Phase I –Biosolids – Complete by August 2018The Wastewater Treatment Facility stores solid residuals from the treatment process after anaerobic digestion in three 1.2 million gallon tanks. Issues with longer hauling distances and weather variations make it difficult to land apply the entire amount of biosolids that are produced in some years. Seeking review of other solids treatment options, handling and disposal practices to augment or replace the land application and assure adequate capacity to cost effectively dispose of the solid residuals produced at the facility.

  • Review data from sludge treatment and disposal process including solids production, treatment, disposal and land application records.
  • Work with City staff to assemble and review cost data for the current program.
  • Project future sludge volumes based upon flow increases to the plant.
  • Work with City staff to develop a list of viable options for solids disposal.
  • Develop an evaluation method to assist the City in selecting options for both near-term and long-term solids disposal. Include capital and life cycle operating costs, regulatory and treatment impacts, staffing needs, and any other factors that are identified during the course of the study.
  • Provide a planning level report containing recommendations, time frames, and cost projections for both near-term and long-term changes to the solids handling and disposal process.

Phase II – Treatment Plant Asset Inventory and Assessment –Complete by Sept 2018

  • Evaluate the physical condition and biological performance of the various treatment units for average and peak flows, include estimates of remaining useful life, capacity and demand limitations, operation and maintenance concerns, and identify areas that add risk in meeting current regulations.
  • Evaluate space needs of the plant administration and lab.

Phase III – Treatment Plant Master Plan – Complete by May 2019

  • Provide insights on future regulatory and effluent limit changes.
  • Project the future flows and loads the facility may be required to treat.
  • Evaluate whether modifications to the plant process are warranted, based on projected flows and loads.
  • Predict how and when the plant will fail to meet future needs.
  • Outline strategies or alternatives to upgrade existing treatment units determined to be inadequate for future conditions or currently in poor condition.
  • Provide recommendations for phasing of work considering operations, constructability, and financing.
  • Develop budget level cost estimates for needed improvements.
  • Prepare and present to City staff and Commission a final report containing detailed conclusions and recommendations on preferred alternatives for capacity, reliability, efficiency, safety, security and longevity of all aspects of the treatment plant. The report will contain preliminary design layouts and cost estimates for the recommended alternatives.
