Water saving tip #13

Become a mindful toilet flusher



A toilet of modern design typically uses about 8 L per flush. For a 4 person household, each of whom flushes 4 times a day, this amounts to 47 000 L per year, which is 35 % of the average household’s domestic water bill, used exclusively for flushing. All of this water is furthermore potable municipal water which should undeniably be put to better use than ushering away our daily bowel and bladder movements.

In our very first water saving tip, we showed how a lot of water is saved by applying a simple DIY design improvement to your toilet: place water bottles or bricks in your toilet cistern.

But despite such efforts, the toilet remains a chief offender in domestic water consumption. Becoming a mindful flusher in both habit and design is therefore key to optimally conserving this vital resource in your daily routine. Today’s tip suggests 3 ways of becoming a mindful toilet flusher.

1. Only flush when necessary

The classic rule of “if it’s yellow, let it mellow, if it’s brown, flush it down” still applies. For the more delicate souls we recommend the following amendment: “If it’s odourless and a light shade of yellow, let it mellow…” Whatever your preference, we at WETT encourage, at the very least, a moment of consideration before pulling the flush lever. Only flush when necessary.

2. Do not flush foreign objects down the toilet

A surprisingly prevalent urban blind spot is the view that the toilet doubles back as a water enabled trash can. Objects like cigarette butts, floss, grease, oil, food & fats, band aids, medication, paper towels, hair and even insects regularly find their way down the spiraling portal of the toilet bowl.

Apart from the considerable challenges faced in removing foreign objects and substances from sewage, clogging occurs, leading to burst pipes and mayor water wastage. The fact is that the toilet is a specialist disposal designed only for human waste and toilet paper. Even tissues and most other types of paper are too thick and leads to clogging. Do not flush foreign objects down the toilet.

3. Harvest rain water for domestic use

Rain water falls freely from the sky on a regular basis. A great way to prevent wasting potable municipal water on flushing is to re-use rain water. Depending on the number of tanks, down-pipe positions and whether water is simply stored or integrated for domestic consumption, a full rain water harvesting system can cost anywhere from about R 10 000 upwards.

This may seem like a large cost, but is typically earned back within a couple of years, saving thousands over a lifetime. Check out our rain and grey water harvesting services to start saving today!
