Standby Generators For Emergency Power

Many of you are aware of the importance of standby generators in everyday life. Standby generators, usually diesel generators are used as substitutes in the loss of the mains electrical supply. Emergency or backup generators are used worldwide in a variety of applications such as commercial facilities, hospitals, water treatment plants and other domestic applications. Today, we are going to explore the importance of emergency power in water treatment plants.

You probably know that the water we use daily is treated prior to being supplied to us. It is necessary to do this because it improves the quality of the water so that we can accept it for a specific end-use. The end user may be drinking, washing, cooking, cooling, irrigation and other industrial uses. Water treatment plants are used to treat the water, where they remove the contaminants and other harmful impurities from it. The plants are supplied from man-made water reservoirs, lakes and rivers.

The water is processed in the following manner to remove the impure solids, bacteria, algae, viruses etc. that may be present in it:

• Pre-Chlorination
• Aeration
• Coagulation for Flocculation
• Sedimentation
• Filtration
• Disinfection

Around the world, many cities, find that wastewater treatment plants and producing water for drinking are typically their largest energy consumers. In some cases 30-40% of the cities’ energy consumption is used by water treatment processes alone.

So, you may ask the question, “Where do generator come into play?” The answer is pretty simple. The consumption facilities of water treatment plants are often backed up by diesel generators!

Loss Occurred Because of Unavailability of Backup Generators:

• If the power grid fails and an emergency generator is not installed, then the water pumps stop, the water treatments tanks are empty and there will be no water distribution.

• The flocculation stage of the treatment will stop. This takes place in a flocculation basin which includes a large paddle which has to rotate at specific speeds, requiring electrical energy to function.

• The water pipes are pressurized by large electric pumps with treated water. The pump’s suction side is connected to the tank containing the treated water. If there is no power to supply the pump’s electric motor, the water system will fail to maintain pressure. This will lead to a loss of water in the utility system. This will affect human life in the following ways:

1. No water for drinking, cooking and other domestic usages.
2. No water facility for fire safety systems.
3. Lack of industrial water for the supply of machines.
4. Lack of water for fire extinguishing efforts.


Another way that may affect the production of water is security. Many water treatment facilities use security systems to alert officials and staff in the case of any theft or terrorist activity. If there is no backup generator, the security systems will fail to alert the company of threats to life and property.


We hope now you understand the importance of standby diesel generators in water treatment plants. There are many other industrial applications that rely on electricity and may need back-up power in the event of a mains failure.
