school - water

Water use in schools tends to be very high. This is due to the a large concentrations of pupils using bathroom facilities. This is further exacerbated  the use of water in irrigation, food preparation and washing activities. There is major scope to save water in schools by installing water saving devices, reusing water and augmenting water supplies. EkoSource has the information and technology to assist schools in becoming Greenius's reducing water consumption and assisting in protecting the environment. 


Our water products are sorted into 4 main categories, measure, reduce, reuse and augment. Measurement enables the users to get a better understanding of water use and potential problems you may have with your water consumption. The value generated from implementing specific solutions varies. In general reducing water use and fixing leaks is the most effective method of reducing water consumption and offers the lowest costs and best returns on investment. While reuse and augmentation solutions tend to be more costly and provide lower returns on initial expenditure.  Please choose the category you would like to investigate in more detail.

Kyalami Preparatory School has become the first Greenius school. Kyalami Preparatory School embarked on a pilot project to determine how much water the school could save by installing water-saving technologies. A water meter was installed to obtain a baseline. EkoSource then installed low-flow valves to the taps and water-saving flush mechanisms to the existing toilets.  The baseline measurement showed an average of 6,7 Kilolitres of water used per week (costing approximately R217,14 per week). Following the installation, measurements showed as little as 1,88 Kilolitres being used per week (R60,50 per week). This equates to a seventy-six percent water saving and the return on investment was realised after one and a half months of savings.

Our water knowledge solutions are designed to enable you to gain a better understanding of your overall water use. This information should equip you with the knowledge required to reduce your overall water consumption and potentially introduce your own solutions to augment your water supply and reduce your dependence on water services from your municipality. The water knowledge portal is separated into 5 main sections, understand, calculate, design, ideas and ask an expert. These will provide you with both free information and paid for services and should enable you to find solutions to reduce your overall water footprint. This will enable you to become a greenius and save some money. Please choose the category you would like to investigate in more detail. 

The information provided by EkoSource gave a great perspective on potential methods to save water and allowed my class to come up with some ideas of their own to implement at home to see if they could further save water.

The business management guru Peter Ducker said “if you do not measure it you cannot improve it.” We would go further to say if you do not measure you do not know if you have improved. In order to understand how to improve water use in your home the first thing to do is measure and understand your current water use. Fortunately, for the most part, domestic dwellings are equipped with water meters so the council can bill you on a monthly basis. You can use these to better understand and improve your water use?  If you would like to understand more on how to use your municipal account and existing meter to identify leaks and benchmark you water use please go to the understand section.

Many people are installing their own smart water meters at household level. While expensive there are several advantages here, namely: 

  1. Early leak detection (There meters are smart and are able to tell you if you have a leak or pipe burst). With municipal meters it may take several months to identify a leak depending on reading frequency. 

  2. It enables you to check the accuracy of water bills from the council. 

  3. It helps for a better understanding of different items household water use. 

  4. Assists in bench marking water use against others and identifying areas of easy water savings. 


Leaks and unnecessary water consumption are major contributors to the overall household water use. It has been shown that in an average household without a garden or pool, water use by toilets accounts for 26.8%, while water from the faucets accounts for 15.7%, showering contributes another 16.7% and leaks account for 13.7% of the overall water budget. However in many houses leaks can go undetected and contribute a much higher percentage to the overall water budget.

It has been recognized that the most cost effective way of reducing your overall water consumption is to target these high water use areas and fix household leaks. These measures can reduce your overall water consumption and reduce your water bill dramatically often resulting in cost saving which pay off the initial expenditure in a matter of months.


EkoSource has a range of solutions which reduce household water consumption and knowledge that enables you to identify and reduce household leaks:

  1. Faucet flow reducers and inset retrofits, these reduce volume flowing in taps in high use areas such as bathroom and kitchen washbasins.

  2. Shower flow volume flow reducers, which reduce however flow volumes but still maintain a good shower pressure with enough volume.

  3. Low flush or two flush toilet systems which are able to reduce toilet flushing by up to 60%.

  4. Finally, household pressure stabilizing valves which are able to maintain a consistent household water pressure and can substantially reduce leaks.

These are the main products to reduce water use and leaks in a household.


There are several options to augment a home's water supply. Rooftops represent a good way of capturing rainfall and water can be used to in various activities such as irrigation and pool filling.Boreholes can also be a good way of supplementing water supply and reducing dependency on disrupted water supply in some areas. EkoSource has a number of options to augment water supply these vary from different water tank options to the drilling of boreholes. 


Water reuse is another area where water savings can be recognized. EkoSource has information relating to the concepts of water fit for purpose and designs for DIY greywater recycling systems. EkoSource is able to provide a number of greywater recycling systems which can be used to provide irrigation water and water to flush your toilets substantially reducing you water bill. The greywater systems do not offer the same return on investment as implementing water saving technology with payback periods being in the region of 1 to 5 years depending on which options are implemented.
