Septic System LegislationSeptic System Legislation2010 Legislative Session 2010 Legislative Session ‐‐ SB 550 SB 550 ––Springs Protection Bill included Springs Protection Bill included
Septic System provisions: Septic System provisions: p y pp y p
• Require septic tank owners to pump & inspect systems every five years.• FDOH would enforce compliance statewide. • Failing tanks must be repaired or replaced & brought up to the new
inspection standards by a date certain.• Failure to comply would result in $500/day fines + possible
misdemeanor charges.misdemeanor charges.• Establishes grants for low‐income households for repairs/replacements.

Lee County’s Mandate• Clean Water Act – Lee Co is required by EPA & DEP to maintain a level of service protective of water quality and human health.and human health.
• Lee County Comprehensive Plan POLICY 56.2.1 addresses sewer infrastructure expansion to enhance this level of service “…where and when central sewer is available”. We need a plan to address areas that do not available . We need a plan to address areas that do not currently and may not ever have sewer service. (e.g. determined by low density zoning – DRGR, Buckingham Rural Community Preserve)Buckingham Rural Community Preserve).
Does Lee County need some SepticDoes Lee County need some Septic System regulation?
The entire county is not likely to be seweredCurrently no requirement to maintain and fix Currently no requirement to maintain and fix problemsSeptic systems that are not maintained will eventually failMany septic system owners not aware of what they h d h i khave and how it worksCost to maintain about $100/yr.
Do Septic Systems Really CauseDo Septic Systems Really Cause Nutrient & Bacterial Pollution?
Y if th t l d i d i t ll d d • Yes, if they are not properly designed, installed and maintained.
• The following studies have different research methods e o ow g stud es ave d e e t esea c et odsand soil conditions but a common base‐line condition; No inspection or maintenance requirements ‐
FDEP W ki B i t d d t t d ti t k N – FDEP Wekiva Basin study demonstrated septic tank N contribution to groundwater at 26% as compared to other sources in the basin. h l d d d k– Charlotte County study demonstrated septic tank
contribution consistently at low‐tide and higher concentrations of traceable nutrients and bacteria in higher density neighborhoods.
Wh C i F il ?What Constitutes Failure?System does not function in a sanitary manner: Loss of flush, or discharge of untreated or partially treated wastewater onto ground surface, into ground water, into surface water (64E‐6.001, FAC)6.001, FAC)
Raw Sewage
Should We Use Septic Systems IfShould We Use Septic Systems If They Can Cause Pollution? • Yes, if there are guidelines to follow to prevent pollution:
C i l i h ld b d i l d i – Conventional septic systems should be used in low‐density areas (2 units:1 acre or less) with the bottom of the drain field at least 2’ above the wet season water table for adequate filtration.
– Alternative technologies such as addition of carbon sources in the drain field for enhanced denitrification and tank aeration for drain field remediation should be implemented in older systems and in areas of medium to high density.
All h ld b l i i d – All systems should be on a regular inspection and maintenance schedule to ensure proper function!
d llWe do not manage Septic Systems now. Is it really a problem?
– We have TMDLs in Hendry Creek and Tidal Caloosahatchee for Nutrients & Fecal Coliform. In basins that have no TMDL there is either a verified impairment or TMDLs are pending for one or both
llpollutants.
– Lee Co DOH and NPDES inspectors respond to septic system failure complaints regularly; 250‐300 per year We do not know how many complaints regularly; 250‐300 per year. We do not know how many failures go unreported because homeowner are not required to report.
L C h d d i i f – Lee Co has averaged 318 reported septic system repairs per year for the last decade. Failure can be direct surface or groundwater discharge but may not cause back‐up inside the house.
Bottom line: If a septic system is failing and the toilet still flushes is there an incentive to spend money to fix a failing system?
Other benefits to managing Septic Systems?• If managed Septic Systems can be a tool to phase waste water If managed, Septic Systems can be a tool to phase waste water
treatment upgrades into slow‐growth areas.– E.g. Lehigh Acres has ¼ acre and ½ acre platted areas that are very
sparsely populated. Septic System management or cluster systems ld b d lt ti t i til d it / it i could be a good alternative to sewering until density/capacity is
available to support sewer infrastructure.
• Proactive Inventory & Inspection Can Help Us; Proactive Inventory & Inspection Can Help Us; – Prioritize where sewer expansion programs can be implemented
and where long‐term management & alternative onsite upgrades should be planned.Id if l bl f i l i l j – Identify or rule‐out problem areas for regional capital project planning.
– Justify large scale federal public funding assistance for Septic System upgrade programs. y pg p g

Wh h Al i ?What are the Alternatives?• Status Quo We still have to spend millions to identify and • Status Quo… We still have to spend millions to identify and treat pollution sources to comply with TMDLs. Regional WQ projects are several times more expensive than pollution prevention projectspollution prevention projects.
• Mandate Inspections & Corrective Actions… Improve septic system function ‐> Prevent pollution ‐> Get credit toward system function ‐> Prevent pollution ‐> Get credit toward TMDL compliance AND save money. Follow State lead or draft county ordinance.
• Sewer it all… Very expensive & no incentives in current economy, Not feasible in low‐density areas, Future expansion in low density zoned areas (e.g. Buckingham expansion in low density zoned areas (e.g. Buckingham Rural Community Preserve) will not likely happen due to logistics and expense.
Next Steps• Engage the Legislature to support Septic System mandated Inventory, Inspection & Maintenance Program. Program.
• If the State will not mandate such a program should the BOCC take a proactive role to implement these mandates in Lee County?– Staff has collected data & has expertise to move forward – Staff has collected data & has expertise to move forward at BOCC direction.
– We do not have to reinvent the wheel. There are models i i tin existence.
