Septic Tank Installation in Petworth: The Complete Process
2 min readPetworthBy AA Drainage
A new septic tank is a big job, but with the right planning it runs smoothly. Here is our process for Petworth installations.
Before work starts
We:
- Survey the site and access routes
- Carry out a percolation test
- Size the tank for the household
- Design the drainage field
- Check regulations and any permits
Installation
The tank is lowered into a prepared excavation, set level on a base and backfilled carefully. Drainage field trenches are dug, filled with stone and fitted with distribution pipes.
Handover
We test the system, reinstate the ground and explain how to look after it, including when to book the first empty.
Frequently asked questions
Do I need planning permission?
Not always for a replacement, but new systems may need Building Regulations approval.
How big a tank do I need?
It depends on the number of people the property serves. We size it for you.
