A successful Pumps & Controls installation begins with sound project design, well executed installation, and a thorough start-up procedure.

EPG includes an Installation Guide, Installation Record Form, and Start-Up Checklist in every O&M to help achieve this. Not only are these documents a useful resource during the design stage, they can be used as part of a "flight check" process at installation and start-up.

The following are some best practices we highly recommend to encourage trouble-free landfill pump operation. You will also find links to download each of the documents referenced above.

Installation DOs and DON'Ts

-Do-

• Tailor specifications to each job
• Use qualified and experienced installers & electricians
• Establish good electrical ground
• Adhere to color coding of wiring
• Design properly sized force main
• Include air release valves in force main
• Install pressure gauge in pump discharge line

-Don't-

• Over size pumps
  • Excessive flow rate creates high velocity in sump, pulling in fines
  • Excessive pump head can lead to overload and vibration
• Place control panel too close to riser or sump
• Forget to use seal-offs & not potting them
• Leave excess cable and hose in sump or riser

After running first few days:

• Check that adequate grounding remains
• Check voltage
• Look for signs of power surges (lightning)
• Installation problems may be traced back to:
• Poor connections
• Mishandled parts
• Pump flow rate too high for sump design
• Pumps clogged with HDPE chips or sand

After several months of service:

• Check that adequate grounding remains
• Check voltage
• Look for signs of power surges (lightning)
• Do pumps perform as expected?
• Is there noticeable Gas Effect in play (unreliable level readings)?
