Design & Specification

Manufactured by Harlequin manufacturing, who have an unrivalled reputation for quality with over 35 years’ experience in the rotationally moulded plastics storage products industry.
Harlequin Septic Tanks are a one piece moulded septic tank manufactured from medium density polyethylene, CE approved to EN12566-1 and designed in accordance with British Standard Code BS6297.
Designed to provide primary treatment to domestic sewage and wastewater, Harlequin Septic tanks design allows for a high level of settlement resulting in low levels of suspended solids suitable for discharge into an underground drainage field/soakaway system.

How Harlequin Septic Tanks Work.

They operate by retaining solids, allow them to settle out and be partially broken down by anaerobic biological action until the effluent is sufficiently treated to discharge to an underground drainage field/soakaway.

Septic tanks should have ventilation to allow proper operation. We recommend use of carbon air vents with Harlequin Septic tanks. The carbon air vent allows septic tanks to vent, whilst eliminating odours
