I. Overview

30 years ago – water supply was never an issue
in South Florida

1980’s – salt water intrusion became evident
• South Florida Water Management District (SFWMD) began
reducing consumptive use permits for coastal communities

1990’s – Everglades restoration became an
important environmental issue
• SFWMD began restricting water supply
• CERP policies diverted water supplies to the natural
systems, requiring utilities to seek alternative water supplies
Overview, (continued)
15, 2007 – SFWMD approved
Lower East Coast (LEC) Water Supply
Plan Update
 February
 Plan
requires all local governments to
adopt their water supply facilities work
plans by August 15, 2008
II. History
1951 – City of Hallandale Beach built
water treatment plant – 3 mgd
- Water supply – local wells in Biscayne Aquifer
1968 – In anticipation of extensive development,
City built addition to its water plant:
10 mgd capacity
- Water supply – 8 local wells in Biscayne Aquifer
History, (continued)
1980s – Early 1990s – SFWMD restricted
City’s consumption use permit to 3.5 mgd
- City was required to purchase water from North

membrane treatment plan to meet all
current and future water needs of the
City.
- Water supply was assured from Brian Piccolo
Park
- SFWMD was very supportive
- Plant capacity was 6 mgd (expandable to 15 mgd)
- Cost: $22 million
History, (continued)
