On 05/30/2023, the Board of Directors enacted a rate increase of 4% on the supplemental water charge.  This increase applies to the portion of the supplemental water charge that relates the cost of purchasing supplemental water and the operation of the system.  It is necessary to keep pace with inflation.  The charge on your bill will depend on whether you previously pre-paid the capital cost for the supplemental water project.  The adjusted charge is summarized below:

For those who pre-paid capital: Charge increases from $57.81 to $60.12 (increase of $2.31, or 4%)

For those who still pay capital: $90.02 to $92.33 (increase of $2.31, 4% only applied to operating/water cost)

This change was effective 11/1/2023.
