Every even-numbered year, each District holds elections for Board of Director positions. Each District has a five member board that consists of property owners from within that District. The Castle Hills community is comprised of eight separate districts, Denton County Fresh Water Supply District 1-A though 1-H. If you have an interest in serving on the board of your District, please contact District 1-A staff for further assistance and filing information.


Each year the resident sewer bill is calculated utilizing a method called Winter Averaging. Sewer billing is based on the average amount of water used during the months from November through February. The four month average volume is the amount of sewer you are then billed from March to February of the following year. Only residents that have an active account, at the same address, are eligible for Winter Averaging. All other residents are charged a flat fee until Winter Averaging is achieved. If you see a change in the sewer portion of your bill this spring, it is due to your Winter Average changing from last year.
