Cost reduction 

  • Asset management

Preventative maintenance extends the useful life of pipes

  • Chemical demand

Reduce chemicals needed to battle Hydrogen Sulfide Issues – in turn leads to less customer complaints

  • Pumping costs

Can significantly increase flow or discharge rate

Why?

slide-4
SLIDE 4

  • Reduce discolored water complaints
  • Improve water quality compliance
  • Reduce biofilm deposits
  • Reduce THM production
  • Remove iron and manganese build up

Why?

Dallastown Borough, PA

Ice Pigging WW Force Main Improves Pumping Efficiency

4” Force Main Pre and post pump test results: Date Pump 1 Pump 2 10/1/2012 257 gpm 256 gpm 1/14/2013 334 gpm 325 gpm 29.9% increase 25.9% increase

 By cleaning the force main and improving flows over

29%, the Borough can postpone the capital improvement project, allowing that money to be used more effectively.

Middlebury Wastewater, VT Ice Pigging WW Force Main Improves Pumping Efficiency

  • Original plant design flow rate was 6.2 mgd.
  • Decrease in flow rates – Industrial discharge

included Cabot Cheese and several breweries.

  • 10/4/13 flow rate was 5.62 mgd (3,904 gpm).
  • 10/7-10/28/13 conducted 9 IP runs on 12,000 of 16”

& 18” DIP and PVC mains.

 Pre and post pump test results:

  • Date

Two Pumps Flow Rates

  • 10/4/2013

5.62 mgd (3,904 gpm)

  • 10/28/2013

6.26 mgd (4,347 gpm)

  • 11% increase (640,000 gpd or 444 gpm)

 By cleaning the force main, flow rates increased to

6.26 mgd (4,347 gpm) for an approximate 11% increase in flow.
