The Messy Economics of Septage Treatment

Austin Weidner – Tighe & Bond

This presentation explores the economics of treating septage at three POTWs throughout Massachusetts. Septage treatment can be a challenge given its variability and oftentimes utilities may overlook the hidden operating costs of treating it. However, as demonstrated in these case studies, once the actual costs of septage treatment are understood, local utilities can make more informed decisions around setting prices and improving their operations for receiving and treating septage.
