Chittoor, an arid district in Andhra Pradesh, faces seasonal drought. This causes acute water scarcity, leading to very low drinking water availability. Dhan Vayalagam foundation has focuses on developing and renovating traditional water harvesting structures as an effective way to collect rainwater and recharge groundwater, and helps people access water through the summer months. This was done through:

Building Social capital: To establish sustainable local management by building different user groups called Vayalagams and networking them towards water conservation.

Conservation and development of tanks in cascade: Rehabilitation of traditional tanks in a cascade approach to enhance the availability of water for agriculture, livestock, domestic and other uses.

Agricultural development: Introduction of effective water management practices, improved crop yields; and establishing marketing linkages.

Promotion of simple technologies such as rainwater harvesting , biosand filters (to improve water quality) and

Hygiene promotion – demonstration of Ecosan units and hygiene promotion.

Outputs

Around 6 village tanks renovated and rehabilitated. This included:
- De-siltation of feeder channel to improve the inflow of water into the tanks.
- De-siltation of tank beds which created additional water storage capacity of about 13,066 Cu Mts (13.07 Million Lts).
- Tank silt application to crop fields contributed towards enhancing the soil fertility and in reducing the use of chemical fertilizers.
Improved water holding capacity of the tanks and enabled fish rearing activities in these tanks.
Tank rehabilitation significantly contributed to groundwater recharge.
Rooftop rainwater harvesting made a viable option for household water security, with six households adopting this technology.
Over 15 Biosand filters introduced to provide safe water.
Over 12 Ecosan toilets were demonstrated.
Through various development schemes of the government, approximately Rs. 65 lakh was leveraged

The project improved water quality by tackling the fluoride problem in a village in Andhra Pradesh. Existing concerns within the government systems of Chitoor district about fluoride contamination were validated through water quality studies. Several decentralised fluoride mitigation measures were tested during the pilot phase. This helped in the identification of several cost-effective solutions for improving water quality and led to efforts to introduce these measures in the district.

Outputs

Awareness building workshops and trainings conducted for the community and local government to explain the ill effects of high Fluoride concentration in drinking water.
Villagers trained to use field test kits, thus empowering them to independently test the quality of water.
A field-test based report was submitted to the district administration. Based on this the Collector ordered testing of water samples for Fluoride in about 60 villages. This confirmed that the water was found to contain Fluoride above permissible levels.
The MGNREGS programme was leveraged for afforestation efforts to achieve better vegetation and less soil erosion.
Various methods to provide potable, Fluoride free water implemented:

- Rooftop rainwater harvesting systems set up to provide safe water to around 15 households.
- Activated alumina filters installed to provide safe water to around 30 households.
- Jal Nirmal Defluorider Sachet, a new product that removes Fluoride and bacteria, was tested for effectiveness and suitability on a pilot basis in around 5 households.
- Village tank (Cheruvu) renovated (desilting, bund strengthening, etc.) to gain better surface water storage.

In 2009, Vishaka Jilla Nava Nirmana Samiti (VJNNS) took up an initiative in six villages inhabited by landless people. These villages have poor or no access to basic infrastructure facilities like electricity and the government’s water supply systems have failed to work because of improper site selection, poor ground water quality (rich in iron content), poor quality of construction and equipment used. Given these problems, the systems fell into disuse soon after they were constructed leaving the villagers with no option but to travel to remotely located springs to obtain water for domestic use. Even this was not a solution because the water was murky. VJNNS partnered with the community to establish Gravity Flow Water Supply System (GFWS) in these villages to provide sustainable, safe water supply.

Waste water management and sanitation models were introduced and robust mechanisms for community participation were evolved to ensure operation and maintenance of the systems. Structured water quality data and information on water related issues, specific to eastern hilly part of Vishakhapatnam, was disseminated through the India Water Portal. Through this effort, the villages were able to access 24 X 7 water supply.

Outputs

Water quality testing and baseline studies were conducted.
Awareness building workshops and community training was given on aspects of setting up and maintaining water supply systems, water quality, hygiene management etc.
Over 2 lakh leveraged from beneficiary contribution for labour expenses towards construction of the GFWS.
Around 5 mini-water supply projects constructed and 10 mini water supply projects revived.
These systems are properly designed with filter units and provide 24 x 7 water supply.
One bathroom cum toilet constructed as a model which led to adoption of household sanitation including toilets by at least 10% households.
Three community toilets were constructed.
