Storm Water Division

Storm Water division is part of the function of the Public Works Department.  It is responsible for the maintenance of all storm drainage in the public right-of-way within City limits.  The City has two storm water lift stations that provide drainage relief to the flood prone areas of the City.  Each of the stations is able to pump 42,000 gallons per minute into the C3 and C4 canals respectively. 
The City secured and built over $10 million dollars in improvements to the storm water (City’s Drainage) system city wide.   Funds for this project came from the State of Florida and FEMA through collaborative efforts of our Mayor and City Commissioners and District Six Commissioner Rebeca Sosa.


Water Quality Protection

Water connects everything. Beneath all of South Florida is the Biscayne Aquifer, a shallow, porous limestone formation that has historically provided all urban and agricultural freshwater supply. It is recharged by rain and flows from the Everglades and other natural areas.

Our porous aquifer is especially vulnerable to contamination: We live and work over the water we drink. The aquifer and drinking water supply is also vulnerable to saltwater intrusion, particularly as sea level rises. Human activities on land, including past and present development and water management practices, have had an impact groundwater and surface water quality.

Pollutants generated by land-based activities can be conveyed to drinking water wellfields, coastal waters and other natural areas by stormwater runoff or other discharges. 
Miami-Dade County is constantly working to maintain the quality and quantity of our surface water, groundwater and drinking water. This includes, for example, regulation of land uses and activities that may contribute to pollution, monitoring, soil and water remediation, stormwater management, and natural resource restoration.
Sources of water pollution can include improper storage or disposal of liquid and solid waste, stormwater runoff, filling or dredging of surface waters, and even contamination left behind from land uses and practices of the past.
Many of the "point" sources of contamination may be industrial or pretreatment facilities, however industry does not bear all the responsibility for water pollution. Anyone may contribute to this type of pollution by pouring used engine oil in the backyard or storm drain, throwing litter out of the car window, or using too much fertilizer or pesticide at home.
Together we must work together to ensure that the water bodies, groundwater and drinking water that we share will be clean and healthy.

Biscayne Bay

Biscayne Bay and adjoining waters are among Miami-Dade’s most outstanding natural resources. Shallow, clear water, seagrass meadows and coastal wetlands provide habitat for fish and wildlife, buffer the coast against storm erosion, support boating and other water recreation, and generates more than $6 billion per year of economic benefit.
Although most of Biscayne Bay is designated as a State Aquatic Preserve or is part of Biscayne National Park, the Bay remains vulnerable to human activities in the watershed.



Baynanza is an annual celebration of Biscayne Bay, culminating with the Biscayne Bay Cleanup Day in April. Thousands of volunteers pick up tons of garbage at multiple locations along the bay's shoreline.

Stormwater Management

Heavy storms can cause flooding in low-lying areas, especially during the rainy season.
Runoff from streets, parking lots, lawns and fields can convey litter, particulates, fertilizers, oil, grease and other pollutants to surface waters. Stormwater management plans and infrastructure are now designed to trap pollutants, retain runoff onsite, recharge the aquifer, and reduce flooding in the most vulnerable areas.


Surface Water Monitoring

Our quality of life is dependent on clean water that will support and sustain our community needs as well as our environment and economy. To help accomplish this, Miami-Dade County monitors surface water quality throughout the county on a monthly basis.

Wellfield Protection Areas

Miami-Dade County protects groundwater to maintain a clean and affordable supply of drinking water. An important strategy focuses on preventing contamination before it can happen by regulating types of land uses and activities that may generate pollutants.
Efforts focus most on Wellfield Protection Areas, the zones surrounding public water supply wells.

Can the Grease!

The Water and Sewer and Regulatory and Economic Resources Department are working together to minimize the negative impact that grease has on Miami-Dade County's sewage system. Recent studies have shown that most of the grease that is causing damages to this system is coming from single-family, apartment and condo residents. The repairs to the County's sewage system can be costly to taxpayers.

At times, the damage is limited to localized clogs in the pipes of the residence, which can also be very costly for the homeowner or those who are renting. That is why it's not a good idea to pour grease down your kitchen drain or any other sewage pipe.

Keep Your Pipes in Tip-Top Shape this Holiday Season

Be sure to get rid of fats, oils and grease the right way. Don’t pour it down the sink or down the toilet - that can cause a messy backup and ruin your holiday plans. Treat your pipes right.


The solution

After you are done cooking:

  • Pour the hot grease into a metal can
  • Let it cool down
  • Then throw the can into the regular trash.
