Solution Overview & Benefits

The Rain Collection And Purification system (RainCAP) is a foil sheet tank that is made of a sturdy and durable plastic sheet. The foil tank is placed in the ground and used to collect/capture up to 50 cubic meters of rainwater. From there the water is pumped up, purified when needed and distributed as drinking water to the consumers. Collected water can be stored for a period of up to 8 months dependant on level of maintenance.

The RainCap system is easy to transport, install and maintain. It can be installed in combination with the UV WaterBox. The tank can be cleaned regularly and removed when needed. The RainCAP system has a lifetime of ten years or more.

Target group and delivery: The RainCAP is designed for usage in tropical countries with modest to high rainfall. Sizes are family level (with a 15 m3 tank) and village level (a 50 m3 tank). The tanks follow a modular design and can be linked dependent on the needs of the client. The 15 m3 tank serves an extended family of 30 people for 8 months consuming 2 liters per person per day. The 50 m3 tank serves a village of 200 people drinking 2 liters per person per day for 4 month.

Rainwater Catchment area: Capturing of rainwater is best done using existing roof systems. Schools, medical centers and governmental buildings can be often deployed for that purpose. By installing rainwater gutters along the roofs the water is collected. The RainCAP system is attached at that point to take care of the filtering, storage and purification of the water. The total of the collected rainfall is dependent on the condition of the roofs, the gutters and the level op maintenance in combination with the local rainfall pattern.

Limitations: The RainCAP system is best applied in tropical regions displaying moderate to high rainfall. The systems can be installed in relative soft ground (compacted sand, silts, etc.). It is advised to avoid sharp rocks surfaces in order to prevent puncturing of the foil material.
