Single family residential sewer customers of SouthWest Water Company’s (SWWC) Riverview sewer system receive an automatic 15% discount each month on the volumetric portion of their sewer bill. The volumetric portion is based on the volume of water purchased from the Birmingham Water Works Board (BWWB). In lieu of receiving the automatic discount, a customer may submit a request for a Voluntary Private Meter Adjustment. Upon validation of the existence of the installed private meter at the service address provided, SWWC will modify the customer’s account to remove the automatic discount and an adjustment/ credit will be applied based upon VALID private meter reading data provided by the customer. Private meter adjustments are allowed on an annual or semi-annual basis only. Submissions for a period greater than one year will be void, and any consideration for a credit will be limited to a calculation of 15% based upon the most recent 12 months of actual volumetric use as recorded by BWWB. It is the customer’s sole responsibility to submit the form with a 12 month period to receive an adjustment.
