What a plant does

Most plants work the same way, in three stages inside one buried tank.

Settle
Waste from the house runs into the first chamber, where the solids sink and stay.
Treat
Air pumped through the middle chamber feeds the bacteria that clean the water.
Clear
What’s left settles out, and clean water runs on to a drainage field or, where allowed, a stream.

Sized to the house

A plant is sized by how many people the house can sleep, not by how many live there now.

The usual guide: up to three bedrooms, five people; one more for each bedroom after that. Scott checks it on site.

5 people for 1–3 bedrooms

6 people for 4 bedrooms

7 people for 5 bedrooms

8 people for 6 bedrooms

9 people for 7 bedrooms

10 people for 8 bedrooms

That’s who the plant is sized for.

Putting one in

Size it
Scott looks at the house, the ground and where the water can go, and picks the plant to suit.

When you need one

The four reasons people usually ring about a plant.

Ask Scott about a plant

A septic tank runs into a ditch or stream

In England, the general binding rules don’t let a septic tank discharge straight to a ditch, stream or river. It has to be replaced or upgraded: with a drainage field, or a treatment plant in its place.

The house isn’t on the mains

A new build, a barn conversion or an annexe away from the public sewer needs its own treatment.

An old plant or cesspit is giving up

Smells, alarms, or emptying more and more often. A new plant can go in its place.

You’re adding bedrooms

More bedrooms mean more people to size for, so the plant may need to grow with the house.
