School Rainwater Harvesting & Water Use Study, Co. Mayo

The aim of this study was to monitor water use and assess the efficiency of a rainwater harvesting facility installed in a primary school.

School Rainwater Harvesting & Water Use Study, Co. Mayo

This study was designed to monitor the efficiency of the RWH system installed in Carrowholly NS, Westport, Co. Mayo. The project team was led by Liam McCarton and included Dr Sean O’Hogain and Anna Reid. The duration of the study was 21 months.

Fit for purpose

Currently all mains water supplied to schools is treated to drinking water standard, regardless of the end use. 

The concept of “fit for purpose” water means that the quality of the water being used is  of sufficient quality for the task in hand.

Treating water to drinking water standards to flush it down the toilet is not sustainable.

Project Information

This study was designed to monitor the efficiency of a school  rwh system.  The study also monitored per capita consumption rates for toilet use in schools.

Rain Harvesting Co.Mayo

 

Two separate  rainwater harvesting (rwh) systems were installed within the attic roof space of the school. Rainwater from either side of the roof catchment drains to a hidden rainwater guttering system. 

Rainwater is collected in a 450 L water tank. Any excess overflows to the drainage system.   

The rwh system supplied water to a number of toilets in the school.

The installed rwh system was  required minimal ongoing maintenance with no pumping costs. 

The school rwh system reduced mains water use to toilets by  52%.
