Drought, Scarcity &
The Future

As per United Nations by 2025, 1.9 billion people will face absolute water scarcity & two-thirds of world population would have difficulty to access clean drinking water, while in India, it is predicted by 2030 - 40% of the population will not have access to clean drinking water and cities like Delhi, Chennai, Bangalore, etc shall face severe drought.

Harvesting Rain Today,
Saves Our Tomorrow

India receives annual rainfall of 3,000 to 4,000 billion cubic meters on an average, Which gives us an opportunity to recharge while meeting the growing water demand, but unfortunately we fail to utilize almost three-fourth of water we receive from the sky.

Invest for our Future

Rainwater harvesting & recharging is the permanent & easiest solution to our water crisis. Lets inculcate ourselves back into our culture of respecting & conserving rainwater. Lets start today by sowing our own seed by harvesting rain and reap the benefit year after year with water abundance.


The revolutionary rainwater filter - Aquifer, filters multiple pipes at a single point, it comes with an option of a unique 3 Layer Filtering system. The Rain water stored through Aquifer Filter can take care of your domestic water requirement for most part of the year and can significantly increase your water catchment efficiency, even at high flow rates (95% at 10 litres per second in wet systems).



ECORASTER is one of the most reliable and successful surface reinforcement systems. It is an alternative to Concrete & Asphalt, providing durable, safe and permeable surfaces that can withstand car or truck traffic movement while retaining the natural water retention properties of the ground, it also has a unique drainage and load properties. With ECORASTER, you are choosing a quality, TÜV approved, "Made in Germany" grid that has been chosen worldwide by planers, communities, and builders for more than 20 years



Resilient surfaces that need to be easy to clean can be constructed with ECORASTER BLOXX. Absolutely sealing free but with the advantages of a paving stone. On request, rubber “stones” can also be inserted in the BLOXX instead of concrete elements. In this way you get an even quieter , highly resilient surface that is perfectly protected from cold and noise. ECORASTER BLOXX works like a retaining frame for the concrete slabs and features an integrated anti-clog drain channel. As well as quick installation, this ensures consistent drain characteristics and allows rainwater to drain away quickly.

"Nowadays, we all are running behind green. Thanks to water tree for their amazing product basic, elite & grand versions of Aquifer. This product makes us to harvesst rain water and reduce dependency on ground water which not only saves us but also for our future generation too.""




RWH is the technique of collecting, storing and distributing rainwater for multiple uses. The collected water can be stored for direct use or diverted for bore well/groundwater recharge. In simple terms it is a way to capture the rainwater when it rains, for later use.
RWH can be done in any space where there is a catchment area in the form of a roof or open space to capture the rain. It is a simpler affair, where even a rain barrel can serve as a storage unit for rooftop RWH. Individual homes and farmers have successfully implemented this easy and eco-friendly method of augmenting household-level water availability and to transform a barren piece of land into a self sustainable, lush green farm respectively.
The rainwater harvested depends upon the catchment area, the rainfall pattern and the drainage/ collection system used. To understand better, lets take the example of a house in Delhi with a terrace area of 100 sqm, taking the average annual rainfall in Delhi as 600 mm, and assuming 70% harvesting efficiency: Volume of water harvested = 100 x 0.6 x 0.7 = 42,000 litres Which is more than twice the annual drinking water requirement of a 5-member family, whose average daily drinking water requirement is 10 lpcd.
The rainwater that falls on the roof is pure, but since it comes in contact with various surfaces on its way to the storage units, some dust and leaves may be present in it. This can be reduced by sweeping the terrace before the rains and boiling the water before consumption. Various filters can also be utilised to remove such suspended pollutants from the rainwater collected to make it safer for consumption.
The benefits include:
  • Flood mitigation: It will help the roads from flooding. When the water is not allowed to leave the premises, the chances of it choking up the roads are minimal.
  • Increasing groundwater levels.
  • Greater water availability:
  • Prevents soil erosion and flooding especially in urban areas
As per the law, for plot sizes of 40x60 sq.m or more you need to store or recharge 20 litres for every sq.m of roof area and 10 litres for every sq.m of non-roof (ground surfaces such as parking, backyard) area. For e.g. if your home has about 100 sq.m of roof area, and about 50 sq.m of non-roof area, then you will need to create capacity for at least 2500 litres of water. If you are using a 1000 litre tank to store rainwater for immediate use, you can connect the overflow to a 4000 litre (3 feet x 20 feet) recharge well.
