Water Saving Systems & Green Plumbing Alternatives

Water is very precious, so we make sure that no drop is wasted.

We can assist with rain water harvesting, water recycling.

Rain water harvesting

Consider water shortages in the near future due to drought.
Let us help you design water reticulation systems to resolve immediate water shortage issues from harvesting of rain water and other sources, to resolve the situation.

Grey water recycling

Grey water is defined as all wastewater generated in households or office buildings without fecal contamination. Sources of greywater include: Showers, baths and clothes washing machines. Grey water is generally safe to handle and easier to treat and reuse provided the use of non-toxic soap and personal care products are not used. It is not advisable to use your kitchen water as this is damaging to plant life because of the fat content.

A bath uses 120 liters and a shower 80 liters. You pay for it, then it all goes down the drain. You can use this grey water to immediately irrigate your garden or for flushing your toilet.
Watt’s plumbing has extensive experience with commercial and residential grey water systems.


Early in 2017 Empire Cafe decided to install a grey water system for toilet flushing. Watts plumbing did the installation. With minimal system maintenance we have not used mains water supply to flush the Empire toilets for many months! I recommend a similar system to any business with public toilets. The cost and water savings are significant!

Tips on Saving Water

    Watt’s Plumbing has been our preferred plumbing contractor for the Wittebome Estate Constantia for many years. The Estate, which comprises of multiple units, has both modern and old ‘Heritage Site’ structures, which can be challenging work … something Watt’s Plumbing handles with aplomb. They are available to attend to all our plumbing crises 24 hours a day, seven days a week. They communicate with the relevant parties ensuring that all involved are informed of what needs to be done, and it is reassuring to know that a fair price is charged for their professional services. I can honestly recommend the owner, Charles Watt and his teams at Watt’s Plumbing for any plumbing work required

    Watts plumbing have been our plumbers for around 7 years. We have always had magnificent service – never having waited for more than a few days for less urgent calls, and the same day service for anything more serious. The quality of their work has always been of highest standards, their service more than efficient (in fact they often go out of their way to ensure you get your parts etc.) and the staff are all a pleasure to deal with and have around I feel more than confident to, (and often do) recommend them to all my friends!

    Over the past ten years I have used Watt’s Plumbing for a whole host of plumbing jobs, ranging from blocked drains, sorting out leaks to plumbing a new house I built. Every time I’ve used them I found them to be obliging, professional, courteous, reliable and efficient, always delivering a high quality of workmanship. Their pricing is also very fair and reasonable. As far as plumbing goes, I have every confidence in their well-trained teams and will continue to recommend them whenever anyone asks me to recommend a plumber.

    Wattapac was used. The water was pumped out from the broken geyser into a heavy-duty ‘bag’ and then once the new geyser had been installed the same water saved was repumped back into the new geyser.

    The pumping out took approximately 5 minutes as did the pumping in of the saved water back into the new geyser. The whole process was super-efficient, there was no water loss and the process took less than an hour. An amazing product! Thank you.
