County engineers describe water-modeling for data centers; developers must model demand and pay for needed upgrades
Sep 11, 2026
Deputy engineer Kerry Williams explained the county's calibrated hydraulic models for the Scott Candler water system, the 40‑PSI fire‑flow standard used for approvals, and how developers (including data centers) must model demands and pay for new infrastructure or cost-share upsizes.
The full story
Kerry Williams, deputy of engineering, summarized how the county models water distribution and verifies that the system can maintain pressures and fire flow when large users apply to connect. He said the model includes the Scott Candler Water Treatment Plant, roughly 3,000 miles of distribution mains, storage tanks and pump stations, and that project reviewers can insert a developer's projected demand to see localized impacts.
