Green is More: The Unseen Energy-Water Nexus
For our city government's operation, what is the biggest energy consumer? Water. 50% of our municipal operation's electric usage goes to pumping and treating waste water from residents and business. Why all the energy?
For one, 50 million gallons of water each day arrive at the Water Pollution Control 50 feet underground, which must be lifted up to the facility to begin treatment. Energy-intensive cleaning processes are used to clean the waste water up to regulated standards so it can be sent back to the river.
What's the second biggest energy consumer? Water again. 25% of our city's
electricity is used to treat water to make it drinkable and then send it your way. Shallow
alluvial wells fed by the river undergo several steps of treatment. Then, booster stations pump the water to all of our 130,000 citizens and
When you conserve water, you're conserving energy. There's always more to going green!
