Docusign Envelope ID:3EDD0960-FFF6-43E2-8E49-1A7B2008A238 <br /> PLUMMER <br /> 9/12/2024 <br /> EXHIBIT A <br /> City of San Marcos <br /> Recycled Water Feasibility Study and Master Plan <br /> Scope of Work <br /> Background <br /> The City of San Marcos (City) began its first water reuse project in 2000 following the City's <br /> Wastewater Treatment Plant (WWTP) expansion and upgrade from secondary to tertiary <br /> treatment. Extending an 18-inch diameter pipeline approximately 8.5 miles from the WWTP to <br /> a gas-fired power plant in 2000 allowed the City to serve additional reclaimed water customers. <br /> Contracts were executed for extending reclaimed water service to a cement plant in 2007 and a <br /> golf course in 2010 for irrigation and plant functions, offsetting potable water usage from these <br /> locations. <br /> In 2014, the City commissioned the 'Direct Water Reuse Expansion Feasibility Study' in <br /> collaboration with Texas State University (Texas State), funded by the Texas Water <br /> Development Board (TWDB). This study focused heavily on the feasibility of expanding the <br /> City's reclaimed water system to serve Texas State and also explored the use of green <br /> technology as part of an advanced purification system for potable water reuse. The City has <br /> begun discussing installation of purple pipe to serve Texas State's four thermal plants and <br /> shared recreational areas along the San Marcos River. <br /> The purpose of this project is to build on, update, and expand the previous study to include <br /> potential nonpotable uses throughout the City, including environmental restoration, and <br /> municipal, industrial, and recreational uses. In addition, the City is interested in investigating <br /> options for potable reuse, including direct potable reuse. <br /> The report documenting the results of the feasibility study and master plan will be prepared to <br /> meet Bureau of Reclamation (BoR)Title XVI Feasibility Study requirements per Reclamation <br /> Manual Release WTR 11-01. <br /> Basic Services <br /> Task 1: Project Background and Introduction <br /> (1) Prepare a request for information and data needed from the City to perform the study. <br /> Information to be requested will include previous water supply/reuse study reports; <br /> water and wastewater master plan reports; water and wastewater quantity/quality <br /> data; population projections; GIS basemap data; water demands, including wholesale <br /> contracts/obligations; historical reclaimed water usage; reclaimed water contracts; <br /> development plans; and other pertinent information. City will provide Engineer <br /> requested information in electronic format. <br /> 1 <br />
