Results

  • Increased level of cooperation among communities involved Communities formed the Dane-Iowa County Wastewater Commission Positive revenues from the joint wastewater treatment plant generated - Wisconsin Heights School and Village of Cross Plains are considered customers to the plant
  • Estimate that Villages of Mazomanie and Black Earth each will save 12% of the costs they would have incurred had each village built its own treatment facility Villages of Mazomanie and Black Earth also estimate 24% in savings and operation and maintenance over individual smaller plants
  • Project completed $800,000 below the total $11 million project budget Village of Mazomanie and Black Earth save $65,000 - $75,000 annually on operation and maintenance
