Re: Summary report from Environmental Partners on Wastewater Treatment Facility & Odor Controls
Date: September 22, 2015
The The attached document from Environmental Partners (EP) is a summary report of their assessment work completed over the past several months to address odor controls at the Wastewater Treatment Facility (WWTF). Discussion of the findings was presented to the Water and Sewer Commissioners at their meeting held on September 21, 2015. There was unanimous support for moving forward with Environmental Partners but the Commissioners are just receiving this information and need time to review and evaluate each of the recommendations. There are immediate steps that are under way with support of WWTF staff (ferric chloride dosing changes to impact the high sulfide levels enter the headworks and improving the building components). A phased approach working is recommended and it will take several months to complete full design of the improvements. Major work will focus on covering the clarifiers, addressing the ventilation issues at several locations at the plant and introducing a new biofilter system with engineered media.
A schedule and estimated budget costs for two options are included. We anticipate the work will run in the $3.3M range. We have some funding to address the early stage work and design but will need to borrow additional funds to complete this intensive and critical work. This should occur in early January. Environmental Partners will attend a meeting scheduled by the City Council to review their findings directly. Please recognize that the Water and Sewer Commissioners will be working through the findings during the next several weeks and will be finalizing the direction this work will take with Environmental Partners. My office would be happy to assist in coordinating a meeting with EP, Water and Sewer Commissioners and the public.
