Project Timeline

The 2003 Wastewater Master Plan recommended the construction of a Wakarusa WWTP as the preferred and most cost effective alternative to expansion of treatment capacity for the community. The plan based treatment needs on a 2025 projected population of 150,000. That drove the estimated capacity of the new facility to 7.0 MGD that, in combination with the City’s existing wastewater treatment plant, would accommodate that total estimated future population. The plan estimated the cost of the 7.0 MGD facility at $88 million in 2007 dollars. In late 2007 pending analysis of changing economy and population growth, the City put the project on hold.

The following steps took place between the adoption of the 2003 Wastewater Master Plan and through 2009:

• 2005 – Solicited proposals for services for the site identification, evaluation, and acquisition.
• 2006 – Completed the Siting Study that evaluated 7 potential sites and recommended the area at what is now 41^st and O’Connell Road.
• 2007 – Acquired the Wakarusa WWTP site encompassing 538 acres.
• 2007 - NPDES permit issued by KDHE for a 7.0 MGD facility.
• 2007 – City Commission adopts Resolution 6717 for the construction of a new wastewater treatment plant, pump stations, and other improvements at an estimated cost of $88 million.
• 2007 – Basis of Design report for the 7.0 MGD Wakarusa WWTP and improvements to the Four Seasons Pump Station and Excess Flow Storage Facility is completed.
• 2007 – Approved the annexation and zoning of the Wakarusa property.
• November 2007 – Project is placed on hold.
• November 2009 – Issued Notice to Proceed for an engineering services contract for a new Wastewater Master Plan to review the timing of the construction and initial capacity of the new wastewater facility, a comprehensive Capital Improvement Program (CIP), a rehabilitation and replacement program, and a review of the wastewater rates necessary to support all of the needed projects.

In July 2012, the 2012 Wastewater Master Plan was completed and recommended that the Wakarusa WWTP and conveyance facilities be in operation by 2018. The new plan used a revised population estimate of 120,000 capita in 2030 for estimating treatment capacity needs. The plan suggested an the initial size of 2.0 MGD for the Wakarusa WWTP and provided a plan level estimate of expenditures at $64 million over the course of the 5 year Capital Improvement Plan (CIP) for the project.
