Blocked drains, pump stations, septic tanks and treatment plants looked after in Fleet, Church Crookham and the villages of Hart.
Fleet is a big, leafy town with a lot of houses on large plots and a lot of mature trees. The town is on mains drainage, but roots, old pipes and shared drains keep us busy here, along with pump stations on the newer estates around Church Crookham and Elvetham Heath.
Go a mile or two out of town and it’s a different story. Villages such as Crondall, Dogmersfield, Winchfield, Long Sutton and parts of Odiham have homes and farms on septic tanks, cesspits and treatment plants. The ground here is often heavy clay, which drains slowly, so drainage fields can struggle in a wet winter.
Whether it’s a blocked drain in town or a treatment plant in the countryside, one team handles it. Our crews are in Hampshire most days and we answer the phone 24 hours a day.
Fleet’s tree-lined roads are lovely, but roots are one of the most common causes of blocked and broken drains here. We clear blockages with high-pressure jetting, cut out roots, and survey the drain with a camera so you know whether it needs a repair.

Many newer developments around Fleet rely on a pump station that the residents’ management company is responsible for. We service them on a regular schedule, test the pumps, floats and alarms, and respond 24/7 if one fails.

In the villages around Fleet, we empty septic tanks and cesspits for homes and farms with tankers from 2,000 to 4,000 gallons. On heavy clay, a tank emptied regularly keeps solids out of the drainage field and helps it last.

If you have a treatment plant, it needs servicing at least once a year to keep it treating the water properly. Our engineers service the common makes, carry the most common parts and leave a written report.

Trees, clay and a mix of mains and private drainage.
Roots love the moisture in drains. If your drain blocks every year, there’s a good chance roots are getting in through a joint or crack.
Much of the countryside around Fleet is on clay that drains slowly. Drainage fields can flood in winter, especially if solids have been allowed to reach them.
If you live on a newer estate, check whether your sewage goes to a private pump station and who maintains it. It’s usually in your management pack.

Questions answered
The questions people in Fleet and the surrounding villages ask us most.
In Fleet, tree roots are one of the most common reasons. Roots get in through joints and cracks and catch everything that flows past. Jetting clears them for a while, but a CCTV survey will show whether a repair would stop it happening again.
Often, yes. We can cut roots out of the pipe with specialist jetting heads. Whether the drain then needs relining or repair depends on the damage, which a camera survey will show.
Check your management pack or service charge statement. Some pump stations are adopted by the water company, but many on newer estates are the management company’s responsibility.
It affects the drainage field more than the tank. Clay doesn’t let water soak away quickly, so the field can become waterlogged. Regular emptying keeps solids out of it and helps it last longer.
At least once a year. Most also need the sludge emptying about once a year; we can do both on one visit.
Yes. We answer the phone 24 hours a day, 365 days a year. Call 03333 233566 and we’ll tell you when we can get to you.
