ATTACHMENT 1 INDIAN RIVER COUNTY DEPARTMENT OF UTILITY SERVICES NORTH AND SOUTH WATER TREATMENT FACILITIES OFF -SITE WELL INSTALLATIONS SCOPE OF SERVICES I. PROJECT DESCRIPTION The objective of this project is to install three new off-site raw water supply wells for the North Water Treatment Facility (WTF) and one new off-site raw water supply well for the South Water Treatment Facility (WTF) . The basis of design for these new wells will be similar to existing wells at each plant. The South WTF supply well S7 was authorized under the existing consumptive use permit (CUP) . However, to add the three new supply wells at the North WTF , the existing CUP will require modification . PBS&J will provide services to modify the CUP to include the three new supply wells and associated additional withdrawal quantities, and the hydrogeological, design and construction phase services required for the construction of the four new supply wells as indicated herein . II. SCOPE OF SERVICES The specific services and tasks to be provided by PBS&J are described as follows : Task 1 — Consumptive Use Permit Modification Application Task 1 . 1 - File Review In this task, PBS &J will obtain and review a copy of the most recent application to renew the CUP ( 1998 -2001 ) , associated correspondence , and SJRWMD staff review comments to identify criteria utilized by SJRWMD to evaluate impacts from groundwater withdrawals and obtain a copy of the electronic input files and description of the groundwater flow model that was used to identify impacts for the CUP renewal . Task 1 .2 - Attend Pre-application Meetings with SJRWMD and County The task covers attendance at two meetings . The first meeting will be conducted between the County and PBS &J . The second meeting will include SJRWMD staff. The objective of the second meeting will be to present preliminary results on the withdrawal impact analysis identified below in Task 1 . 3 and ascertain SJRWMD ' s specific technical requirements for the application , including their requirements for hydrogeologic data, analyses , and estimates of hydrogeologic impacts . Task 1 .3 — Withdrawal Impact Analysis The previously constructed Indian River County groundwater flow model will be used as is , but updated by adding the three new supply wells at the North Wellfield in order to evaluate the impacts from their additional withdrawal quantities . As needed, the updated model will also be used to develop recommended withdrawal quantities and locations for the three new supply wells for minimizing impacts . Historical data collected in past years by the County will be reviewed by PBS &J to revise or concur with previous water demand projection data input for the model .
