50+ Person Commercial Sewage Treatment Plant

Commercial sewage treatment plants are large-scale waste removal systems for commercial properties that are either in a rural area or can’t be connected to the public sewage network. As they are entirely independent, they use a process that breaks down the waste into a clean product that can be directly discharged directly into the environment without harming the local habitat.

They function in the same way as domestic sewage treatment plants, but are designed to cope with a much higher volume of sewage. Commercial sewage treatment plants have a motor, powered by a generator or other electrical source, that circulates air within the system. Naturally occurring bacteria use this air to break down the wastewater in the system. This destroys the harmful substances in the waste, and, after several stages of treatment, the wastewater is clean enough to be pumped into the local environment.

Initially the waste goes through a pre-treatment stage, that removes large objects and solids. The waste is then pumped into a settlement zone, where liquids rise to the top and larger substances collect at the bottom thanks to their different densities. Bacteria starts to break down harmful substances and the sludge that forms at the foot of the tank is periodically removed. The remaining liquid is then ‘cleaned’ by a process known as ‘biological treatment’, where aerobic bacteria use the oxygen circulated by the motor to break down more harmful substances. Finally, the wastewater goes through a final round of cleansing to kill any remaining harmful substances that remain. This may involve chemicals to ensure the water is as clean as possible before it’s discharged. 

There are many reasons why you may need a commercial sewage treatment plant installed. If your business is in a rural location, you may be too far away to connect to the main public sewer system, or perhaps your access to the public sewers is blocked by a railway line. Commercial sewage treatment plants are also eco-friendly, so if your business is looking to become more eco-friendly, a commercial sewage system could be for you. The wastewater in a commercial sewage treatment plant is treated before being discharged, so there is no harm to the environment. They are also cost-effective. After the initial installation costs, commercial sewage treatment plants save money on bills paid to your local authority, making them an attractive long-term investment for many businesses. Commercial wastewater treatment plants can be set up quickly and easily. There are minimal odours and disruption to the running of a property and, if your system is properly maintained with regular servicing, your system will function for a long time.

Commercial sewage treatment plants function in much the same way as domestic sewage treatment plants but are designed to cope with a much higher volume of sewage. Commercial sewage treatment plants can service business and commercial properties where 50 or more people go to work. In contrast, domestic sewage treatment plants would usually only deal with household waste from up to four or five people.

You’ll want to choose a commercial sewage treatment system based on the size of the premises and the number of people using the facilities. But don’t go too small! It might save you money in the short term to buy a smaller system, but if you need to upgrade to a larger system in the future it will cost you.

It is important to keep any sewage treatment plant properly serviced and maintained, but with commercial sewage treatment plants professional maintenance may be required more often and require specialty maintenance to ensure everything is working as it should.

Sewage treatment plants are robust and effective and offer many benefits over some other methods of sewage treatment such as septic tanks and cesspits. But how much does a commercial sewage treatment plant cost? There are several costs to consider.

The cost of installing your commercial sewage treatment plant will depend on whether you’re installing a brand new system or upgrading an existing one, as well as which plant you have chosen and where the plant is being installed. 

Annual service

You’ll need an annual service to ensure the ongoing performance of your commercial sewage treatment plant. The cost will depend on your equipment and location.

Emptying

Sewage treatment plants need to be periodically ‘de-sludged’.
