Pump stations, drains, interceptors and grease traps for Eastleigh’s homes and businesses, and septic tanks for the rural edges of the borough.
Eastleigh grew up as a railway town, and today it’s a mix of older terraces near the centre, large estates in Chandler’s Ford and Fair Oak, and new developments still being built on the edges. Add the business parks and industrial estates near the airport and the M3, and there’s a wide range of drainage to look after.
New housing here often comes with private pump stations managed by residents’ companies, while the older parts of town have clay drains that crack and block. Business sites need interceptors, gullies and grease traps kept clean. Out towards Durley, Horton Heath and Colden Common, some homes still rely on septic tanks and treatment plants.
We handle all of it, with crews in Hampshire most days and phones answered 24 hours a day, 365 days a year.
We service pump stations for management companies, residents’ groups and businesses, testing the pumps, floats, alarms and control panels and cleaning the wet well. When one fails, we respond day or night and can empty the chamber to stop it overflowing.

We clear blocked drains with high-pressure jetting at homes and businesses across the borough, and survey them with CCTV when problems keep coming back. You get a written report with photos.

Business parks, depots and car parks need interceptors and gullies cleaned; restaurants and canteens need grease traps emptied. We do both on a regular schedule, with waste transfer notes every time.

Some homes towards Durley, Horton Heath and Colden Common are still off the mains. We empty septic tanks and cesspits, and service and repair treatment plants.
Learn moreLocal knowledge
A growing borough with drainage of every age.
If you live on a newer development, find out whether your sewage goes through a private pump station and who’s responsible for it.
Terraces near the centre often have shared clay drains running behind the houses. A blockage in one can affect the whole row.
Interceptors and grease traps need regular emptying and records. A planned schedule makes compliance easy.

Questions answered
What residents, managing agents and businesses around Eastleigh ask us most.

Most need servicing at least once or twice a year. Regular servicing catches worn pumps and sticking floats before they cause an overflow.
Drains shared by more than one house are usually the water company’s responsibility. We can find the blockage and tell you whether it’s in a shared section.
