Irrigation Assessment Scoring
www.fh.az.gov
Irrigation System
Issue: System undersized; constant irrigation system clogging
causes incorrect perception of poor turf quality
Recommended Option ($$$$$$): Replacement of irrigation
system & controller and upsize main pipelines
Alternative Option ($$): Keep existing system, additional
maintenance hours with continued negative public perception
Cost Indicator:
$$ = <$20,000
$$$ =<$50,000
$$$$ = <$100,000
$$$$$ = <$500,000
$$$$$$ = >$500,000
Alternative Option ($$$$$$): Irrigate
w/ non-lake water (separate storage
tank). Potential to negative impact
lake aquatic life due to increased
salinity.

Fountain Pump Variable Speed Drives
Issue: Fountain pump motors lack speed control; less energy efficient
Recommended Option (0$): Maintain existing constant speed motors
due to short duration of operation
•capital expense exceeds electrical savings over VFD lifespan
Alternative Option ($$$$$-$$$$$$): Install VFDs, new outdoor
switchboard; building modifications required to meet Code; additional
cooling, new conduit and cable

Fountain Control System
Issue: Fountain control panel lacks communication to Town
network
Recommended Option ($$$):Install new control panel with
PLC and add cellular link
•PLC can provide real time data to O&M staff for
equipment status; provide fountain status to website
for public (countdown or if too windy)
•Cellular link can include irrigation system information
Alternative Option (0$): Maintain existing control panel

Issue: Age exceeds manufacturer’s life expectancy; lacks modern safety
Recommended Option ($$$$): Refurbish equipment using Direct
Replacement Kit coupled with field testing to modernize & extend life
expectancy

Arc Flash & Short Circuit Analysis
3
2
Arc Flash Analysis –Code recommended safety analysis to
prevent personnel / equipment damage when working on
“live” equipment
Short-Circuit Analysis –identifies if only the upstream device
trips if fault occurs
•All existing electrical equipment adequately rated to
withstand maximum fault levels
Recommendation ($):Install arc flash & shock risk labels on all
existing electrical equipment.
www.fh.az.gov
CONCLUSIONS
www.fh.az.gov
Conclusions
•Some equipment exceeds typical useful life but in good
condition; extend life with additional specialized
maintenance and testing
•Immediate Recommendations:
•Replace check valves
•Repair pump house intake screen
•Install arc flash labels on electrical equipment
•Upgrade to PLC control
NEXT STEPS
•Plan / logistics for future liner repair / replacement
