Department Recommendations
DOH Recommendations 1
•Set a discharge limit of 10 milligrams per liter of
total nitrogen for new systems, systems being
modified, and for existing systems in the primary
and secondary Wekiva Study Area protection
zones.
•Prohibit the land-spreading of septage and
grease trap waste in the Wekiva Study Area.
Septage waste would be required to be
disposed of at wastewater treatment plants.
DOH Recommendations 2
•Evaluate the economic feasibility of sewering versus
nutrient removal upgrades to existing onsite sewage
treatment and disposal systems. A phased-in approach
to replacing the remaining existing systems should be
developed with a target completion date of 2010.
•Establish new regional wastewater management entities
or modify existing ones to oversee the maintenance of all
wastewater discharged from onsite sewage treatment
and disposal systems in the study area. These
programs should take the privatization approach and
contract with existing licensed septic tank contractors.
The Recommended System
A Nutrient Reducing System with Drip Irrigation
System Construction and
Operating Costs
• Conventional system
$5,500 to $7,000
No operating permit
except IM zoned areas
• Proposed system
$7,500 to $9,000
$100 operating permit
Every 2 years
$140 in annual
electric costs
Maintenance agreement
DOH Rule Adoption Process
Rule Adoption
•Primary issues are to adopt a nitrogen limit and
require drip irrigation for onsite systems
•Permitting process is already in place in the rule
•Public Input - Technical Review and Advisory
Panel (TRAP) established by 318.0068 FS
•Formal TRAP Meeting to review proposals in
May, 2005;
•Anticipated rule implementation as early as
March 2006
