Sewage System Helpful Guides 

We've compiled a list of helpful blogs that should hopefully answer any questions or purchasing queries that you may have:


How do sewage treatment plants work?

Eliminate contaminents from waste water by circulating air to allow for bacteria growth

Sewage treatment plants work by eliminating contaminents from wastewater & household sewage by circulating air within the unit to prompt bacterial growth, which breaks down the sewage. These systems make for cleaner and more environmentally friendly efluent. Please see below a step by step breakdown of how a Sewer Treatment Plant operates:

  • Sewage travels into the first chamber of the plant. Within this chamber, oils and greases will be seperated and will float to the top of the tank, with the solids settling on the bottom.
  • Next, the liquids are moved into a second chamber where air will be pumped into it. This help to grow the level of bacteria within the sewage, which leads to the break down of contaminants in the liquid.
  • The liquid will then be moved into a final (settlement) tank. Here the remaining solids sink to the bottom of the tank, and the contents are then discharged.

Are there any regulations to be aware of?

Must be EN 12566-3 2005 certified

In order to comply with regulations, UK sewage treatment plants must be EN 12566-3 2005 certified. In addition, you should always have your sewage system installed by a qualified professional. You will also need to check your local guidelines to understand whether you will need planning permission to install.

Why should I get a sewage treatment plant?

There are a handful of benefits to owning a treatment plant. These are:

  • Long lifespan: The expected lifespan for a treatment plant is 40 - 50 years.
  • Low maintenance and running costs: These plants use very little electricity leading to low running costs. They also typically only require maintenance once per year.
  • Environmentally friendly: The filtered water (final product) is safe to be dispensed into drainage fields and various bodies of water, as long as it does not harm wildlife or go against local environmental guidelines.

How close to a house can a sewer treatment plant be?

Minimum of 7 metres from building foundations

According to regulations surrounding sewer treatment plants they must be a minimum of seven metres away from any building foundations, and further than 10 metres away from a watercourse.

How to maintain a sewage treatment plant?

Quality tests, chemical level monitoring & equipment inspections

Maintaining a treatment plant involves testing the quality of the influent and effluent, monitoring chemical levels, implementing proactive cleaning and lubrication schedules, inspecting the equipment and pipes on a regular basis, and training on safety procedures. Answer alarms as soon as possible, and maintain documentation for compliance and troubleshooting.

It's also important to 'de sludge' the tank at least once a year to prevent buildup. Cheaper tanks may need to be de sludged more frequently then once per year.

Do you need to empty a sewage treatment plant?

Yes, recommended every 6 months

In order to keep solids from building up in a sewage treatment plant, periodic sludge removal is required. Sludge is created when solid waste eventually sinks to the bottom of treatment tanks. This sludge can cause unpleasant odours and lower the plant's efficiency if left behind. Frequent sludge emptying and disposal are necessary to keep the plant operating efficiently and provide efficient wastewater treatment.

What to know before installing?

When installing a treatment plant, there are a couple of things that need consideration before you can install your system. These consist of acquiring planning permission and obtaining building regulations approval.

What's the structure of a sewage treatment plant?

Sewer treatment plants' structure consist of 2 chambers. 

Chamber 1 is where the liquid is seperated and the solids sink to the bottom of the tank.

Chamber 2 contains a motor within the water which creates air, which then leads to the break down of the sewage.

Once the process inside Chamber 2 is complete, the finalised liquid will be clean enough to be distributed via a drainage field or watercourse.

What is the lifespan of a sewage treatment plant?

Between 40 - 50 years 

The typical lifespan of a wastewater treatment plant is between 40 and 50 years, while the equipment used for treatment usually has a 15 to 20 year lifespan.
