Frequently Asked Questions

How does a sewage treatment plant work?

sewage treatment plant works works by breaking down solid waste to produce a more environmentally friendly effluent. A sewage treatment plant uses your household or business wastewater combined with sewage and is placed in a primary tank, where the solids and liquids disperse. The resulting liquor flows into the biozone chamber where a pump airates the waste and encourages friendly bacteria to condense the organic matter. The result is a 95% clean fluid which can then be legally dispersed into local soakaways or ditches, subject to the relevant environmental approvals from your local authority. 

How long does it take to build a sewage treatment plant?

To build a sewage treatment plant really varies according to the scale and complexity of the project. But a normal domestic sewage treatment plant of an average size can be placed and laid in the ground within 7-10 days.

How does a Septic Tank differ from a Sewage Treatment Plant?

It is a common misconception that a Septic Tank is the same as a Sewage Treatment Plant, but this is not the case. 
There a few fundamental differences between the septic plant and a Sewage Treatment Plant. 

1. Septic Tanks waste needs further treatment before it can be safely and legally discharged. The waste must go to the next stage of processing  with natural aerobic soil bacteria.

2. Septic tanks do not use electricity and are self contained in this way. 

3. Septic tanks need to be emptied once a year. 

So the most effective for the treatment of Sewage and waste water is through the use of a Sewage Treatment Plant. Sewage treatment plant emits a clean, non-polluting effluent which can be discharged directly to a stream or watercourse. 

Do Sewage Treatment Plants require electricity to operate?

Yes, Sewage Treatment Plants require electricity to operate. There are various valves and motors within the self contained plant itself that are required for the safe processing and safe removal of the effluent.

Do I need a licence for the operation of a Sewage Treatment Plant?

No you do not need a licence to operate the Sewage Treatment Plant, but you will need local authority planning and there is an environment permit that is required. 
At CJ Sewage Treatment we can get the permissions that are required to carry out this work.
