Upgrading a Septic Tank to a Treatment Plant in Horsham
2 min readHorshamBy AA Drainage
Many septic tanks in the villages around Horsham discharge to ditches. Under the General Binding Rules these must be upgraded, and a treatment plant is often the best answer.
Why a treatment plant?
On heavy Weald Clay, a drainage field may need to be very large. A treatment plant produces much cleaner water and, where allowed, can discharge to a watercourse.
The upgrade process
A typical upgrade involves:
- Site survey and checking discharge options
- Emptying and decommissioning the old tank
- Excavating and installing the new plant
- Connecting power and pipework
- Commissioning and handover with maintenance advice
Ongoing care
Treatment plants need an annual service and regular emptying. We can set up reminders so it never gets missed.
Frequently asked questions
Can the old tank be reused?
Sometimes it can be converted into storage or removed. We advise on a case by case basis.
How noisy is a treatment plant?
Modern air blowers are quiet and usually housed in a small cabinet or the tank lid.
