water, a sealed cesspit may be the only option. It needs emptying often, so most owners prefer a treatment plant where the site allows one.
How often should a septic tank in Abinger be emptied?
For most households, about once a year. A big family with a small tank may need it done more often. We’ll suggest a schedule after the first visit and remind you when the next one is due.
What if I don’t know where my tank or plant discharges?
That’s common with older properties. We can trace the pipes with dye or a camera and map the route, so you know whether it goes to a field, a soakaway or a ditch. That matters for the rules and when you come to sell.
Do the General Binding Rules apply to my system?
They apply to every small sewage system in England that discharges to the ground or to water. The rules are on GOV.UK, and a septic tank survey will tell you whether yours complies.
Can you come out in an emergency?
Yes. We take calls every hour of every day, and our crews are in the Surrey Hills almost daily. Ring 03333 233566.
