Severn Trent ‘Poo Power’ Helps Fuel Homes, Save on Costs

Extracting energy from “processed poo” to help power homes in the Birmingham area is what Severn Trent Plc, Britain’s second-largest publicly traded water company, is now doing to generate a cost-saving renewable gas.

The utility’s clients near the Minworth treatment plant are able to cook food with “green gas” produced from their own sewage after Severn Trent started injecting the bio-methane into the gas grid last week. The gas becomes as clean, “exactly the same,” after treatment as normal gas, the first time in the U.K. a water company has delivered bio-methane to the grid. Companies previously used it only on-site.
