“ There are no major obstacles to a decentralized infrastructure for wastewater treatment” Ed Corriveau, Director of Wastewater Planning, PA DEP “Centrale” Sewer WELCOME Mike Millard Southeast Pump & Equipment
Centrale Sewer is a Permanent, Localized (Distributed) Wastewater( “mini-municipal” ) • Collection • Treatment • Dispersal System

The Septic Paradigm EPA Stats: • 2/3 of Land Not Suitable for Septic • Millions of Failed Septic Systems Exist • Serious Pollution Source • Yet 41% of New Residential Housing Built with Septic that are NOT regulated ! Centrale Sewer is regulated by the state… forever.
Centrale Sewer Water (10+ times cleaner then septic water) Septic Water The ultimate goal of an onsite wastewater treatment system is to protect public health and ground water quality. This is achieved by matching the effluent quality to the treatment capacity of the receiving environment. A clean effluent requires less work from the receiving environment (soil).
TMDL !!! • Total Maximum Daily Load is the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards • Section 303(d) of the Clean Water Act • Failure to comply can result in fines &/or penalties to the municipality !
Impacts of High Nitrate Levels from Septic Tanks Although nitrate is necessary, high concentrations can be harmful to the health of the environment, as well as the economy. Babies under 6 months, may get a disease commonly called, Blue Baby Syndrome, or medically called Methemoglobinemia.
Why “Alternative” Systems? • Funding ? (not there!) • Failures ! (septics) • Capacity ? (diminishing) • Build on Un-buildable Lots
Types of “Alternative” Systems 500,000 ATU’s in TX ….. 83% NOT WORKING ! STEP SYSTEM VARIABLE GRADE TRICKLING FILTER VACUUM SYSTEM AEROBIC SYSTEM
THREE STAGES OF THE SOLUTION It is NOT a “Community Septic” System Collection Water Dispersal Treatment
Engineered “Stamped” Systems Fast Permitting under GA General Permit
GA General Permit • Issued by the State • Covers Plants from 10,000 to 150,000 GPD • Permit Allows Installation Anywhere in Georgia • Requires Operator to be “Onsite” 2 hours/month • Zoning Determines Density
Conservation Community • 50% Plus “Green Space” • Preserves Trees/Forest • Minimizes Infrastructure • Environmental protection and enhancement • A healthy lifestyle • A sense of place • A sense of community

The EPA considers decentralized systems as “a goal of the Clean Water Act….to be evaluated on the same basis as traditional sewer…” STAGE ONE: Collection and Delivery
Collection and Delivery Types • Gravity and Lift Stations - tried and true but EXPENSIVE ! Manholes every 400’ , Deep cuts ! • Low Pressure • Grinder Pumps • STEP Systems
Low Pressure Systems • Pumps Wastewater from Individual Homes, Businesses, Facilities, Communities, etc.
Low Pressure Systems Advantages • Provides Central Sewer • 40-60% Less Expensive • No Fall Requirement • Eliminates Pump Stations • Lower O&M Cost Infrastructure
Low Pressure Systems Advantages • No I&I – a Low Pressure System is SEALED !! • Shallow Pipe Installation • Less Disruptive to Environment • Easy to Monitor 24/7 • No Scheduled Maintenance
Patent Pending Features • Measured Flow from STEP-Plus units to check for force-main leaks • Command STEP-Plus units to pump simultaneously to Flush lines • STEP-Plus units maintain a minimum level in each tank to allow for maximum storage • All STEP-Plus units can be commanded to Stop pumping to prevent a spill at the WWTP Protects the Environment !
Applications • Complete Sealed Low Pressure System • Gravity Systems are NOT Sealed and Should not be used
Low Pressure Grinder Pumps • Pumps All Waste to the WWTP • Smaller Tank • Lower Head Pumps
STEP+ System: Can Be Added Existing Homes on Septic • Pumps Liquid Waste to the WWTP • Large 1000 Gallon Tank • Very High Head Pumps FRALO FRALO
SEALED “STEP” TANKS One-piece seamless construction - FRALO tanks are blow-molded to resist leaking and cracking better than concrete and fiberglass. Unlike other materials, they will not rust or corrode and require no additional coating. And they are easier to install! 50 Year Guarantee ! FRALO Sludge & Pump Tanks www.fralo.net
Effluent Filter • Zabel/Polylok Filters • 1/16” mesh • High level sensor • Permanent Optional
GOULDS Filtered Effluent • Heads to 650’ • Flows to 25 GPM • Optional Cord Types
AQUAWORX Pump Controller, Data Logging, and Autodialer
AQUAWORX Controller Features • Highly integrated controller • Built-in modem for communication • Reprogram onsite systems from your office. • Get alarm conditions reported to your PC instantly. • Get weekly/monthly status from each site over the phone line. • Built-in Calendar/Clock • Biological parameter monitoring (smooth flow to WWTP) • Current,Voltage, level monitoring • Solid state switching of pumps
AQUAWORX Based on an embedded microcomputer in the pump controller, and a float-less level transducer in the pump chamber
How do smart controllers help? • Facilitate Centralized Management • Predict a component failure • Allows time and day dependent biological process control • Simulate an onsite operator
SEALED Fiberglass Tanks • Water-tightness. Never rust , made of corrosion-resistant materials, eliminates the possibility of leakage • Strongest, most robust underground storage tanks , 5,000 to 60,000 Gallon • Once installed, require no corrosion maintenance or EPA-mandated corrosion monitoring. • Easy and quick to install because they are lightweight.
“…privatization of wastewater treatment operations offer increased efficiency, cost reduction, environmental benefits, and access to capital for municipalities” (EPA’s Draft Guidance on the Privatization of Federal Funded Wastewater Treatment Facilities) STAGE TWO: Modular Wastewater Treatment
Treatment Technology • Trickling Filter. developed 1964 • Sized to Flow : Typically 300 GPD/home (or less) 100 homes = 30,000 GPD • Fixed Film Process – No Chemicals Reqd. • Reduces BOD & TSS • Meet NSF & EPA • 12,000 Installed Worldwide, 1190 in USA • Up to 70% Sludge Reduction
Trickling Filter Technology Vent Discharge Settling Tank Bioclere™
Trickling Filter Technology • Handles Wide Range of Flows • Handles Wide Range of Temperature
Lotus-Active_Cell • Flows from 40,000 to 2,000,000 GPD • Fixed Film Process – No Chemicals Reqd. TREATMENT EFFICIENCY (mg/l) S.S.T. DBO5 NH4 N NO3 N P < 3 < 3 < 0.4 < 4 < 0.2
