City s wastewater treatment system highly regulated l.jpg

City’s Wastewater Treatment System Highly Regulated

  • FAC 62-610 – Reuse, including land application

  • FAC 62-600 – Wastewater Treatment Facilities

  • FAC 62-601 – Wastewater Monitoring

  • 503 Rule – Federal Biosolids regulations

    Myriad others regarding safety, chemicals, stormwater, etc.


Chapter 62 610 f a c l.jpg

Chapter 62-610, F.A.C.

  • Created in 1989

  • Earlier Rules From 1980

  • Revised in 1999

  • Comprehensive

  • Detailed

  • Consistent With National Guidelines


Ground water standards l.jpg

Ground Water Standards

  • Potable Ground Water

  • Drinking Water Standards

    • Primary Standards

    • Secondary Standards

  • Total Coliforms < 4/100 mL

  • Nitrate - 10 mg/L (as N)


Other controls l.jpg

Other Controls

  • Monitoring

    • Reclaimed Water

    • Ground Water

  • Operator Staffing

  • Access Controls

  • Storage

Nutrient Uptake Rates for Selected Crops


Estimated n allowable at sef l.jpg

Estimated N Allowable at SEF

  • Total acres in pivots = 2000

  • 80% in bermuda grass @ 400 lbs. N

  • 10% in corn @ 210 lbs. N

  • 10% in other crops @ 150 lbs. N

  • Total N allowed per year = 712,000 lbs.

  • Or 1950 lbs/day average

Successes in reducing nitrogen loads l.jpg

Successes in Reducing Nitrogen Loads

  • Stopped applying biosolids in Wakulla County 2001

  • Start-up of Class A dryer March 2004

  • 85% reduction of total biosolids land applied at airport

  • 85% Class A product or Class B to landfill

  • Obtaining more N reduction at TPS effluent


City actions in finding solutions l.jpg

City Actions in Finding Solutions

  • USGS Study - $495 K over three years

  • Treatment Master Plan – Review treatment and disposal options for long-term sustainability

  • Planning additional biosolids treatment to produce 100% Class A Biosolids for reuse

  • Nutrient Management Plan for near-term Farm Operations


Economic impacts l.jpg

Economic Impacts

  • $66 million proposed to upgrade TPS

  • Additional $millions for full nutrient removal (2 ppm nitrates)

  • Could lead to large rate increase

  • Does not include O&M costs


Water utility approach l.jpg

Water Utility Approach

  • Collect Data

  • Develop Alternatives through Master Plan

  • Prepare Plan of Action for Improvements

  • Obtain Funding & Implement Near-term Items

  • Participate in TMDL process to fine-tune Plan of Action and priorities


Tmdl schedule for wakulla river l.jpg

TMDL Schedule for Wakulla River

  • 2007 - Begin developing TMDL

  • 2008 - Adopt TMDL by rule (APA)

  • 2009 - Establish TMDL implementation plan

  • 2010 – Implementation
