Rain Water Harvesting


Rain Water Harvesting is the method of accumulating and storing rainwater instead of allowing it to run off the land or be absorbed into the land and be wasted. Rainwater is free and can be utilized in remote or isolated areas, rural and urban communities who have a limited resource of water or want to exercise an alternative water solution. Rainwater harvesting is for all types of businesses, agricultural, individuals and families to provide numerous Eco friendly benefits, save money and help protect the environment.

Rainwater harvesting has been used for thousands of years as a resource to collect rainwater around the world in order to provide people with drinking water, irrigation and other non-potable uses.


Potable Collecting rainwater is cost effective for potable (drinkable) purposes for your home or business.

Non potable The majority of the water we need is used for non-drinking purposes. For inside the home, non-potable rainwater can be used from washing clothes and dishes to bathing and flushing toilets which all require a large volume of water. Rainwater is soft and can lessen the need for detergents when washing clothes and dishes. Rainwater can also be used for all your cleaning or washing of vehicles, sidewalks, the siding on your home, windows or use to bath your animals and pets.

For outdoor applications, rainwater is excellent to provide water to livestock, wildlife and pets. Rainwater harvesting also improves the quality of plants and gardens, as harvested water can flush the salt buildup from plants and soil. Harvested rainwater is generally free from various pollutants and man-made contaminants and is free from chlorination.

In summary, using rainwater is clean and healthy for plants, trees and gardens that can save costs on property maintenance, irrigation and landscaping.


Over time, natural springs have reduced their water flow or have completely dried up. Rivers and lakes have become polluted due to population growth. Bigger population and urban development also increases storm water runoff and decreases water infiltration into the ground where it falls. All of these concerns have a direct impact on the water quantity and water quality we encounter today.

Rain water harvesting reduces flooding and erosion on your property that occur around the downspouts and in gardens. It can also control storm water run-off. Rainwater doesn’t produce scale and corrosion as hard water does. The collection of rainwater may reduce flooding in certain areas, such as around the exterior perimeter of the premises or at the lower grades of the property where the water gravitates to that has no proper drainage.

Rainwater harvesting helps individuals save on their water bills and can reduce costs to the overall community. The expense to supply municipal water to the community can be substantially reduced if numerous residents use rainwater. Providing an alternative source of water also minimizes the concern if municipal water contamination occur or any other emergency situation. Rainwater in many countries is used as a primary source of water or an alternative source when needed.

It makes sense to use rainwater whenever possible. Harvested rainwater can be stored and then used during times of drought and when the ground water supplies have been depleted.


Rain water collection systems range from 10,000-gallon cisterns to 40-gallon rain barrels. Even though maintenance is required on rainwater collection systems, these can be constructed to efficiently maintain.

Digging deeper wells is not only expensive but can cause environmental damage in soil collapse when the water disappears. Also, if your well water is substandard for drinking or may be drying up, Please Contact Coastal Water Store to discuss the option of using a rainwater collection system that is designed for your needs and installed by us which is often more cost effective than drilling a well.
