What do Rainwater Harvesting Consultants do?

Rainwater harvesting consultants or Rainwater Harvesting Contractors like us are the people who design and implement a rainwater harvesting system that is tailored to suit your needs. The primary goal of a rainwater consultant in to eliminate any source of runaway rainwater. To do so, all the potential runaway sources must be directed into a percolation pit or a storage tank. Rainwater harvesting can be broadly divided into basic RWH and advanced RWH. Although both types of Rainwater harvesting aims in saving runaway rainwater, the process of how it is delivered is different.

Basic Rainwater Harvesting

Basic rainwater harvesting systems do a perfect job in eliminating run away rainwater. Most houses or buildings have a terrace which acts as the catchment area. If you do not have a terraced roof, don’t worry, rainwater harvesting contractors in Chennai will install catchment pipes to collect rainwater. The collected rainwater will be then directed to the percolation pit. Percolation is a pit that is dug and filled with metal gravel and sand. The percolation pit is covered with a concrete slab. The purpose of the percolation pit is to recharge the soil beneath with the rainwater.

Advanced Rainwater Harvesting

In Advanced Rainwater harvesting, in addition to the above basic components, extra components are added to make it more efficient. The water from the catchment area will be transferred into a storage tank. Rainwater consultants in Chennai will build you a sump (underground storage tank) or fit your home with a readymade storage tank. The collected rainwater, before being stored, undergoes a simple filtration process. Rainwater harvesting contractors in Chennai will provide you with a ‘rainy filter’ to filter the rainwater before being stored. The catchment water can also be directed into the bore well. Directing water into the bore well allows you to directly recharge the aquifer. 

In addition to the above mentioned basic and advanced types, Professional Rainwater Consultants are also available who dedicate their work to plan on a large scale and they work with civic authorities. They work closely with the Government machinery to bring about policy frameworks in conservation of rainwater and work towards implementing the same.

Tamil Nadu’s step towards making Rain Water Harvesting Systems Mandatory

Tamil Nadu is a pioneering Indian state that mandated setting up of Rainwater Harvesting Systems way back in 2001 when a water crisis hit the city of  Chennai very similar to the one we are experiencing now in 2019. As a measure to increase the ground water table, the then Government under Selvi J. Jayalalitha made it mandatory that every built structure have a working RWH. (more…)

Traditional Rainwater Conservation in Tamil Nadu

The 2019 water crisis in Chennai has made us realize the importance of saving water more than ever. Water, as we all know, is a finite resource without which our planet would be a barren wasteland. Today with our increasing population it would be logical to say that our water consumption has also increased. And with increasing demand and lesser supply, water scarcity arises. Our ancestors who had foreseen the potential dangers of water scarcity had developed methods to conserve water that was suited for the varied terrain of the Tamil-speaking kingdoms.

Traditional Rainwater Conservation methods of Tamil Nadu

Eri

There are no perennial rivers in Tamil Nadu except the Thamirabharani River which flows through Thirunelveli district. And so, several hundred years ago a simple system was devised to utilize the rainwater to the fullest. An Eri or tank system is one of the oldest forms of water conservation systems in India. Many Eris are still in use in Tamil Nadu and play an active role in irrigation. They act as water reservoirs and flood control systems. They prevent soil erosion, recharge groundwater, and prevent wastage of runoff water during heavy rainfall.

Kudimaramathu

Kudimaramathu is one of the old traditional practice of stakeholders participating in the maintenance and management of irrigation systems. During earlier days, citizens of a village used to actively participate in maintaining the water bodies of their village by deepening and widening the lakes and ponds and restoring the water bodies back to their original form. The silt, rich in nutrients, collected in the process would be used by the farmers themselves in their field. A sense of collective ownership ensured the continued survival of the water bodies.

Oorani:

Oorani’s are very similar to Eri’s. But unlike an Eri which supplies water to irrigate fields, oorani is used to provide drinking water. Oorani’s are much smaller and are shallower than Eri’s. Oorani’s catch rainwater and the water stored by them is more preferably used for drinking.
