EXHIBIT #1 <br />Work Order Number 23 <br />Bulk Caustic Tank Replacement <br />At Hobart Water Treatment Plant <br />PROJECT UNDERSTANDING <br />The existing bulk caustic tank at the Hobart (North) Reverse Osmosis Water Treatment <br />Plant (ROWTP) is more than 20 years old and recent inspection of the interior of the tank <br />showed significant deterioration of the interior lining. The bulk tank is at the end of its <br />service life, and therefore, replacement of the tank is necessary. Ancillary components to <br />the bulk caustic storage tank, such as the tank heater, level transmitter, tank/piping <br />insulation and heat tracing, piping, and containment coatings should also be addressed as <br />part of the tank replacement. The scope of work consists of review and inspection of the <br />existing tank conditions and site, preparation of design plans and specifications for a new <br />tank and associated supply piping, coordination with FDEP, and bidding. <br />SCOPE OF SERVICES <br />Task 1: Review Existing Conditions <br />Consultant will review existing caustic tank and piping at the Hobart ROWTP and <br />evaluate options for a replacement tank. Consultant will develop a phasing plan to allow <br />replacement of the existing tank without interrupting service. <br />Task 2: Design Plans and Specification <br />Consultant will prepare plans and specifications for a replacement tank. Plans will <br />consist of a site plan, tank supports, piping, tie-in details, and general details. Photos may <br />be used to depict details. It is anticipated that approximately four (4) drawings will be <br />prepared. <br />Specifications will be prepared and consist of the replacement tank, associated piping, <br />coating of existing containment area, and demolition of existing tank. <br />Consultant will provide 90% plans and specifications for review and comment as well as <br />final plans and specifications for construction. The plans and specifications will be <br />combined with the sulfuric acid tank replacement project (Work Order #14) to be bid out <br />as a single construction contract. Drawings and specifications will be provided in <br />electronic (.pdf — portable document format) form. <br />C:\Users\lialexander\AppData\Local\Microsoft\Windows\INetCache\Content.Outlook\BYBQCZ4M\20191004 - Hobart Caustic Tank <br />Scope Rev Ldocx Page 1 of 3 <br />
