Bucks County Water and Sewer Authority (BCWSA): Energy performance

Energy Performance
Cumulative (vs. Baseline)37%
Annual (2018)12.8%

Better Buildings, Better Plants Challenge partners strive to decrease source energy use intensity (EUI), and to increase the percent improvement compared to a set baseline year.  As part of the Better Plants Challenge BCWSA have pledged to improve the energy intensity at 4 treatment plants by 25% over a 10 year period.  This voluntary pledge aligns with BCWSA’s existing commitment to sustainability which has been highlighted by the completion of a number of large projects in recent years including the installation of a 100,000 kW solar array, motor system upgrades, and HVAC focused optimizations. With an energy intensity improvement of 37% since its baseline year of 2012, BCWSA has met its 25% reduction in energy intensity target in 2018.


Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. 100% of BCWSA's facilities participating in the Challenge have improved energy performance by >15% since the baseline year of 2012. Two of BCWSA's 4 facilities have experienced improvements greater than 35% and the remaining two have their total improvements since 2012 between 15-25%.  


BCWSA is one of the largest water and wastewater treatment agencies in the state of Pennsylvania and treats wastwater from facilities in the surrounding Bucks County area, and calculates energy intensity in terms of source purchased energy consumed (in MMBtus) per million gallons of influent water flow. The percent change in energy intensity is tracked for each facility on both a monthly and annual basis. These metrics are rolled up to the corporate level, with a corporate-wide percent improvement in energy intensity calculated by taking a weighted average of the percent change in energy intensity at the individual facilities.
