Rain Water Harvesting
Rain Water Harvesting
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 water is generally stored in a rainwater tank or directed to recharge groundwater
The practice of collecting rainwater from rainfall events can be classified into two broad categories: land-based and roof-based
At HYDRO CONCEPTS (U) LTD, we help you design and implement rainwater harvesting systems using recommended technologies such as first flush diverters, filters and water treatment systems. Do you want to harvest rainwater for irrigating your compound or lawn? Are you doing it for later domestic or animal use? Is it for use on fountains? Come to us and we will have it designed and implemented tailored to your need
First flush diverter systems
Whenever it starts to rain, dirt and debris from catchment surfaces and collection devices will be washed into the conveyance systems (e.g. down-pipes). Relatively clean water will only be available sometime later in the storm. This first batch of each rainfall is known as “first flush/foul flush”, and should be diverted from the storage tank
Several manual and automated means of selectively collecting clean water for the storage tanks exist. One such method is the use of automated constant volume first flush diverters
Hydro Concepts (U) Ltd has earned a mark of distinction as a national leader in smart rainwater harvesting technologies, and is thus your trusted partner in undertaking the installation of pre filtration systems like first flush diverters
Rooftop rainwater filters
We install and retrofit rooftop rainwater filters to new and existing rainwater harvesting systems. The rooftop rainwater filter is a simple, low tech, low maintenance technology that filters any physical impurities in your harvested rainwater, prior to storage
Water storage and reservoir tanks
We undertake the construction of bulk water storage and reservoir tanks, both above and underground. Our reservoir tanks have capacities up to 15,000 cubic metres. Our tanks come in a range of sizes and material i.e. masonry, ferro cement, plastic, glass lined steel tanks, and pressed steel water tanks
Our masonry tanks are made from environmentally friendly curved interlocking soil stabilized blocks (ISSBs). ISSBs are approved by UNBS as an excellent material for constructing strong and long lasting water tanks. Our production methods and technologies are environmentally friendly and sustainable since the bricks require only curing, compared to traditional fired bricks that promote deforestation and clay extraction from wetlands. Thus our low carbon building technique reduces deforestation, environmental degradation, unmonitored clay extraction from wetlands, and air pollution via smoke production
Our glass lined steel tanks can be used in water treatment, effluent treatment and sewage treatment plants as equalization tanks, aeration tanks, sludge holding tanks, etc.
Artificial aquifer recharge systems
Under our rainwater harvesting program, we enable you to harness storm water. In collaboration with our international partners, we design and implement surface water filtration systems for high volumes of water flowing from paved surfaces i.e. compounds and roads, and channel this into an injection well. Our systems are excellent in diverting, filtering, and retaining storm water in an injection well, there by augmenting groundwater level. We also use this technology to solve problems of flooding in all settings
Valley dams
We improve agricultural water productivity through up scaling of integrated watershed management via watershed level harvesting of runoff, and erection of micro check dams. These water harvesting and storage facilities ensure reliable water source for livestock and crop irrigation
Our large scale rainwater harvesting, storage and detention facilities such as dams, bunds, and reservoirs help divert flood waters for irrigation, groundwater recharge and flood control
