Geothermal Vaults and HDPE Structures
What is a Structure?• Valve Vault • Manhole• Pump Station• Catch Basin• Junction Box• Wet Well• Sump• Knock Out Pot• Valve Box• Tank• Etc
All of these have been made from HDPE by ISCO Industries
For:
Water/Sewer
Industrial
Landfill
Irrigation
Geothermal
Typical HDPE Structures
Geothermal Structures
Advantages of HDPE StructuresThey are the same as the pipe:• Tough• Flexible• Leak-free• Lightweight and easy to install• Corrosion & Chemically resistantHDPE structures can be prefabricated for
installation savings and higher quality.
Design Elements
• Header/Circuit size• # of Circuits• Location of Circuits• Circuit Valves• Header Valves• Manway• Misc
Header and Circuit configuration
• Header size is typically 4”-10” which does not affect cylinder diameter
• # of circuits and location of circuits will affect length
Location of Circuits
• Standard configuration is for circuits to come out both sides of vaults
• Can offer circuits to exit one side
• Can create unbalanced number from one side to other
Valves for Vault• Standard Valves
typically butterfly valves• Balancing valves and
circuit setters available• Ball valves for purge
ports only- not recommended for circuits
• Typically provide butterfly valves for main shutoff
• New Bypass recirculation
Manway design• Standard Bolted
Cover • H-20 load bearing
available• Variable diameter
with 28” OD standard
• Height can be specified- shipping concerns become a factor with excessive height
Miscellaneous Items
• Ladder (standard)• P/T ports
(standard)• Lights• Electrical outlets• Drain Valves for
main/header
Miscellaneous Items
• Sump• Pump• Pressure Gauges• Thermometers• Drain Valve for
circuits
• Keep in mind this vault is not a mechanical room.
Factory Tested for Leaks• Header and Circuit piping hydrostatically
tested to 100 psi
• Structure tested with 2-3 psi of air to verify vault sealed from groundwater and weather.
• Misc items like sump/pump become unessential if liquid in interior comes from upset conditions, not standard conditions.
Installation Value
• Lightweight– typically less
than 5000 lbs
– Maximum of 15000 lbs for 36 circuits
Installation Value
• Fast install– Compared to
alternate choices, time is measured in hours verses days/weeks
Installation Value
• Simple and Reliable Connections– Circuits and
headers are connected to stubs on vault with Butt Welding or Electrofusion
• Years of Design and Fabrication experience can help prevent installation and operation headaches.
• Choose an ISCO Circuitmaker Vault for reliable strength and leak free performance!
