Norwegian ship-to-shore reuse system seeks backers

Published February 6th, 2014

A new offshore wastewater treatment concept launched in Oslo today has the potential to offer significant savings to municipal and industrial customers looking to escape the traditional permitting and footprint constraints of land-based effluent treatment plants.

By fitting out a pre-owned sea-going vessel with currently available treatment technologies and connecting it to an onshore wastewater collection network, concept developer Sigmund Larsen and his company EnviroNor hope to secure sufficient interest to be able to sign their first contract next year.

Although he has not yet raised the $75-90 million he estimates it will take to fit out his first vessel, Larsen is confident that the demand is there to support the concept, which has been independently verified by DNV GL.

The main applications would be to provide temporary treatment services during the maintenance of onshore WWTPs, and to treat and reuse wastewater in areas with limited land availability.
