Body
BACKGROUND: The Norman raw water line conveys water from Lake Thunderbird to the Water Treatment Plant (WTP). The raw water line begins at the lake as a 33-inch concrete line and extends west 5.7 miles where it reduces to a 30-inch concrete line. The 30-inch line continues west another 2.25 miles terminating at the WTP. These lines were originally constructed in the 1960’s when the Lake was being built.
On July 27, 2010, the Norman Utilities Authority (NUA) awarded the bid to Red Cliff, Inc. of El Paso, Texas and contracts were executed in the amount of $3,171,711 to lay a new parallel 48-inch line along the last 2.5 miles of 30-inch. The purpose of the larger line was to allow a greater quantify of water to be drawn from the lake over a defined period of time. Although the pipes connecting to the lake are smaller than the new 48-inch line that would be connecting to the WTP, the larger line significantly reduces friction loss that would be present in a smaller pipe, thereby allowing a greater quantify of water to flow over the same defined period. The goal was to allow the City to draw up to 17 million gallons per day (mgd) as opposed the current 14 mgd. This additional drawing capacity was felt to be very important to allow the NUA to draw sufficient water resources from its primary water supply, Lake Thunderbird, during peak demand periods, and as we continue in the current drought.
Construction began on September 27, 2010 and was scheduled to be complete by March 26, 2011. The project was not completed as originally scheduled. The water line has now been laid, although not connected at 60th Ave NE or at the WTP. A change...
