• Smaller home system are almost similar to septic tanks,  but are slightly more expensive. However, in the long run you save your money with regards to recycling your water as well as space usage as you don’t need a soak pit and in other situations constant exhausting.


  • The larger the system the less cost per housing unit. City council charges 75% of the water bill for sewer connection. Our systems always come lower than this when all operation and maintenance is considered.

  • Similar to the space requirements for a septic tank

  • Commercial Projects – If we are doing all the works including civil then approximately 4 months
  • Residential Projects – If we are doing all the works including civil then approximately 1 month
  • If a main contractor is doing the civil works- Then our completion date is dependent on when they finish their part of the work

  • CESP provides 1-year end user training & maintenance. We have a team dedicated to maintenance who handle calls and can retrain the caretakers/grounds staff with basic monitoring techniques to ensure efficiency of the system .

No. Because of these 2 main reasons:

  • Space requirement – To have this kind of system you need a very large piece of land to construct several chambers so as to provide enough time for the waste in the water to naturally breakdown before moving to the next stage, i.e its like building multiple septic tanks connected with gravitational flow between them. At CESP we understand that space is of the essence and in development every sqft is a crucial resource and thus we strive to make the most use of it.
  • Tends to be Costly – The alternative source of power is use of a solar system which is expensive when you consider how many batteries you require to run a larger system say 24,000 GPD. It’s cheaper to connect to Grid power.

  • The plant will remain okay for 48 hours as the bacteria is still alive. After this an alternative source needs to be sought to run the blowers to pump in air. All our systems are aerobic thus air is a key ingredient.

No it is not possible because:

  • Psychologically, people living within the building would not like to imagine any chance of their direct use water passing through the same pipes as the effluent.
  • For redundancy sake in case there is a problem with one system the other can work.
  • NEMA standards don’t allow the effluent to be used in the showers as this could be a point of risk in their view.

  • This indicates a situation where the pH is imbalanced. It could be due to chemicals including harsh detergents flushed /washed down the system or too much chlorine used to disinfect the effluent, that result in raising of the system’s pH.
  • The solution is to test the in-fluent and effluent to discover the level of alkalinity/acidity then use a small dosing tank to level the pH.
