Southern Water is progressing work on its £28million upgrade the existing wastewater treatment works at its Horsham site on the Southwater Bypass.

The upgrade to existing facilities will improve efficiency and will also include new machinery, the replacement and refurbishment of existing equipment, and control and monitoring systems.
Southern Water has been working with CMDP – a joint venture between Costain and MWH Treatment. Upgrades to the existing site started in September 2022 and are expected to be complete in summer 2024.
The water company said the work will bring several benefits to customers in and around the local area, ensuring the safe disposal of treated wastewater back into the River Arun for years to come.
This will include landscaping and habitat enhancements that will ensure an overall 9% gain in biodiversity (animals, plants, and fungi) within the site.
There will be no visible alterations to the existing landscape that can currently be seen from the surrounding area or from the A24 either.
Local suppliers are being used where possible within a 30-mile radius of the site, along with two apprentices from the Sussex area.
