Engineers are finalizing design for a 17-mile-long pipeline that will deliver methane gas from a landfill in Muskego, Wis., to fuel a wastewater treatment plant in Milwaukee.
The pipeline is the first step in an $80-million investment that will save the Milwaukee Metropolitan Sewerage District (MMSD) at least $148 million over the next 20 years by enabling its Jones Island plant to generate its own heat and electricity by burning landfill-generated methane instead of natural gas.
