El Boyenar

The community of El Boyenar, located in Region Metropolitana, Santiago, Chile, had limited access to potable water. Several organizations and government entities tried without success to help the community obtain this vital need. Now, as a result of TOHL's engineering, as well as TOHL's Mobile Infrastructure, 58 families now enjoy pure potable water in their own homes. In addition to providing access to water, TOHL also conducted educational workshops and training on water conservation and system maintenance, empowering the community to have the means to sustain the project for years to come.

Materials summary

  • Two HDPE (High Density Polyethylene) storage tanks of 20,000 liters each
  • A 2,500 liter HDPE sedimentation tank
  • Water collection point in the river: composed of a concrete cylinder and various hydraulic components
  • In-line chlorinator and chlorine tablets.
  • Faucets for 58 houses with tubing of ¾¨ diameter
  • 5,000 meters of pipeline with diameters of 85 mm, 50 mm and 25 mm
  • Connections, connections, valves and other hydraulic components

Construction Process

Phase 1
The water source (point A) had to be connected to the central distribution point (point B) close to the community. 

First, the water intake point as well as the sedimentation tank were installed at the water source. Next, the HDPE pipeline was installed using a combination of TOHL's helicopter installation technique and conventional installation techniques. Lastly, the water storage tanks and the chlorine sanitation system were installed on a concrete slab.

Phase 2 
Through a more conventional process, the distribution network with 58 faucets was installed to connect each house.

Training workshops

3 workshops were completed with the community in order to help ensure project sustainability:

  • Payment of a fee for the durability of the system.
  • Education on the responsible use of water.
  • Maintenance of the system from a technical perspective.
