This is a service / maintenance or supply contract in Laguna Beach, California. Contact the soliciting agency for additional information.

The City of Laguna Beach Public Works Department invites qualified consulting firms to prepare a Wastewater Master Plan (WMP). The WMP will serve as a roadmap for the City's short-term (10-year) and long-term (20-year) capital improvement program by addressing its aging wastewater system infrastructure. The objectives are: Analyze system hydraulics to identify the capacity deficiencies of the existing system and needed improvements to handle flows from anticipated future developments/redevelopments and from conversion of septic systems located within the City boundaries. Assess the condition of the wastewater collection system and major facilities, determine their remaining useful life, and determine the need for rehabilitation and replacement. Prioritize and recommend the needed improvements to correct existing system deficiencies and to accommodate future growth. Update wastewater system GIS layers and develop updated system maps. The tasks to be completed as part of this project will include, but may not be limited, to items listed below: Provide project management services. Review data on the existing wastewater system and relevant studies/documents. Discuss the wastewater system service area considering the potential changes due to converting areas with septic systems. Discuss regulatory and compliance requirements and well as the impact of the anticipated Direct Potable Reuse (DPR) regulations. Develop unit flow factors, diurnal curves for weekdays and weekends, and peaking factors for use in updating the wastewater system hydraulic model. Develop planning and design criteria for evaluating the adequacy of the wastewater system and design of replacement or new infrastructure. Develop a Geographic Information Systems (GIS) based hydraulic modeling system and calibrate the new model under dry weather and wet weather conditions. Analyze the existing and build out conditions using the model to identify capacity deficiencies in the wastewater system and make recommendations. Update wastewater system GIS layers and develop updated system maps. Identify sewer force mains within the City jurisdiction. Assess the gravity pipeline conditions based on the CCTV inspection results, (compiled in the City's geodatabase), conduct a risk-based condition assessment of the pipelines, and recommend corrective actions. Assess the conditions and life expectancy of the existing lift stations, siphons, force mains, and manholes and recommend a rehabilitation and replacement plan. Develop 10-year and 20-year capital improvement plans. Provide Wastewater Master Plan documents.
