Waterline Project
Background
In 2021, the Bipartisan Infrasture Law (BIL) was passed. It provides a 5-year opportunity of enhanced funding through the Safe Drinking Water Revolving Loan Fund (SDWRLF) to address various drinking water infrastructure needs.
Water Infrastructure improvements are included in the Priority 1 projects of our 2019 Master Plan. We had a Preliminary Engineering Report done in 2022. The report specifies various pipeline segments for replacement. Using the information in the PER, we applied for funding.
In Spring of 2023, we were invited to present our project to the Infrastructure Finance Authority (IFA). We are thrilled to announce our application was accepted!
Project Introduction
There are eight locations prioritized for upgrade. At these locations, the waterlines are inadequate, vulnerable to seismic events or made of hazardous materials and generally beyond their typical life cycle.
Replacing the waterlines would reduce the possibility of water service interruptions due to breaks in old lines and would also remove the danger that can come with maintaining and operating infrastructure constructed of hazardous materials.
Project Scope
Project includes, but is not limited to, final design and replacement of approximately 9,500 – 15,000 feet of waterlines located on 7-8 streets, as identified in the August 2022, Preliminary Engineering Report (PER) prepared by Civil West Engineering. Two Projects were not identified in the PER but were added to the project scope due to unexpected and dramatic pipe ruptures that occurred in August 2023.
- SW Seabrook Lane Waterline – 1,900-feet; PER Project #2: install a new 12-inch seismic resilient waterline and replace the old existing 8-inch AC pipeline. The new pipeline will be located along Seabrook Lane. Seabrook Lane is located near mile marker 3 along Hwy 101. The project will extend east along Seabrook for over 1,863 feet.
- SW Wakonda Beach Road Waterline – 2,000-feet PER Project #3: replace an old brittle smaller pipeline with a new seismic resilient larger pipeline to improve pressures and fire flow. The SW Wakonda Beach Waterline Project is located along SW Wakonda Beach Road. The project extends east along SW Wakonda Beach for approximately 1950 feet.
- SW Tara Lane to SW Forestry Lane – 2,500-feet PER Project #4: replace an old brittle smaller pipeline with a new seismic resilient larger pipeline to improve local and system wide pressures and fire flows. The existing waterline impacted by the new project extends from SW Tara Lane northeast along a private easement to a valve cluster on SW Forestry Lane, then north along the west border of the Forestry Department property, east along the unnamed road/driveway, and finally across Hwy. 101.
- East Side of HWY 101 from Fernwood Drive North to SW Whitecap Drive – many services line relocated and 1,000-feet of pipeline PER Project #9: discontinue the use of an existing 6-inch AC pipeline and reconnect all service lines and fire hydrants to an existing 10-inch PVC pipeline. The AC pipe is becoming costly to maintain. The project entails the disconnection of existing services from the old AC pipeline to the newer PVC pipeline. The project limits are along the east side of Hwy 101 between SW Whitecap Drive on the north and SW Fernwood Drive on the south.
- NE Camp One Street Waterline – 1,200-feet PER Project #10: replace an old, leaking, brittle existing 4” AC pipeline with a larger seismic resilient pipeline to provide fire protection and security. The waterline runs along NE Camp One Street. The project extends east from Highway 101 for 1,275 ft.
- NE California Street Waterline – 1,000-feet PER Project #11: replace a 4” brittle AC pipeline with a larger seismic resilient pipeline which will also provide for fire protection. The waterline runs 850’ along NE California Street. The project extends east from Highway 101.
- Dicks Fork transmission from Dick's fork WTP to Wakonda Beach Road – 4,000-feet – Not Included in the PER: replace the 8” PVC transmission line extending from Dick’s Fork Water Treatment Plant, and SW Wakonda Beach Road. The existing pipe does not meet existing construction standards (pipe is too thin, and radius of curvature is far beyond industry standards). In recent months the pipe has begun to fail in multiple locations. This project will replace 3,472 feet of transmission main. The waterline alignment is along a paved and gravel roadway within county road right of way.
- Wakonda Beach Road – 11,0000-feet - Not Included in the PER: replace the 8” PVC transmission line extending along Wakonda Beach Road from Highway 101 to SW Kathleen Street. The existing pipe does not meet existing construction standards (pipe is too thin, and radius of curvature is far beyond industry standards). Over the past few years, the pipe has begun to fail in multiple locations. This project will replace the 10,452 feet of transmission main. The waterline alignment is along a paved and gravel roadway within street right of way.
