Rainwater Harvesting For Irrigat

Rainwater harvesting systems have become increasingly popular as resources around the world become more scarce. Utility companies and municipalities are finding it more difficult than ever to secure resources fit for drinking, bathing and cooking. This has resulted in inconsistent service and higher prices around the country, hitting homeowners right in their wallets. Unfortunately, this trend shows no sign of slowing down, so anything a homeowner can do to secure their own source of clean water can save money and frustration.

For the most part, rainwater harvesting systems are extremely simple and easy to install. This is particularly true if the liquid will not be used for consumption or bathing. In its most basic form, a collection system consists of a method for gathering the resource from the roof of a building (usually through a gutter) and a storage tank or barrel. This storage container is almost always sealed so that insects and other animals cannot get inside. Also, to prevent the growth of algae, the container must be opaque. Any sunlight will foster the growth of microorganisms that can taint the liquid. However, if it is only going to be used for treating the yard, thorough filtration is not normally a concern.

If the liquid will be used for consumption or bathing, though, it needs to be filtered and kept in a secure reservoir. Rainwater harvesting systems that collect drinking liquid are usually installed underground and are a bit more complex than above ground systems. The liquid is collected from the roof and directed to piping that descends underground. This liquid is often tainted with animal droppings or sediment left behind by air pollution. These contaminants are removed by a filter that sits just outside the reservoir. If there is any overflow, a separate pipe carries the excess to a storm drain. Following filtration, the liquid is pumped into the reservoir at gentle speeds to prevent disturbance of any sediment along the bottom of the tank. The reservoir is typically made from durable metals that are water and airtight. This prevents loss of liquid to evaporation and keeps animals out.

When people in the home need it for drinking, cooking, washing dishes, laundry or bathing, a pump in the reservoir delivers the liquid into the house.

These systems can be designed as small or as large as a homeowner needs them. Simple 60 gallon barrels can provide enough liquid to keep the yard healthy, while a huge tank that holds thousands of gallons can deliver all the water a family needs in a month. The larger the system, the more it costs upfront, but this cost is quickly made up for with reduced utility prices. Also, some states offer tax incentives to families that install these systems, reducing the cost further. Maintenance is usually minimal, but regular cleaning is necessary to prevent any microbial growth.

In all, this technology is a simple way to reduce impact on both the environment and the homeowner’s bank account.
