2.1 Courte description de la Technologie

Définition de la Technologie:

Stone masonry reservoir linked with roof rain water through a pipe scheme to provide safe drinking/low cost water supply in the remote areas.

2.2 Description détaillée de la Technologie

Description:

Kishendeh district is extremely mountainous with low precipitation and with a shortage of water storage facilities. Underground reservoirs, called kandas, traditionally serve as water storage, catching rain water over the two/three wet months of the year for use throughout the rest of the year. The kandas tend to run out of water before the next rains come, and tend to be positioned very far away from villages in difficult to reach spots. Alika village, where this technology is implemented, suffers from the scarcity and unavailability of irrigation, livestock and even safe drinking water. Scarcity of water during the summer season makes the lives of the community members more difficult and results in their immigration from the village in the past.

Purpose of the Technology: To ease water shortage in the target community, in addition to the introduction of drought-resistant crops and soil and water conservation techniques, People in Need (PIN) has applied roof rain water harvesting technology in Alika elementary school, Alika village, Chakana cluster. The site where this technology has been applied belongs to the state. The water use right is common and poor families that do not have access to kandas are given priority for using this reservoir. The school and households near the school use this water for drinking and washing.

Establishment / maintenance activities and inputs: The project started in October, 2014 and was completed in April, 2015. For the establishment of the roof rain water harvesting technology the following inputs were used:

360 square meter tin was used to cover the roof. The pipe system is 45 meters in total. Three inch PVC pipes as well as elbows and T-joints were used. The water reservoir’s dimension of 0.80x0.50 m stone masonry foundation and 0.60x1.50x24.4 m wall; The dry stone masonry is 30cm wide; the surface of the reservoir, reinforced concrete (RCC) is 15cm wide. The reservoir was plastered with water proofing. The roof of the reservoir was constructed using wooden sketch covered with hard plastic material.

141 person/day were required for accomplishing this project. The establishment cost was 5,296$. The total value of community contribution is 7,500 Afghani/145 US$. Excavation by community members of a 50 m3 area is valued at 20,000 Afghani/385 US$. Thus the total community contribution is 10% of the total costs.

The head master of the school assumes the responsibility for maintenance. The reservoir needs to be cleaned five times a year, this is a low cost exercise. In the rainfall season it needs to be done once a month. Cleaning can be done by one person. The estimated cost for the maintenance is 500 Afghani or 10 US$ and is fully contributed by the community members.

Natural / human environment: Balkh province has a semi-arid climate and receives about 280 mm rainfall per year. The main economic activities are agriculture and livestock. The community members of the Kishendeh district have a low access to health services, employment, roads and transport and to drinking water and sanitation. Lack and scarcity of water in this village has caused many internal displacements as well.

6.7 Points forts/ avantages/ possibilités de la Technologie

Points forts/ avantages/ possibilités du point de vue du compilateur ou d'une autre personne ressource clé
Provides low cost safe drinking water to the community members (Alika school and HHs who lives near the reservoir free of charge). Further more it provides irrigation water for the kitchen gardens in some extent. How can they be sustained / enhanced? Safe drinking water can be easily available during the winter season but during the three months of summer the water should be carefully used only for drinking.
Requires minimum maintenance when constructed properly. How can they be sustained / enhanced? Pipe scheme, roof coverage area of the reservoir, should be cleaned, if any leakages occurs in the pipes or reservoir , they should be sealed.
Application of the technology has provided the chance of having leisure time for the families. How can they be sustained / enhanced? Families and community members should use the water effectively.
Roof rain water harvesting technology has supported the community members, economically. How can they be sustained / enhanced? Community members should take active participation in the maintenance of the reservoirs.

6.8 Faiblesses/ inconvénients/ risques de la Technologie et moyens de les surmonter

Faiblesses/ inconvénients/ risques du point de vue du compilateur ou d'une autre personne ressource clé	Comment peuvent-ils être surmontés?
This technology is difficult to be applied without external financial support.	Adoption of local materials should be promoted and as well as reservoirs be properly cleaned after the heavy rainfalls.
Technical knowledge is required for the application of this technology.	The technical knowledge should be transferred to the extension workers or local people to provide technical support in the future.
During the drought season with no rain fall enough water cannot be harvested inside the reservoir.	Water can be transferred to this reservoir through water tanks from other villages.
Social conflicts can occur during the distribution of water.	Meetings and awareness sharing events should be held. Water in keeper can be introduced by CDCs for the distribution of water.
