The eco-friendly way to treat and dispose of wastewater from homes, businesses & industry

When you need to easily dispose of wastewater from properties not connected to mains drainage


A biodigester is a treatment plant that safely treats and disposes of wastewater from properties without access to black and grey water drainage.


The tank uses natural micro-organisms and oxygen to break down solids in the wastewater. Biodigesters in our range produce a clear odourless effluent for safe disposal.


Biodigesters are available in a wide range of sizes for homes and businesses and are self-contained. No chemicals are needed and some do not need to be emptied at all, so nasty work is avoided.

Your Biodigester works for you

Tried and tested designs you can rely on 

Burnham Environmental Ltd. has made Biodigesters for over 25 years. We offer the widest range of treatment plants for wastewater, sewage and industrial effluents.


Because your Biodigester uses organic means to break down the wastewater, harsh chemicals that can harm the environment are not normally required.

Suitable for variable loadings

Biodigesters in our range are suitable for variable loadings at sites such as caravan parks, pubs, restaurants and hotels.

Reduces phosphorus by 99%

The PHR Range of Biodigesters are specifically designed to reduce 99% of phosphorus from your wastewater.
