Off-grid Sustainable Waste Management Meets Eco-Irrigation.
Overview
The Olifantsfontein Resource Facility, a leading Waste Management Facility in Olifantsfontein, Midrand, required a customised wastewater treatment solution. Calcamite was tasked with the design and supply of a system that not only treats wastewater but also repurposes it to water the facility’s gardens, reflecting the company’s commitment to environmental sustainability.
Requirements
The facility, equipped with on-site ablutions and a kitchen, lacked a connection to municipal sewer services. A new, environmentally friendly wastewater treatment plant (WWTP) was needed to manage the facility’s waste output.
Solution
Calcamite implemented a comprehensive WWTP featuring septic tanks sized for the necessary retention time and a Bio-reactor with fixed film media. This setup provided a surface for biomass attachment and aeration, allowing aerobic bacteria to break down the organic matter.
The final disinfection stage, using chlorine, ensured the treated effluent was free from pathogenic bacteria, making it safe for irrigation use.
Conclusion
At Olifantsfontein Resource Centre, Calcamite’s tailored wastewater treatment system has set a precedent for waste management facilities. By transforming wastewater into a resource for irrigation, the centre epitomizes the synergy between industrial activity and ecological conservation.
The project not only aligns with the centre’s green ethos but also represents a vital step in preserving our most precious resource – water.
