Drains, gullies and pump stations for Leatherhead’s homes and businesses, and septic tanks and treatment plants for the villages on the Downs.
Leatherhead sits on the River Mole where it cuts through the North Downs, surrounded by the large villages of Ashtead, Fetcham and Bookham. It’s mostly on mains drainage, with business parks and offices close to the M25 and a lot of family homes on established estates.
Our work here covers a lot of ground. In town, it’s blocked and broken drains, CCTV surveys and gullies on business sites. On the higher, more rural ground around Headley, Mickleham and the lanes beyond Bookham, some homes and farms rely on septic tanks, cesspits and treatment plants. Near the Mole, low-lying land can flood.
Our crews are in the Leatherhead area most days and we answer the phone 24 hours a day, 365 days a year.
We clear blocked drains at homes and offices with high-pressure jetting, and survey them with CCTV when they keep blocking. On established estates in Ashtead, Fetcham and Bookham, tree roots and cracked clay pipes are common causes.

Offices, business parks and car parks around Leatherhead need gullies and interceptors cleaned to stop flooding and keep oil out of the drains. Our jet/vac tankers handle both, with waste transfer notes every time.

Some developments and business sites rely on pump stations. We service them, test the pumps and alarms, and respond 24/7 if one fails.

Around Headley, Mickleham and the rural lanes beyond Bookham, we empty septic tanks and cesspits and service treatment plants. We check the system every visit and tell you if anything needs attention.
Learn moreLocal knowledge
A river town between the Downs and the London Clay.
Low ground beside the Mole can flood after heavy rain. Clean gullies and clear drains help water get away.
North of the town, London Clay drains slowly and shrinks in dry summers, which can crack older drains.
On the Downs around Headley, the chalk drains well but supplies drinking water, so private systems must work properly.
