Park Service officials said the work should not cause any restrictions or closures this year that would impact visitors.
The project is expected to be completed in 2027.
Originally built in the 1960s, the 12 ½-mile waterline provides the potable water for all facilities on the South Rim and inner canyon facilities within the park.
Park Service officials said that since 2010, there have been more than 85 major breaks in the waterline with each repair often costing more than $25,000.
