Water Supply Service Improvement and Extension Project (O&M Phase)

The cities of La Paz and El Alto are provided with drinking water by four independent but interlinked water supply systems (El Alto & Achachicala & Pampahasi & Tilata). These current systems together have insufficient capacity to deliver water supply services to the populations of La Paz and El Alto. Specifically in El Alto and the north eastern hillsides of La Paz the Chuquiaguillo area. It is a challenge for the municipal government and utility companies to provide adequate service to the population in this area. The project concerns reallocation of water resources and the construction of a new independent water supply system for the Chuquiaguillo service area. The main project components include: - raw water capitation and transport, - water treatment plant (max capacity 300 l/s), - transmission main (approx. 17 km), - distribution system (approx. 30 km),- technical assistance to drinking water company EPSAS,- DESCOM: community development and awareness raising activities.The interventions in the Chuquiaguillo system will be implemented in parallel with the construction of the Hampaturi Alto Dam. Once the Hampaturi Alto dam is taken into operation the Incachaca dam which currently provides water to the Pampahasi water treatment plant will be used exclusively for the supply of raw water to the Chuquiaguillo water treatment plant.
