Energy Recovery in Water Service Plants

In 2010 some studies of the possibilities and technologies for energy recovery in water service plants were begun. The first feasibility study was drafted for energy recovery inside our purification plant in Bologna, using high-efficiency screw pumps developed by the Loccioni Group. In 2011, two other studies were launched: the first concerns energy recovery from the mains water supply using In Pipe Turbine (IPT) or Pump As Turbine (PAT) systems; the second project involves heat recovery from mains water using low enthalpy heat pump systems.

Based on these studies, following further data analyses and field tests carried out in the first half of 2012, a decision was made to continue the pre-feasibility study of an application at a water pressure reducing station in Bologna, to optimise possible energy recovery.
