SewTreat Delivers 80 KLPD Potable Water Treatment Solution to Secure Water Independence for Carletonville Commercial Hub

SewTreat, a leader in modular water and wastewater treatment solutions, has commissioned a cutting-edge 80,000 litres per day potable water treatment plant in Carletonville, South Africa. The installation provides a critical lifeline for a major commercial center facing unreliable municipal supply, delivering safe, SANS 241-compliant drinking water directly from a borehole source.

The facility integrates advanced multi-stage filtration and disinfection technologies, including Activated Filter Media (AFM), Granular Activated Carbon (GAC), and DMI filtration, ensuring superior removal of turbidity, iron, and manganese while producing water suitable for human consumption and other non-potable uses.

A Turnkey Water Security Solution

Key features of the Carletonville plant include:

• 80 KLPD treatment capacity with 6,667 litres/hour flow rate.
• Full modular design housed in a 6-meter containerized unit for rapid deployment and easy maintenance.
• 37 KL raw water storage and 72 KL treated water holding capacity, ensuring 24-hour autonomy.
• Smart PLC-based control system with GSM connectivity for real-time monitoring and operational oversight.
• Seamless municipal bypass line for resilience during peak demand or system maintenance.

SewTreat’s scope covered design, construction, installation, commissioning, and training, ensuring an end-to-end solution tailored to site-specific conditions.

Sustainability and Cost Impact

By shifting to borehole-sourced, onsite treatment, the center achieves:

• 84% reduction in municipal water costs, cutting rates from R60.52 to R4.00 per kilolitre.
• Annual savings exceeding R1.2 million, with a rapid payback period of just 1.23 years.
• Long-term savings projected at R19.1 million over 10 years.
• Significant environmental benefit through reduced reliance on municipal infrastructure and improved water stewardship.

The plant positions Carletonville as a model for commercial water security, demonstrating how decentralized treatment can future-proof operations against rising tariffs and resource scarcity.
