Body
BACKGROUND: In 2001, the citizens of Norman approved a five dollar per month sewer maintenance fee providing for the systematic replacement of aged and deteriorating sewer collection lines.

The Phase 1 work consisted of 30,463 feet of sewer rehab and was complete in August 2017 at a cost of $2,124,371. Phase 1 was generally bounded by Robinson Street to the north, the Westwood Golf Course to the west, Denison Drive to the south, and Berry Road to the east.
