SCL worked in conjunction with the prime, sub-contractors and the owner to provide construction management; document and record compliance controls and verification; develop checklist for reviews, cost, and validate adherence to Quality Assurance requirements.
WTD began construction on a new cogeneration system at the plant designed to convert digester gas, a natural byproduct of the solids treatment process, into a source of heat and electricity for plant operations. This $15 million project was funded in part by an $8.2 million grant from U.S. Environmental Protection Agency. When the new cogeneration system is complete, it will produce about 23,000 Megawatt-hours of electricity each year, which is equivalent to the electricity needed to power nearly 2,300 homes.
