“Water ,Water Everywhere and Ne’er a Drop to Drink.”
The line from the “Rime of the Ancient Mariner” may have some resonance with our modern situation.
In light of the past water disaster that Gauteng faced, the
reality of fresh water supply hit uncomfortably close to home.
For the longest time, we had perhaps taken that instant gush of H20 from the tap for granted, that as we turned that steel faucet, the life giving flow of crystal clear liquid would always be there.
Well, for many people across Gauteng in the last few weeks, that assumption was literally ‘blown out of the water’ as a power failure at a pumping station and lower reservoir capacity left thousands without water.
There is an advert doing the rounds again that says that “The next World war will be fought over fresh water.”
Perhaps this isn’t too far away from the truth.
The good news is that we can ALL do something about it and, we can do it right now.
Way back in July of 2013, I took a decision to start offering Saving Energy website visitors a way to reduce their electricity consumption by providing a service to supply and install geyser timers and then geyser blankets. Since then , we have installed more than 300 countrywide and growing.
Today, I am going to take this this principle to saving water.
Your shower,a pleasure and a way to save a LOT of water.
Many years ago, the shift from bathing to showering took place. We came to understand that using bathwater was wasteful and that showering was a more efficient use of water for getting clean – and probably more fun too!
I can’t imagine some of those sexy movie scenes being shot in a bath! Although, to be fair, there have been some good ones in baths too!
Let’s look at the shower in a bit more detail.
In an average home, a 5 minute shower using 20 litres of water per minute, will use 100 litres of water in that shower- PER PERSON.
Let’s say that we split the hot/cold water 50/50 just for this exercise.
So, of that 100 litres, 50 litres is hot water and 50 litres cold.
100 litres is 50 X 2 litre bottles of fresh water.
There are 2 people in the house.
That’s 200 litres of water ; 100 litres of hot water and 100 litres of cold water.
Per week= 1400 litres or 1,4 KL (kilo litres).
Per month = 42 000 litres ( 42 Kl).
Per year = 432 000 litres (432 Kl).
There is a feature on Saving Energy that I wrote a few months ago about how I cut my water usage in half using a water and energy saving shoer head . You can read it here.
Let’s apply this to the numbers above.
If I cut my shower usage in half , this is what those numbers will look like.
In an average home using an energy/water saving shower head :
A 5 minute shower using 10 litres of water per minute, will use 50 litres of water in that shower- PER PERSON,PER DAY.
Per week= 700 litres or 0,7 KL (kilo litres)
Per month = 21 000 litres ( 21 Kl)
Per year = 216 000 litres = 216 Kl
That saves 216 000 litres of water.
That’s enough water to fill my swimming pool 3 times over.
According to research and agreed upon global stats,the average human being needs around 50 l of water per day for drinking and personal hygiene.
By me putting in just ONE energy and water saving shower head, I saved enough water for 4320 people to have that 50 litres per day.
Now , consider this.
For every average household that installs ONE energy and water saving shower head, 4320 people will have their water ration every day.
If 365 people that read this article go and install an energy and water saving shower head, 4320 people will have their water for a whole year.
Just think about that, the next time you shower with your old water-guzzling shower head.
If 1000 people installed ONE energy and water saving shower head, they would save 216 Million litres of water per year.
But wait,there’s more.
Here’s the answer.
Lower water costs for you every month for starters and lower electricity costs too.
By reducing your water usage in your shower by half, you use half the amount of electricity to heat that water used in your shower.
According to the latest water tariffs from Ekhurhuleni*, if you are using between 31kl and 45kl per month, this would cost you R16-53 per kl- or R753-00 per month for 45kl water.
Cut that by a third (15kl) and that brings your water cost down to R500-00 per month ,saving R3000-00 per year…JUST ON WATER.
You can probably add another another R200-00 per month on to that for the electricity cost on heating half the water for the shower.
So, let’s say R450-00 per month saving , or R5400-00 per year.
In an average house these days , with 4 people – two adults and two children – I would estimate that the average monthly utility invoice is between R2500 and R3000-00.
That’s a saving of about 15%.
Here’s the good news.
Not only will the cost of a quality energy and water saving shower head be LESS than the monthly saving and the shower itself has just as much pressure as your water guzzling one,plus it’s really easy to install – the most important part of this is that EVERY time you shower and lok=ok up at that energy and water saving shower head you put in after reading this , YOU KNOW that you are actually DOING something that goes a long way to saving the most precious resource on Planet Earth.
