Floodwater Harvesting for Non-Potable Use
The idea is to collect floodwater for later use.
EXPLAIN YOUR IDEA
Every time it rains in Manila, there is a big chance that its streets will be flooded. Most of the residents living there have adapted to this burden. And lately, rain showers and thunderstorms have become unpredictable. What if, we can turn this inconvenience into something more useful?
The idea is to collect floodwater in cisterns for later use. Filters will be installed at the inlet of the storage to screen out debris and suspended solids.
Flood water will be for non-potable use like gardening,road cleaning, carwashing, or a described in the diagram, for flushing public urinals.
Using floodwater will reduce the need to consume water from the tap, thus, reducing billed consumption. At large scale, this will help mitigate the effects of El Nino since it will allow alternative source of water for non-potable use.
Anyone who lives in low-lying, flood prone areas.Due to collecting of flood water, flooding will be less severe. Also, the collected water will become an alternative source for the community.
Initially, we are looking at streets of Manila which are easily flooded.
HOW DOES YOUR IDEA TAKE INTO ACCOUNT THE CONTEXT OF URBAN SLUMS AND CLIMATE CHANGE?
There is a need for collaboration between community leaders and the authorities as this will cross requirements for installation permits.
