Wastewater systems condition and capital plan
Los Alamos County
Summary
Sewer backups keep occurring at a steady rate, driven by old clay pipe at the bottoms of neighborhoods, root intrusion, and cheap flapper-style backwater valves that fail 40-50% of the time. Staff plan a fall RIP-loan program to replace problem lines and a public education campaign.
