Pinewoods RO Treatment Plant and Wellfield Phase II

STATEMENT OF WORK (SOW) EXAMPLES

EXAMPLE 1 - Project Title: Pinewoods RO Treatment Plant and Wellfield Phase II

A. Introduction/Background

Lee County Utilities (LCU) owns and operates the Pinewoods Water Treatment Plant and related

public water supply wellfield south of Corkscrew Road approximately one mile east of Interstate I-

75. Currently, the wellfield consists of wells withdrawing water from traditional sources, the

surficial and sandstone aquifers. Given the competition for fresh water resources and potential

wetland impacts LCU decided that further development of raw water from traditional sources in

this area was not feasible. Therefore, it was decided that further wellfield development would be

raw water from the Lower Hawthorne aquifer, an alternative source. Lee County has initiated the

construction of Pinewoods Lower Hawthorne Wells and RO Treatment Plant Phase I. In phase I

the storage tank and RO building were completed. The next phase of this project will consist of

completion of the 3.2 million gallons per day (MGD) Reverse Osmosis (RO) Water Treatment

Plant (WTP) and the related Lower Hawthorne Wellfield.

B. Objectives

The objective of this project is to assist in the completion of the Pinewoods Reverse Osmosis

Water Treatment Plant and Lower Hawthorne Wellfield Phase II to help meet the City’s water

supply demands.

C. Scope of Work

Fiscal Year 2007 work will complete construction of a 3.2 mgd water treatment facility and four

Lower Hawthorne Floridan Aquifer Production wells. Work will include construction of RO

equipment, high service pumps, mechanical equipment, yard piping, wellfield piping, electrical

equipment, production wells, monitoring wells, raw water pipelines, and related appurtenances.

EXAMPLE 2 - Project Title: Floridan Aquifer Wells (2) at Dixie Wellfield

A Introduction/Background

The project titled “Dixie Brackish Water Supply / Treatment Facility” is composed of multiple

phases as follows:

• Phase 1 – Construct Two Floridan Aquifer Test Wells

• Phase 2 – Conceptual Plan for Brackish Water Supply and Treatment

• Phase 3 – RO Membrane Pilot Testing

• Phase 4 – Floridan Aquifer Production Well Design & Construction

• Phase 5 – Wellfield Conveyance Facilities Design & Construction

• Phase 6 – Dixie Reverse Osmosis Facilities Design & Construction

This project includes construction work associated with Phase 1, which includes the installation

and testing of two (2) 24-inch diameter by approximately 1,100-foot deep water supply wells to be

completed in the Floridan Aquifer within the City of Fort Lauderdale’s Dixie Wellfield. These wells

will provide raw water to the Peele-Dixie Water Treatment Plant.

B Objectives

The objective of this project is to assist in the construction of a well field necessary to supply

Floridan Aquifer water to help meet the City’s water supply demands.

C Scope of Work

Fiscal Year 2007 work will consist of construction and testing of two 24-inch diameter water

supply wells completed in the Floridan Aquifer. The wells are anticipated to able about 1,100 feet

in depth and will be located at the City of Fort Lauderdale’s Dixie Wellfield. These wells will

provide raw water to the Peele-Dixie Water Treatment Plant.

EXAMPLE 3 - Project Title: Floridan Aquifer Wells (2) and Two (2) MGD RO Expansion

A Introduction/Background

The City of Hollywood WTP requires additional treated capacity to service its existing and

developing customer base. Additional raw water supply to be able to produce additional treated

capacity is required in the short term. This request includes construction of two (2) new Floridan

Aquifer groundwater wells classified as proposed under existing Consumptive Use Permit (CUP).

These wells have previously been identified in the Lower East Coast Water Supply

Questionnaire. In addition, a new 2 MGD Reverse Osmosis (RO) train is required to be built to

increase treated capacity added to the distribution system from the Floridan water supply.

Proposed Floridan Aquifer production wells requested under this application have already been

characterized in the existing CUP. This project converts proposed production wells into existing

test production wells, augmenting available supply from the Floridan Aquifer. Plans to revise the

CUP accordingly are underway.

Construction of new 2 MGD RO train has limited permitting requirements which will be obtained

during the Bid Preparation stage indicated on the attached schedule. Hollywood RO system has

been designed and built for modular expansion. RO train to be constructed will be replication of

existing 2 MGD train and will be fabricated by skid supplier according to pre-established design

specifications.
