Reconstruction of Booster Pump Station 106 is complete! Join us for our Open House event on Monday, October 6, 2014 from 5:00 to 7:00 pm at the new booster pumping station in Reservoir Park.  The facility is located at 110 Glenway St, between Zwerg Dr and Ridge Rd.

You can find information on the history of Booster Pumping Station 106, including original film footage of its 1925-26 construction, on our Inside MWU page.


Booster Pumping Station 106 (BPS-106) is an interzone transfer pumping station located on Madison’s near-west side in the sloped embankment of Reservoir Park.  The primary function of BPS-106 is to transfer water from Madison’s main pressure zone (PZ 6, central Madison) into the City’s southwest pressure zone (PZ 7, west side, southwest side).  The pumping station draws water from the adjacent 6,000,000 gallon buried reservoir (hence, Reservoir Park), which stores water from wells in PZ 6, and then BPS-106 pumps the water into the higher-pressure PZ-7 areas.  This pumping facility has been operating since 1926 - making it Madison Water Utility’s oldest operating facility.

The reconstruction of BPS-106 is one of Madison Water Utility’s high-priority infrastructure replacement projects (see the Madison Water Utility Infrastructure Management Plan). The replacement of BPS-106 is part of the Water Utility’s 2012-2014 Capital Improvement budget.  The BPS-106 reconstruction project addresses both condition/deterioration problems and will increase the reliability of this critical system facility. 

The scope of the replacement project is as follows:

  • The existing facility contains one single-speed pump with a capacity of 1,500 gallons-per-minute (gpm).  The new facility will provide additional capacity and better system redundancy with two variable-speed 2,100 gpm pumps.  Additionally, the new pumps will incorporate remotely controlled pressure-reducing valves which will allow the pumps to operate in reverse (from PZ-7 into PZ-6), as needed.  As possible, space will be provided to allow future accommodations such as electrical equipment expansions or chlorination equipment.
  • A tank mixing system will be added to the buried reservoir.  The addition of a tank mixing system improves water quality & consistency by eliminating “dead spots” (areas of water not regularly drawn into the existing system) which may contain chlorine levels that are too low or non-existent compared to other areas in the reservoir. 
  • The deteriorated access/vent structures located on top of the buried reservoir will be replaced.
  • The rainwater drainage on the top of the buried reservoir will be improved to eliminate the occurrence standing water.


On August 7, 2012, the City of Madison Common Council authorized the City/Madison Water Utility to execute a Professional Services agreement with Strand Associates, Inc. to provide engineering and design services for the reconstruction of BPS-106.


The final design of this project was completed with valuable input from a Citizens Advisory Panel (CAP). Madison Water Utility's CAPs are project-specific, usually made up of people to live or work where a project is happening. Although the work of this CAP is finished, there are plenty of new projects on the horizon. If you'd like to get involved, check out our Project News Page, or contact Madison Water Utility at (608) 266-4651 or


What is the project’s anticipated schedule?

  • The design of the reconstruction project will begin in fall 2012 and should be completed, reviewed, and ready to bid in March or April of 2013.  The bidding/preconstruction phase will likely extend to June or July of 2013.  Construction of the replacement facility is anticipated to occur from summer of 2013 to spring of 2014.


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

  • You shouldn’t experience any interruptions in water service due to this project.  If a service interruption would need to occur, you would receive at least 48-hours notice prior to the planned interruption. 
  • If you do experience a service outage and were not notified in advance by the Water Utility, please call the 24-hr operator at 608-266-4665.


How will my drinking water be affected by this project?

  • BPS-106 transfers water pumped by PZ-6 wells (mainly Unit Well 14, Unit Well 6, Unit Well 27 & Unit Well 19) from the Glenway reservoir into PZ-7.  The areas of PZ-7 receiving this water also receive water from Unit Well 12 located within PZ-7.  With the increased pumping capacity of the new BPS 106, it is likely that customers in PZ-7 will receive a higher percentage of water from the PZ-6 wells compared to right now.    
  • See which wells are serving your address.
  • See water quality reports for Madison Municipal Wells.
  • For any questions related to water quality, please contact the Utility at 266-4654 or


How will the project affect Reservoir Park and/or traffic on Glenway St?

  • It is likely that traffic on Glenway St in front of the project area (north of Zwerg Dr and south of Ridge Rd) will be closed for material/equipment staging for most, if not all of the project’s construction.
  • It is likely that some trees/brush on the sloped embankment located above or near the booster station on the Glenway St side of the reservoir will need to be removed during construction.  Madison Water Utility, City of Madison Parks Dept., and City of Madison Forestry Dept. will be evaluating the impacts to trees as the potential designs of the replacement facility are developed.
  • A playground improvement project at Reservoir Park is being proposed as an amendment to the 2013 City of Madison Capital Budget.  With its approval, Madison Water Utility will be contributing funds to the Parks Dept. in support of the playground improvements.


How much do you anticipate the reconstruction project will cost?

  • The construction contract is valued at $2.317 million.  Staab Construction Corporation is the General Contractor for the project.




  • On April 17, 2013, the Board of Public Works met to review the proposed project for bidding at the City County Building.


  • An information-only meeting of the Board of Parks Commissioners with an Overview of Proposed Project was held April 10, 2013 at the Goodman Maintenance Facility.


  • A meeting regarding the Parks Dept. Reservoir Park 2013 Playground Improvement Project was held April 9, 2013 at the Midvale Elementary School cafeteria.


  • An Urban Design Commission meeting to review proposed facility plan was held April 3, 2013 at the Madison Municipal Building.



  • A Public Hearing before the Water Utility Board was held January 29, 2013 at the Water Utility Conference Room, 119 East Olin Ave.
