  1. “ 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

  2. What is Centrale Sewer?

  3. Centrale Sewer is a Permanent, Localized (Distributed) Wastewater( “mini-municipal” ) • Collection • Treatment • Dispersal System

  4. Lakeview WPCP, Ontario – 100 MGDMunicipal Upgrade To Meet New Ammonia Limits IFAS Upgradewith ActiveCell media

  5. Typical “Mini-Municipal” Installation Wise Living Condo Units ActiveCell media

  6. Why Do We Need Centrale Sewer?

  7. Septic Systems

  8. 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.

  9. 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).

  10. 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 !

  11. 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.

  12. Why “Alternative” Systems? • Funding ? (not there!) • Failures ! (septics) • Capacity ? (diminishing) • Build on Un-buildable Lots

  13. Types of “Alternative” Systems 500,000 ATU’s in TX ….. 83% NOT WORKING ! STEP SYSTEM VARIABLE GRADE TRICKLING FILTER VACUUM SYSTEM AEROBIC SYSTEM

  14. THREE STAGES OF THE SOLUTION It is NOT a “Community Septic” System Collection Water Dispersal Treatment

  15. Engineered “Stamped” Systems Fast Permitting under GA General Permit

  16. 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

  17. Conservation Subdivision

  18. 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

  19. Typical Installations Wise Living Condo Units

  20. Clancy’s Restaurant on Estuary

  21. Ducks Bay Homes Near the Beach, Mixed Use

  22. Jericho Village 311 Home Subdivision

  23. Larger Systems to 2 MGD

  24. Liberty Mutual Office Complex

  25. Lowe’s Big Box Hardware Store

  26. Wal-Mart

  27. 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

  28. Collection and Delivery Types • Gravity and Lift Stations - tried and true but EXPENSIVE ! Manholes every 400’ , Deep cuts ! • Low Pressure • Grinder Pumps • STEP Systems

  29. Low Pressure Systems • Pumps Wastewater from Individual Homes, Businesses, Facilities, Communities, etc.

  30. Low Pressure Systems Advantages • Provides Central Sewer • 40-60% Less Expensive • No Fall Requirement • Eliminates Pump Stations • Lower O&M Cost Infrastructure

  31. 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

  32. 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 !

  33. Applications • Complete Sealed Low Pressure System • Gravity Systems are NOT Sealed and Should not be used

  34. Low Pressure Grinder Pumps • Pumps All Waste to the WWTP • Smaller Tank • Lower Head Pumps

  35. 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

  36. 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

  37. Effluent Filter • Zabel/Polylok Filters • 1/16” mesh • High level sensor • Permanent Optional

  38. GOULDS Filtered Effluent • Heads to 650’ • Flows to 25 GPM • Optional Cord Types

  39. AQUAWORX Pump Controller, Data Logging, and Autodialer

  40. 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

  41. AQUAWORX Based on an embedded microcomputer in the pump controller, and a float-less level transducer in the pump chamber

  42. Centralized Management of Decentralized Systems

  43. How do smart controllers help? • Facilitate Centralized Management • Predict a component failure • Allows time and day dependent biological process control • Simulate an onsite operator

  44. 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.

  45. “…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

  46. 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

  47. Trickling Filter Technology Vent Discharge Settling Tank Bioclere™

  48. Trickling Filter Technology • Handles Wide Range of Flows • Handles Wide Range of Temperature

  49. 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

  50. Lotus-Active_Cell media Floating, Large Surface Area, Neutral Buoyancy
