Mantair Hampshire

Drainability: specialists in septic tank and sewage treatment installations in Dorset, Hampshire, Wiltshire, Somerset

Mantair is the name of a company which designed and produced the Mantair conversion unit. In fact, the business was the first to pioneer the conversion unit concept more than 20 years ago. It has remained one of the market leaders ever since. Due to its longstanding presence within the market and the quality of the design and product, at Drainability we only use Mantair conversion units. We want the best so we use the best for our Hampshire customers.

The Mantair conversion unit is the most popular conversion unit on the market in the UK. It converts your septic tank so that the sewage is treated before it flows from the cesspit. It’s one of the very best upgrade systems available, being reliable and discreet.

It is also easy to fit so that in no time your septic tank will be running as a sewage treatment plant.

Mantair conversion units create effluent which meets all regulating authority standards and guidelines and also offers peace of mind due to the lifetime process guarantee. As a Mantair Licensed Contractor, Drainability can install and maintain Mantair conversion units for all our Hampshire clients.
