requirements Meet possible future requirements
Part of plant upgrade & expansion designs Includes alternatives analysis evaluating various
requirements, effectiveness, and constraints
Facility Upgrades and Expansions
Treatment and Capacity aren’t the only issues to be addressed
Odor, Noise, and Aesthetics are additional issues These have been successfully addressed at JCEC
No odors beyond 25 Feet from any building Average of 10 dBA reduction in ambient sound level
from before construction to after construction Architecture and Landscaping used to blend into
neighboring locations

Regulatory Changes are addressed during NPDES Discharge Permit Renewals Includes: flow quantity, pollutant identification,
loading and concentrations Changes drive plant expansions & upgrades
All Regulatory & NPDES Permit requirements are met or exceeded.
The KPI is the “Wastewater Effectiveness Rate” The goal is 100% treatment
Current Wastewater Effectiveness Rate is 99.62%
Regulatory Issues
Watershed Protection Plan Completed February 2006 Assessed treatment level impacts upon receiving
water bodies Implemented MS4 & annual storm water permit
for all wastewater facilitieso Storm water is monitored per permit
Regulatory Issues
Wastewater Treatment Systems
Plant operations & maintenance staff are constantly trained to advance knowledge and maintain certifications. Certification status is updated monthly
Backup systems, equipment & software used for monitoring wastewater facilities CMMS, SCADA, operations data analysis &
storage, web-based telemetry, onsite & remote access
Wastewater Treatment Reliability
Beneficial reuse of bio-solids Johns Creek Environmental Campus sludge is
sent to compost facility
Treatment Plants
CMOM program approved by Georgia EPD Audits successfully completed in 2011 & 2012 by
EPD Internal audits are done on annual basisoCity Works and Datastream 7i are the CMMS
software used
Capacity, Maintenance, Operation, and Management (CMOM)
Data is used to determine capacity needs for wastewater facilities and collection system and to keep track of maintenance programs, equipment & inventories
Inspection & repairs of: Creek crossings Manholes SSOs Sanitary Sewer Lines & easements
Sewer system cleaning and chemical root control programs
CMOM
CMOM
Infiltration & Inflow Reduction
Majority of sewer lines have been visually inspected via CCTV Defects given a PACP coding & ratings Used to prioritize corrections
Ongoing inspection & repair program to ensure reduction of inflow & infiltration
CMOM
Root Control To apply chemical root control to sewer lines and
manholes to kill root growth Plan to treat up to 80,000 feet of sewer line per
year
Cleaning To remove sedimentation, debris, and grease from
sewer lines and manholes Plan to clean up to 110,000 feet of sewer line per
year

GIS and Computerized Maintenance Management System (CMMS)
Maintain inventory of Water, Waste Water, and Storm Water systems
Complete system that supports asset management, spatial analyses related to the watersheds, and operational maintenance and construction
Includes material, diameter and size, installation date, status, location notes, special conditions, special functionality, etc.
Updated continuously as repairs to the system are completed, the system is expanded, the system is reconfigured, or supporting information is discovered
Field survey work is continuously in process to improve or record the locations of assets
Geographic Information System
The work order management system
is tied directly to the GIS. This gives all work orders a place on the map
and an asset in the system for tracking
purposes.
CMMS Work Order Management
Reports are generated from the work orders
that track productivity, KPIs,
and assist in managing the
work that must get done.
CMMS Work Order Management
Fats, Roots, Rags, Oils, and Grease (F.R.O.G.) Educate about proper disposal and maintenance
Provide information about wastewater treatment standards and practices
Program is offered to schools throughout the County & information is available on Fulton County’s website
Promote internships & have a dedicated education center at Johns Creek Environmental Campus
Public Education and Outreach
Fulton County Code of Laws establishes: Prevention of installation in floodplains & stream buffers Limitations on density in siting septic tanks Residents may petition for sewer connection
Connection to sewer is not required unless the septic system has failed.
Fulton County uses the Garrison software called Digital Health Department. For septic tank conversion tracking purposes, files are organized alphabetically by address.
Pumped septic tank waste is accepted at the Camp Creek WRF
Public Education plays a key role in: Proper use Inspection, Maintenance & Cleaning Staff attends community meetings, provides information via the
Environmental Health webpage
Septic Tanks
Program allows for monitoring and reducing pollutant load and hazardous substances being introduced into the collection system and treatment plants.
Guided by Fulton County’s Sewer Use Ordinance.
EPD approved Industrial Pretreatment Program.
Details, Sewer Use Ordinance, & permit applications available through Fulton County’s website
Industrial Monitoring and Commercial Pretreatment
This program was created to meet a State and Federal regulatory requirement to monitor what industries discharge into the County sewer system
The Industrial Monitoring section issues permits to industries to limit the pollutants discharged into the sewer system, inspects the industries for compliance with County guidelines, and takes action against industries that violate their permits
34 Permitted (significant) industrial users 31 Non-permitted industrial users
Industrial Monitoring
Monitoring & inspection of approximately 1,805 commercial waste generators & pretreatment systems Pretreatment systems are grease traps for restaurants, schools,
churches, hotels, etc., and oil separators for car maintenance and car/truck washes
All new commercial development with a pretreatment system must be reviewed to ensure it meets County standards by the commercial pretreatment program before discharging to Fulton County sewer This includes plan review and inspection Separators discharging to sanitary sewer are covered under this
program
Commercial Pretreatment
All commercial waste generators with a grease trap, oil separator or sand trap that discharge to the county sanitary sewer system are required to have a permit for their pretreatment systems.
Inspections Quarterly & random inspections Verify maintenance is done by owner Nearby grease traps of F.O.G. induced spills
Shares information with sewer maintenance
Commercial Pretreatment
Available to commercial & industrial users of Fulton County’s sewer system Removes sewer service fee on flows not sent into
the collection system Customer must divert at least 25% or more of
their annual water consumption Program is useful for cooling tower operations or
manufacturing processes which consume potable water
22 properties participating in program Approximately 47,644,640 gallons diverted for an
amount of $61,540.76
