Under the partnership, both the firms will work together to deliver Mapal’s floating fine bubble aeration system (FFBA) for municipal and industrial wastewater treatment.

Mapal will support Siemens in the delivery of sustainable systems, product lifecycle costing analysis and industry technology expertise to support wastewater treatment operators.

Thames Water, United Utilities and Anglian Water have already used the FFBA technology.

Commenting on the partnership, Mapal Green Energy CEO Zeev Fisher said: "This is another important milestone marking our growth in the UK market.

"We have successfully sold the FFBA concept to water utilities directly and now we are seeing a high level of interest and adoption from amongst our Tier 1 contactors, which we’re delighted to announce now includes Siemens UK and Ireland."

Siemens UK & Ireland head of energy efficiency & environmental care Stephen Barker said: "Mapal Green Energy represents an innovative technology company and its products and industry knowledge greatly complements our wider strategy to support the wastewater treatment industry through sustainable, cost-effective and cutting-edge technology.

"Demand for smart and energy efficient solutions in the wastewater sector will only rise, particularly among the utilities with AMP6 now underway."
