The Town of Delavan, Wisconsin, has introduced plans to clean the engineered basins at Mound Road to improve the capture of sediment and thereby improve the water quality in Delavan Lake.
According to the Town , the basins have not been dredged since 2007 and are not longer as efficient at capturing sediment.
The Town of Delavan retained Baxter & Woodman, Inc. (Baxter & Woodman) to outline a plan to either hydraulically or mechanically dredge the Mound Road basins.
There are three basins including the North, West and East basin. A fourth alternative was considered with the goal of staying within the Town of Delavan’s $750,000 initial capital budget.
The alternatives reviewed include the following:
Capital costs for the various alternatives ranged from just over $1,000,000 to over $3,000,000. These costs are in the ballpark of what was expected.
Baxter & Woodman is recommending Alternative 4, whereby the Town of Delavan would direct purchase several pieces of dredging equipment and would enter into an agreement with the Delavan Lake Sanitary District (DLSD) to provide labor for dredging operations.
