EXHIBIT #1 <br />Work Order Number 5 <br />South Oslo Rd Membrane Treatment Plant <br />Membrane Replacement and Process Piping Improvements <br />PROJECT UNDERSTANDING <br />The existing membranes at the Oslo Road membrane water treatment plant are more than <br />10 years old and ready for replacement. Some of the membranes have reduced salt <br />rejection and operate at higher than normal operating pressures. Replacement will <br />consist of removal and disposal of the existing elements, and installation of new <br />membrane elements. Competitive bidding of equivalent elements from membrane <br />manufacturers is recommenced since membrane technology has improved and other <br />manufacturers offer competitive membranes at equivalent performance. The work will <br />be requested through advertising by an original equipment manufacturer (OEM) who has <br />experience performing this type of work. The work will be publicly advertised for <br />bidding through Indian River County (IRC) purchasing department. <br />Due to the age of the existing membrane system and support piping systems, a condition <br />assessment will be conducted to assess reliability of the existing mechanical equipment; <br />feedwater, permeate, and concentrate piping; pipe trenches; membrane skids; small <br />piping systems; and high service pump distribution piping systems. Based on the <br />assessment, improvements will be identified and prioritized according to importance. <br />Documents will be prepared for the improvements identified in the assessment review <br />and be included with the membrane replacement specifications. <br />SCOPE OF SERVICES <br />The following scope consists of membrane replacement implementation and <br />improvements identified in the assessment review for the South Oslo Rd water treatment <br />plant. <br />Task 1— Condition Assessment — Piping & Membrane System <br />The existing membrane system is currently, operating at a reduced efficiency due to <br />membrane degradation from scaling, fouling, and apparent intrusion of sand into the <br />membranes. Consultant will evaluate the existing RO skid performance and normalized <br />data, if available, to determine degradation method and determine if additional raw water <br />quality is needed from the raw water supply wells. <br />Consultant will conduct a one -day condition assessment of the existing RO skid <br />equipment, piping, pressure vessels, manifolds, trench piping, (permeate, concentrate, <br />dump), pipe trench walls/floors/grating, feedwater pumps and piping manifold, high <br />service piping manifold, cleaning piping, and chemical system piping within the trenches. <br />C:\Users\mark.miller\Documents\IRCU\Oslo Membrane R&R\Oslo WTP Membrane Replacement 10.4.2018.docx <br />Page 1 of 4 <br />
