Roof Water Harvesting Structure

Typical roof top harvesting structure under method a the down pipe is moved away from the inlet of the storage tank initially during the rains until clean water flows.

Roof water harvesting structure.

The water is generally stored in a rainwater tank or directed to recharge groundwater. Rainwater harvesting is in two ways. These are cleaned off after each heavy rain. Micro catchment water harvesting is a method of collecting surface runoff from a small catchment area and storing it in the root zone of an adjacent infiltration basin.

Rainwater harvesting is collecting the run off from a structure or other impervious surface in order to store it for later use. Rainwater harvesting simply refers to the collection and storage of run off rainwater for subsequent use. This m ethod provides the best pre tank filtration by way of the w isy vortex filter which is regarded internationally as the best pre filtration m ethod. Rainwater from the rooftop should be carried through down to take water pipes or drains to the storage harvesting system.

Water pipes should be uv resistant isi hdpe pvc pipes of the required capacity. Usually it includes the collecting rainwater from the roof of a house via gutters which will then channel the run off water into some kind of storage container. Rainwater harvesting is a technology used to collect convey and store rain for later use from relatively clean surfaces such as a roof land surface or rock catchment. The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel.

After m ore than 20 years in the rainwater industry rainwater managem ent solutions has identified the w isy 4 step system as the ideal m ethod for rainwater harvesting. Under method b storage provision for initial rain is kept in a pipe. Water collected from roof tops courtyards and similar compacted or treated surfaces is used for domestic purpose or garden crops. Harvested rain water can be stored in subsurface ground water reservoir by adopting artificial recharge techniques to meet the household needs through storage in tanks.

One of the main reasons is their uneven surface it makes it harder for soot and other pollutants and dirt to gather on top of it. The main objective of rooftop rain water harvesting is to make water available for future use. It is easy process to collect rainwater and diverted into ponds vessels or underground tanks to store for longer periods and to recharge by construction of rwh structures in a suitable sites. Catch the rainwater from localized catchment surfaces such as roof of a house plain and sloping ground surfaces etc.

Asphalt shingles are the most common material used on roofs and luckily they are also a very good option when it comes to rainwater harvesting. Water from sloping roofs could be caught through gutters and down take the pipe.
