Part of the anaerobic digestion of biosolids from our wastewater creates renewable energy for us on site in the form of methane gas. On average, Rivanna produces 32,725,000 cu ft of methane each year that is captured for use at our Moores Creek Water Resource Recovery facility. This amounts to a little over 1.1 million kWh of energy each year which would power almost 80 homes a year! A cogenerator burns the gas and produces electrical power that can be distributed within the facility’s internal grid, thereby reducing the amount of external energy that we are required to purchase to run our operations.
