DEVELOPING AN ACCURATE MODEL TO SUPPORT COST-EFFECTIVE COLLECTION SYSTEM DESIGN SOLUTIONS: METHODS AND BENEFITS

The goal of the Northern Kentucky Sanitation District No. 1 (SD1) was to develop and utilize highly accurate hydraulic models of their collection system to aid in their future planning and design needs. The Southern Kenton County study was undertaken to examine the largest portion of SD1's separate sanitary system to identify cost-effective wet weather solutions. The Lakeview pump station that drains this system was recently upgraded, and the effects of this upgrade on the collection system were not fully understood. The existing hydraulic model containing the Lakeview pump station was refined, calibrated, and used to analyze this upgrade, future development, and the impacts of this growth on the collection system. This analysis helped to further understand the Lakeview tributary system, prioritize problem areas, and develop a set of alternatives to reduce wet weather concerns throughout the separate sanitary system. Selection and design of final alternatives for this collection system will be based on the predicted water quality benefits within the Southern Kenton County watershed. The hydraulic model will be used to help predict and quantify the water quality benefits for any future alternatives.
