From data captured through Real-Time Monitoring in schools in Johannesburg, Suntricity has found that there is (what we term) a "BASE WASTE" of around 10 KL of Water each day...at some schools, this could be much more. 10 KL (the volume detailed on Municipal Invoices) is of course a colossal 10 000 Litres! Yes, 10 000Litres of Water Wasted each day.
At one particular (and very common) school, our Real-Time Monitoring data indicated a constant consumption of approximately 300 Litres every 15-minutes Outside of School Hours.
A survey was carried out with the school's Caretaker, where we found that of the 36-toilets in the school, there were 6 with running leaks. We estimated that each leak (basically the toilet running slightly and very silently), would be responsible for 3 Litres per minute, which of course is 180 Litres each hour and 4 320 Litres each day.
6 Toilets x 4 320 Litres = 25 920 Litres of WATER WASTED each day.
Without Real-Time Monitoring, the magnitude of these kinds of leaks go undetected. However, the 2016 Average Cost of Water (including Sewage) in Johannesburg is R44.50 per KL.
25.92 KL per day is ±R1 100.00 per day of WASTED WATER.
We cannot over emphasise the importance of daily maintenance of the toilet facilities at schools. With over 1 000 learners at school, the already ageing infrastructure is under constant strain and you will be surprised how easy and cost effective it is to repair the kind of cistern leaks which cause the problems described above.
One caretakers at a Primary School in Johannesburg, has someone whose first responsibility of the day is to check and verify if any of the toilets at the school has a leak or if there are any taps dripping. LEAKS AND DRIPPING TAPS ARE IMMEDIATELY REPAIRED.
A 3 Litre per minute problem is barely visible, but cannot be ignored. The multiplication scale in schools will have a major effect on your Water Costs each month.
