Completion Date: 2010-02-28

Technology Used:

The staff of the School, village youth and the women SHG members will be trained on the day-to-day maintenance and in carrying out small repairs of the Rope pumps.

The field staff of Ekoventure jointly with the SHG leaders will monitor the operation and maintenance of the Rope pump and report in the weekly meetings.

Rope pump is a house hold level pump for drinking water and small scale productive use like kitchen gardening in areas with ground water availability at shallow depths not exceeding 35 m. It can be used as a better substitute for the conventional hand pumps. Hand pumps are mostly used for lifting water from the subsoil water table which is unstable, fluctuating and even depleted during dry period thus making the pump defunct. But, the suction head of the rope pump can penetrate beyond the subsoil water table and reach the shallow water bearing aquifers which are comparatively stable, continuous with higher capillary pressure to render the pumping easier. Therefore, rope pump is more effective and ideal for tapping ground water from the aquifers like alluvial aquifer, Cuddalore sandstone aquifers and ottai aquifers which are found to be reachable even from 10 m up to 35 m. The demonstrations conducted by Ekoventure by installing rope pumps in identical areas of Anumanthai in Villupuram district, Tamilnadu reveals the technical feasibility and community acceptability for rope pumps.

Rope pump design is based on the ancient chain and washer system and consists of endless rope with pistons that fit into a PVC pump tube. At the bottom, the rope with pistons is guided into the pump tube. With a wheel the rope is lifted and the water is elevated to the surface. The rope pump can be produced with locally available standard materials and with local skills and artisans. It is, therefore, simpler to repair, has light and non-corrosive parts and is cheaper to produce.
At the instance of Ekoventure, 3 local workshops Villupuram District, Tamilnadu and at Pondicherry were already involved, trained and made conversant with the production and repairing skills so that facilities are readily available to train, produce and install the required number of rope pump units.

The yield of water at shallow depth is about 30 liters per minute. At the rate of 20 liters per head, for a family of five members about 100 liters of water is required for drinking and cooking purposes. Therefore, one rope pump can cater to the water requirement of about 25 families by operating the pump for duration of about two hours with frequent intervals, assuming the water for external use is met from other sources.

Phases:

Yes, in one Phase for a period of 6 months and maintenance and monitoring will be done after the project completion period by the women SHGs functioning in that village and the School administration with the guidance of the NGO.

Community Organization:

The Rope pumps to be installed in the Schools will be owned by the School and will be maintained by the women SHGs.

The rope pumps installed for the households of women SHGs will be owned by the group and maintained by them. This project is taken up in the first phase in the villages where women SHGs motivated by Ekoventure do exist. The women SHGs in the respective villages have agreed to bear the costs related to the operation and maintenance of the rope pumps.

Government Interaction:

Ancillary activities:

2 locally available workshops will be Trained on production and installation of rope pumps.
