Rooftop Rainwater Harvesting

Allegiance Zincalume Water Storage Tanks are highly demanded for rainwater, firewater, de-mineralized, raw water, drinking water and waste water storage purposes due to their excellent durability and zero maintenance features. These are highly customizable, easy to install, lightweight and versatile. The unique advantage that makes these tanks a smart choice is the bolted panel structure, i.e. the panels are bolted on site and the tank is ready to use right after installation. Also, these tanks can be unbolted and reinstalled whenever required, providing great flexibility. We only use the premium grade of Steel, which is coated with 55% Aluminium, 43.5% Zinc & 1.5% Silicon, to fabricate our tanks. In order to extend the high performance, a liner is installed inside the tank to ensure that the tank wall does not come in contact with water.

Allegiance Rain water Harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilized in different ways or directly used for recharge purposes. ... RWH An effective method in water scarce times, it is also an easily doable practice. Rainwater harvesting systems consists of the following components: Catchment- Used to collect and store the captured Rainwater. Conveyance system – It is used to transport the harvested water from the catchment to the recharge zone. Flush- It is used to flush out the first spell of rain. Filter – Used for filtering the collected Rainwater and remove pollutants. Tanks and the recharge structures: Used to store the filtered water which is ready to use. The process of rainwater harvesting involves the collection and the storage of rainwater with the help of artificially designed systems that run off naturally or man-made catchment areas like- the rooftop, compounds, rock surface, hill slopes, artificially repaired impervious or semi-pervious land surface. Several factors play a vital role in the amount of water harvested. Some of these factors are: The quantum of runoff Features of the catchments Impact on the environment Availability of the New technology The capacity of the storage tanks. Types of the roof, its slope and its materials The frequency, quantity and the quality of the rainfall The speed and ease with which the Rainwater penetrates through the subsoil to recharge the groundwater.

Injection well Technology is the most effective in capturing surface run off both from plain open loose area or from storm line and filtering in two stages by filtering rainwater through 4 stages of filtration through Silt Trap and Injection well. The silt traps takes care of most impurities in the first stage itself, as it has 40 mm gravels, 10 mm pebbles, charcoal, activated carbon and coarse send and horizontally fixed V wire non clogging SS screen of 500 mm length and 150 mm dia. Rainwater then flows through main Injection well where it flows by gravity through 40 mm gravels, 10 mm pebbles, charcoal, activated carbon and coarse send and vertically placed V wire non clogging SS screen of 500 mm length and 200 mm dia. on the recharge bore well. Air vent from bore well and main well is kept at center. The main well is designed to do maintenance whenever is required. As such the filtration media only needs cleaning once in a year Silt Trap and Injection well. The best technology to have head pressure by the way of water column to ensure fast recharge of ground water and recover the water levels in Aquifer.
