18-29-603.3.2 Connection to metered service.
   Where this chapter requires the water supply for any building, structure, premises, or any part thereof to be under meter control, it shall be unlawful for any person to connect any building, structure, or premises, or any part thereof or addition thereto, with any service or supply pipe other than a service or supply controlled by a water meter. Such water meter shall be installed at the time of connection to the city's water system.
(Amend Coun. J. 7-29-15, p. 3537, § 4)
18-29-603.3.3 Licensed and bonded contractor.
   Where this chapter or the rules or regulations of the Commissioner of Water Management provide for the installation of a water meter on any service pipe supplying water from the Chicago Waterworks System to any building, structure, or premises, such meter shall be installed by a licensed and bonded plumbing contractor.
(Amend Coun. J. 10-14-21, p. 37722, Art. VI, § 4)
18-29-603.3.4 Location.
   The location of such meter, either inside or outside of any building or structure, shall be determined in writing by the Commissioner of Water Management in accordance with this section. The installation of any water meter at any location other than that permitted by said Commissioner is prohibited. Installation of any water meter shall be in accordance with the following:
   1.   No meter may be installed within a dwelling unit in a building containing more than three dwelling units or where the meter serves more than three dwelling units.
   2.   For services 1 inch (25 mm), 1 1/2 inches (40 mm) or 2 inches (50 mm) diameter: Meters shall be installed within 2 feet (610 mm) of the front wall of the building. The maximum distance a meter may be installed from the property line to meter is 50 feet (15.25 m). Any installation of a service 1 inch (25 mm), 1 1/2 inches (40 mm) and 2 inches (50 mm) over 50 feet (15.25 m) will require the installation of a meter vault in the public way.
   3.   For services 3 inches (75 mm) diameter and above: Meters shall be installed within 4 feet (1220 mm) of the front wall of the building. The maximum distance the meters may be installed from property line is 100 feet (30.5 m). A meter vault is required in the public way in any circumstance in which the distance from the property line to the meters exceeds 100 feet (30.5 m). Any installation in excess of 100 feet (30.5 m) will require the installation of a meter vault in the public way.
   4.   All new combination (fire and domestic) service shall require a domestic meter and an approved backflow device with bypass meter for the fire system. If these services are in excess of the 50' for 2 inches (15.25 m:50 mm) or 100' for 3 inches (30.5 m:75 mm) they must meet the above requirement and shall require the backflow preventer to be installed in an above ground-heated enclosure "hot box," located as close to the property line as physically possible.
   5.   Service used in conjunction with trunk lines (private water mains) requiring private fire hydrants shall have compound meters installed in a meter vault in the public way. Private hydrants are to be painted federal safety green.
\(Amend Coun. J. 11-8-12, p. 38872, § 344; Amend Coun. J. 10-14-21, p. 37722, Art. VI, § 4)
18-29-603.3.5 Construction of meter vaults.
   Wherever a water meter is installed in the ground, either inside or outside of any building or structure on public or privately owned property, it shall be enclosed in a meter vault. Such vault shall be built of hard pressed common brick or portland cement concrete blocks laid up in portland cement mortar, poured portland cement concrete, extra heavy, salt-glazed vitrified clay tile pipe, portland cement concrete pipe, or equally durable material. This meter vault shall be provided with a removable cover. Each meter vault shall be built to conform to the specifications and dimensions for meter vaults issued by the Commissioner of Water Management.
(Amend Coun. J. 11-8-12, p. 38872, § 345; Amend Coun. J. 10-14-21, p. 37722, Art. VI, § 4; Amend Coun. J. 12-14-22, p. 58278, Art. VI, § 7; Amend Coun. J. 4-19-23, p. 62477, § 1)
18-29-603.3.6 Installation of taps.
   No water main shall be tapped other than by a tapper employed by the Department of Water Management or a contractor hired by the Department of Water Management for lead service line replacement, and all tapping shall be performed only under the authority of the Commissioner of Water Management. All service cocks or ferrules must be inserted at or near the top of the street main, and not nearer than 6 inches (150 mm) from the bell of the pipe. The size of the cock shall be that specified in the permit. Each service pipe shall have its own independent tap at the main and said tap shall be of the type in use by the Department of Water Management.
(Amend Coun. J. 11-8-12, p. 38872, § 346; Amend Coun. J. 10-14-21, p. 37722, Art. VI, § 4; Amend Coun. J. 12-16-24, p. 22879, Art. I, § 7)
18-29-603.3.7 Plans accompany permit application.
   No permit for the installation of any pipe or system of piping taking water from the Chicago Waterworks System for distribution in any building or structure shall be granted until a plan of such water supply or distribution system has been examined and approved by the Commissioner of Buildings or Commissioner of Water Management. Such plan or plans shall be presented with the application for permit and shall clearly show the complete water supply piping system from the service to the plumbing fixtures and other appliances including fire protection equipment, to which such water supply piping system is connected, together with detail drawings of connections to surge tanks, storage tanks, pressure tanks, filters, swimming pools, bathing and display pools, hydrotherapy pools, sterilizers, condensers, compressors, reservoirs, and washers.
   For private water systems within the City of Chicago the owner, agent, contractor or permittee shall provide to the Commissioner of Water Management an as-built drawing within 30 days of completion of the private water system. The as-built drawing shall identify the location and size for every main, control valve, meter vault, fire hydrant, line valve, service valve, meter and individual service location connected to the Chicago Water Works System.
(Amend Coun. J. 11-8-12, p. 38872, § 347; Amend Coun. J. 10-14-21, p. 37722, Art. VI, § 4)
18-29-603.3.8 Notification of wrecking buildings for terminating water service.
   No building, structure, or premises shall be permanently abandoned, wrecked, or destroyed without the previous notification, in writing, to the Commissioner of Water Management of such abandonment, wrecking or destroying, in order that the water service may be shut off, and leaking or wasting water shall be eliminated or prevented; and accompanying said notification, ample financial provisions, such as the deposit of the estimated costs of disconnection and sealing of water service pipes or posting of a surety bond, shall be made to the satisfaction of the Commissioner of Water Management to ensure the payment of all costs and charges for the shutting off of said water service. Such notification and assurance of payment shall be given by the person in charge of the wrecking or destroying of the building or by the owner of the building, structure, or premises.
   No person, other than employees, agents or contractors of the Department of Water Management, shall be allowed to operate any line valve in any water main. Such employees, agents and contractors shall follow the Department's written policy for service terminations. If the termination is not performed pursuant to the Department's written policy, in addition to other applicable remedies, the Commissioner of Water Management may repair the defective termination at the owner's expense, require the owner to repair the defective termination, or terminate any new water service to the building at the owner's expense.
(Amend Coun. J. 11-8-12, p. 38872, § 348; Amend Coun. J. 7-29-15, p. 3537, § 4; Amend Coun. J. 10-14-21, p. 37722, Art. VI, § 4)
