The District’s Rate Order states that bills for sewer service shall be computed (1) on the basis of the average amount of water used by the customer during the winter season based upon the average of the monthly readings of the customer’s water meter for the preceding December, January and February billing periods or (2) on the basis of the customer’s current monthly water bill, whichever is less.
If a residential customer does not have a history of water usage during the preceding December, January and February billing periods, the customer’s monthly sewer bill shall be calculated based upon (1) the customer’s current monthly water usage or (2) on the basis of 8,000 gallons water usage per month, whichever is less.
Winter months are used to calculate the sewer averaging because historically customers use less water this time of year.
If the averaging months are unusually warm, and the majority of residents use larger than normal amounts of water the Board may elect to drop the highest month’s usage.
Any resident filling a pool during the averaging months will be allowed to subtract the water used from the usage of the month the water was used. Requests for this must be made in writing to Andrew Hunt, c/o North Austin Municipal Utility District No. 1, 2601 Forest Creek Drive, Round Rock, TX 78665.
Any resident with a houseline leak during the averaging months may request a reduction in sewer usage. This also must be in writing and have documentation as to the leak and work accomplished to repair the problem.
Winter months are not the time to attempt to establish new lawns. Grass will not grow well and the water used will not automatically be deducted from the sewer average.
All requests for sewer average reductions will be reviewed before the March 2018 billing period.
