VIII. FIRE HYDRANTS
A. Installation
1. The Authority will install and connect additional public fire hydrants to its existing water mains six-inch or larger in diameter whenever and wherever, in its opinion, such fire hydrants may be required to provide adequate fire protection service; or upon the written request and at the sole expense of any interested party.
2. The Authority will not be required to extend its mains for the purpose of supplying public fire hydrants which may be desired except under mutually acceptable arrangements to defray the installation cost of such extensions.
B. Maintenance
After the installation, inspection, and acceptance of a fire hydrant, the Authority will assume the ownership, maintenance and operation thereof, and will pay for any replacement or relocation which may become necessary.
C. Liability
The Authority shall not be considered in any manner to be an insurer of persons or property, or to have undertaken to extinguish fires, or to protect any persons or property against loss or damage by fire or otherwise, and shall not be responsible to any person or persons for any loss, damage or injury by reason of fire, water, failure to supply water or pressure, or any other cause whatsoever.
D. Non-Emergency Use of Fire Hydrants
It is the policy of the Authority to grant permits for the use of fire hydrants when no other water source is reasonably available and after payment of the applicable fees as specified in the Schedule of Rates under the following conditions:
1. Customers with recurring needs at various locations may obtain a fire hydrant use permit for an indefinite period.
2. Customers with a need at a specific location may obtain a fire hydrant use permit for a period not to exceed three years. The three year period may be extended by the General Manager when it is deemed to be in the best interest of the Authority.
E. Private Fire Service
1. Applicants for a private fire service or private fire hydrant will be required to submit a Site Plan for approval by the Authority. This Site Plan shall be approved by the Authority only after it has been approved by the Office of the Fire Marshal of Fairfax County.
2. The Authority may permit public fire hydrants to be installed on private property and, in such cases, the hydrants and associated easements required therefor, shall be conveyed to the Authority without cost and the Authority shall thereafter operate and maintain these hydrants.
3. Private fire Service Connections will be installed in accordance with regulations administered by the Office of the Fire Marshal of Fairfax County and must be inspected and approved by the Office of the Fire Marshal before service shall be commenced. The Authority will have the right to enter any property at any reasonable time for the purpose of inspecting fire service systems.
4. No water shall be taken or used through an unmetered fire Service Connection for any purpose other than for extinguishing fires or for the purpose of testing the fire service system. All tests must be conducted under the supervision of the Office of the Fire Marshal of Fairfax County.
5. The Authority shall not be in any way or under any circumstances held liable or responsible to any party for any losses or damage resulting from fire or water or other agency which may occur due to the installation or presence of a private fire Service Connection, or any pipe or fixture connected therewith; or for any losses or damage resulting from any leakage or other flow of water from said private fire Service Connection or any of the pipes or fixtures connected therewith; or for any losses or damage resulting from any excess or deficiency in pressure or supply of water due to any cause whatsoever.
