Stand Alone Rainwater Harvesting System
Requiring Rainwater Collection
by RainSaucers Inc. on October 12th, 2011

A RainSaucers fan recently alerted us to the situation in Tuvalu where a drought has drawn down the island nation's water supply to crisis levels. As reported in Reuters, rescue efforts are underway from nearby OZ and NZ which are providing emergency desalination equipment. Tuvalu is one of an increasing number of countries that are entirely dependent on rainwater. One could argue this means RWH always needs a backup for when weather conditions change dramatically. But we think it can also mean that RWH systems must be sized, not based on averages, but on the worst case situation. In other words, when rain falls, however little it may seem, it can go a long way if you collect it over the right collection area.

Furthermore, Tuvalu is not alone in its dependence on rainwater. Several island states face the same situation from the Bahamas to Hawaii. Meanwhile in Australia and Texas, droughts have created the same situation by depleting wells until dry. But even during "drought" conditions there is rain: one just needs to be ready to capture it whenever and wherever it falls.
