First Due Tackle Pass It On – Firefighter, Rescue & Extrication Training
Norwalk firefighter Charlie Hillman sent me this picture of some significant calcification in an old ductile iron main. Think about the following questions:
- How does this effect our water supply?
- Besides the water department having a break in the line or a customer noticing a decrease in water, how can we discover this problem?
- Does the calcification increase or decrease pressure to hydrants?
- My guess is this is a 16″ main that is decreased down to about a 6″. What’s the difference in volume?
Pass it on!
