It is important that the map we have on file for your service area is accurate. The population data and ratios provided in Section B are based on this map. If your service area has expanded significantly (e.g., recent annexation) or shrunk (e.g., deletion of territory), you should contact us. Contact information is found in the lower right corner of this website.
Please note that we are unable to make changes to your utility retail water service area boundary if they would result in overlaps with another utility. Any population within, or projected to be within, an overlap will be counted as self supplied (i.e., not included in either service area) for all District applications of this GIS layer. To incorporate your new boundaries into our GIS layer requires supporting documentation that would substantiate any claimed overlapping areas. By rule, revisions to your service area boundary must be made relative to the boundaries in the District’s service area layer to avoid unintentional overlaps. Please review contact information associated with your service area. You may submit updates using the Public Supply Service Area Information form. Keeping this information current ensures you are notified of any apparent discrepancies, overlaps, or other service area related issues.
By rule, significant definable areas (such as blocks, subdivisions and trailer or RV parks) that are self-supplied within your service area must be delineated and identified as “self-supplied.” Other utilities within your service area must be excluded or they will result in an overlap.
