Exhibit B DI Water System Maintenance Scope of Work final 71916.pdf

This is a Scope of Work document for a deionized water system maintenance contract. The document outlines comprehensive maintenance procedures for a water filtration and treatment system, detailing semi-annual pre-filter replacements (1.0 micron 30" meltblown filters with o-rings, specifically Graver model GWT131A30-3), semi-annual post-filter replacements (Parker 0.2 absolute 30" filters), monthly R/O pre-filter installations and replacements (GE 20" 1.0 micron meltblown DOE Puretrex models), annual UV lamp replacements (3084 model), and quartz sleeve maintenance. The scope additionally includes twice-yearly mixed bed servicing with an estimated 12 bags of 40-pound salt per year, annual system sterilization and flushing performed on weekends, annual filter membrane cleaning, water softener resin checks and replacements as needed, and check valve installation on the storage tank overflow line. The document indicates that additional maintenance items are anticipated to be added or removed following a pre-bid walkthrough meeting, with an updated scope of work to be distributed to attendees.

The document includes a cost estimate table framework but does not provide specific pricing information for most line items. Service rates are referenced for regular hourly work (Monday through Friday, 8:00 a.m. to 5:00 p.m.), Saturday/overtime rates, and average emergency response time, though specific dollar amounts are not populated in this version. The document explicitly notes that additional pricing information will be provided separately and welcomes bidder comments and revisions to the proposed scope of work prior to finalization.
