innovation that yield environmental improvements by awarding select facilities with the PISCES award.
“It is an honor for one of Michigan’s wastewater treatment facilities to be recognized by the U.S. Environmental Protection Agency for
innovative and effective protection of the environment,” said Director Chester. “We are pleased to work collaboratively with the
township and facility staff to find new and better ways to keep our environment and our families safe.”
The Delhi Township Wastewater Treatment Plant serves more than 23,000 people in the township, two small portions of the city of
Lansing, and a foster care facility located in Windsor Township. The plant discharges final treated effluent to the Grand River, while
residuals, or “leftovers”, of the wastewater treatment process are treated and stabilized so that they can be safely returned to the
environment as nutrient-rich biosolids commonly used as a soil supplement.
In October 2007, construction began on an innovative first-of-a-kind digester project that incorporates heat recovery and electrical
power generation while producing the highest quality biosolids. The heat and energy component of the system will reduce the
demand for natural gas and electricity, yielding an annual cost savings of more than $75,000. The new digesters should go online by
this summer.
