Commercial Sewage Treatment Plants

The majority of business are served by main drainage but for small fraction of business off mains drainage is the only solution. If your business is situated in rural location it’s more than likely you will need measures in place for new off mains drainage system suitable to your business requirements.

The strength of the sewage entering the package sewage treatment plant should be considered when sizing the off mains drainage system. The under sizing of commercial sewage treatment plant is common mistake and honest approach with future business growth will enable us to size your system correctly. We would consider the usage in every aspect to size the sewage treatment plant complying to ‘British water flows and loads-Part 4.’ It would enable us to calculate the right population equivalent for your requirements.

Commercial Sewage Treatment Plants Process 

All sewage treatment plants are based on the same principle: to create the right environment for aerobic bacteria to be produced. The addition or presence of air creates microorganisms to break down the sewage, with various treatment and settlement zones. The effluent quality from most leading manufacturers is 95% or above clean water through the various stages of sewage treatment. The effluent from sewage treatment plant can discharge to watercourse or discharge to a drainage field (soakaway)  subject to Environment Agency approval.
