Free fresh, soft and pure water is the original water on the Earth. This is the fundamental source of water from our God father to keep universe live. Rainwater before it flows down to drains or ocean, if harvested in its respective resource can solve such a large problem of water with minimum investment and maximum involvement of common man.
Installation of rainwater harvesting system has been made mandatory by certain Indian states; for other states, the people are feeling socially obligated to have a rainwater harvesting system installed in their premises. And why not! The practice of harvesting rain is highly beneficial, for the increasing demand for water for the ever-increasing population and for the conservation of the environment.
The design of a rainwater harvesting system is fairly simple. For most of the premises and even countries, the components and design are more or less similar. The only change lies in its structuring, its measurements and the use of materials for the components. Deciding over these on your own may become a little complicated since it requires certain expert understanding and calculations. For this purpose, hiring expert services of professional rainwater consultant would be the best option. Let’s us first understand the factors that we need to look in to while planning for rainwater harvesting system:
Factors to consider for rainwater harvesting system:
1) Size of Tank
The size of the water storage tank is of high importance. Though it may seem simple, the decision can only be taken after making certain additional considerations such as the size of the building, location, annual rainfall, demand of the premises, budget, for how long the tank will only be partly full, etc.
2) Appropriateness of the tank for the property
The rainwater harvesting tanks are classified on the basis of material used and installation mode. The neighbourhood may also impose limitations on what sort of tank can be used. For example, on an industrial site, the above-ground tanks can be a matter of concern.
3) Size of the roof or catchment areas
The whole rainwater harvesting system revolves around this one factor- the size of the catchment area. The size of gutters, the capacity of the water tank, the system of pipes, and everything else will be planned once the size of roof or catchment area is determined.
4) Location of Tank
Installing a tank at the appropriate location is important to have a well-connected system and uninterrupted supply of stored water. The roof void of a building is considered to be the ideal location to place rainwater harvesting tanks, but this is usually impossible, as in such a case, the guttering would generally be located below the level of the tank. Also, the weight of the tank may pose additional problems. Another difficult decision is regarding the placement of the tank- above-ground or underground. This requires considering additional factors such as weather conditions of the place.
5) Rooftop rainwater filter :
Level of rainwater through the filter unit and the tank itself has an impact on the downstream drainage system, which is again, a vital consideration for installation of the RWH system. Hence, it must be considered carefully.
6) The potential demand
The intention of rainwater is to provide an incessant water supply for the occupants. Hence, the potential is another substantial factor. The potential occupancy of a building is the key here. While insufficient water storage for higher demand is a problem, similarly, having a large storage capacity with only minimal water level to provide supply to, say, 5 or 6 people, is again a wastage of resources.
7) Future demand
The design of the rainwater harvesting system must keep scope for the future enhancements, based on the increasing or decreasing demand for water supply, in the future.
8) The Overall drainage scheme
If the drainage system of a site is intended to meet a peak discharge limit, the rainwater harvesting tank must be designed accordingly. Also, in a household, the structure of sewer pipes must be studied to avoid any collision with the rainwater harvesting conduit system.
For the aforementioned factors, a bespoke solution is required, for your rainwater harvesting needs. A rainwater consultant is what you need, to guide you with the best solution.

What is water Conservation?
Water Conservation is the practice of using water efficiently to reduce unnecessary water wastage. Water conservation also means to save fresh rainwater as fresh and clean water is a limited resource, as well as costly one. As a homeowner, you’re probably already well aware of the financial costs of inefficient water use. Conservation of this natural resource is critical for the environment-and our wallets.
Rainwater harvesting means collecting the rain water into the natural reservoirs or man-made tanks. It is the technique to collect and store rainwater for various purposes in the future. The most common and easy method of rain water harvesting is the rooftop harvesting. Using this technique we can collect lots of clean rain water in the rainy season. It can be stored for long time for the household purposes like gardening, livestock, and irrigation, etc.
Why to start rainwater conservation?
It helps in reducing water supply loads and electricity bills of municipality, improve free water supply, crop production in rural areas, and thus lead to food security.
Rain water harvesting system helps in reducing the insecurity of households or individuals in the rural areas.
It provides easy and low cost water supply in the lack of water areas thus helps in food security and income generation.

run a race of Rainwater harvesting.”
