Septic Tank
Replacement

Replace an old, failing or non-compliant septic tank with a modern sewage treatment plant. Full design, install and reinstatement.

Failing Septic Tank?
We'll Sort It.

Since the Environment Agency's General Binding Rules came into force, many older septic tanks that discharge to a watercourse are no longer compliant and must be replaced or upgraded — typically when a property is sold or when the system fails. Our team handles every aspect of septic tank replacement, from initial inspection to commissioning of the new system.

We carry out a percolation test, recommend the right sewage treatment plant for your property, decommission the old tank safely and install the new system with a new drainage field or compliant discharge. The whole site is then reinstated so it looks like we were never there.
