Septic tanks, cesspits, treatment plants and pump stations emptied, serviced and repaired in Cranleigh and the Low Weald villages around it.
Cranleigh lies about eight miles south-east of Guildford, in the Borough of Waverley, between the greensand hills at Winterfold and the Sussex border. The village is on the main sewer, but it’s surrounded by farmland, woods and scattered hamlets where homes have relied on their own drainage for generations.
That mix keeps our crews busy here. Out on the lanes it’s septic tanks, cesspits and treatment plants at cottages, farmhouses and converted barns. In and around the village, a lot of new housing has gone up in recent years, and some of those homes depend on pump stations to reach the sewer.
Whatever you’ve got, our own tankers and engineers look after it, and someone picks up the phone at any hour, including weekends and bank holidays.

From Smithwood Common to Alfold, we empty tanks and cesspits for homes and farms that sit beyond the reach of the sewer. Our crews look the tank over on every visit and tell you if something needs fixing.

Treatment plants are a common fit on the heavy ground around Cranleigh. We service them once a year or more, clean and test the moving parts, and leave a written record of what we found.

Whether it serves one house or a whole close, a pump station needs regular checks of its pumps, floats and alarm. We service them, repair faults and can empty the chamber with our own tankers.

A septic tank survey shows what system a property really has, where it drains to and whether it meets the General Binding Rules. It’s worth doing before you exchange on a rural home.

Greensand hills to the north, Wealden clay to the south.
Much of the parish south of the hills is heavy clay. It drains slowly, so soakaways and drainage fields need careful design and regular emptying.
Most local streams feed Cranleigh Waters, which joins the Wey at Shalford. Systems discharging to them must meet the General Binding Rules.
New estates have been added around Cranleigh in recent years. Check whether your pump station is private or adopted before something goes wrong.

Questions answered
What people in and around Cranleigh ask us most.
Look at your water bill. If there’s no charge for sewerage, the property almost certainly has its own system. Your deeds or the seller’s information should say what it is, and we can locate it if nobody knows.
It can, but it needs to be designed for slow-draining ground and protected by regular emptying. Where a field won’t cope, a treatment plant discharging to a ditch is often the better answer. Ask us about drainage fields.
It depends whether the water company has adopted it. If not, it’s usually looked after by a management company or the homeowners. Your sale documents should say, and we can service it if it’s private.
Yes. Rudgwick and the villages south of Alfold are part of our regular work, as are the Horsham district villages beyond them.
If it drains directly into a ditch or stream, the General Binding Rules say it must be upgraded. Read the rules on GOV.UK, or ask us for a survey.
Yes. Our crews are around Cranleigh most days and the phone is answered day and night. Call 03333 233566.
