The campus sewer system has 100 sewer manholes and 11,000 feet of sewer piping. The system was recently upgraded in co-junction with the Waterville Sewerage District, which is also the authority having jurisdiction over the Colleges activities and conveys our sewerage to the Kennebec Treatment Facility.
The Central Steam Plant has both oil and biomass boiler providing steam to the campus. The plant was brought on line in 1993 with the addition of the biomass boilers in 2012. Peak winter loads average 43,000 pounds of steam per hour. During the heating season, the 300 psig steam is piped through a turbine generator that exhausts steam out to campus at 50 psig. This process is typically called "co-generation". The steam is distributed through an underground distribution system that is approximately 9,000 feet in total length. This underground distribution system not only carries steam to the campus buildings, but also returns the condensed steam back to the plant. The turbine generator was brought on line in 1999 and produces approximately 10$ of the campus damand each year. The steam plant produces over 130,000,000 pounds of steam per year. The Central Steam Plant operates 24 hours per day, 365 days per year.
The College maintains a separate storm water system that conveys storm water from parking lots, roads, and from building perimeter drainage systems. This water is conveyed to outfalls and detention ponds across the campus property.
The campus maintains its own distribution system consisting of a pump house, that takes incoming city water and boosts the pressure, a 158,000 gallon storage tank, and over 11,000 feet of underground water mains.
