SUMMARY EXPLANATION:

The City of Yakima’s (City’s) Wastewater Treatment Plant operates and maintains six anaerobic biosolids digesters to meet the regulatory requirements for Class B biosolids production in accordance with its NPDES permit with the Department of Ecology.  The digesters require periodic cleaning for the removal of un-digestible inert materials in order to maintain adequate treatment capacity and periodic interior surface re-coating to maintain structural integrity. 

 

City Project No. WF2489 was established for the cleaning of four of the digesters and the re-coating of the plant's largest (one million gallon) primary digester.  The City utilized the procedure established by the State of Washington for competitively bidding projects.  Two contractors submitted bids, with Selland Construction, Inc. submitting the lowest bid of $1,505,667.92.  See attached contract. The project is funded by Wastewater Facility Capital Fund 478.
