Marsh Ultra:Polylok L sewage treatment plant. Industrial performance with domestic simplicity.

Published:  11 September, 2018

Marsh Industries has launched its latest innovation in domestic sewage treatment plant technology, the Marsh Ultra:Polylok L (UPL).

The UPL draws upon Marsh Industries’ extensive experience in the industrial/commercial sewage treatment sector bringing its outstanding performance and value-engineering to the domestic sector.

Available in 6 and 12PE models, the Marsh UPL is tested and approved to BS EN12566-3 and boasts a minimum effluent quality of 20:30:20 (BOD:SS:NH3), well within national consent standards. Designed with merchants and installers in mind with a circular footprint of Ø1700mm and a maximum height of 2050mm for the UPL 6PE, the system is compact, safe, quick to install and requires minimal annual maintenance.

Marsh Industries is committed to supplying its loyal merchant network with the most comprehensive range of sewage plants available from a single UK manufacturer. The new UPL provides merchants with an additional system option to ensure they can compete with any similar sized competitor product whilst maintaining their profit margin.

Managing Director, Steve Boyer; “The launch of the UPL comes at a time of accelerated growth for Marsh Industries. This product heralds the beginning of a number of revolutionary new products which will be introduced over the next six months.”

“The company has invested heavily in new products and processes, not to mention expansion of our manufacturing and distribution plant at Bridgwater, and the launch of this new product underpins our commitment to our customers, merchants and the industry as a whole.”
