Groundwater recharge

Rainwater may also be used for groundwater recharge, where the runoff on the ground is collected and allowed to be absorbed, adding to the groundwater. In the US, rooftop rainwater is collected and stored in sump.

Advantages in urban areas

Rainwater harvesting can ensure an independent water supply during water restrictions, though somewhat dependent on end-use and maintenance..................==> [ Click Here to Read More ]

ce system, and storage facilities. The collection area in most cases is the roof of a house or a building. The effective roof area and the material used in constructing the roof influence the efficiency of collection and the water quality.
A conveyance system usually consists of gutters or pipes that deliver rainwater falling on the rooftop to cisterns or other storage vessels. Both drainpipes and roof surfaces should be constructed of chemically inert materials such as wood, plastic, aluminum, or fiberglass, in order to avoid adverse effects on water quality.

Introduction
Three main sources of water can be considered as substitutes for contaminated water: groundwater, rainwater, and surface water. Much has been written about these sources, so this chapter offers only a brief review, with key references.• Groundwater is largely free from harmful bacteria and fecal contamination, though a poorly designed or constructed well can become contaminated from surface water. To prevent this,wells should be grouted around the borehole, and finished at the surface with a concrete platform, with good drainage away from the well.

INTRODUCTION
Rainwater harvesting is the accumulating and storing, of rainwater for reuse, before it reaches the aquifer. It has been used to provide drinking water, water for livestock, water for irrigation, as well as other typical uses given to water. Rainwater collected from the roofs of houses, tents and local institutions, can make an important contribution to the availability of drinking water. Water collected from the ground, sometimes from areas which are especially prepared for this purpose, is called Stormwater harvesting. In some cases, rainwater may be the only av..................==> [ Click Here to Read More ]

ABSTRACT
Water is most abundant component on earth surface, constituting about 70% of the planet surface. Although some 70% of the Earth's surface is covered by water much of this is saline. However freshwater is available in almost all populated areas of the earth although it may be expensive to access the water and the supply may not always be sustainable. Only 4% of the available water is suitable for drinking purpose.
Throughout most of the world, the most common contamination of raw water sources is from human sewage and in particular h..................==> [ Click Here to Read More ]

e, rainwater may even act as the major potable water source for their population.
The most important issue in collecting rainwater is keeping it free of dirt such as leaves, bird droppings and dead animals, and avoiding contamination with pollutants like heavy metals and dust.
Rainwater can be also treated for use as a potable water source. The use of slow sand filtration has proved to be a simple and effective treatment technology for the elimination of most of the organic and inorganic pollutants that may be present in rainwater, as well as producing a virtually pathogen-free water for d..................==> [ Click Here to Read More ]

WHAT IS RWH?

RWH refers to collection and storage of rainwater and also other activity such as

harvesting surface water extracting ground water , prevention of loss through

evaporation and seepage


PURPOSES OF RWH

Stored for ready use in containers ground or below ground
Charged into the ground for withdrawal later
