San Angelo city council members took the first step in a long-range plan to update the citys water infrastructure this week. As we reported Tuesday, they gave preliminary approval to a significant water and sewer rate increase. City workers are in the middle of a major upgrade -- replacing water mains and pipeline in front of the old r-g barry factory on loop 306. Its part of a multi-year project to replace water lines on the southwest side of the city. Water utilities director Will Wilde says projects like this are the reason you could soon be paying at least 12 dollars and 70 cents more for city water and sewer service. City council members are expected to give final approval to the rate hike at their next meeting. The average 12 dollar and 70 cent increase could go into effect in july.
