Himoinsa has installed a standby generator unit capable of providing 48 hours of uninterrupted backup power for a municipal wastewater treatment plant in the town of Ali Mendjeli, Algeria.
The facility purifies 4,200 cubic metres of water per hour, and is responsible for serving a population of 260,000 people, while a large proportion of the purified water is reused for agricultural irrigation.
The standby power unit is a Himoinsa HTW-1530 T5 generator set fitted with a Mitsubishi engine, and capable of supplying up to 1660kVA of stand-by power in case of mains power failure at the plant.
The unit is linked up to a large external tank with a 20,000-litre capacity, which is what gives the generator its ability to ensure the continuity of the plant’s operation for the span of 48 hours.
To ensure that the process of refuelling the genset from the tank can work smoothly during this time, a redundant transfer system has also been installed.
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 is being overseen on behalf of the Algerian Ministry of the Environment by the diversified Spanish-Algerian company SICE, and part of Spain’s ACS Group.
Javier Vecino, hydraulic infrastructure manager at SICE, noted: “We chose Himoinsa because of how they compared in technical and economic terms. We needed a first-class generator, with a combustion engine, and local service that was also very much appreciated by the customer.”
Azeddine Yekhlef, regional director for the Ministry, added: “It’s very important to have a specialised and professional local service to carry out maintenance and repairs on the generator sets. The machines work constantly, so we need them to be in perfect condition when they are required.”
