All rights reserved. <br />This is EXHIBIT A, consisting of pages, referred to <br />in and part of the Agreement between Owner and <br />Engineer for Professional Services dated , . <br />Engineer’s Services <br />Article 1 of the Agreement is supplemented to include the following agreement of the parties. <br />Engineer shall provide Basic and Additional Services as set forth below. <br />PART 1 – BASIC SERVICES <br />A1.01 Study and Report Phase <br />A.Engineer shall: <br />Phase 1 – Distribution System Water Quality Assessment <br />Task 101 – Background Investigation <br />Engineer will perform a background investigation to review available historical information <br />related to the Owner’s Water System. Relevant information anticipated to be requested of the <br />Owner consists of the following for a period of 5 years: <br />Existing points of entry and distribution system water quality <br />Regulatory compliance data (all historical lead and copper rule data will be evaluated) <br />Customer complaint data <br />Confirmed distribution system piping and service line material inventory, in GIS <br />Current distribution system operations information, such as tank levels, and flushing <br />programs <br />Engineer will complete hydraulic modeling simulations under two relevant operating conditions <br />to establish source plume boundaries and percentage of source blending occurring throughout the <br />distribution system. It is assumed that the two operational scenarios will reflect a typical <br />maximum day demand condition and minimum day demand condition. Results of the distribution <br />system hydraulic modeling including water age, flow direction change, and changes is water <br />source will be documented in tabular and graphical form. <br />Up to two coordination conference calls on the hydraulic model scenario development are <br />included. Monthly demand data from 2014-2018 provided previously as part of the Hydraulic <br />Model Development & Calibration project will be reviewed to determine seasonal peaking <br />factors for developing the minimum demand scenario. The calibration scenario will be used to for <br />the maximum day simulations.
