Water Consumption when Schools are Closed

Published by Ken Nunes on 02/11/2018

Sample school

Here’s a fun fact:

There are 8,760 hours in a year - 365 x 24

The Average school years is ±200 days

The Average school day is 07:00 to 16:00 i.e. 9 hours

Looking at this from a different perspective:

  • Schools are CLOSED 15 hours each day of 200 days per year. 

That’s 3,000 hours (15 hours x 200 days)

  • Schools are CLOSED 165 days of the year.

That’s 3,960 hours (24 hours x 165 days)

  • Total Hours of the Year the School is CLOSED: 6,960 Hours

Therefore, of the annual 8,760 hours of the year, the school is NOT OCCUPIED for approximately 6,960 hours.

Which means, 80% of the year, schools are effectively CLOSED.

Since March 2018, Suntricity has monitored 8 schools in Johannesburg to document Municipal Water Meter Readings at 07:00 in the morning and 16:00 in the afternoon. We can therefore define the following:

  • Water Consumption Outside of School Hours: 16:00 to 07:00
  • Water Consumption During of School Hours: 07:00 to 16:00

Incredibly, Water consumption Outside of School hours is 40% and 60% of the Total Water Consumed - and water consumed when the school is CLOSED, can only be referred to as WASTE

In fact, we coined a phrase for it: BASE WASTE!

The graph of one schools (shown above) is what BaseWaste actually looks like...in RED!!!

Why, you ask, do we focus the predominant part of our working life, dedicated to eliminating WASTE?

Because in most cases, this represents a loss in excess of R250,000.00 per year.

This led Suntricity to develop AQUASTOP™, aimed specifically at eliminating WASTE - Water Consumed Outside School Hours.

AquaStop™ has already saved Hundreds of Thousands of Rand in schools in Johannesburg and we would love to make your school an AquaStop™ School.
