5. ALL WATER MAINS SHALL BE INSTALLED WITH A MINIMUM OF 36 INCHES OF COVER.

Development Review Committee Meeting · 2026-04-15 · agenda_item

This civic agenda item concerns proposed water main installations and upgrades. The project requires all water mains to be installed with a minimum of 36 inches of cover and all installation, testing, and field inspections must conform to AWWA standards. Off-site contractors must verify requirements before constructing the fire protection system. Piping specifications include Class 150 PSI, with PVC water main piping less than 4 inches in diameter needing to be Schedule 40 per ASTM SDR 21. Larger PVC water main piping, from 4 to 12 inches in diameter, must conform to AWWA C900 (DR 18) standard specifications. This item is currently under review. The work will involve underground utility installation, including trenching, pipe laying, and connection to existing systems, followed by testing and inspection. Contractors specializing in underground utilities, civil engineering, and material supply could find opportunities. Engaging early, before final plans and permits are set, allows businesses to understand project needs and prepare for potential work.
