Rectifying a Neglected Tricel Sewage Treatment Plant in Devon

Overview

The new owners of a four-bedroom property in rural Devon suspected something was wrong with their sewage treatment plant. Our first service visit confirmed it – the Tricel system had not been properly maintained in years and was failing across every major component.

The Challenge

Ammonia at the discharge point was above 50 mg/l. The filter media had been dislodged by sludge build-up, the airline had detached from the diffuser, the sludge return was broken and aeration was minimal. Paint introduced into the system had caused progressive failure throughout.

The WCI Solution

Our engineers believed the plant was salvageable. Working under confined spaces entry protocols, the media was removed and solids cleared. The tank was jetted and cleaned, a new diffuser fitted, new airlines installed, and a Tricel media bundle and sludge return line reinstated to manufacturer specification.

The Outcome

At a two-month follow-up visit, ammonia had dropped to 3.6 mg/l – a clear, compliant discharge. The plant was enrolled in a WCI annual service contract. Rectification saved the cost of full replacement and extended the life of a structurally sound system.
