Water Disposal

What is Underground Injection Control (UIC)?

In Florida, UIC is a common technology that has been in use since the 1960s by municipalities, counties and industry to safely dispose of pre-treated wastewater and excess stormwater into self-contained geologic formations deep underground.

The geologic formations where wastewater is disposed are deep underground and are separated from drinking water sources by naturally occurring confining units (typically thick sequences of impermeable rocks and clays).

Regulated and monitored by the Environmental Protection Agency (EPA), UIC is an important, environmentally friendly alternative to releasing pre-treated water into surface water bodies, streams and rivers.

UIC deep well disposal provides an important water management option to reduce surface water discharges and provides a higher level of protection to surface water bodies from wastewater spills caused by storms or other natural events.
