It shall be the duty of the Water Utility to see that all open ditches for water mains, hydrants, and service laterals are properly guarded to prevent accident to any person or vehicle, and at night there shall be displayed proper signal lighting to insure the safety of the public.
Contractors must call Digger's Hotline and ensure a location is done to establish the existence and location of all water mains and service laterals as provided in Sec. 182.0175, Wis. Stats. Where water mains or service laterals have been removed, cut, or damaged during trench excavation, the contractors must, at their own expense, cause them to be replaced or repaired at once. Contractors must not shut off the water service laterals to any customer for a period exceeding six (6) hours.
(a) Protective Devices in General. The owner or occupant of every premise receiving water supply shall apply and maintain suitable means of protection of the premise supply, and all appliances, against damage arising in any manner from the use of the water supply, variation of water pressure, or any interruption of water supply. Particularly, such owner or occupant must protect water-cooled compressors for refrigeration systems by means of high and/or low pressure safety cutout devices. There shall be provided means for the prevention of the transmission of water ram or noise of operation of any valve or appliance through the piping of their own or adjacent premises.
(b) Relief Valves. On all "closed systems" (i.e., systems having a check valve, pressure regulator, or reducing valve, water filter or softener) an effective pressure relief valve shall be installed at or near the top of the hot water tank, or on the hot water distribution pipe connection to the tank. No stop valve shall be placed between the hot water tank and the relief valve or on the drain pipe. (See applicable plumbing codes).
(c) Air Chambers. An air chamber or approved shock absorber shall be installed at the terminus of each riser, fixture branch, or hydraulic elevator main for the prevention of undue water hammer. The air chamber shall be sized in conformance with applicable local plumbing codes. Where possible, the air chamber should be provided at its base with a valve for water drainage and replenishment of air.
Water mains will be extended for new customers on the following basis:
(a) Where the cost of the extension is to immediately be collected through assessment by the municipality against the abutting property, the procedure set forth under Sec. 66.0703, Wis. Stats. will apply, and no additional customer contribution to the Water Utility will be required.
(b) Where the municipality is unwilling or unable to make a special assessment, the extension will be made on a customer-financed basis as follows:
(1) The applicant(s) will advance as a contribution in aid of construction the total amount equivalent to that which would have been assessed for all property under Subsection (a).
(2) Part of the contribution required in Subsection (b)(l) will be refundable. When additional customers are connected to the extended main within ten (10) years of the date of completion, contributions in aid of construction will be collected equal to the amount which would have been assessed under Subsection (b)(l) for the abutting property being served. This amount will be refunded to the original contributor(s). In no case will the contributions received from additional customers exceed the proportionate amount which would have been required under Subsection (a) nor will it exceed the total assessable cost of the original extension.
(c) When a customer connects to a transmission main or connecting loop installed at Water Utility expense within ten (10) years of the date of completion, there will be a contribution required of an amount equivalent to that which would have been assessed under Subsection (a).
(a) Application for installation of water mains in regularly platted real estate development subdivisions shall be filed with the Water Utility.
(b) If the developer, or a contractor employed by the developer, is to install the water mains (with approval of the Water Utility), the developer shall be responsible for the total cost of construction.
(c) If the Water Utility or its contractor is to install the water mains, the developer shall be required to advance to the Water Utility, prior to the beginning of the construction, the total estimated cost of the extension. If the final costs exceed estimated costs, an additional billing will be made for the balance of the cost due. This balance is to be paid within thirty (30) days. If final costs are less than estimated, a refund of the overpayment will be made by the Water Utility.
