It is the intention of the NKWD for all residents within its service area to have access to the public water system. In the last 10 years, the NKWD has added approximately 42 miles of new water mains. Currently 99 percent of Kenton County households are served by NKWD. The remaining one percent, approximately 452 households, requires 57 miles of lines to add these properties to the water system. This extension of the water system will cost an estimated $30 million. To add households to the water system, NKWD applies for grants to help cover the costs of laying new water lines. These grants are usually available only to low-income participants, however, limiting their use. All new lines are a minimum of eight inches in diameter to ensure enough water pressure for fire hydrants.
