If there is a ‘3^rd World war, it is said, the war will be for drinking water’.

Water resources are becoming scanty. Rain water harvesting is THE solution to this problem. We are specialized in both long term and short term Rain water harvesting projects. Roof top rain water harvesting is the short term and ground water recharging is the long term plan.

Rain water harvesting is the main programme under this sector. To assure drinking water to all, harvesting the abundant rain water is the ideal mechanism. We have constructed thousands of rain water harvesting systems in various parts of country as in state of kerala, Andhra Pradesh, Karnataka and Tamilnadu

1. Rainwater Harvesting

Kerala gets an average of 250 to 300 cm rainfall, annually. Due to the steep terrain, the major chunk of the rainwater falling reaches the Oceans within a span of 48 hours. This rainwater if harvested, can be used for drinking and cooking purposes during the stringent summers. Rainwater is harvested from the rooftops of buildings by channeling through chutes. Passing through layers of sand, gravel and activated carbon filters it before it gets collected in the harvesting tank. It is a proven fact that rainwater thus collected and kept without contact with air or sunlight can be retained pure for a year. Thus collecting rainwater at every household is the most economical and feasible remedy for shortage of drinking water.

For an individual, per day, 20 litres of water is needed for cooking and drinking purposes. Thus for a family of 5, around 100 litres of water is needed per day. Hence 10,000 litres of rainwater can suffice the need for drinking water for a family of 5 for a period of three months. In a place, which gets an average 200cm of rainwater annually, a surface area of 8 sq.m is enough to fill a harvesting tank of capacity 10,000 litres in 8 days. The cost per litre on rainwater harvested in a ferro cement tank is around 2 rupees less than that from a synthetic tank. Moreover, the technology is eco-friendly. The cost is further reduced if the tank is built underground.

2. “Varsha” – Rainwater Harvesting Scheme

The project was undertaken by us under the aegis of kerala water authority (KWA), govt. of kerala envisaging construction of ferro cement rain water harvesting systems in the districts of ernamkulam, alleppy, kottayam, thiruvananthapuram and pathanamthitta. through this project we have covered more than 30,000 families. introduction of a new technology in government sector-ferro cement technology-is one of the indirect advantages of the project. we have constructed rain water harvesting systems in more than 500 governemnt institutions and schools. the largest single rainwater system we have constructed is having 200000 ltr capacity.

Other water management programmes we implement are WGDP (western ghatt development program), NWDPRA (national water development project under rain fed areas) and RAINS (rainwater harvesting awareness implementation network system), Jalanidhi of KRWSA under the world bank project

3. Watershed Management

The Andhyodaya's one of the servicing area is the implementation of the watershed and its management. We have constructed many watersheds effectively, an example is Assamnnur Panchayat. A watershed is a basin like landform defined by peaks which are connected by ridges that descend into lower elevations and small valleys. It carries rainwater falling on it drop by drop and channels it into soil, rivulets and streams flowing into large rivers and in due course sea.

Watershed management is the the process of creating and implementing plans, programs, and projects to sustain and enhance watershed functions that affect the plant, animal and human communities within a satershed boundary. Features of a waterhsed that agencies seek to manage include water supply, water quality, drainage, stormwater runoff, water rights and the overall planning and utilization of watersheds.

1. RAIN WATER HARVESTING TO AUGMENT GROUND WATER RESOURCES

1.0 Rain Water Harvesting is the technique of collection and storage of rain water at surface or in sub-surface aquifer, before it is lost as surface run off. The augmented resource can be harvested in the time of need. Artificial recharge to ground water is a process by which the ground water reservoir is augmented at a rate exceeding that under natural conditions of replenishment.

2.0 NEED

To overcome the inadequacy of surface water to meet our demands.
To arrest decline in ground water levels.
To enhance availability of ground water at specific place and time and utilize rain water for
sustainable development.
To increase infiltration of rain water in the subsoil which has decreased drastically in urban areas
due to paving of open area.
To improve ground water quality by dilution.
To increase agriculture production.
To improve ecology of the area by increase in vegetation cover etc.

3.0 ADVANTAGE

The cost of recharge to sub-surface reservoir is lower than surface reservoirs.
The aquifer serves as a distribution system also.
No land is wasted for storage purpose and no population displacement is involved.
Ground water is not directly exposed to evaporation and pollution.
Storing water under ground is environment friendly.
It increases the productivity of aquifer.
It reduces flood hazards.
Effects rise in ground water levels.
Mitigates effects of drought.
Reduces soil erosion.

4.0 DESIGN CONSIDERATIONS:

The important aspects to be looked into for designing a rainwater harvesting system to augment ground water resources are:-

Hydrogeology of the area including nature and extent of aquifer, soil cover, topography, depth to water level and chemical quality of ground water.
The availability of source water, one of the prime requisite for ground water recharge, basically assessed in terms of non-committed surplus monsoon runoff.
Area contributing run off like area available, land use pattern, industrial, residential, green belt, paved areas, rooftop area etc.
Hydrometerological characters like rainfall duration, general pattern and intensity of rainfall.

5.0 POTENTIAL AREAS

Where ground water levels are declining on regular basis.
Where substantial amount of aquifer has been de-saturated.
Where availability of ground water id inadequate in lean months.
Where due to rapid urbanization, infiltration of rain water into subsoil has decreased drastically and recharging of ground water has diminished.

