In April, the city of McKinney will begin a 10-year project to replace its water service lines.

Each year, the city takes account of its water quality, usage and water loss percentages. In May 2014, the city adopted a 12 percent water loss target as a part of the city’s Water Conversation Plan.

To meet this target, it is necessary to replace failing copper pipes contributing to water loss experienced by the city, officials said.

The project will replace nearly 14,500 copper service lines with more durable polyethylene pipe, also known as poly pipe. These service lines represent 54 percent of the city’s 27,000 service connections.

The premature failure of the copper service lines is mainly due to the deterioration of substandard copper material and aggressive soil in the region,  city officials said.
