Harlequin CAP6 (up to 6 Population)
Direct Drainage Reviews

The CAP6 is a compact sewage treatment plant designed specifically for domestic installations for up to 6 inhabitants (4 bedrooms). It is a Continuous Aeration Plant which operates using a unique bio-media system and delivers a pollutant removal level of 96.2% whilst also combating common problems associated with small packaged domestic plants. It comes in gravity and pumped outlet versions. Integrated pump outlets are useful where gravity drainage is not possible.


Bio Media System – Similar to the Moving Bed Biological Reactor (MBBR) system, there is no fixed media eliminating blockages that are commonly found in smaller treatment plants.

Durable & Stable Product – Made from tough durable polyethylene, it is easy to transport and has a wide base for stability.

Saves Money – With an easy installation due to the systems compact size and light weight, it also promotes low maintenance reducing costs.

Easy Maintenance – At full occupancy, the system only need to be emptied every 6 months, with maintenance of the compressor easily carried out via the external housing.

Compact System – A perfect compact solution for homes of up to 6 inhabitants (4 bedrooms).

Low Noise – With a near silent air compressor housed externally, the operation of the system is virtually inaudible.
