Project Overview:
The Navajo Engineering & Construction Authority (NECA), in partnership with Navajo Area Indian Health Service (IHS), awarded Riley Engineering a contract for civil engineering design support for the Cisterns and Individual On-Site Wastewater Disposal Systems for 127 Homes project.
The main objective was to provide water & wastewater services via septic systems and water tanks to homes across multiple Chapters on the Navajo Nation. The scope of work included performing initial homesite assessments, archaeological and biological clearances, and designs for cisterns and on-site #wastewater disposal systems.
Riley Engineering was pleased to work with NECA, IHS, Ninyo & Moore Geotechnical and Environmental Sciences Consultants (soil sampling and testing), and WestLand Engineering & Environmental Services (archaeological/biological clearances) to help families get closer to having running water in their homes.
