A wonder farm in Kerala


“Since 2007, this research station has gone from being a sleepy government facility to an engine of innovative agricultural practices – some local, some with far-reaching implications. Much of the credit for this energy and vision goes to Prasanna Rajendran, 53, who heads the ARS with the designation of assistant director of research.

Rajendran’s success has been such that the ARS’s annual income is Rs 2.56 crores. For next year, it has set a target of Rs 3 crores.

Compare that to Kerala Agriculture University (KAU) which earns Rs 8 crores annually from 3,500 acres. The ARS with just 25 acres adds Rs 2.56 crores to the KAU’s kitty.

What has led to this transformation? Rajendran attributes it to “just a little common sense and team work”. He adds: “Whatever we’ve done here is possible in any other research institution.”

Started in 1963, the Anakkayam ARS was once a cashew research station with 25 acres of rain-fed dryland. Only one scientist and five labourers worked here. Every summer, drinking water had to fetched from outside. The station’s annual revenue was a paltry Rs 4.92 lakhs. It had been all but written off.

Today ARS trains youth in agriculture, works with self-help groups (SHGs) and produces a variety of fruits and vegetables, some of which are processed and sold.”

Rainy filters for Rain water harvesting


`RAINY’ First of its kind Dual Intensity Rainwater Harvesting Filters with self cleaning and auto flush out arrangements.

‘RAINY’R Dual Intensity Rainwater Harvesting Filter™ is the result of over 10 years Continuous R&D done by the team of FARMLAND RAINWATER HARVESTING SYSTEM, by studying the pattern of rain fall in rural and urban India, intensity of rainfall, type of houses, pipeline used for rainwater outlets, re utilization, recharging of ground water and Tube well etc. In the past decade we have witnessed phenomenal changes in global weather patterns. The unpredictable and erratic weather patterns have resulted in torrential down pours and rainfalls of very high intensity. These heavy duty Dual Intensity Rainwater Harvesting filters are so designed; keeping in mind the capture of rainfall loads varying from 5mm to 75mm/hour without affecting the efficiency of filter and the operating required less than 0.06 kg/cm2 (2 feet) so the filter can perform even in low Roof areas. The design, stability and filter function efficiency is directly proportional to the intensity of rainfall. Different models of filters were set in place to capture rainwater from varied rooftops. This brought in affordability, to all cross sections of households and Industry.

Rainy filters are designed with self cleaning mechanism and can be fixed to the wall by connecting Rooftop rainwater drain pipes. The rainwater along with dirt particles enters into the inlet of filter through the hollow pipe tangentially to the filter housing and rotating slowly along the periphery of upper housing so as to flow into the SS 304 filter element placed in lower housing of the filter unit in angular motion at specific velocity, which creates cohesive force and segregates dirt particles and clean water individually. However when the intensity of rainfall increases the high volume of water moves in circular motion with high velocity in the upper housing and creates a centrifugal force. In both situations, involving low and high intensity of rainfall , the working principle of the filter based on cohesive and centrifugal force respectively, aids the filter element to divert clean water into the cistern/ recharging well and simultaneously flushes out automatically sand, debris, and dirt particles through the drain outlet.

Alaknanda – rain water harvesting systems


Rain is an ultimate source of all water resources on earth. Therefore, all water in use is, in effect, rainwater-harvesting systems. The process of rainwater harvesting would include catching rainwater, filtering or treatment and directing it to storage or recharge. Storage could be in tanks, ponds or lakes wherever appropriate and recharge of ground water through well/tube well/bore well or a specially designed well. Rainwater harvesting or rooftop rainwater harvesting is the technique through which rainwater is captured from roof catchments and stored in tanks/reservoirs/ground water aquifers.

The miracle of Hiware Bazar


“Ours was a simple village with happy families. But lack of water turned our fields barren,” remembers Laxman Pawar, 71, a farmer. “Out of desperation, people started to drink, gamble and fight. Liquor had ruined us. When the illicit dens were closed, we knew there was hope.”

One of the first things the sarpanch did was water conservation and management as it helped farming and brought in some money. He got the villagers to voluntarily help in rainwater harvesting. Soon, the villagers built 52 earthen bunds, two percolation tanks, 32 stone bunds and nine check dams. “We used state government funds. The volunteer labour programme cut costs and also ensured quality work. It was as if we were building it for ourselves and for our children,” he says.

The idea was to harvest every raindrop as it fell. Being in the rain-shadow region, Hiware Bazar received just about 15 inches of annual rain. Ponds and trenches stopped rainwater from flowing out of the village. After the first monsoon, the irrigation area increased from 20 hectares to 70 hectares. “In 2010, the village got 190 mm of rain, but we managed well because of water management,” says Habib Sayyed, who works on water issues in the village.

Water management helped them harvest multiple crops. Before 1995, there were 90 open wells with water at 80-125 feet. Today, there are 294 open wells with water at 15-40 feet. Other villages in Ahmednagar district have to drill nearly 200 feet to reach water.
