Rooftop rainwater harvesting systems are a sustainable and efficient way to collect, store, and use rainwater for various purposes such as irrigation, toilet flushing, and laundry. These systems are composed of several components that work together to collect, filter, and distribute the rainwater.

One of the main components of a rooftop rainwater harvesting system is the catchment surface, which is usually the roof of a building. The catchment surface should be sloped and have a large enough area to collect a significant amount of rainwater. It should also be made of materials that are resistant to corrosion and algae growth, such as metal or concrete.

Another important component is the gutter and downspout system, which is responsible for directing the rainwater from the catchment surface to the storage tank. The gutter is a channel that is attached to the edge of the roof, and the downspout is a pipe that carries the water from the gutter to the storage tank. It is important to ensure that the gutter and downspout are properly installed and maintained to prevent clogging and leaks.

The storage tank is the component that holds the collected rainwater until it is needed. There are various types of storage tanks that can be used in a rooftop rainwater harvesting system, including above-ground tanks, below-ground tanks, and cisterns. The size of the storage tank depends on the amount of rainwater that is expected to be collected and the needs of the user.

A filter system is also an important component of a rooftop rainwater harvesting system. The filter removes any debris and contaminants that may be present in the rainwater, such as leaves, twigs, and dust. There are different types of filters that can be used, including mechanical filters, biological filters, and chemical filters. It is important to regularly maintain and clean the filter to ensure that the rainwater is safe to use.

Finally, the distribution system is responsible for delivering the filtered rainwater to where it is needed. The distribution system can be as simple as a hose or as complex as a network of pipes that deliver the water to multiple locations. It is important to properly design and install the distribution system to ensure that the rainwater is delivered efficiently and without any leaks or other issues.

In conclusion, a rooftop rainwater harvesting system is composed of several components that work together to collect, filter, and distribute the rainwater. These components include the catchment surface, the gutter and downspout system, the storage tank, the filter system, and the distribution system. Proper design and maintenance of these components is essential to ensure that the system is effective and efficient in capturing and using rainwater.

Rooftop Rainwater Harvesting & Advantages of Rainwater Harvesting (2022)

At every outlet and inlet point of the channel, fine graded mesh is implanted to prevent entry of finer materials into the sump. For a more thorough review of the different storage options for harvested water, see our Harvested Water Storage page. We have a team of seasoned experts in scoping, engineering, fabricating and delivering best-in-class full-service water harvesting solutions. Source: A water harvesting manual for urban areas Channels all around the edge of a sloping roof to collect and transport rainwater to the storage tank. Wahaso offers both standardized and custom rainwater harvesting systems.

Recharge trenches A recharge trench is a continuous trench excavated in the ground and refilled with porous media like pebbles, boulders or broken bricks. Harvesting of Roof-top rainwater In rooftop harvesting, rainwater is collected from the roof of the house or building. This allows room for a leaf eliminator and connection to a first flush described below. If our standard systems do not fit the project, Wahaso will work with architects and engineers to design a custom system. The way in which gutters are fixed mainly depends on the construction of the house, mostly iron or timber brackets are fixed into the walls. Gutters can be semi - circular or rectangular and mostly made locally from plain galvanized iron sheet. The Wahaso commercial rainwater harvesting systems produce treated water that is safe and suitable for non-potable applications such as toilet flushing, irrigation and cooling tower make-up.

Top 5 Important Components Of Rainwater Harvesting

Overflow pipe must be installed to allow the water to overflow if your storage tank get full. Rooftop rainwater harvesting is one of the economically viable and optimistic ways of rainwater harvesting. On top of the storage tank gravel, sand, and netlon mesh filter are designed and placed and in keeping the rainwater in the storage tank clean this filter is very important because from entering the storage tank it removes silt, dust, leaves, and other organic matter. The annular space between the borehole and the pipe is filled with gravel and developed with a compressor till it gives clear water. That being said, it seems that the general consensus is that piping that carries water from any AWSS shall be purple in color and labeled every 5 ft as to its contents. A roof made of reinforced cement concrete RCC , galvanised iron or corrugated sheets can also be used for water harvesting.

It consists of pebbles, gravel and sand layer which acts like a filtering media. Its biggest disadvantage is that the UV has no residual killing effect — so that algae and other pathogens can still form down stream of the system. By using the appropriate method, we can catch this runoff and use it for recharging aquifers. In such situations, the desilting chamber holds the excess amount of water till it is soaked up by the recharge structure. Other sterilizing agents that can be used include Ozone and Chlorine Dioxide. Both filter types are generally stable, making full use of the natural purification process of harvested surface water and do not require any chemicals.

The rooftop rainwater harvesting system is a pretty simple and low-cost technique that requires minimum specific knowledge and it gives maximum benefit. A system is designed with three concentric circular chambers in which the outer chamber is filled with sand, the middle one with coarse aggregate and the inner-most layer with pebbles. Sizing of the UV system is critical to maintain sufficient exposure rates to keep the water sterile. The inlets lie below potential contaminants that are floating on the surface, and above any sediment that might have accumulated on the bottom of the tank.

In addition to monitoring the system mechanicals, the control system can track the amount of water in each tank and track and display the monthly amount of water harvested. They can be made of plastic, galvanized steel, stainless steel, or cement. The annular space between the borehole and the pipe is filled with gravel and developed with a compressor till it gives clear water. While this reduces the volume of water available, it does make householders eligible for waivers on their rainwater drainage fees. The charges that are levied on each square metre of roof area and sealed surroundings can be substantial, such as in Bonn, so waivers often provide significant savings.

Cost of Rainwater Harvesting The costs associated with rainwater harvesting system are for installation, operation and maintenance. Unfortunately, this is not a good surface from which to harvest rain that is intended for potable use. In order to facilitate speedy recharge, boreholes are drilled at regular intervals in this trench. The rainwater quality may be affected by air pollution, bird droppings, insects, dirt, organic matter, etc. Rainwater coming out of the lid sieve then passes through three layers of sponge and a 150 mm thick layer of coarse sand. It would be pretty hard to refuse if, you get a free water supply for your home and for your garden and this can be only possible through rooftop rainwater collection system. It will taste better and be better for your body, skin, and hair.

He has been published in several publications and writes data book chapters for ASPE. A roof made of reinforced cement concrete RCC , galvanized iron or corrugated sheets can also be used for water harvesting. The lid is turned over and holes are puched in it. The size of the gutter during the highest intensity rain should be according to the river. First-Flushing: The first spell of rain carries a large number of pollutants from the catchment area and air, so first flushing is required.
