Harlequin CAP12 Sewage Treatment Plant | Continuous Aeration | Up to 12 People | CAP12

Harlequin CAP12 Sewage Treatment Plant

The Harlequin CAP12 is a continuous aeration sewage treatment plant for homes and buildings with up to 12 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. The tank is one piece medium density polyethylene with a bio media system, and Harlequin quote 96.2% pollutant removal.

Choose the outlet, inlet depth and alarm from the options above. The price shown first is for a gravity outlet at the standard inlet depth with no alarm. 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. If it discharges to a watercourse or to ground in England it must meet the Environment Agency general binding rules, otherwise you’ll need a permit. Scotland, Wales and Northern Ireland have their own rules, so check with SEPA, Natural Resources Wales or NIEA before you install.
