Clarus Environmental’s Fusion Series Treatment Systems are drop-in wastewater treatment units designed for use in decentralized applications where the effluent quality needs to meet or exceed DWS standards.

The first Fusion was installed in Franschhoek in 2010 and today more than 200 units have been installed in 8 different countries on the African continent.

The Fusion is designed for use in residential, new sustainable property development, commercial, and community applications.  Fusion is available in a variety of treatment capacities, from 1,700 lpd to 15,000 lpd.

The Fusion’s unique design enables it to be installed without a pretreatment tank, making it ideal for use on sites where space is limited.  Effluent disposal options include conventional trenches, dams, irrigation or direct discharge.

Fusion’s modular flexibility allows to increasing the capacity treating any volumes required.


“The Clarus Fusion is designed to be used both in urban areas and remote locations.”

By using the Clarus Fusion to treat both black and grey water, every community in the country can have access to flush toilets, without using a single drop of potable water. 

Treated water from the Fusion can be used for toilet flushing.  Where space is limited, the Fusion can be installed in walk ways or public open spaces. 

Excess treated water can be used for irrigation purposes. Fusion is the only plant that can handle from one household to communities, from informal settlements to high income estates, from in-urban use to the most remote areas.

Basic Layout of the Claris Fusion® system 


  1.    When a toilet is flushed, the booster pump will start and deliver water from the tank to the toilet under pressure. A small amount of chlorine is dosed         into the system, ensuring the water in the toilet is bacteria free.
  2.    As the tank level drops, a float switch in the tank will demand water from LS4. The pump will start and transfer water to the storage tank.
  3.    As the level in LS4 drops, it will demand raw sewage from LS1.
  4.    The pump at LS1 will start and feed raw sewage to the Clarus Fusion WWTP, where it is treated and gravity flows to LS4 via a UV for sterilization.
  5.    If LS1 is full and there is no demand from LS4, the excess sewage gravity overflows to the municipal sewer.
  6.    If there is a high level in LS4, the backup pump starts and waste the excess treated effluent to the municipal sewer.
  7.    There is a municipal backup to fill the storage tank if needed.

    Do’s and Don’ts




  • Service plant every 6 months & send service report to JDCH20
  • Replace UV lamp every year
  • Replace Blower Diafragm & Air filter every four years
  • Use septic tank friendly detergents & chemicals 



  • Use harmful chemicals, i.e. Bleaches, chlorines, anti-bacterial sanitisers, detergents & -soap. It will kill the bacteria in any biological plant
  • Flush inorganic matter down the drain
  • Flush paper hand towels or newspaper down the drain. These kinds of paper take forever to degrade and may cause blockages in the sewer system
  • Introduce petrol / oil / grease / engine cleaner into the system Flush paint / thinners down the sewer line
  • Overload the system
