This centralized system caters for a camp of 20 guests, 10 members of management and 30 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 2 x 5000L final holdings tanks in series followed by 3 x ECOROCK-5000 units in parallel, allowing up to 15000L of water to be treated on a daily basis.

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 2 x 5000L final holdings tanks in series followed by 3 x ECOROCK-5000 units in parallel, allowing up to 15000L of water to be treated on a daily basis.

Final effluent is sprayed into a set of sprinklers.

Containerized 60 P.E. system in the Okavango Delta (staff village)

This system is featured on BIOROCK’s official webpage – see below

The system was installed in March 2016. The containerized solution meant that transport of the units to site was easier. In future, some of the plumbing could even be done in town beforehand, especially with the new design of the ECOROCK tanks. Ideally, the primary tanks would have been housed in a container as well, but there was not enough space for the required primary tank a capacity.

As the staff village is separate from the main camp and main power supply, the need for little power (i.e. sump pumps only) was a big selling factor. The modular nature of the BIOROCK system lends its self to be containerized and sent to site. In addition, all structures built in the Okavango Delta need to be of a semi-permanent nature. As such, no concrete structures are allowed (with very few exceptions, such as fuel bunds). The reasoning behind this is that these natural areas should be able to rehabilitate easily if the camp was to be moved or decommissioned. Any other treatment plant would not allow this easy removal.

Commercial 30 P.E. system in Maun

This system was installed in Maun to save on the constant need to evacuate the conservancies on the property (by honeysucker). This was needing to be done every two weeks. The BIOROCK effluent now is used to irrigate the gardens.
