PROJECT #2: Facility Security
Project Goal: “Improve Security at the RO, Raw Water, and Lime Plant.”
Project Objective:
1. Install automated gates at the South Plant, Raw Water, and the North Plant.
2. Install electrically locked doors where rooms contain SCADA controls and are high traffic areas.
3. Install a security system at Raw Water.
4. Install new security fence at the South Plant.
Success Measurement: To have system installed by end of FY07.
Project Narrative: The U.S. “Bioterrorism Response Act of 2001, Title IV, Section 1433” requires water supplies to do a vulnerability assessment and to strengthen security at all the facilities used for the potable water production or distribution. A vulnerability assessment report for the City recommends strengthening (or hardening) our security system in a variety of ways.
1. Install new hardened, automated gates at the North, South, and Raw Water facilities. This will restrict access to employees and will allow other entrants to be screened before being allowed to enter.
2. Monitor security system at the Raw Water Lakes at 951 and US41. This facility supplies ½ of the potable water to Marco Island. In future scenarios, this location will possibly supply Marco residents with an increasing percentage of potable water, as well as irrigation water. The Marco Lakes are a surface water supply and as such have an increased vulnerability that wells do not have.
3. Improve fence line security by removing trees and vegetation, and replacing the top 3 strands of security wire.
4. Install proximity card entry doors where SCADA computers are used.
5. Install new fence at the South Plant and repair fence damaged by Hurricane Wilma at the North Plant and South Plant.

PROJECT #4: Dead End Line Flushing
Project Goal: “To provide a higher quality of water product to our customers. To be in compliance with FDEP dead-end flushing regulations FDEP Rules and Regulations, Chapter 62.555.”
Project Objective:
1. To install automatic or manual flushing facilities for all cul-de-sacs and dead-end water mains throughout Marco Island.
2. To comply with FDEP regulatory rule (62.555.350(2).
3. To provide consistent chlorine levels throughout the distribution system.
4. To reduce water quality complaints.
Success Measurement: To install flushing facilities in cul-de-sacs in FY07 based on available funds.
Project Narrative: Beginning in the year 2004, FDEP mandated that all dead end water mains should be flushed in accordance with the utilities written flushing program. The Utility has an active flushing program to fully meet the requirements set forth by DEP. Approximately 212 flush points need to be installed in the potable water system. This program will consist of excavating dead end lines and installing a manual or where appropriate an automatic method to flush these dead end water lines.

PROJECT #5: Meter Replacements
Project Goal: “To improve meter reading accuracy and reduce time needed to read the meters.”
Project Objective:
1. To replace/or retrofit current water meters with new touch pad read water meters.
Success Measurement: Convert 100% of the meters by the end of FY09.
Project Narrative: Water meter accuracy deteriorates with time. The normal life of a meter is 10 years. The Utility Department should replace approximately 10% per year. This has not been done in the past 3 years. FY06 provided funds to start the meter replacement program. Converting to “touch pad” reads will improve the accuracy of the readings.

Project #6: Replace Water Treatment Plant Reverse Osmosis (RO) Membranes
Project Goal: “To continue the ongoing RO replacement/cleaning program.”
Project Objectives:
1. To replace one set (train) of RO membranes per year.
2. To chemically clean the remaining 5 membrane trains each year.
Success Measurements: Improve system reliability.
Project Narrative: The RO facility has 6 parallel treatment trains. Each train contains 24 membranes tubes. The source water is provided by 15 active brackish wells. This brackish well water enters a series of high-pressure vessels that operate at an elevated pressure. The membranes are located in the center of these vessels. A hydraulic pressure of 350-500 psi is applied to the source water and forced through the membrane pores. The membrane pore size is < .001 micron. This microscopic pore size is so small that it prevents 98% of the dissolved salt and other solids from passing through the membrane. As the membrane ages, the rejection level of the solids decreases, allowing more dissolved solids to pass through the treatment plant.

PROJECT #7: Capital Equipment
Project Goal:
· “To improve reliability of the System Control and Data Acquisition (SCADA) System, expand capabilities of the system, and reduce the number of customers inconvenienced by water shutdowns and subsequent boil water notices.”
Project Objective:
1. To improve reliability and operation confidence of the SCADA system.
2. To annually replace existing inoperable water distribution valves and install new isolation valves for the distribution systems.
3. Rehabilitate and upgrade one of the degasifiers to original specifications. Reduce emissions of hydrogen sulfide in the air at the RO Plant.
Success Measurement: To make initial improvements and establish a foundation, which will be improved in the following years.
Project Narrative: The current SCADA System is an old-style radio-polling system. The server polls hundreds of monitoring sites and does so one at a time. This slow polling causes various control problems or failed communication. The new system is “live” which means it virtually monitors all sites continuously. This allows the operators to monitor hundreds of remote sites with confidence and reliability. This in turn enables the Utility Department to monitor and control with less people and to do so reliably. Purchase various instruments and tools such as: low level TSS meter; ORP system for disinfection; chlorine meter; miscellaneous tools; trash pump; exhaust hood for lab; air chip hammer; air compressor; submersible hydro pump; pipe saw; valve machine;
maintenance crane; 500 gallon fuel tank on trailer; and miscellaneous supplies. Capital Equipment CIP includes funds for the following projects:

PROJECT #8: North Plant Site Preparations
Project Goal: “To prepare the previous County recycle facility for the new finished water storage tank and utilities facilities.”
Project Objectives:
1. Survey the facility site.
2. Identify stormwater management options.
3. Prepare site development plans.
Project’s Relationship to Utility Master Plan:
· The need for additional water treatment production and storage is clearly documented in the Master Plan.
Project Narrative: The new site will be used for finished water storage tanks, pump station, maintenance facility, and administration facilities. The site was acquired from Collier County in exchange for two parcels on Elkcam Circle (purchased by the City in FY06 for $1,450,000) and a parcel at Marco Shores adjacent to the Marco Island Airport. The site development plan will evaluate the feasibility of consolidating utility engineering, customer service, and plant maintenance and operation in one location. Currently the utility rents space for the utility engineering and customer service staff. The annual cost for rental is approximately $100,000.
