The Challenge
Burnley Crematorium’s existing septic tank and filter bed had failed, causing the surrounding area to flood. The situation presented a serious environmental risk, with potential pollution threatening a nearby watercourse.
The failing system needed to be fully replaced, but the project came with a significant logistical constraint: the available site area was confined, and any new installation would need to occupy the same footprint as the original tank — which first had to be removed.
Our Solution
Drain Alert carried out a comprehensive CCTV drain survey to assess the full extent of the drainage infrastructure and identify the root cause of the failure. Based on the survey findings, our team recommended the installation of a new sewage treatment plant as the most effective long-term solution.
Working with the crematorium to establish typical weekly attendance figures, we calculated the required capacity and specified a Clenviro CLF5 Sewage Treatment Plant, rated for up to 30 persons. The CLF5 system features a unique combination of aerobic and anaerobic treatment technologies, delivering superior treatment performance. The unit incorporates a settling tank, an anaerobic digester, and a biological filter — ensuring effective, efficient, and environmentally compliant treatment of all wastewater.
Despite the confined site area and the need to first remove the old tank from the same location, the installation was completed smoothly and without disruption to the crematorium’s operations.
The Outcome
The new treatment plant has fully resolved the flooding and eliminated the pollution risk to the adjacent watercourse. Burnley Crematorium now benefits from a modern, high-performance sewage treatment system designed to handle its specific capacity requirements, with minimal maintenance demands and full environmental compliance.
This project demonstrates Drain Alert’s ability to deliver technically sound drainage solutions in constrained environments – from initial CCTV investigation through to specification, procurement, and installation.
