Rain Water Management by Lance Casey

Water resource management is the activity of planning, developing, distributing and managing the optimum use of water resources. It is a sub-set of water cycle management. The field of water resources management will have to continue to adapt to the current and future issues facing the allocation of water. While rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit (well, shaft, or borehole), aquifer, a reservoir with percolation, or collected from dew or fog with nets or other tools.

Why Save Rainwater?

Rainwater can be used for potable water (drinking, cooking, bathing) or non-portable uses such as landscape irrigation, livestock watering and washing. Collecting and using rainwater has numerous benefits, ranging from improved water quality to reduced stress on underground aquifers. But after it falls from the sky, rainwater percolates through the earth and rocks, where it picks up minerals and salts. Rainwater typically has very low hardness levels, which reduces the use of soaps and detergents, and eliminates the need for a water softener. Rainwater harvesting reduces the impact on aquifers, lessening the demand on ecologically sensitive or threatened aquifers. Collecting some of the rainwater falling on impervious surfaces also minimizes erosion and flooding: On some lots, as much as 50 percent of the land area is covered by roof surface. Stored rainwater also is a good standby in times of emergencies such as power outages or during periods of extreme drought when wells dry up. In some areas where water supplies may not be available or dependable (or may be prohibitively expensive), collected rainwater is sometimes the least expensive option and can easily be less expensive than bottled water.

Convert your downspout for rainwater harvesting by piping your rainwater into a barrel directly via the downspout of your gutter system and one the barrel is full; you can have the excess run over and out. There are countless methods of design: corrugated metal culvert adds a farm-inspired twist for permanently storing water that comes down from your gutters. Or have your rainwater barrels stored out of sight and out of mind, by having them underground. Prefer something a bit more “high tech” when it comes to rainwater collection? Included a overflow system with a hose hookup so that you can stretch your water as far as a garden hose can; whether it’s filling up the horse trough or watering your garden! Be inventive! And have Fun.
