PERFORMANCE UPDATE OF SUBCONTRACT
The City of Columbus is finishing a $5-M rehabilitation project to convert "single-sand" filters to high-rate "dual-media" filtration.
UNIFILT has completed its subcontract with Kokosing Construction Company of Columbus at the Hap Cremean Water Plant (Morse Road). As specified by Malcolm Pirnie, Inc., Columbus, the project encompasses: furnishing the necessary equipment and labor required to remove the old support gravel and sand material, supplying new dual-media and hydraulically installing the high-rate dual-media system in Plant B. Each of the 12 Double-bay Filters is 15'4" x 46' and has a total filter area of 16,927.92 square feet.
Filter capacity is being increased from 72 mgd to 96 mgd for this filter building. One filter at a time was renovated to maintain plant flows and to facilitate construction.
After several renovated filters were placed in service, increasing filter capacity, more filters were then removed from service.
HISTORY OF WATER DISTRICT
The idea of a storage reservoir and water plant on Big Walnut Creek was first proposed in the early 1940s. When the Second World War began, all planning was suspended. After the war, engineering was completed and land acquisition had begun. Construction started on the dam in 1953, and at the plant site in 1954. By late summer 1955, the $7.3-M Hoover Dam and Reservoir project was completed.
Meanwhile, work was progressing on the water plant. On June 15, 1956, the $6.3-M Morse Road Water Plant was placed in operation, using water released from Hoover Reservoir.
The plant was able to process an average of 60 mgd and to operate at 72 mgd. In 1967, contracts were awarded for an expansion program - doubling the size of the original plant. This was completed in June 1971 at a cost of $12.6-M. This new expanded facility, actually two separate plants side by side, today processes an average of 130 mgd.
The Hap Cremean Water Plant is the oldest of three water plants in the City of Columbus and has been on-line since 1956. This plant supplies approximately 60 percent of the water needs for the greater Columbus area.
