CRS is implementing a project to rehabilitate impluvia (underground water catchment basin) with local PVC liner. It will also put in place a management committee, which will be trained after rehabilitation as well.

Catholic Relief Service (CRS) is implementing a project (multiple use of low cost water technologies) funded by OFDA (USAID funding). In the frame of that project PRACTICA has tested with success the rehabilitation of impluvia with local PVC liner : rehabilitation costs around € 1400 and takes 5 days (see picture).
The project idea is to extend the practice of this innovative approach in partnership with CRS beyond their project area.
Rehabilitation of new impluvia with PVC liner
• To put in place a management committee prior to rehabilitating impluvia
• To make the rehabilitation of impluvia with PVC liner
• To train and guide the water committee after rehabilitation
• To equip and train private enterprise
• To select and to equip 2 private enterprises
• To give technical training on the rehabilitating process
• To invite to the technical training other international NGO’s (Gret & Adra), active in the project area
Beneficiaries will participate in the rehabilitation, including repair and maintenance. This will ensure maximum benefit from the project’s investments in local infrastructures.

Context

In the south of Madagascar the aquifer has a high salinity level. Storage of rain water with underground water catchment basin (impluvia) is the main practice to get fresh water. During the past 30 years more than 500 impluvias have been constructed : 50 % are not functional, of 25% half of the volume is available. The construction cost is around 6 000 €/ impluvia and it takes about 1 month to complete.

CRS will work with the targeted communities to create community water management committees where these committees do not already exist. CRS will also build the capacity of the community to manage their own water resource : development of water management plan. In addition CRS will give regular follow up on how the water committees implement their plans, and if they are holding their meetings regularly. The same holds for the guidance of the trained private enterprises.
