Standby generator installed at Algerian waste water plant

November 14, 2017


Algeria’s government has installed a standby generator with an uninterrupted running time of 48 hours at a waste water treatment facility in the northeast of the country.



The HTW-1530 T5 generator, fitted with a Mitsubishi engine, was supplied by Himoinsa— part of Japan’s Yanmar group. The generator is capable of supplying up to 1660kVA of stand-by power to the facility in the city of Ali Mendjeli, Constantine, in the event of a mains failure.


The facility purifies 4,200 cubic metres of water an hour and serves a population of 260,000. A large proportion of the purified water is reused for agricultural irrigation.


An external 20,000-litre capacity fuel tank allows the generator to run for up to 48 hours if necessary, Himoinsa said.


“To ensure it works smoothly during this time, a redundant transfer system has been installed to transfer fuel from the external tank to the generator,” Himoinsa said. “The pumps have been programmed with a start-up delay, so that if the first pump does not start-up, the second is already full and ready to transfer fuel to the generator.”


The project was managed by Spanish-Algerian company SICE— part of Spanish infrastructure development firm the ACS Group— on behalf of Algeria’s environment ministry.
