The Water Division is responsible for the operation, repair, and maintenance of all water lines, valves, and fire hydrants. The Water Division performs daily sampling required by the State of Texas to maintain a superior water quality rating for the citizens of Frisco. The City of Celina purchases treated water from the Upper Trinity Regional Water District. The water is stored in a ground storage tank until it is pumped to one of our elevated water towers. Water is then distributed through pipes to Celina citizens.
