About Your Domestic Bill

The Entitlement Charge is the cost for water consumed within your domestic bi-monthly shareholding entitlement.  The Supplemental Charge is the cost for water consumed over your 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.   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.  Bi-monthly entitlement tables are shown below for your reference in determining your entitlement throughout the year.  Please be advised that the entitlement is for the two months being billed and is not considered a roll-over. These amounts can change as water supply conditions indicate.
