Specialists in the installation of Residential Sewage Treatment Plant Systems throughout Hertfordshire

Welcome to

Willowmead Treatment Plants

What is a Sewage Treatment Plant?

A Sewage Treatment Plant or septic tank, simply breaks down your waste by introducing air and bacteria. Clean water can then be discharged safely without harmfully affecting our sensitive environment.    

Are you Regulation Compliant?

New Environment Agency rules mean your septic tank or pit must no longer discharge into a soakaway, ditch or watercourse.

By Jan 1st 2020 you must have upgraded to a sewage treatment plant or diverted your outlet to a correctly Designed Drainage field. Drainage Fields are often costly to construct and require large areas, so our Sewage Treatment Plants provide a simple, reliable and compliant solution to ‘off main drains’ situations.
