Residents of west Farmington will pay $1,050 to hook up to the city's water system when it is eventually extended into the area under a development plan approved Wednesday by the Farmington City Council.

Estimating construction costs of a west Farmington culinary water system at nearly $2 million, the council voted to impose a surcharge of $350 per residence for hookups in addition to the city's current $700 water hookup impact fee.Only a small part of the west Farmington area west of I-15 is currently annexed into the city, mostly surrounding the 100-acre site of the county's new municipal justice complex and fairgrounds south of Clark Lane.

There is no culinary water system in the area now, but construction of the jail will precipitate water, sewer and other utility services, and the council is preparing a master plan for installation and financing.

In a public hearing Wednesday before passage of the fee schedule, several west Farmington area residents asked questions about the proposal but appeared to mostly favor it.

City Manager Max Forbush said the city's philosophy is for developers and property owners to pay for the system as they annex over the next several years into the city.

An engineering study done in 1981 estimates installation of a water system, including trunk lines and two storage tanks in the area, at just under $2 million. The study estimates the 2,800 acres in the area will eventually have 5,600 residential connections, putting the fee at $350 per house.

The sliding fee schedule starts at $350 for a 3/4-inch connection, standard for homes, and imposes higher fees for larger connections for businesses and commercial use, up to $25,250 for a 4-inch commercial hookup.

Forbush said the county is anticipating two hookups to serve the jail and court complex, totaling $16,500 in fees.

Farmington currently has enough water reserves to provide service for part of the area, Forbush said, but anticipates having to eventually drill another well to provide service for all of it.

A 10-inch water main under the State Street overpass under I-15 ends just west of the freeway, Forbush said, but will be extended to serve the jail. The city installed a 15-inch casing under I-15 near the Oakridge County Club but no pipe is in it yet and a third line following Glover Lane over the freeway will also have to be installed.

City councilman Art Maxwell, the former city engineer, did the study in 1981 and updated for the current fee schedule.
