Centralized 90 P.E. wastewater treatment plant for a remote safari camp in the Okavango Delta


This centralized system caters for a camp of 28 guests, 12 members of management and 35 staff members. The reticulation of waste from guest units, the camp kitchen and laundry and the staff village is achieved through septic tanks and pump tanks at these areas.

The main treatment plant consists of two 5000L final holding tanks in series followed by three ECOROCK-5000 units in parallel, allowing up to 15000L of water to be treated on a daily basis. Final effluent is treated by an inline chlorinator and sprayed into a set of sprinklers.

This treatment plant requires only 250W (to power the final submersible pump) and uses  less than 1kWh/24 hours.

ECOROCK- How does it work?

a.jpgThe ECOROCK® units are packaged domestic sewage treatment plants (STP) based on the trickling filter process and comprising two stages. The raw sewage first enters a primary tank (or existing septic tank) to provide primary separation of water and solids and breakdown of organic solids by means of anaerobic digestions (or fermentation). The solids-free sewage then passes through an effluent filter and into the ECOROCK unit, which incorporates the aerobic filtration process comprising layers of unique ECOROCK filtration media.

The aeration of the primary tank (optional) and ECOROCK units is both executed by natural draft. The final treated discharge from the ECOROCK is either discharged by gravity or (more typically) collected in a pump well, where a small automatic submersible pump is utilized to lift the final effluent directly to a sprinkler or holding tank for further use.
