A Paris swimming pool has inaugurated a heating system using warmth recovered from sewers in an attempt to cut costs and reduce carbon emissions. They are also in use in schools, apartment blocks and administrative buildings, and Suez is installing three to four new systems a year. Wherever there are sewers, we can recover heat,” said Bertrand Camus, the head of Suez water in France. The technology is similar to low-temperature geothermal energy, already widely used in some countries to heat individual homes. Paris aims to reduce its greenhouse gas emissions, boost the share of renewables in the administration’s energy use to 30% by 2020 and make better use of its sewage network.
