Drainage Field Installation & Septic Tank Conversion Near Petworth

Location: Near Petworth, West Sussex
Services: Drainage Field Installation and Airseptor Septic Tank Conversion
Property: Five-bedroom residential property

The Challenge

The owners of a five-bedroom property near Petworth needed to upgrade their existing off-mains drainage system after their soakaway failed and their septic tank was no longer compliant with current requirements.

The property also presented a significant access challenge. There was no straightforward way to bring excavation machinery and materials into the garden, with a wall approximately three metres high and a hedge restricting access.

A new drainage field was required, correctly sized for the property's wastewater requirements, alongside an upgrade to the existing septic tank.

Our Solution

CH Services recommended installing a new drainage field and converting the existing septic tank into a sewage treatment system using Airseptor.

The drainage field was sized to accommodate the five-bedroom property, providing a suitable discharge arrangement for the upgraded system.

To overcome the restricted access, we arranged for the excavator and drainage shingle to be lifted into the garden by crane, over the wall and hedge.

This allowed us to carry out the necessary groundwork without relying on conventional machinery access.

The Installation

We installed the new rectangular drainage field and completed the Airseptor conversion of the existing septic tank.

Once the underground drainage work was finished, we reinstated the surrounding area, spreading the excess excavated soil evenly and sowing grass seed to help the garden recover.

The Result

The property now has an upgraded sewage treatment system incorporating an Airseptor conversion and a newly installed drainage field sized for its five-bedroom capacity.

Despite the challenging access conditions, we completed the installation and left the surrounding garden neatly reinstated.

This project demonstrates how careful planning and specialist access arrangements can make drainage installations possible even where conventional machinery access is restricted.
