Technical Support for Community implemented projects

San Juan River Navajo Irrigation Projects Lateral Conversion Project

Location: Shiprock, NM

Year: 2017-2019

Project Summary:
The San Juan River Dineh Water Users, Inc. (SJRDWU) is converting fifteen secondary earthen irrigation laterals (totaling 182,917 ft) into underground pressurized pipeline.

This will improve water quality in the San Juan River.

The SJRDWU will complete the project using their own equipment and hiring and training members of their community to perform construction labor tasks. 
By using local resources the association is able to save significant costs over hiring an external construction contractor. Cost savings allow the association to convert more ditches into pipeline.

By hiring local people to perform the works, the project is able to stimulate local household income and provide technical training to its employees. 

Hiring local people will make the Irrigation System more sustainable and will strengthen the administrative and tecnical capacity of the Water User Association.
