Project Descriptions:

Unit Well 26 was constructed in 1988 and provides service to Madison’s Far West neighborhoods that are generally located west of Gammon Road and south of Mineral Point Road.  During winter months, when seasonal wells are shutdown, Well 26 also supplies water to most neighborhoods west of Rosa Road.

The facility consists of a deep well with a capacity of 2,200 gallons per minute, a 4 million gallon ground-level reservoir, and a 250,000 gallon elevated tank.  Groundwater is pumped from the deep well directly into the ground-level reservoir to serve Pressure Zone 8.  Two booster pumps transfer water from the ground-level reservoir to the elevated tank which feeds the higher-pressure Zone 10.  Over the last five years, average water supply pumped from Well 26 has exceeded 730 million gallons per year.

The primary project objective is to increase west side water supply reliability with an emergency back-up generator.  Back-up power for Well 26 has been identified as a high priority project.  In the event of a power outage at Well 26, water supply and fire protection on the west side would be adversely affected.  A back-up generator would allow MWU to continue to supply water normally for the extent of any power interruption.

MWU is also planning facility upgrades as part of the project.  These improvements will allow the Utility to replace aging electrical equipment, supply water at a steadier pressure and operate more energy efficiently.  The scope of the proposed construction project includes the following:

  • Addition of an emergency stand-by generator
  • Conversion of the booster pump motors from fixed-speed to variable-speed drives
  • Upgrade of the Motor Control Center
  • “Switch-Over” of the facility from the old to the new Motor Control Center
  • Landscaping and site restoration

On September 4, 2012 the City of Madison Common Council authorized the City/Madison Water Utility to execute a Professional Services Agreement with Baxter Woodman, Inc. for the preparation of drawings and specifications, permitting, bidding, and construction administration for the MWU’s upgrade of Unit Well 26.

Frequently Asked Questions:

What is the project’s anticipated schedule?

  • Project design will be completed and ready to bid in September of 2013.  The bidding/pre-construction phase will take place through October 2013.  Ground breaking is scheduled to occur in the spring of 2014 and construction will continue throughout 2014.  The project is scheduled to be completed in late 2014 or early 2015.

What is the project’s estimated cost?

  • The facility cost estimate is $500,000
  • The engineering cost estimate is $75,000

Will I experience water shut-offs or service interruptions due to this project?

  • The facility will remain in operation for the duration of the construction project with only short (4- to 6-hour) disruptions of service during the switch-over to the new equipment.  When service interruptions need to occur, affected customers will receive at least 48-hours notice prior to the planned interruption.

How often will the generator be run once it is installed; will it be noisy?

  • The generator will be run approximately once a month for 2-3 hours as part of its regular maintenance
  • City ordinance requires no more than 70 decibels at the property line.  This level is about that of a residential air conditioning unit.  With the generator inside a self-contained, silencing unit, we expect the noise level to be comfortably below the requirement.

How will the project change the look of the facility?

  • The generator will be located behind the water tower when viewed from High Point Road; the unit will be fenced and screened with landscaping
  • No trees or other existing landscaping are expected to be removed

How will the project affect traffic on High Point Road?

  • High Point Road will remain open in both directions although there will be occasional restrictions to one lane or very short duration closures to allow for the delivery of materials and equipment.
  • More than usual traffic in and out of the site for the duration of the project.
