Rising municipal water tariffs are creating more than just higher utility bills.

They’re increasing operational pressure, reducing margins, and exposing businesses to long-term risk.

For commercial and industrial facilities, water resilience is no longer optional — it’s a business strategy.

At SEWTREAT, we help businesses:
💧 Reduce freshwater dependence
♻️ Recover and reuse water
📉 Lower operational costs
🛡️ Improve water security

Don’t just react. Act before tariffs hit harder.

At SEWTREAT, we help businesses take control through:
💧 Borehole treatment systems
♻️ Water and wastewater treatment
🏭 Process-water recovery
📉 Demand reduction strategies

Proud to showcase another successful wastewater infrastructure project delivered by Sewtreat.

We recently completed the design, construction, installation and commissioning of a 60kL/day below-ground wastewater treatment plant for Genet Mineral Processing in Ogies, Mpumalanga.

This fully automated system treats wastewater to DWA general discharge standards, while also enabling water reuse for irrigation - supporting both environmental compliance and sustainable water management.

Built with advanced PLC automation and fully integrated with Sewtreat’s FlowSense remote monitoring platform, the plant delivers intelligent process control, real-time performance monitoring, improved operational efficiency and reduced maintenance risk.

Our below-ground civil construction approach provides a durable, space-efficient and visually integrated solution tailored for demanding industrial environments.

At Sewtreat, we remain committed to engineering innovative wastewater solutions that combine reliability, sustainability and smart technology.

Sewtreat - engineering the future of water.

Water security isn’t just an environmental issue — it’s a business necessity.

Reliable access to water protects operations, reduces risk, lowers long-term costs, and ensures compliance in an increasingly resource-stressed world.

From operational continuity to sustainability, investing in water security means investing in resilience.

💧 Future-ready businesses don’t leave water to chance — they secure it.

What happens when a hotel runs out of water?

In South Africa, that’s no longer a hypothetical question — it’s a growing risk.

Sewtreat recently designed and implemented a backup water system for Town Lodge Roodepoort, part of the group, ensuring a reliable alternative when municipal supply is under pressure.

With on-site storage, automated system functionality, and off-site monitoring features, the solution is built for resilience — supporting uninterrupted operations when it matters most.

Because water security isn’t optional anymore — it’s essential.

Most people would never guess what’s happening inside a plant like this.

This facility treats 50,000 litres of wastewater every single day — transforming it into water that meets potable standards.

Yes… from wastewater to drinking-quality water.

In a country where water security and failing infrastructure are becoming a growing concern, solutions like this are no longer optional — they’re essential.

This isn’t the future. It’s already happening.

Did you know wastewater could be treated to this level? 👇💧
