About SewTreat

Smarter Water. Safer Future.

At SewTreat, we don’t just treat water, we transform how businesses across Africa think about sanitation, effluent, and water management.

Founded in 2016, SewTreat (Pty) Ltd has rapidly become a trusted name in the world of onsite water and wastewater treatment. With a footprint in over 15 African countries and more than 250 successful projects under our belt, we’re proud to deliver local solutions backed by international expertise.

Whether your site is remote or urban, industrial or commercial, we design and build modular, scalable, and environmentally friendly systems that put control and savings back into your hands.

Why We Exist

Municipal water tariffs keep rising. Water security is under pressure. And most businesses simply can’t afford to operate with unpredictable water supply.

That’s where we come in.

Our mission is clear: to be the leading onsite water and wastewater treatment provider in Africa, helping businesses cut costs, ensure water availability, and comply with ever-stricter environmental regulations.

Our Promise to You

If your business uses over 30KL of water per month and we can’t deliver water security or help reduce your water bill, we’ll pay you R50,000 in cash. That’s how confident we are in our solutions.

What Sets Us Apart

• Everything in-house: From concept to commissioning, every SewTreat solution is built and managed by our expert team. No outsourcing. No guesswork.
• Tailored to your needs: Our modular systems are designed around your site’s specific water challenges, no matter the scale.
• Savings that scale: Our clients consistently report reduced operating costs, increased water independence, and easier compliance.
• Future-ready: Our technology promotes water reuse, low energy consumption, and minimal maintenance, future-proofing your operations.
• Unmatched support: We don’t just install. We maintain, monitor, and optimize so your system keeps working as hard as you do.

Who We Help

We work with industries where water matters most. Mining, hospitality, retail developments, manufacturing, malls, breweries, and mixed-use properties. If your operation depends on clean water and reliable wastewater treatment, we’re your partner.

Our Vision

Everything we do is built on four pillars:

• Water security
• Cost savings
• Environmental compliance
• Peace of mind
