A rooftop rainwater harvesting system consists the following elements: Collection area, .Water harvesting is the deliberate collection and storage of rainwater that runs off on natural or manmade catchment areas.In saline or coastal areas, rainwater provides good quality water and when recharged to ground water, it reduces salinity and helps in maintaining balance between the fresh-saline water interfaces.Water pollution signifies contamination of water bodies, which makes their water unfit for drinking and other purposes.The rooftop rainwater harvesting is less expensive, easy to construct, operate and maintain.

For non-domestic buildings a larger RWH system is required, so it is suggested to consult the British Standard Code of Practice 8515:2009 – Rainwater Harvesting Systems (8) for a more accurate design.The results in (Roebuck,2008b) (5) suggest that rainwater harvesting systems are not cost-effective as the long term difference tended to be a deficit equal to the initial capital invested in the RWH system.Roebuck shows that previous reports showing the cost-benefits of rainwater harvesting systems are unreliable and have not been extensively investigated.There are three main types of rainwater harvesting system: .The main consideration for installing a rainwater harvesting system will be the savings that can be achieved.

Water and dissolved solutes move through the symplast system from cell to cell by diffusion (Ben-Yehoshua & Rodov, 2003).Fresh produce continues to lose water after harvest, but contrary to the growing plant it cannot replace lost water from the soil and so must use up its water content remaining at harvest (Gustavo et al., 2003).Permiability to water usually depends more on amount of waxes than on the thickness of cuticle (Kramer & Boyer, 1995).The apoplas provide an alternative avenue for liquid water movement by hydrostatic pressure through the interfibrillar spaces in the cell wall (Woods, 1990).There are three major routes for moisture loss from harvested commodities to the atmosphere: (a) through outer layer that forms a su...

More water results in a slurry that is less and less sticky until it reaches the saturation point where it becomes cloudy water.This effect can be obtained by adding deflocculants, such as sodium hydroxide and sodium silicate in an amount of 0.1 to 0.4% clay, or by replacing the water entirely with humic acid, tannic acid or horse urine.The humidity of the sand and the water in the slurry must be taken into account to obtain a mortar with the right proportions and the right consistency.Until saturation, adding water to the sand makes it more cohesive.These substances allow less water to be used, give less shrinkage and quicker drying.
