“Smart” or Weather Based Irrigation Controllers (WBICs)

Smart Controllers/WBICs are more efficient:

• Real-time local weather data
• Historical weather patterns
• Pre-programed watering

schedules/restrictions

• Plant type
• Soil Type
• Slope/Sun considerations

Can save up to 20% of water used instantly!

The Smart Irrigation Program “SIP”

• Potential savings analysis performed

before audit/install approval

• Three year program targets:
• Year 1 – top 5% water users
• Year 2 – top 10% water users
• Year 3 – top 20% water users

The Smart Irrigation Program “SIP”

STEP 1 – Initial Site Visit

• Qualified customers will receive a

certified water audit from a licensed RPU contractor

• Assess irrigation system
• Feasibility of controller install
• Feasibility of high efficiency

nozzle install

STEP 2 – Installation Visit

• Installation of smart controller/WBIC

and high efficiency sprinkler nozzles

• Audit results/data used to

program smart controllers

• Audit inventories used to ensure

correct nozzles obtained for install

The Smart Irrigation Program “SIP”

• Program Projections:
• Estimated cost per site $600-$800
• Estimated 700 sites installed over 3 year program
• Estimated average water savings of 20% per site

Recommendations

That the Board of Public Utilities recommend that the City Council:

• Approve the Smart Irrigation Program;
• Approve funding in the amount of up to $200,000 for F/Y 2011-12

and inclusion in the budget for the following two (2) fiscal years; and

• Authorize the City Manager, or his designee, to make any minor,
