The City of Calabasas finished the
installation of a citywide Smart Irrigation Controller system in
consolidated 58 pre-existing controllers into 52 weather based
evapotranspiration smart controllers. All city-owned and managed
facilities such as street parkways, medians, city parks and freeway
interchanges have been upgraded to the new system.
The overarching goals of the
citywide Smart Irrigation Control System is to reduce water used by
the City of Calabasas for landscaping purposes by a minimum of 20%
while significantly reducing the amount of urban run-off entering
both of the watersheds the City of Calabasas straddles.
The City of Calabasas began this
project before the onset of the State of California's worst drought
in recorded history. Water conservation is now an issue of greater
importance in California, landscape irrigation is harder and harder
to justify as sub-surface water supplies are strained. This
technology is essential for the reduction water waste and
Phase two was completed and ready
for use in January 2015, and constitutes a major upgrade and
expansion of reclaimed water irrigation system on Thousand Oaks
Boulevard. Approximately 3 1/2 acres of parkways and medians, 11,000
linear feet of new recycled (purple) irrigation pipe were installed;
six remote control valves (RCV) were added; deep watering bubblers
were installed on both sides of all trees; and 1,500 drip bubblers
were installed for shrub and plant irrigation of the landscaped
right of way area.
- ICentral sends daily
Evapotranspiration (ET) data to controllers that adjust watering
durations for each region.
- Local weather satellites can
send controllers real time weather information that can be used
to calculate appropriate irrigation durations per station-.
- Each controller can be
accessed using a computer, tablet, or Smartphone to remotely
shutdown and activate during rain events as needed.
- Some controllers with master
valves and flow sensors will shut down automatically if there is
a broken line or irrigation heads show an excess flow.
- Each controller can alert via
email and text if there are any problems with communication,
excess flow, or scheduling changes.
- Water savings annually can be
up to 15-20% with smart controllers.
- Less use of potable water and
expanded use of reclaimed water.
