Domestic Wastewater Facts

  • DEP regulates about 2,000 wastewater facilities
  • Treated Water Discharge Methods
  • Surface Waters (Advanced WW Treatment) – 39%
  • Deep aquifer injection wells – 26%
  • Reclaimed Water Systems – 35%
  • DOH regulates smaller on-site systems
  • About 1/3 of Florida’s population

Wastewater Treatment Permits

  • Issued for Domestic Waste and Pretreated Industrial

Wastes

  • Issued for 5 or 10 years—dependent on compliance

history

  • Includes effluent limitations, monitoring, reporting,

and operations/maintenance requirements

  • Certain statutes require advanced levels of treatment

for discharges to surface waters (nutrients)

  • Grizzle-Figg (Tampa Bay area)
  • Indian River Lagoon
  • Florida Keys

Why do Sanitary Sewer Overflows Occur?

Lack of Capacity System Breakdowns Equipment failure FOG (fats, oils, grease) Non-flushable items Wipes Clog Pipes! Flooding Infiltration and Inflow Aging Systems Illicit Connections

Collection Systems/Infiltration and Inflow

How does Stormwater Enter Domestic Waste Water Lines?

Public Right of Way

Cross Connections Leaky Manholes covers or frames Old Manhole beneath groundwater Cracked/Broken Sewer Pipes

Private Property (Laterals)

Sewer Laterals—broken, roots Open Cleanouts Roof Drain/Stormwater Pond Connections

Notice Requirements

  • 24 hours – Call State Warning Point and District office
  • 5 days updated report due in writing
  • Emergency order—Allows for 30 day updated report

due in writing

  • Rule does not address monitoring after a spill
  • EPA has a the “Capacity, Maintenance, Operation, and

Management Program” (CMOM) for Waste water collection and treatment facilities

  • Each utility is to use the CMOM guide to develop their
  • wn management protocols, including overflow
  • response. This allows a city/county to tailor their

protocols to their government structure

Albert Whitted Timeline

  • 02/1995

Underground Injection Well----Four separate Consent Orders executed for all four Waste Water Treatment Plants due to fluid migration.

Communications

  • DEP is evaluating moving to an electronic reporting

system accessible through our website. Our goal is to be more timely, accurate, more user friendly and transparent to the community. Currently evaluating our resources to make this happen.

  • Notices to the Public. Best handled by the local

government—more familiar with local community and how best to communicate with their citizens.

Moving Forward

9/21/2016 17

  • All Utilities Meetings:

October 2015 February 2016 August 2016

  • 15 Outreach Events
  • Takeaways:

Significant investments in infrastructure Clarify the language of SSOs Make reporting more accurate/less confusing Sharing Resources & Capacity--MOU

DEP is committed to do our part in strengthening all of our partnerships and resolving these problems.
