The average homeowner in the city of San Antonio is expected to pay an additional $4.93 on their monthly water bills if the city approves the new net rate increase.
San Antonio Water System announced a net rate increase of 9.9 percent is needed for water bills in 2013 to meet the basic needs of its sewer system.
SAWS said the net rate is also necessary to reduce sanitary sewer overflows and bring new water supplies to the city.
Even with this increase, SAWS said the city's rates would remain among the lowest in Texas.
Since the announcement of the new rate, the department has provided a website that allows residents to calculate how much their bills will increase.
