The portable and compact Portapura sewage treatment tank from Marsh Industries has been specifically designed for temporary accommodation (caravans/travel homes), site offices, site toilets and workshops. The Portapura can be installed above or below ground and treats domestic wastewater to a level that is 25 times better than the recommended EN standard.

What are the benefits of choosing Marsh Portapura?

This compact and portable sewage treatment tank is designed specifically for temporary buildings. Design objectives included performance, running costs, installation, transport and storage, making the Portapura the logical choice for sites where temporary buildings are required.

The Portapura’s compact design provides quick and easy installation (where below ground installation can be achieved in approximately 2 hours) with minimum visual impact on the surrounding landscape as well as simple and safe access for maintenance and cleaning.  Systems can be installed above ground and removed/stored when not in use.

The cost of installing and running the Portapura is minimal when compared to larger, commercial systems making it one of the more cost-effective sewage treatment tanks on the market.

Another benefit of choosing the Portapura sewage treatment tank is its impact on the environment. Being CE approved to BS EN 12566 with an ammonia result that is 25 times better than the recommended EN standard means the Portapura is well within discharge consent requirements.
