Tanks emptied, treatment plants serviced and drains cleared for homes, farms and estates in the Horsleys, Effingham and the villages towards Ripley.
East Horsley is a village of large gardens, mature trees and quiet private roads, strung along the A246 between Guildford and Leatherhead. Its character owes a lot to the first Earl of Lovelace, who bought the Horsley estate in 1840 and remodelled much of it in his distinctive brick and flint style. His buildings, and some of the horseshoe-shaped bridges he built for timber carts in the woods, are still part of the landscape today.
Our work here is a mix. Many homes are on the sewer but sit on big plots with long private drain runs, where roots and age catch up with old clay pipes. Further out, on the downs above the village and across the farmland towards Ockham and Wisley, plenty of houses, farms and converted outbuildings look after their own sewage with a septic tank, cesspit or treatment plant.
Our crews work across Surrey almost every day, and our phone is answered around the clock on 03333 233566 if something goes wrong out of hours.
More about septic tank emptying and treatment plant servicing in East Horsley.
From cottages on the edge of the downs to farmhouses out towards Ockham, we pump out septic tanks and cesspits and tell you if anything looks wrong while we’re there. Regular customers can go on a schedule so the tank never gets close to full.

Plants at converted lodges, barns and newer rural houses around the Horsleys need a proper service at least once a year. Our engineers check them over, measure the sludge and leave a written report for your records.

A silent blower, a high-level alarm or a nasty smell usually points to one failed part. We carry the common ones, so most plants and pumps are running again before we leave.

Long private drain runs under lawns and drives are common in the Horsleys and Effingham. We clear blockages by jetting and use CCTV to show where roots or cracked joints are causing trouble.
Learn moreLocal knowledge
From chalk downs to London Clay in a couple of miles.
Sheepleas and the wooded downs above the village are protected, so changes to private drainage up there may need planning advice first.
Further north, towards Ockham, the London Clay holds water, which makes soakaways and drainage fields slow in winter.
Mature gardens are lovely, but roots find their way into old clay drains. A camera survey shows where.

Questions answered
What people around the Horsleys, Effingham and Ockham ask us most.
Look for one or two large lids in the garden away from the house, and check your deeds or water bill. Homes connected to the sewer pay a sewerage charge; homes with a private system usually don’t.
Usually, yes. We run tankers of different sizes and carry long hoses, so a tank well away from the road is rarely a problem. Tell us about width limits, low branches or soft verges when you book.
On older plots with big trees, roots often get into clay pipes through the joints. Jetting clears the blockage, and a CCTV drain survey shows whether a section needs repairing.
It depends where it drains. A tank that drains to a soakaway or drainage field can usually stay if it’s in good order and meets the other conditions, but one that empties into a ditch or stream has to be upgraded. The GOV.UK guidance sets out the rules, and a septic tank survey will show what you have.
