Overview
West Stone in Devon was undergoing a full refurbishment and needed both a new sewage treatment plant and a rainwater harvesting system. WCI Water & Wastewater Engineers specified both, co-locating them in a single shared trench.
The Challenge
The client specified a non-electrical sewage treatment solution. Both systems needed to be coordinated around the wider refurbishment programme, with percolation tests confirming drainage field capacity.
The WCI Solution
WCI installed a Biorock non-electrical STP with pumped discharge to a drainage field, certified to BS EN 12566-3:2005 and sized to British Water guidelines. A Klargester Raintrap 14,000-litre rainwater harvesting system was installed alongside for grey water and garden irrigation, with 18 days’ storage to BS 8515.
The Outcome
Both systems operational and maintained under a WCI service contract.
