A water-improvement project to meet municipal code requirements in Murray, Holladay and unincorporated Salt Lake County gets under way this summer.

The Big Cottonwood Tanner Fire Flow Improvement Project will consist of replacing existing small-diameter water mains with larger water mains. In addition, substandard fire hydrants throughout the project area that are connected to Salt Lake City water mains will be replaced, and new fire hydrants will be added to meet the current spacing required by local codes.

Salt Lake City also will take advantage of the opportunity to replace any water services constructed of galvanized steel with new copper piping to the meter box. In all, more than 37,000 feet of 8- and 12-inch piping and 180 fire hydrants will be installed during this project.

There will be no expense to water users in the project area for the improvements. The project is the result of a cooperative agreement between Salt Lake City and the Big Cottonwood/Tanner Irrigation Co.

A public open house about the project is scheduled from 6 p.m. to 8 p.m. July 2 in the Big Cottonwood room of Holladay City Hall, 4580 S. Holladay Blvd. Salt Lake City officials and the project's contractor and engineer will be on hand to explain the project and answer specific questions from residents.

Areas that will be impacted by the project are generally located between 1300 East and Holladay Boulevard, and between 5600 South and 6400 South, with some additional work taking place at a few locations on 900 East, 1300 East, Vine Street and 4800 South (Murray Holladay Road).

Work on the project is anticipated to begin in July and will continue through early fall of 2009. As a majority of the work will take place within existing streets, short-term road closures and detours may be required. Fliers will be distributed to residents of areas adjacent to the work before construction activities begin. The fliers will indicate the timing of construction, anticipated closures anticipated water service outages and other impacts of the project.

In order to expedite the work, minimize the impact on the neighborhoods and protect personal property, it is requested that residents avoid parking vehicles, trailers, boats or recreational vehicles within the public right of way while construction activities are taking place on their street.

The project is expected to have little impact on daily water uses, though some areas may experience small changes in water pressure. Once the project is complete, officials say, residents of the project area will benefit from a water system capable of delivering the water flows required by the local fire department to protect the property within the area.
