Thames Sewer Plan May Be Triple Industry Average: BNEF

Thames Water Utilities Ltd.’s “super sewer” may generate profit at triple the industry average should the company win regulatory approval to build the 4.1 billion-pound ($6.6 billion) project, according to a London researcher.

Proposals by the U.K.’s largest water supplier to pay for the Thames Tideway Tunnel by increasing household wastewater charges by as much as 80 pounds a year may generate after-tax returns on equity as high as 24 percent, Bloomberg New Energy Finance said today. That’s more than three times the estimated 7 percent return for other water utilities, the report showed.
