How Can Public Water Utilities Save On Energy Costs?

I think that in this day and age, everyone knows a variety of ways to conserve at least a little bit of energy and save money while doing so. This is true at home, and across any industry. Take for instance the energy consumption across the United States just in the water treatment process. With thousands of water public utilities across the nation, the amount of energy usage is significant enough to make the statistical charts. 

Energy use and costs vary by water treatment plants. This depends on a number of things including the region (local energy tariffs and landscape), the type of treatment process, the level of treatment, the size of the treatment plant and condition of the piping network. Of all the processes, pumping of water into the plant and the distribution systems is the most costly. This can represent 15% to over 70% of the total energy usage at a water treatment plant, and the water treatment cost can range from 15% to over 50% of the overall operating cost.

The Northwest Energy Efficiency Alliance (NEEA) states that “efficiency is the most cost-effective way to meet our future energy needs” and facilities can save between 5% and 20% of their total energy consumption by installing energy-management systems. It stands to reason that anything that can be done to materialize the reduction of energy usage and its costs is a win-win scenario. This is not only good for the environment, but for the public’s pocket. Proper operation of pumps is a must.
