The average annual rainfall in Assam is 2818mm, of which Guwahati alone receives 1698mm. However, the impact of rainfall in the state is zonal and not uniform throughout the state. As a result some areas are inundated, others remain rain-deprived. At this point it is wise to invest in rain water harvesting.
Assam demonstrates huge potential for successful rainwater harvesting. If implemented on a larger scale, it could be instrumental in curbing problems like floods, soil erosion, drought, water scarcity, and water-logging. This apart, the collected water could also be used for various activities like agriculture, animal husbandry, infrastructural development etc.
Since Large-scale Rainwater Harvesting won’t be a reality without the active participation of citizen at large, Government of Assam solicits your valuable and innovative suggestions covering ways to take rainwater harvesting from domestic to public setups.

You can know more here about the different types of RWH systems for different types of homes, as recommended by the Government. You can also visit the beautiful rainwater harvesting theme park at Jayanagar in Bangalore or the Rain Centre at Chennai where one can see several models on display and learn about different rainwater harvesting methods. A free consultation is also available with engineers at these places for a basic rainwater harvesting design. So this time, when it rains, your homes w

Rainwater that falls on the rooftop, be it flat or slanting, can be made to run through a pipe to a storage facility like a sump or a tank. This water can be filtered to purify the larger particles before being stored in rainwater harvest (RWH) tanks. By using stored rainwater for washing cars and watering gardens, the use of underground water can be minimised. A win-win system for economy and environment, this also helps in saving energy and keeps the energy bill to a minimum.

If you are looking for a fast DIY way to collect rainwater without much hassle, rain saucers form a great free standing rain collection system which fill up surprisingly fast. Looking like an upside-down umbrella, the rain saucer unfolds to form a funnel which fills the containers with rainwater. Since this easy-to-deploy system catches rain straight from the sky, it also decreases the chances of contamination. Here’s how you can make one.

Setting up a splash block is a great idea to divert the flowing rainwater away from the structure’s foundation.It is a piece of concrete or plastic of a roughly rectangular shape, and is placed below the downspout that carries rainwater from the roof of a house during rainfall. It absorbs the force of the water that is getting diverted from the roof, and also prevents holes from being dug in the garden due to the eroding force of the pouring water. Here’s how to make one yourself.

A recharge pit for borewells is also a good idea as it pushes back the surface water into the groundwater system. Usually, a recharge pit is one metre in diameter and six metres deep, lined with concrete rings having perforations. These perforations let filtered and de-silted water seep from the sides increasing the groundwater table.

Rooftop rainwater is led through pipes with a filter at the end to open dug wells for replenishing underground aquifers. Based on this idea, the ‘Mazhapolima’ (bounty of rain) Recharge Project of Thrissur was born. As a result, today, not only is there abundant water in summer, there is also reduced salinity, turbidity, and colour in the well water.

Rain chains are not only beautiful, simple to make requiring few tools and materials, but also a more attractive alternative to standard PVC (polyvinyl chloride) pipe downspouts. These fun, fashionable and environment-friendly accessories help avoid the runoff by transporting rainwater from the collecting pipe downwards to a drain or to a storage container

A rain garden is a sunken landscape that uses native plants, local soil, and mulch to remove pollutants from water, and allows it to percolate into the ground. It’s easy to create, looks good all year-round and has a positive impact on the environment. Here’s how to make a rain garden in your own backyard.

The easiest way to harvest rain is through a rain barrel (make your own from a large trash can or an old drum) linked to a pipe fitted to collect rainwater from the rooftop and verandah of the house.To prevent the barrel from becoming a mosquito breeding ground, fasten a tight-fitting top to it, and screen the ends of the downspouts leading into the barrels. Or simply add a tablespoon of vegetable oil to the stored rainwater.
