On Wednesday, a swimming pool in Paris launched a new heating system that uses heat recovered from the sewer to reduce costs and reduce carbon emissions.
The Aspirant Dunand swimming pool in Paris area 14 is the latest in a series of public buildings in France, using heat pumps to recover the remaining heat from showers, dishwashers and washing machines in sewage pipes.
Suez waste and water group in France owns 30-
A one-year installation contract has run more than a dozen of these heating systems across the country, including the Annemasse near the Paris suburb of Levallois and the Swiss border, as well as the school\'s swimming pools, apartments and administrative buildings.
It builds three to four new facilities each year.
The potential is enormous.
We can recover heat wherever there is a sewer . \"
France has a sewage network of about 400,000 kilometers, where the water temperature is usually between 13 degrees Celsius (55. 4°F)
20 degrees in winter (68°F)in summer.
Suez has a stainless steel lining inside the sewage pipe, which can adjust the temperature of 4 to 8 degrees and lift it to about 50 degrees for space heaters or hot water.
This technology is similar to low-
Temperature Geothermal energy sources have been widely used in some countries to heat individual homes.
Suez said the cost of swimming pools ranged from 200,000 euros to 1 million euros ($1. 12 million)
For an apartment building, these projects pay for 8 to 9 years without subsidies and normal energy prices.
Camus said the Aspirant Dunand unit accounted for nearly half of the pool\'s energy consumption.
Paris aims to reduce greenhouse gas emissions by 2020, increase the share of renewable energy in government energy use to 30%, and make better use of its 2,400 km-kilometer sewage treatment network. ($1 = 0. 8912 euros)(
