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

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
