CLEARMASTERS
Septic tanks and cesspits on the hills
We empty septic tanks and cesspits at homes, farms and estates around Haslemere. Tell us about steep drives or narrow lanes and we’ll bring the right tanker and enough hose to reach the tank.
Learn moreHaslemere sits in a bowl of wooded hills in the far south-west of Surrey, right where Surrey, West Sussex and Hampshire meet. The town is on mains drainage, but the scattered homes, farms and estates on the hills around it, from Hindhead and Grayswood to Blackdown, Linchmere and Fernhurst, very often have septic tanks, cesspits and treatment plants.
This is steep greensand country. The sandy soil drains well, but houses are often reached by narrow, winding lanes or long, steep drives, and the tank may be well below the house or far from where a tanker can park. Getting access right is half the job.
Our crews are in the area most days and we answer the phone 24 hours a day, 365 days a year.

What we do for Haslemere customers
Treatment plant servicing
Hillside plants often sit well away from the house, half hidden in woodland, and get forgotten until something smells. A yearly visit from our engineers keeps the blower and diffusers working and catches problems before the neighbours notice.

Pumped systems and repairs
On sloping sites, some homes need a pump to lift waste up to a tank or plant. When a pump, float or control panel fails, we find the fault and fix it.

Surveys and upgrades
Many houses on the hills were built long before anyone worried about where the outlet went. A survey traces it, checks the tank and tells you whether you’ll need to budget for an upgrade before the next sale.

Drainage around Haslemere: what to know
Steep hills, sandy soil and three counties.
Steep access
Many homes are down steep drives or narrow lanes. Telling us about access in advance means the job goes smoothly.
Sandy greensand
The soil drains well, which helps soakaways, but heavy rain can wash silt into tanks and chambers.
Three councils
Haslemere is close to the West Sussex and Hampshire borders. Planning for new drainage depends on which side you’re on.

★★★★★Clearmasters Ltd did a great job of servicing and emptying our sewage treatment plant. The team turned up on time, were very polite, efficient and gave me lots of advice on maintenance. The office team are extremely helpful also. I'd thoroughly recommend them.

★★★★★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
★★★★★So glad we found them. The team was professional, courteous and helpful. They came the next day and pricing is way more competitive than a national chain. Will be using them again in a year's time to service the pump. Thanks again!
How it works
What happens when you book
Simple and the same every time.
-
Step 1
Tell us what you’ve got
Call us or book online and tell us what system you have and how to reach it. Photos of the drive or lane help.
-
Step 2
We come out and do the job
We book a date and send the right tanker or engineer. It helps if:
- you warn us about steep, narrow or single-track lanes
- tank lids and plant covers are uncovered and not hidden under planting
- gates are open or you tell us the code, and dogs or livestock are kept away
-
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
Haslemere septic tank FAQs
What homeowners around Haslemere ask us most.
My tank is a long way below the house. Can you still empty it?
Usually, yes. Our tankers carry long hoses and powerful pumps. Tell us roughly how far and how steep, and we’ll plan the right vehicle.
Do you cover the West Sussex and Hampshire side of Haslemere?
Yes. We cover the hill villages in all three counties, including Fernhurst, Linchmere, Grayshott and Liphook.
Our plant is hidden in the woods below the house. Is that a problem?
Not usually, as long as we can reach it with a hose. It does mean faults go unnoticed, so a yearly service and a working alarm are worth having.
My pump has stopped. What should I do?
Use as little water as possible and call 03333 233566. Our engineers carry the most common parts and can fix most faults on the first visit.
Will heavy rain wash silt into my tank?
On sandy hillsides it can, particularly if surface water from paths or drives finds its way into the system. We’ll spot that when emptying and suggest how to keep rainwater out.
Can you help in an emergency?
Yes. Our crews are in the area most days and we answer the phone 24 hours a day. Call 03333 233566.
