(a) No person shall open, carry from or tamper in any manner with a fire hydrant connected to water board mains, unless a written permit is obtained from the director. However, this does not apply to employees of the city's fire department engaged in the pursuit of regular duties.

(b) The director shall be notified within 24 hours of the use of any hydrant by the city fire department.

(c) Wrenches, other than hydrant wrenches acceptable to the director, must not be used for the operation of fire hydrants. The use of any other type of wrench shall be considered sufficient cause for cancellation of any permit issued and for the imposition of a fine equal to the real cost to cover repairs or replacement.

(d) The general use of hydrants for construction purposes will be restricted when a service line to a building or structure will eventually be required. All hydrant use other than fire fighting purposes requires a valid hydrant permit and the use of a water board certified meter-backflow hydrant assembly. When a hydrant is being used under permit, regular reducing couplings attached to the nozzle of the hydrant and equipped with an independent valve for regulating flow shall be used. The main valve of such hydrant must be opened fully at the beginning of each workday and remain open until the finish of work on that day, when it shall be completely closed.

(e) A hydrant flow test service charge as identified in the board schedule of rates, payable in advance to the water board, shall be assessed for hydrant flow tests performed by the water board.

(f) In obtaining water from a fire hydrant in conformity with the foregoing subdivisions, no leakage will be tolerated. The hydrant permit shall be rescinded for any violation and appropriate fees for damage will be assessed.

(g) No person shall obstruct access to any fire hydrant in any manner whatsoever, without the written approval of the director.
