Harlequin HydroClear HC40 Sewage Treatment Plant

The Harlequin HydroClear HC40 is a sewage treatment plant for homes and buildings with up to 40 people. It treats all the wastewater from toilets, bathrooms, kitchens and laundry so the cleaned water can go to a drainage field, soakaway or watercourse. It uses a moving bed bio media system with an air blower that sits above ground in a weatherproof housing. If the power goes off it keeps working as a septic tank until the power is back. Harlequin quote 97.5% pollutant removal.

Choose the outlet and inlet depth from the options above. An alarm is included as standard. The price shown first is for a gravity outlet at the standard inlet depth. Pick the pumped outlet if the treated water can’t flow away by gravity, as it has a pump built into the tank. Risers are for when your drain comes in deeper than the standard inlet.

Installation and Regulations

A treatment plant must be installed by a competent installer to Harlequin’s instructions and Building Regulations Part H.
