Sewage Treatment
Sewage Treatment
Are you in a remote area, away from a town or city? Are you off the municipal sewer line with multiple people using your ablution facilities?
What happens to your sewage & waste water? How do you make sure it does not pose a risk to your local environment? Left untreated, it can be hazardous to health, spreading harmful pathogens that endanger human life, plants and animals as well as the underground water table.
Wherever you may be, you can rely on WATERfirst to create a Waste Water Treatment Plant that works for you.

Waste Water Treatment Plant (WWTP)
At WATERfirst we provide a Waste Water Treatment Plant (WWTP) that, using a biological process, eradicates contaminants and impurities from the wastewater, which ensures a clean, safe water re-entering the environment.
What is classified as Waste water and suitable for processing through a WWTP?
Water used in your home or business, such as toilet water, baths & showers and laundry.
What waste water cannot enter the WWTP?
Water from kitchens must enter through a FOG trap to hold back fats, oils and grease before entering the WWTP. The use of very strong chemicals & detergents may hinder the biological process of the WWTP.
- Tailor made Waste Water Treatment Plants to suit your specific needs
- Eco friendly biological process
- Units installed in convenient places & out of sight
- Sealed units ensure that no unpleasant sewage smells occur
- Expandable modular units if your water treatment demands increase
- Treated water can safely be reused for irrigation purposes
- Commitment to after sales service
- Maintenance of WWTP plans

The WWTP process:
Septic Tanks
The waste water starts its journey being flushed down the various pipelines into septic tanks. Here it is compartmentalised keeping the solids back allowing for the waste water liquid to continue the journey through to the WWTP.
Pretreatment Tanks
The water gets pumped into pretreatment tanks which allows for settling time and the start of the anaerobic treatment process of the waste water.
Bioreactors
Continuing its journey through the waste water treatment process, the waste water enters into the bioreactors at the correct flow rate. This is set according to the high peak flow of water usage and enters into the bioreactors at a perfect rate for the treatment process to occur.
Beneficial Microorganisms
The heart of the system are the bioreactors, they house the beneficial microorganisms that convert the organic and inorganic compounds, such as Ammonia to Nitrates into reusable water that is safe to use for irrigation purposes. Oxygen plays an essential part in keeping the microorganisms alive and relies on a source of electricity to provide a constant and abundant flow of oxygen via the pumps.
Clarifier
The water then flows through a clarifier which will desludge at various intervals removing the carry over sludge and pumping it back to the primary stage of the treatment process.
Chlorine Dispenser
A Chlorine dispenser ensures that any remaining pathogens in the contact chamber are annihilated. Ozone and UV disinfection are alternative options.
Safe Water
Safe water is released into the environment.
Maintenance
As with all working equipment, maintenance plays an essential part in keeping the system working properly. We offer maintenance plans that goes through a check list and tests various parameters such as pH, ammonia, dissolved oxygen and free chlorine to make sure the system is correctly functioning and assists in any irregularities being addressed timeously.
Frequently Asked Questions
How much does a domestic sewage treatment plant cost?
This depends on the volume of sewage being treated, a fully installed domestic unit will cost you anything from ZAR90,000 upwards.
What is the best treatment for sewage?
At Waterfirst, we believe that nature has all the answers. Working with natural microorganisms to treat sewage, ensures no harm is done to the environment or to our precious water resources.
How long does it take for sewage to be treated?
The process takes between 16 – 20 hours.
What are the disadvantages of a sewage treatment plant?
These Sewage Treatment Plants are fairly expensive to install. However, if looked after properly, these durable systems will last a long time.
How often does a sewage treatment plant need emptying?
The Sewage Treatment Plant , if looked after correctly, will only need to be flushed approximately every 10 years. Septic tanks, (remembering that they must be sized correctly) will need the solids removed between 10 – 15 years.
How long does it take to install a sewage treatment plant?
Waterfirst Sewage Treatment Plants are custom made, the preparation can take up to 10 days depending on the amount of waste water that is going to be treated. On site installation takes between 5 – 10 working days.
How do you treat domestic sewage water?
It goes through a series of anaerobic and aerobic processes that use beneficial microorganisms to treat the waste water.
What's the difference between a septic tank and a sewage treatment plant?
A septic tank is a tank which holds the sewage from your toilet system and the waste water from your home. The excess water gets drained out into a soakaway system. A Sewage Treatment Plant processes the waste water that comes out of the septic tank and treats it biologically making it safe for release into the environment.
What kills sewage bacteria?
Bacteria can be killed off by the use of very strong chemical products. Over time, fats, oils and grease can clog up the pipework and smother the bacteria (a F.O.G. trap installed at your kitchen prevents the fat build up). A lack of oxygen in the Sewage Treatment Plant will also kill off the beneficial microorganisms.
Where does water go after sewage treatment?
This water is safe for reuse as irrigation, or for release into the environment.
Will sewage smell go away?
The STP itself is well sealed and will not smell if it is functioning properly. Interestingly enough, if you open one of the chambers where the sewage is being treated, you will get a slightly damp earthy smell which is not unpleasant at all.
What materials cannot be removed from wastewater?
The Sewage Treatment Plants are biological living systems designed to treat sewage and non-invasive cleaning products. Heavy metals & plastics (microbeads) cannot be removed through this biological process.
Does a sewage treatment plant need a soakaway?
A soakaway is not needed.
Can you drink the water leaving the Waste Water Treatment Plant?
If you are wanting to use this water for drinking purposes, it would have to go through a Reverse Osmosis System.
Do I need to add any bacteria into the Waste Water treatment Plant on an on-going bases?
Once the Sewage Treatment Plant is installed, there is no need to add in any further biological microorganisms.
