Our fish farms transform neglected waste stabilization ponds (WSPs) into thriving, multi-use facilities.
The Problem
Waste stabilization ponds (WSPs) entail a series of four to five ponds that make up an effective, low-cost means of treating wastewater. But in developing countries their performance often suffers due to limited financial and human resources, and lax enforcement of environmental regulations.
If neglected, the ponds stop functioning. They become overgrown, sludge builds up, pipes get blocked, and the water exiting the plant is harmful to human health and the environment.
Our Solution
Through fish farming, we transform WSPs that are suffering from lack of maintenance. We do this by raising fish in the final (maturation) ponds of the system, where the wastewater is already partially treated.
As fish farmers, we have every incentive to ensure that the WSPs we occupy are perfectly maintained and operating. If not, our fish are subject to death or disease, and may not pass WE and international standards for human consumption.
Our Impact
We’ve found a way to align a profit motive with the incentives to keep waste stabilization ponds in optimal condition.
This way our fish farms are improving the environment and public health.
