Water is the lifeblood of the planet and we have a responsibility to care for it and play our part in conserving it. That’s why we need to shift our reliance from expensive centralized water supply lines to cost-effective decentralized water conservation options that include both rainwater harvesting and greywater harvesting.
The beauty of rainwater harvesting is that it is a water source available to all of us, AND completely free from the sky. When we harvest rain at homes or at our offices, we not only cut out the need for expensive infrastructures, we collect water at exactly the point where we will be consuming it and we embark on an altogether more robust, resilient and planet-friendly approach to water consumption.
Collecting rainwater from our own roofs may also turn out to be the only way of ensuring an adequate water supply for growing populations, increased pressure on antiquated water supply systems and climate change.
The average family of 4 uses around 600Lt of water per day (219 000Lt pa) and almost 90% of that water simply leaves the home as wastewater. Added to this, approximately 60% of that household water which leaves the home as wastewater can be reused as grey water and it is perfect to water gardens, wash cars and driveways and flush toilets.
Greywater is generated in homes every day. The basic sources are showers, baths, hand basins and washing machines. This greywater can be harvested using a Pennell’s tanks greywater harvesting system. The greywater can be reused for non-potable water purposes. Re-using greywater results in money savings in the long term, reduces the need to use expensive potable municipal water for non-potable uses is good news in the face of potentially increasing water prices and it also reduces our carbon footprint.