6.0 METHODS & TECHNIQOES

The methods of ground water recharge mainly are:

Urban Areas

1. Recharge Pit

2. Recharge Trench

3. Tubewell

4. Recharge Well

Rural Areas

8. Groundwater Dams / Subsurface Dyke

We started implementing’VARSHA’ a Kerala Govt. program of Roof top rain water harvesting using “ Ferrocement technologies” in the

year 2002 by now we have covered nearly 30,000 families in the state.

Ferrocement Technology

This technology is an economical, efficient, and easily adoptable one depending on the topography of the location where it is implemented. The word ‘Ferro’ is coined from Ferrous (meaning Iron). This technology took its birth in the year 1848 in the hands of Joseph Louis Lambert, a French Engineer. He designed a boat by cement-plastering both sides of thin iron wiremesh. Being found the boat strong and useful, this technology perpetuated as ferro cement technology. The exercise of this technology has now become very common. Using this discipline, houses, wardrobes, tables and chairs, water tanks etc. are being constructed now.

Ferro Cement technology is presently being widely used in the construction of water tanks. Majority of the tanks built using this principle is circular in shape. The average thickness of the wall will vary between 3cm and 10cm. The wiremesh used in these structures distribute the hydro pressure to the entire structure thereby reducing the weight. This system has set its root in Kerala also. In Kerala, ferro cement tanks are used mainly for roof top rainwater harvesting.

The Andhyodaya is one of the pioneers in the country in implementing organized roof top Rain Water harvesting Programme. 'VARSHA', a Kerala govt.sponsored Programme was a success only because of the intervention of our organization. Under 'VARSHA' rooftop Rain Water Harvesting in Ferro cement tanks was implemented in 4 districts of the state viz, Ernakulam, Alappuzha, Kottayam and Trivandrum. This project was launched by the state govt.in collaboration with Kerala Water Authority implemented by our organization in the year 2002. Ferro cement tank of 5000 and 10000 liter capacities were constructed under the programme for the benefit of Below Poverty Line (BPL) families. These rooftop Rain Water Harvesting Ferro cement systems have a capacity to harvest about 3 cores liters of Rain Water during rainy week. That means, in a rainy season, these systems can harvest a minimum of 15 cores litters of Rain Water. Besides VARSHA, we are also undertaking rooftop Rain Water Harvesting for the govt. buildings and institutions.

We have a trained and effective infrastructure to take up any size of rain water harvesting projects anywhere in the World. Comprising of Engineers, Co-ordinators, Supervisors and Technicians.

RENEWABLE ENERGY PROGRAMS

Conventional energy source's are getting exhausted fast. Unlimited needs and limited resources is the major problem facing by the entire world. So, the development of renewable energy is very important in this time.The Andhyodaya is a forerunner in the area of propogation and innovation of renewable energy projects through out India. We have technical expertise and efficient personnel to implement any size of both solar thermal and photovoltaic energy programmes. Installed capacity – Solar thermal = 200,000 LPD installed capacity – photovoltaic = 38,000 systems.

The World is in an energy crisis. Renewable energy sources are the only solution.The Andhyodaya is introducing various programmes regarding to this problems, they are as follows.

1. Biogas Extension Programme

As the name itself suggests, a biogas plant uses biowastes to garner domestic fuel. The principle behind this is anaerobic digestion. In this method, the digestion of organic matter is carried out in the absence of air in a deep tank. During the process, anaerobic bacteria convert organic solids to methane, carbon dioxide, hydrogen sulphide, ammonia etc. The degradation of the organic matter takes place in two stages. The first stage involves the acid forming bacteria, which hydrolyses the waste into shorter chain organic compounds like organic alcohols, acids and ammonia. In the second stage, methanogenic bacteria convert these intermediate products into gases. Biogas plants are based on the anaerobic technology, which serve dual purpose of reducing environmental pollution and generating energy.

BIOGAS Biogas_2

The Andhyodaya has constructed more than 230000 domestic biogas plants and 1200 institutional biogas plants. We are one of the project partners of the ANERT, Govt. of Kerala State Nodal Agency for Renewable Energy Programme. We also join hands with the Khadi Village Industries Commission (KVIC) in implementing all types of renewable energy programmes in the state of Kerala. In constructing biogas plants we mainly consider rubber latex waste water, cow dung, piggery waste and kitchen waste as the raw materials.

Subsidies are reached to the beneficiaries from Ministry of New and Renewable Energy (MNRE), Govt. of India and Agency for Non-Conventional Energy and Rural Technology (ANERT)

To begin with, the tank should be filled almost completely with fresh water. Then slurry from a gobar gas plant or fresh cowdung slurry is added to the extent of one percent of the total volume of the plant. The organic waste is allowed to pass through the inlet into the bottom of the digester. Since there is no oxygen in the digester, the waste mixture ferments and produces biogas. The gas gets collected in the gas storage dome and is allowed to flow out through a pipeline to the point of its use. Cowdung, kitchen waste and other organic matter could be used in the biogas plant to increase the efficiency of gas generation.

Biogas plant – is a farmer friendly, both urban and rural friendly, renewable energy technologies. It’s a cost effective and eco friendly mechanism to avail :

- Cooking gas

- Lighting

- Organic manure

- Bio pesticide
