For the third year in a row, Phoenix's average single-family residential water bill will remain at $37.75 per month, and the average single-family residential sewer bill will remain at $20.71 per month, both among the lowest in the nation.
In addition, the sewer bill is based on water usage. Hence, the incremental cost of 1,000 gallons of water and sewer use is $5.40 for water and $3.50 for sewer (2013 rates), for a total cost of $8.90. This total cost equals 9/10ths of 1 cent per gallon.
