Twenty years ago...

Today we were on our way to assess another sewage treatment plant on the KZN South Coast when Mat casually mentioned, "I installed a plant not far from here about 20 years ago."

Naturally, we had to go and find it.

After a bit of searching, we arrived at what is now Sugar Beach Resort (previously Phefamula). The maintenance team were kind enough to let us have a look around.

To be honest, we didn't know what to expect. But what we found was a pleasant surprise.

The plant was still in very good condition. The maintenance staff told us that, apart from replacing pumps over the years (which is pretty normal), they couldn't remember the system ever needing any major work.

Back at the office, Mat remembered he had an old photo from when the plant was first installed. After digging through the archives, we found it.

The date on the photo? August 2006. Almost exactly 20 years ago.

It was pretty special seeing that old photo alongside the plant that's still quietly doing its job all these years later.

In our line of work, new plants always look impressive on day one. The real test is whether they're still doing what they were designed to do twenty years later.

Sometimes the best solution isn't replacing everything... it's making better use of what's already there.

More than 15 years ago, Clearedge Projects installed the wastewater treatment plant at Rivermead Estate. It served the estate well for many years, but over time the system was modified and eventually started struggling to produce compliant effluent.

After repeated non-compliance notices from the municipality, we were asked to see if the plant could be saved.

Instead of recommending an expensive new treatment plant, we took a different approach.

By converting the existing underground concrete structure into a permanent treatment facility, we were able to create:

✅ A new balancing tank
✅ Two new SAFF bioreactors
✅ Improved aeration and biological treatment
✅ Continued use of the existing clarifier and contact tank

The result? A reliable treatment plant that's back to producing compliant effluent and ready to serve the estate for many years to come.

Every wastewater treatment plant has its own design and operating principles. Sometimes a fresh look from the original designer can unlock a simpler, more cost-effective solution than starting from scratch.

If your estate is dealing with compliance issues, unpleasant odours or increasing maintenance costs, we'd be happy to have a look.

Nature’s Approval 🐸

One of our favourite discoveries during a routine inspection wasn’t on a checklist - it was this little frog happily living inside one of our bioreactors.

Frogs don’t drink water through their mouths like we do. Instead, they absorb water directly through a specialised patch of skin on their bellies. They also breathe through their skin, which is highly permeable.

The downside? They can’t simply “switch it off.”

If the water they’re living in is polluted, they absorb those contaminants directly into their bodies. That’s one of the reasons amphibians are often considered nature’s early warning system for environmental health.

So while one frog doesn’t scientifically prove our treated water is perfect, we’d still take it as a pretty good compliment from nature.
