Explaining your AWMC
April statements is the time Castle Rock Water adjusts the Average Winter Monthly Consumption (AWMC) for each individual customer. The AWMC is just what it sounds like - an average of your actual usage during the months of November through February. The AWMC determines two things on your monthly Castle Rock Water statement: the amount of water for indoor use (Tier 1) and the amount of wastewater treated each month. Though your water use may change slightly year over year, we readjust the AWMC each year since factors in your household may have changed. Because what comes in must go out, we also use this amount to calculate your wastewater charge. This charge is a fixed charge and remains the same each month throughout the year, until recalculated during the next capture period.
It is more economical to have a low AWMC so that this wastewater charge is low. Even if you happen to go over your tiered water budget occasionally, the accumulative charges will most likely be less than having a higher AWMC and monthly wastewater charge.
