Low Pressure Sewer Systems The MYTHS??? The REAL story!!! The Path to Success with your Next LPSS
The Myths A system can’t work with such small pipe and so many pumps? Low pressure sewer systems are “experimental” Low pressure sewer systems have been perceived as a “stop-gap” measure, used only when all other methods have been ruled out
The myths ….continued Low pressure sewer systems are for Rural areas only! Low pressure sewer systems will not work in flat, highly populated areas
The Myths…part 2 Low pressure sewer systems are a dismal failure and they should be outlawed! Low pressure sewer systems are a source of constant maintenance and they will cause a municipality to go broke! Low pressure sewer systems will grind up dogs and cats and anything else that gets close to the system!
Myths…..cleared up Hydraulic studies and practical experience prove that systems with 1,000’s of pumps and pipe no larger than 6”-8” will function very well Low pressure sewer systems have been in operation for over 30 years Low pressure sewer systems have now been placed in the forefront of engineers “tool boxes” for corrective sewer measures
Myths…..cleared up Low pressure sewer systems are being utilized in all sorts of settings: Rural, urban, suburban, etc. WITH GREAT SUCCESS I MIGHT ADD!! Low pressure sewer systems are being used in as many areas with flat topography as they are in wet, rocky or hilly locales
….the myths unplugged Low pressure sewer systems have had the greatest success rate of any technology produced during the great “Water Act” movement. The industry has evolved and continues to perfect the system and it’s multiple technologies.
….the myths unplugged (part 2) Low pressure sewer systems when properly designed and installed are no more a maintenance concern than conventional gravity systems with manholes, lift stations and deep piping systems. Most LPSS owners find that with proper operation of the systems they have fewer service calls than with their conventional systems
…homeowner myth #1, the BIG one cleared up! Low pressure sewer systems, specifically the grinder pump stations, DO NOT grind up your dogs, cats, neighbors kids or anything other than normal residential sewage!
The Real Story The real story on LPSS is that a properly applied, designed and installed system will provide the owner with years of trouble-free operation and a continuing solution to difficult sewer applications. Follow along for “The Rest of the Story”
Low Pressure Sewer Systems LPSS consists of the following components: Grinder Pump Stations Small Diameter Pipe System Air/Vacuum Release Valves System Isolation Valves
Low Pressure Sewer System Design Parameters Small diameter piping system with standard ASTM design minimums Multiple pump system design with calculated flows/heads Growth designed into system with no major additions Ability to manipulate changes into system with little design impact
Low Pressure Sewer System Installation Guidelines Piping Methods Open Trench or Directional Boring Piping Materials High Density Polyethylene or PVC Cleanouts, Air/Vacuum Release Valves, Curb stops, Check Valves Pump Station Installation Specification tightly adhered to
Low Pressure Sewer System Installation Guidelines Electrical Connections Standardized Start-up and commissioning of system should include complete system testing, operation of all components verified by the individual manufacturer the contractor and the owners representative Training of post-project contractors recommended
Low Pressure Sewer System Maintenance Guidelines Develop a tracking program for system components Institute program for proper response to system problems Identify items in system that may require maintenance: i.e. grinder pump station floats, electrical boxes, main valves, air/vacuum release valves, etc. and build a program for tracking their maintenance schedules
Low Pressure Sewer System Maintenance Guidelines Develop mapping of system to enable easy identification of system components Institute “Homeowner Education Program” to inform them of the “Do’s & Don’ts” of using a grinder pump station
Low Pressure Sewer Systems Remember!!! Ignore the myths, get the REAL story, then follow this easy path to success with your next LPSS APPLICATION DESIGN INSTALLATION MAINTENANCE Thank You
