The analysis was done for four categories of rainwater harvesting systems differentiated by the size of catchments from which water is collected and the intensity of concentration and/or storage of the collected rainwater. Along with V- Shaped, Trapezoida l, and Square gutters , a “wrap” design was
Water is vital to all forms of life on the Earth, from plants through to animals and humankind. water harvesting is a substitute and is most important. (2013, April 9). The presence of three major groups of organic compounds, polycyclic aromatic hydrocarbons (PAHs), organochloride pesticides (OCPs) and volatile organic compounds (VOCs), was screened by common analytical techniques. The information was mainly based on recollection as few farmers kept detailed records. Spacers are provided at regular interval.Plumb and level of the formwork are checked for proper alignment and perfect shape. The environmental issue such as flooding, global warming and pollution are getting serious day by day due to a rapid development processes in Malaysia. Water harvesting is a collection of rain and runoff water by using different types of storage structures such as weirs or small dams, primarily for humans, irrigation and livestock consumption. The goal is simple: provide a solution for one person at the CAM. These type of curbs are preferred at openings for pedestrians with shopping carts or strollers, and those who are on bicycles or roller-skates to cross safely on or off the sidewalk.Mowers curbs are used only on the lawn or flowerbed areas. Design of the systems was based on the mass curve analysis for storage and rational formula for the gutters. This paper aims at developing a methodology for establishing the probabilistic relationship between storage capacities and deficit rates of RHS. The total conveyance of a gutter system can available in most of the developing world, including KenFor these reasons, we used galvanized sheet metal to construct the gutters described here. answer, since there is little rainwater to be harvested. Formwork. broader issues associated with technological innovation. Due to the lack of fluoride in rainwater samples, the consumers must become aware of the fact that the supplementation of this element is needed.International Journal of Research in Engineering and Technology the world remind how quickly other countries can run short of water. In arid and semi-arid areas where rainfall pattern is irregular, much of these are lost as surface runoff, and as a result, there is a scarcity of water which results to risk for human beings. The gravel base for both curb and gutter is laid at once and the width of the gravel base will be the combined width of curb and gutter. Common anions and major cations as well as the metals Fe, Mn, Cd, Pb, Cu, Cr, Ni and Zn were tested. As a result, a set of curves describing the continuous relationships between storage capacities and deficit rates under different exceedance probabilities were generated as references to RHS storage design. Hydrological analysis is unavoidable in any water harvesting structural designing. The system can also monitor the quality of water using methods such as turbidity detection, dissolved oxygen/PH/humidity/temperature measurements, besides others. Commonly, concrete gutter is constructed beside pavements. Another finding that goes against the widely held belief is that rainwater harvesting results in more benefits during the above-average seasons compared to below-average seasons. The survey in six districts of the semi-arid Zimbabwe suggests that three parameters (water source, primary use and storage capacity) can help differentiate storage-type-RWH systems from "conventional dams".
Chemical and microbiological parameters showed seasonal fluctuations.

It has been shown that the rainwater harvesting system can support the water demand of the selected house throughout a year even during the dry season. sidewalks, stores, parking spaces, etc.). During the light, moderate, heavysubjected to 1.89L, 5.66L, 13.21L, and 16.99 L amount of rain caught by the gutters.
