Reuse: the last but not the least element of the 3R approach

June 10th, 2016By: Rain editor

The biggest challenge of the 3R approach of recharging, retaining and reusing water, is to make water resolve as much as possible. This is because scarcity isn’t only resolved by managing demand through reduction in use, but also by keeping water in active circulation.

 

3 processes that optimize reuse, the 3rd element in buffer management:

 

– Managing evaporation. Water that evaporates can no longer circulate within the system and makes less water available. One source of evaporation is from the soil, which is why it’s so important to keep good soil moisture and avoid any losses.
– Optimizing water quality. Different functions put different demands on the quality. Drinking water must be of higher quality than irrigation supply, for example.
– Ensuring that water doesn’t move to an area from which it’s difficult to retrieve and reuse.

Why all 3R solutions, including reuse, need a tailor-made approach

 

Because buffers differ in size, storage capacity and vulnerability, there is no standard buffer strategy. Different socio-economical and environmental conditions simply set different starting points. That’s why 3R solutions, including re-use, ask for a tailor-made approach. For more information about 3R, contact RAIN.
