About Your Municipal/Miscellaneous Bill

The Entitlement Charge - is the cost for water consumed within your monthly shareholding entitlement. 

The Supplemental Charge (Tier 2) - is the cost for water consumed over your entitlement up to your entitlement allowance. 

The Tier 3 Charge is all usage over 200% of entitlement.

The Readiness to Serve Charge - is based on your meter size and is a portion of the costs to keep the system ready to provide your water demand. 

The Water Availability Charge (WAC) - is based on the amount of shares owned at $8.00 a month per share. Your shareholding entitlement (as shown on the bill) is proportional to the total number of shares outstanding and the amount of water that is available for distribution.  Monthly entitlement tables are shown below for your reference in determining your entitlement throughout the year.  These amounts can change as water supply conditions indicate.
