Feeding Jinan’s heating network with heat from wastewater

ongoing

AFD is supporting this project aimed at building decentralized collective heating systems by recovering heat from treated effluent from two water treatment plants. This will provide heating for residential buildings and cooling systems for commercial buildings in two districts of Jinan. The project will cover a total area of approximately 3 million m2.In Da Wei district, a new power station will replace the current heating system, which is fueled by a coal-fired cogeneration power plant. In Hua Shan district, north-east of the city, 21 energy stations and 42 water-to-water heat pump units will recover heat from the wastewater from the local water treatment plant. The project also includes the construction of a 7.7-km pipe network, the installation of a 36-km heating network and automation of the network.This project follows on from a first program supported by AFD in Jinan from 2011, which had enabled to renovate and improve the energy performance of the city's urban heating networks.
