LAFD News:

Los Alamos Fire Department (LAFD) testing of fire hydrants throughout the community began in May and continues through the end of September. 

The purpose of hydrant testing is to ensure that they will provide an adequate water supply for fire suppression and to flush out sediments that have accumulated in the water distribution system over the past year.

These tests are part of the regular hydrant maintenance program and are done in conjunction with the Los Alamos Department of Public Utilities (DPU).

Residents will see LAFD firefighters and vehicles throughout the community flowing water from the hydrants while they are conducting these tests.

Residents may see some discoloration in their water due to the amount and volume of water being flowed when the hydrants are being tested in their area.

If this is the case, residents should run the cold water spigot located outside their home for a few minutes. This will usually resolve the issue.

It also is recommended that residents avoid washing laundry until the water runs clear. If the discolored water does not run clear after a few minutes, call the Los Alamos Department of Public Utilities Customer Care Center at 505.662.8333.
