 Phase II Disinfection Project

12/16/15
The U.V. System is installed for disinfection. It will disinfect our plant effluent before it enters the outfall pipe. At this point we are running the system to get a 100 hour burn in time on the bulbs. Come March we will start system up for our disinfection season. Season runs from March 15th till Nov. 15th. The first season will be for performance testing to see if we can comply with set limits for E-coli. The system installed is a high quality unit and should put us in compliance.

We are into the second year of disinfection.  The new Ultra Violet system was tested last season and we are able to meet the permitted E.coli limits. No other phases are needed to meet the bacteria limits.

New Water Resources Recovery Facility Project

With a major part of the plant being over 50 years old its dependability is fading. The old plant has been well cared for but it can't fit today's demands. Over the last year we have been working with engineers on a plant facility plan to bring the plant up to today's standards. Through this Facility Plan we looked at different options and decided that updates to the existing Trickling Filter Process would not be the best option for the long term. We have toured different plants and have came away with some good ideas from them tours. The new plant will be a activated sludge process using Oxidation Ditches.  The new WRRF will be in line to meet new effluent nutrient regulations, have capacity to treat major weather events, and also open opportunities for city growth with added capacities.

Design of the new activated sludge using Oxidation Ditch Process is completed.  Bidding and start construction late summer 2019.  Final Completion late 2021
