The following text was added to Wikipedia's Desalination page to lend some balance to the discussion. It is a summary of the Tampa Bay Desal project as adapted from the Tampa Bay Water website.
"The Tampa Bay Water Desalination project was originally a private venture led by Poseidon Resources. This project was delayed by the bankruptcy of Poseidon Resources successive partners in the venture, Stone & Webster, then Covanta (formerly Ogden) and its principle subcontractor Hydranautics. Poseidon's relationship with Stone & Webster through S & W Water LLC ended in June 2000 when Stone & Webster declared bankruptcy and Poseidon Resources purchased Stone & Webster's stake in S & W Water LLC. Poseidon Resources partnered with Covanta and Hydranautics in 2001, changing the consortium name to Tampa Bay Desal. Through the inability of Covanta to complete construction bonding of the project, the Tampa Bay Water agency was forced to purchase the project from Poseidon on May 15, 2002 and underwrite the project financing under its own credit rating. Tampa Bay Water then contracted with Covanta Tampa Construction, who produced a project that did not meet required performance tests, and Covanta Tampa Construction filed bankruptcy in October 2003 to prevent losing the contract with Tampa Bay Water, which resulted in nearly 6 months of litigation between Covanta Tampa Construction and Tampa Bay Water. The plant was not fully operational until 2007."
