What commitments are you making to saving water?
Water is a vital, life-sustaining resource that is becoming increasingly scarce, posing significant challenges to ecosystems, industries, and human life🌍 Yet we still routinely use precious treated drinking water for purposes for which it is not required🚰
We need to recognize the value of water, especially treated drinking water, and act to protect and conserve it💧🌿
A great place to start is our own daily lives, where sustainable daily water use habits around toilets and kitchen activities can significantly lower water consumption without requiring major changes or investments. At GroundTruth, we are making small but significant changes.
1. We are switching from using potable municipal water supply to using rainwater for flushing toilets, achievable through installation of rainwater harvesting into tanks and some simple plumbing changes🌧️
2. We have installed outdoor “L'Uritonnoir” self-composting zero-water urinals♻️
So what are the impacts and benefits?
First, we’re saving precious treated water, which is critical in a severely water scarce country💧 But the advantages of water conservation go beyond immediate resource preservation. By reducing treated water wastage and harvesting local rainwater, we decrease the need for expensive and energetically demanding development and maintenance of water infrastructure like distribution networks, dams, and treatment plants⚡
Since implementation, we have noticed a big reduction in monthly costs and treated municipal water use. A quick calculation reveals the significance:
Assuming: the cost of treated, municipal water is R0.013 per litre; without urinals, there would be roughly 6 toilet flushes per person per day; and toilets use roughly 9 litres per flush. So:
▪️ Daily use: 26 people x 6 x 9 L per flush = 1,404 litres/day
▪️ Monthly use: 1,404 x 22 = 30,888 litres per month
▪️ Annual use: 30,888 x 12 = 370,656 litres per year
▪️ Monthly cost is 30,888 x 0.013 = R401.54
▪️ Annual cost saving is R401.54 x 12 = R4,818.53
Once scaled up to our other offices, we will take pressure off the grid and reduce our wastage of high quality, treating drinking water for simply flushing toilets by over 700,000 litres per year!🌊 A neat added bonus is the financial savings could increase to >R10,000 per year📈
Simple actions for sustainability can lead to meaningful positive change over time, saving money and water in the process🌱 By preserving water in small ways today, we can ensure its availability tomorrow.
