. Prince George, B.C. required 15 mgd additional municipal water supply. A cost comparison led to the selection of the Nechako Aquifer ground‐water supply instead of the Nechako River surface‐water supply. A Fehlmann horizontal collector, consisting of a 16‐inch diameter reinforced concrete caisson, 100 feet deep, with 1788 feet of 8‐inch diameter polystyrene screen, projecting spoke‐like at the bottom of the caisson, was installed. On test, the collector produced 15.3 mgd of clean, excellent quality water, with 6.7 feet drawdown under equilibrium conditions.
