Quench – Rainwater Harvester

In the case of a natural disaster, urban dependency on mains water supplies can be unreliable. Quench is a water conservation product designed for down-pipes in public spaces, allowing quick and easy filling of virtually any vessel in case of emergency or limited mains water supply.

Quench is a water conservation product designed for public spaces, allowing quick and easy filling of virtually any vessel in case of emergency. It works by collecting rainwater in a reservoir, which is constantly refreshed and replenished as rain falls. The small size of the reservoir means Quench can be retrofitted to existing drainage systems without extra structural support.

Units are mounted unobtrusively on downpipes around urban environments, easily accessible by the public if the mains water supply becomes unusable. Physical debris is filtered out of the water and collected in a separate container. The transparency of the container means that only a quick visual inspection is required to check if it needs emptying, and council staff can remove the organic matter for composting. 

In the case of a natural, or even unnatural disaster, urban dependency on mains water supplies can be risky. A break in the line can quickly render the supply useless. Quench recognises that when a disaster does strikes, there will be a need for instant access to clean water. While emergency public water tanks provide a medium-term solution, they are placed far and few between, with none in the CBD. 

Quench provides a solution to the instant requirements of all nearby residents and people in public spaces. It is a low cost, easy-to-implement drink station for emergency use in urban areas. Easily installed on any sized down-pipe with simple adapters, with an inoffensive yet recognisable aesthetic, this system is appropriate in both urban and suburban environments. In high traffic areas, more units can be installed through down-pipe branching.
