Stand Alone Rainwater Harvesting System
Cloud Storage
by RainSaucers Inc. on June 22nd, 2011

Detractors of rainwater harvesting point to the seasonality of rain as the main reason RWH can only be a temporary or partial solution to the world water crisis. Others who promote RWH use that seasonality to sell massive, expensive tanks. But what if we challenge some of these assumptions about rain? This includes not just the notion that rain is seasonal but that rain must come in large bursts followed by long droughts.

Cloud Storage, is a term we have recently started using as a play on the more popular data related term. Cloud Storage in the RWH context means that by using the natural frequency of rain combined with a constant usage model, one can potentially make RWH a near year round solution without the added cost of large storage.

Take Orlando, FL for example where it rains an average of 48 inches per year. In 2010, there was rain every month except for October. When the rain was heaviest (March, August and September) it did not come all at once. Downpours were almost always followed by rain again a week or two later. This data suggests that Floridians could make use of rainwater almost year round at minimal cost by using a small barrel- provided they constantly use the water.

We have been using the Cloud Storage term more with our developing world efforts because many poor countries have Florida like weather, raining at least 40 inches per year (with varying frequency patterns). Dry farmers in the developing world already put their trust in mother nature by planting rain dependent crops (corn,wheat,etc.): they understand Cloud Storage. Cloud Storage similarly has the potential to provide poor families with drinking water at very low cost: all they need is a RainSaucer with whatever storage medium they can afford.
