“…Provision was also made in the Water District Act that when any municipality used more than 200,000 gpd * of water it could request, and the district had to construct, a separate supply line from the aqueduct to the boundary of that municipality so that it could undertake its own pumping. The first use of this provision was in 1953 by St. Vital (3), although inquiries are made from time to time by other municipalities, several of which are considering the construction of their own pumping stations in the future.…”
