This project will replace 7,300 feet of 6-inch waterline with 8-inch waterline along Flood Street, generally between Robinson and Boyd Street. The 6″ water line is cast iron greater than 50 years old and has a number of leaks and repairs. Eleven waterlines crossing Flood will also be replaced with 8-inch by open trench construction . Costs have been increased to cover existing streets, parking lots and sidewalks to be removed and replaced.

In 2001, the citizen’s of Norman approved a Sewer Maintenance Fee of $5 per month per household to be deposited in the Sewer Maintence Fund 321. New projects are funded annually with funding utilized for design, inspection and construction activities which will repair or replace our aging sewer collection system including sewer lines and lift stations. Annual rehabilitation project, generally bounded by Boyd St. to the North, Wiley Road to the West, Lindsey Street to the South, and Imhoff Creek/Pickard Ave. to the east; additional lines may be added by staff if funding is available. Repair or replacement of about 19,200 feet of sewer is needed in the project area, subject to adjustments by staff due to unforeseen system operational considerations. Alternates may be bid, but are not identified yet.

This project assumes augmentation of Lake thunderbird with highly treated effluent (indirect reuse) is approved by ODEQ before 2025 and initial design begins in 2025. The project costs are taken from the 2060 Strategic Water Supply Plan, Portfolio 14 and generally consists of (1) a 3 MGD sidestream WRF treatment facility ($12.2M), (2) an effluent pump station and 3.9 miles of 30-inch force main conveying reclaimed water from the WRF to Dave Blue Creek ($21.9M), (3) 7 miles of 30-inch parallel pipeline from the Lake Thunderbird to the WTP ($44.9M), and (4) a 3 MGD expansion to the WTP ($8.8M). SWSP costs have been inflated forward at 3% per year to the expected start in 2025.

“Water Distribution Projects: The proposed water distribution system improvements are broken out by location and assume that funding will be pro-rated between development related and maintenance related needs. Line replacements are generally required due to age, material type and the current state of deterioration. Existing users are expected to pay for maintenance related costs while increasing the size of a waterline is a development related cost to be paid by connection fees or impact fees. Costs are pro-rated by comparing the internal area of the existing pipe to the area of the enlarged pipe.

Franklin Road from Railroad to 12th NW then north to Indian Hills: Replace 10,700 LF 8” DIP with 12” PVC. Estimated cost of $1.9M is pro-rated 67% to existing customers ($1.3M) and 33% to new development ($0.6M). ”

This project will install approximately 6 miles of 24-inch treated waterline from OKC to allow purchase of an additional 6 MGD of treated water from OKC. Connection point would likely be in NE Norman, possibly 12th NE or 24th NE and could act a potential blending point for non-potable groundwater and treated water. Costs taken from Table 3.7 of 2060 Strategic Water Supply Plan. 31,680 LF 24-inch at $335 per LF plus $563K for flow metering vault (2012 costs). This project could be considered as an alternative to the proposed groundwater treatment plant
