Staff is requesting that the City Council award a professional engineering services contract in the amount of $202,130.00 for DOWL HKM to conduct a study of the City’s wastewater collection system as part of the Integrated Water Plan Implementation projects. DOWL HKM was selected for this study based on City staff review of project proposals submitted by prequalified firms. Morrison-Maierle (MMI), Kadrmas, Lee and Jackson (KLJ), Great West Engineering, and HDR Engineering were other firms considered for the project.

This project includes work necessary to evaluate the existing wastewater collection system and develop and recommend improvements in relation to Infiltration and Inflow (I/I) and remote treatment. One of the major components of this study is to update the City’s collection system model so that it can be used to evaluate future flows for wastewater treatment plant upgrades and/or satellite treatment plants. A collection system flow monitoring plan will be implemented to measure and evaluate the amount of I/I impacting the system. A plan for reducing I/I will also be developed. After I/I reduction and satellite treatment options are identified, they will be screened to determine feasibility, ease of implementation, effectiveness in the near and long terms, reasonable level of success, and areas to apply. This project is identified in the CIP as a FY 12 project. Funding in the FY12 budget is sufficient for the study.

The Council may:
• Award the engineering contract to DOWL HKM; or
• Do not award the engineering contract to DOWL HKM. If this project is not completed, the City will be unable to sufficiently evaluate its sanitary sewer collection system in order to effectively implement an Integrated Water Plan.

The funding for the project was budgeted in FY2012 and the source is wastewater funds. 

Staff recommends that Council award a professional engineering services contract to DOWL HKM in the amount of $202,130.00.
