Full Water Reuse Systems

What Sewtreat Does

SewTreat designs and implements full water reuse systems for facilities where boreholes, rivers, or rainwater harvesting are not viable. These advanced systems treat wastewater to potable standards, allowing complete on-site water recovery, reuse, and independence from municipal supply.

Our Scope Includes

On-site wastewater recovery and treatment to drinking water standards (SANS 241)

Complete process design, including biological treatment, filtration, and reverse osmosis (RO)

Integration into existing facility infrastructure and control systems

Full automation and remote monitoring via SewTreat Live

Turnkey design, manufacture, and commissioning

Ideal Applications

Full reuse systems are ideal for:

Facilities without access to borehole water or alternative sources such as council.

Facilities located in urban areas such as Johannesburg, Pretoria, and Cape Town where water tariffs are high and boreholes are not permitted.

Commercial and industrial operations consuming more than 30 KL per day, looking to significantly reduce water costs.

Sites requiring water security, ensuring continuous operation during municipal supply failures or restrictions.

Typical Process

SewTreat’s full reuse systems recover and treat all domestic wastewater generated on-site through a multi-stage treatment process that ensures compliance, efficiency, and safety:

Biological Treatment: Removes organic matter, ammonia, and nutrients through advanced aerobic and anoxic processes.

Filtration: AFM (Activated Filter Media) and GAC (Granular Activated Carbon) filtration polish the effluent to remove fine particulates, colour, and residual organics.

Reverse Osmosis (RO): Produces high-purity water meeting potable standards, ideal for reuse across the facility.

Disinfection: Ensures pathogen-free water for safe, consistent operation.

By recycling 100% of on-site wastewater, SewTreat’s systems provide complete water independence, significant cost savings, and enhanced operational security.
