Constructed in 1872 as part of the water supply system for the City of Newport, KY, the Ohio River Pump Station No. 2 (ORPS2) is now an integral component for the Northern Kentucky Water District (NKWD) and the 300,000 customers they serve. After an inspection, it was determined the main operating floor was becoming structurally unsound, and other critical elements of the facility were in need of repair. NKWD is upgrading the facility to help maintain the reliable delivery of raw water from the Ohio River to their water treatment plant.

Structural rehabilitation design efforts were focused on replacing the main pump room floor and repairing the limestone block foundation. In addition, the coarse bar screen, influent sluice gate and other facility components were beyond their useful service life, and needed to be upgraded or replaced.

Alternative replacement materials were presented for the trash rack, which had become encrusted with zebra mussels. This is an issue for many surface water supplies. A copper alloy was chosen due to the retrofit conditions, but also as a material NKWD can evaluate to determine whether it is effective at mitigating zebra mussel fouling.

The location of the pump station within the Ohio River was a unique construction constraint. Three sides of the building contact water, making the logistics of removing construction debris and delivering new materials, a challenge. Replacement of the coarse bar screen, influent sluice gate and inlet suction valve was below the river’s normal water level, requiring divers to perform some work. Foundation repair activities performed by the contractor were staged from watercraft anchored next to the structure, necessitating OSHA requirements for working over water and avoidance of river navigation impacts.

Because ORPS2 is a critical facility, the construction schedule needed to coordinate with the pump operation schedule. The project required coordination with the US Army Corps of Engineers, Kentucky Heritage Council, City of Fort Thomas and Kentucky Division of Water. Construction is scheduled for completion in February 2018.

Maintaining a Water Master Plan and designing distribution system improvements are ongoing components of our continuing engineering services to the City of Taylor, MI, a longtime client. Priorities include rehabilitating and replacing aging water main, upsizing smaller water mains to improve flows and pressure, and updating the water system computer model to evaluate future needs.

Current work is focusing primarily on the northwest section of the City, where more than 30,000 linear feet of water main rehabilitation and replacement was designed to improve water quality, increase the life of the system and reduce future maintenance costs. Water main is also being rehabilitated along a street in the City’s southeast quadrant with frequent water main breaks and across Eureka Road to assist in attracting new commercial development.

Construction is scheduled to be complete this fall using trenchless methods such as pipe-bursting and directional drilling to minimize water disruption for residents. Open trench construction is also being used to work around large utilities, including a natural gas line and fiber optic power feeder lines, along major roadways. Wade Trim is providing construction inspection services for this project.

The City of Southfield, MI, is investing in infrastructure renewal as a key factor to achieving long-term sustainability as an independent and thriving municipality. Boosted by the passage of a $99 million Street Improvements Bond in 2014, the City launched an aggressive capital improvements program and has been a leader in active road construction projects in Oakland County over the past two years. Most projects include water main replacement as part of the City’s ongoing efforts to reduce water loss and advance its continuing capital improvement initiatives.

Wade Trim provided design and construction inspection for road and water main replacement through a neighborhood in the south-central part of the City. The $5.19 million project consists of 17,578 linear feet of water main replacement using open cut construction, and more than three miles of paving, which includes asphalt replacement and, in certain areas, new curb installation. Divided into two construction phases, the project met substantial completion in June 2017. It is expected to be fully complete in September 2017.

Optimal timing of infrastructure improvements can have a big impact on the bottom line. When Wayne County announced plans to restore Mill Street near downtown Plymouth, MI, the City of Plymouth fast tracked a water main replacement project directly under the existing road to avoid higher road restoration costs later. Designed to limit impacts on this heavily populated area, the project replaced more than 1.5 miles of aged water main with PVC pipe using the pipe bursting construction method. Challenges consisted of siting bore pits and working within congested utilities and an extremely thick roadway cross section. Numerous sanitary sewer leads located above the water main were also replaced.

Wade Trim provided utility design and supported coordination and communication between the City, County and residents. In addition, the Plymouth-Canton Community Schools bus yard is located on Mill Street requiring coordination with the school district as well as construction phase planning to minimize impact on the schools. Wayne County’s mill and paving work on Mill Street from Ann Arbor Road to Main Street will complete this collaborative road restoration project by late September.

Aging water main originally installed in rear-lot easements of residential properties in the City of Venice, FL, is difficult to access for repair and replacement due to fences and vegetation. To improve future access and upgrade infrastructure, the City is undertaking a water main relocation program that will construct water main in the right-of-way in front of homes, reconnect water services to the new water main, relocate water meters to the new connection point, and then abandon the rear-lot water main.

Wade Trim developed a phasing program to define geographical boundaries and sequencing that divided the effort into seven project phases. GIS information was obtained from the City and field-verified to create a map of the water meters that need to be relocated. Phase boundaries were intended to divide the area into equal-sized projects that fell into the City’s annual budget for the program.

Wade Trim is also providing design, permitting and construction administration services for two phases of the relocation program, including coordination with property owners. The projects will relocate 293 water services, install 8,300 lineal feet of new PVC water main, and abandon more than 5 miles of aged water main. Due to the historic, residential nature of the project areas, much of the new water main is being installed via horizontal directional drilling, taking care to minimize impact to residents’ driveways and landscape. Water service is maintained from the existing rear-lot easement water main until the new right-of-way water main is installed, tested and cleared for use. Construction is anticipated to be complete in September 2016.

Brownstown Township’s three-year water main improvement program was honored as a 2013 Project of the Year (Environment $5 to $25 Million) by the Michigan Chapter of the American Public Works Association at their annual conference in Bellaire. With more than 16 miles of new water main delivered through pre-chlorinated pipebursting, the award recognizes the Township’s ability to improve water service for more than 1,000 residents and businesses while minimizing disruption and restoration costs. Wade Trim provided design, plan development and construction management for this program.

Water main replacement and rehabilitation were used to address areas in the distribution system that had experienced frequent breaks and other issues. Though a variety of construction methods were used, pre-chlorinated pipe bursting was used to install the majority of High Density Polyethylene (HDPE) pipe with fused joints and mechanical fittings. The technique was highly effective in residential areas with narrow right-of-ways and roads, canals and bridges. The existing 6- and 8-inch water main was rehabilitated by bursting a new 8-inch and 12-inch line and placing new gate valves and hydrants. The pre-chlorination process generally limited impacts on the residents to a one-day outage.
