Saving Water and Energy – the Trickle Down Effect on Your Wallet

By Matt Colip and Walter Higgins

Just like homeowners, wastewater and drinking water treatment facilities have to control their energy usage because their budgets are so tight.  While you and I can install attic insulation or turn off lights when they aren’t in use to lower bills, plans for reducing energy use can be a little more complicated at water and wastewater treatment facilities. Still, there are many strategies available to reduce energy usage at water treatment facilities.  Oh, and you can help too.

One way a treatment facility can trim down its energy use is to start from the source and reduce the overall community demand for drinking water and waste water to be treated.  Less water used in communities means a lower cost to you on your water and sewer bill.  By promoting the use of water efficient WaterSense products and water conservation practices by the citizens within their service area, water utilities can reduce energy use significantly. Just think about how much less water facilities would have to treat and the energy that could be conserved if all of us used even a little less!

Have you ever driven by a waste water plant and noticed a large flame coming off one of the stacks?  That’s gas that is produced in the operations of the plant and is typically burned off.  Instead of flaring, it can be beneficially used to run turbines that can generate heat and electricity for the plant (otherwise known as Combined Heat and Power).  Also, some facilities are beginning to install solar photovoltaic panels on the plant grounds to offset the total electricity used by the plant.

On May 8th, EPA, in partnership with the Pennsylvania Department of Environmental Protection, hosted an Energy Roundtable Conference in Harrisburg for wastewater treatment operators interested in reducing their facilities’ energy costs and ultimately their carbon footprint.  This conference highlighted several areas related to energy efficiency along with innovative solutions to wastewater treatment.
