The issue of high scarcity of water is a global issue now and those countries whose primary revenue sector depends upon the proper distribution of uninterrupted water supply get standstill when their natural water sources dry out.

Rainwater harvesting is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a tank, cistern, deep pit (well, shaft, or borehole), aquifer or a reservoir with percolation. Rainwater harvesting differs from stormwater harvesting as the runoff is collected from roofs, rather than creeks, drains, roads or any other land surfaces. Its uses include watering gardens, livestock, irrigation, domestic use with proper treatment, and domestic heating. The harvested water can also be committed to longer-term storage or groundwater recharge.

Rainwater harvesting is one of the simplest and oldest methods of self-supply of water for households, and residential and household scale projects usually financed by the user. However, larger systems for schools, hospitals and other facilities can run up costs only able to be financed by companies, organization and governmental units.

Rainwater harvesting in for almost every country in the world. The only difference lies in the potential for the rainwater harvesting and the specific methods applied in the areas. Every rainwater harvesting system has a basic formation containing catchment surface, water transportation medium, filtration system and then, the storage system. The only difference is how developing countries are moving in the direction of preserving rainwater.
Our company can help, advise and design a rain water catchment or rain water cistern for free ,- if required -, when you order a prefab unit from us.

Given that rainfall is sporadic and that only a small proportion of global precipitation is easily available for human use, rainwater harvesting can be an efficient means of capturing that precious resource. In cities, much of the rain that falls on buildings, roofs, roads, and other hard landscaping does not percolate into the soil and is instead directed into storm sewers for disposal. Impermeable surfaces cause urban flooding in many areas and generate contaminated unusable water that is directed away from potable water resources. During dry months, local groundwater can be depleted, and many localities struggle to consistently provide enough potable water to meet demand. Rainwater harvesting for nonpotable functions, such as gardening and washing clothes, significantly reduces both the demanded amount of the total fresh water and the strain on stormwater infrastructure. That saving in the demand and supply of potable fresh water is significant in large cities. Although many localities encourage and even subsidize rain barrels and other rainwater harvesting systems, some areas, particularly those in the southwestern United States, view rainwater harvesting as a water rights issue and place restrictions on such collections.

Design Recommendations
The simplest rainwater harvesting systems are nonpressurized systems, such as rain barrels, where the pipes run from rain gutters into a tank. Known as “dry systems,” those structures do not hold any water in the pipes after it stops raining and do not create breeding grounds for mosquitoes and other insects. “Wet systems” are necessary when the pipes cannot be configured to run directly into the tanks. In places where the tanks are located some distance away from the collection surfaces or where there are a series of tanks to serve a number of buildings, pipes from the gutter go underground and then up through a riser into the tank. Such systems are often pressurized so that the long runs of pipes do not retain stagnant water.

Our comnpany will design your rainwater harvesting system , - if so required -, for free in the  event that you place a prefabrication order for one or more units with us. 

Reviews from Bali Prefab World

"We purchased two pre-fab gazebos each 10'x10 and a flat deck 10'x10 and a 10'x10 deck with cutout for around our hot tub and pool. We live in Grand Cayman. My parents and brother each bought a slightly larger gazebo. They both live in Barbados. All our gazebos have alang alang roofs. We are all very happy with the product and in each case Prefabworld Bali International delivered what they said they would. We all used our own labour to put together the kits".
