Project Description

This project consisted of constructing two water quality ponds for sediment control and water quality enhancement at the Richmond New Paris Pike Landfill. Each pond consists of an earthen embankment, a riser pipe with trash rack, a discharge pipe, an emergency spillway, and a forebay to enhance water quality. The ponds were designed with forebay settling pools to remove the larger sediment particles, and riser pipes with multiple rows of perforations to regulate the release rate and maximize sediment removal. The total water surface area covers approximately 6 acres of land. The ponds were constructed to control the 100-year, 24-hr SCS Type II storm event. The water quality basins were constructed in conjunction with the Phase 3C disposal area construction to minimize costs.
 

Scope of Engineering & Professional Services

CBBEL’s services encompassed construction plan preparation, construction management, and construction quality assurance for the two water quality ponds. CBBEL staff prepared detailed construction plans and specifications, bidding documents, and quantity take-offs for the project. The construction plans were based on landfill hydrologic and hydraulic modeling that was performed by CBBEL. CBBEL staff also performed construction management activities during the project, including contract management, contractor coordination, survey coordination, budget control, and scheduling. CBBEL’s services included part-time construction quality assurance activities for the ponds, consisting of inspection and documentation during construction. The ponds were designed and constructed to meet the Indiana Department of Environmental Management (IDEM) detention standards for landfills.  CBBEL obtained necessary IDEM permit approval before construction started.
