| Reverse Osmosis |
|
HISTORY:
The City of Cape Coral utilizes reverse osmosis
(RO) to treat its’ water which is supplied by 23 deep wells. The
majority of these wells are in the lower Hawthorne Aquifer at a depth
of 650
to 700 feet. The RO Plant was built in 1976. Prior to the building
of the RO Plant the City used lime softening. This technology was
abandoned in 1985, primarily due to salt water intrusion. The 3 mgd
Reverse Osmosis Plant of 1976 was expanded to 15 mgd, which allows
the City to keep pace with the growth occurring in Cape Coral. |
