Rainwater harvesting (RWH) for rural schools in Cuba

We are looking for suppliers of rainwater harvesting system in order to buy and install these in rural schools in Cuba. 

This Rainwater harvesting (RWH) is a simple low-cost technique that requires minimum specific expertise or knowledge and offers many benefits. For drinking water purposes in rural areas, the most common technique is small-scale rooftop rainwater harvesting: rainwater is collected on the roof and transported with gutters to a storage reservoir, where it provides water at the point of consumption. Collected rainwater can supplement other water sources when they become scarce or are of low quality like brackish groundwater or polluted surface water in the rainy season.

Each rainwater harvesting system consists of at least the following components (INFONET-BIOVISION 2010):

• Rainfall
• A catchment area or roof surface to collect rainwater.
• Delivery systems (gutters) to transport the water from the roof or collection surface to the storage reservoir.
• Storage reservoirs or tanks to store the water until it is used.
• An extraction device (depending on the location of the tank - may be a tap, rope and bucket, or a pump (HATUM & WORM 2006); or a infiltration device in the case the collected water is used for well or groundwater recharge (see also surface or subsurface artificial groundwater recharge).
• A system for diverting this ‘first flush’ water so that it does not enter the tank

We would appreciate if you are interested to provide this system to contact us for taking in to consideration in a future bidding.
