Utility Capital Projects

Project Name Project Description
Big Fossil 24" Interceptor - This project is for the replacement of the 24 inch wastewater main running from the Fort Worth meter station to just
Continuing Project south of Holland Dr. This project will include replacement of roughly 2400 linear feet of reinforced concrete pipe,
replacement of seven manholes, and will require bypass pumping during construction.

Assess and Repair 16-inch This project will consist of assessing the 16-inch concrete bar-wrap pipe (BWP) water transmission main that begins at
Water Transmission Main - the Airport Freeway entry point and extends to the Conn Ground Storage Tank. This transmission main transports water
Continuing Project from the City of Fort Worth to the City of North Richland Hills. The total length of pipe to be inspected is approximately
8,300 linear feet. There are 7 different phases to the assessment: site reconnaissance and project planning, transient
pressure monitoring, leak and air pocket detection, electromagnetic (EM) inspection, pipe performance curve, final
report, and field verification/validation. These seven phases will identify the pipes that need to be reconstructed or
rehabilitated. Once the assessment has been completed, staff will begin planning the identified necessary repairs and or
section replacements. Staff has already identified a section of pipe, roughly 300 feet, along Airport Frwy that will be
repaired as part of this project. An entry point and exit point will be constructed to gain access for the assessment.

Automatic Control Valve (ACV) This project will replace the six automatic control valves (ACV) at Watauga Pump Station. These six valves include: 3 -
Replacement - New Project 10 inch valves and 3 - 6 inch valves. The ACV's are a vital component in the process of providing adequate pressure
and quantity in the water distribution system that serves both the City of North Richland Hills and the City of Watauga.
The ACV's main purposes are: eliminating pressure spikes, back siphonage, and controlling the flow of water from the
pump. The valves are located on the effluent side of the six pumps before the discharge header.

Big Fossil Creek Wastewater This project consists of constructing a parallel wastewater outfall main from the North Richland Hills metering station,
Outfall - Continuing Project which is north of State Highway 10 to the Trinity River. North Richland Hills, Richland Hills, Haltom City, and Fort Worth
discharge sanitary sewer into this section of the existing outfall mains. Each city will pay a portion of the cost based on
volume of flow from their city. The size of the main will vary, but will be as large as 90" in diameter. North Richland Hills
will need to pay for connecting its existing outfall to the new outfall. After the new outfall is complete, both wastewater
pipelines will be owned, operated and maintained by Fort Worth as part of its system.

College Hill Ground Storage This project will consist of constructing two water pipes so the storage tank will fill from the top. The pipe being added
Tank Stand Pipe - Continuing is called a stand pipe. This will allow new water to be added to the tank in order to mix with the older water in the tank.
Project

College Hills Ground Storage This project will rehabilitate the College Hills Ground Storage Tank. This will include preparing the exterior and interior of
Tank Rehabilitation - New Project the tank to apply new paint on both surfaces. Additional work will include: installing pipe screen at overflow, installing a
ladder gate, installing a new hatch on the roof, installing a new vent, repairing the float system, caulk and seal at the
foundation, install a new safety climb system, and remove the existing interior ladder.
