Madison Water Utility is building a new well facility and water reservoir at 4901 Tradewinds Parkway to bring better fire protection and more reliable service to the Southeast Side.  Construction of the $1.6 million ground storage reservoir was completed in May 2016. Currently, the well and filter building are under construction by Miron Construction Co, Inc. The water treatment plan is scheduled to be completed and in-service by July 2018. Construction cost: $5.9 million.

Latest News

Construction is complete and Well 31 is now in service! Thanks to everyone who provided feedback and support during this project. In September of 2018, water from Well 31 was named Best Tasting Water in Wisconsin by the Wisconsin Section of the American Water Works Association. Its water will be entered in the national taste test next year.

Project Background

On December 15, 2009, the Madison Water Utility Board voted to drill a new well at 4901 Tradewinds Pkwy to solve fire protection and supply redundancy problems in the area known as Pressure Zone 4, which serves areas in east and southeast Madison. Pressure Zone 4 is currently supplied by a single source, Unit Well 9, which makes the zone vulnerable to service interruptions. This Zone is also expanding rapidly to the southeast, away from Unit Well 9, making it difficult to move water efficiently and effectively to where it is needed.

You can find more pictures and background on the Well 31 project on our Inside MWU page.

Anticipated Project Schedule

Construction of Reservoir 31:  August 2015 to May 2016
Construction of well facility:  June 2017 to July 2018

Past Meetings/ Additional Information

May 2016

Madison Water Utility contracted with DN Tanks, Inc. for the construction of the 1.5 million gallon concrete ground storage reservoir on the Well 31 site. The reservoir construction consisted of casting and forming concrete reservoir components on-site, erecting and wire-winding the concrete panels, and applying finish coatings & architectural masonry. The reservoir was completed in May, 2016.

Dec. 23, 2014 - MWU Board Meeting

MWU presented the follow-up energy and upper aquifer well analysis which was requested at the 11/25 Water Board meeting.  We were then authorized to proceed with design concept 1A (detached circular reservoir option with concrete filter backwash tanks). The Water Utility Board has approved an initial design featuring a detached circular reservoir with concrete filter backwash tanks. We are now beginning to work on final design/construction documents as well as beginning the permitting and approval procedures for the proposed facility.
