The San Antonio Water System (SAWS) and the energy solutions company, Ameresco, have entered into a 20-year partnership to treat 900,000 cubic feet of gas and transfer it to a neighboring commercial gas pipeline and sell it on an open market, according to a statement. "In return, SAWS ratepayers will receive a royalty on the sale of the gas, estimated at $200,000 a year, reducing the cost of SAWS operations and keeping rates affordable," said the statement.SAWS previously burned off the biosolids using flares, so the new recycling plan represents a major turning point for the public utility owned by the city of San Antonio.
