Non-Potable Pipeline Project Begins On Arizona Street


Los Alamos Department of Public Utilities’ contractor H.O. Construction, Inc., will commence work on Arizona Avenue this week as part of the Non-Potable Pipeline Project. 

Residents on Arizona should expect to see placement of traffic control devices as well as crews locating existing utilities through “pot-hole” excavation and utility locate paint in the public right of way. 

In the following weeks crews will begin trenching and placing pipe beginning at the east end of Arizona Avenue near Pajarito School and moving west. Some traffic delays may be expected. 

Ingress and egress into homes will be maintained as much as possible. There may be short temporary delays to driveways if work is occurring in front of a home.  No interruption of utility services is anticipated.  

Crews will work 7:30 a.m. to 5:30 p.m. Monday through Friday for approximately three months.

Deputy Utilities Manager James Alarid stated that “this is an important project to improve and enhance the storage of non-potable water. We will convert the Group 12 water tank, just north and west of Arizona, to a non-potable water storage tank. The additional storage will facilitate the ease and convenience of displacing drinking water with non-potable water for irrigating turf areas.” 

The project is identified in the “Los Alamos County Non-Potable Water System Master Plan” prepared by Forsgren Associations, Inc. and accepted by the Board of Public Utilities in September 2013. The plan is available on the County website at
