CITY COUNCIL AGENDA ITEM 6A STAFF ORIGINATOR: Diane Hankee, City Engineer MEETING DATE: December 23, 2019 TOPIC : Resolution No. 19-183, Accepting Quotes, and Awarding a Construction Contract, Irrigation Controller Upgrades Project VOTE REQUIRED: 3/5 Vote Required INTRODUCTION Staff is requesting authorization to accept quotes and award the construction contract for the Irrigation Controller Upgrades Project. BACKGROUND On May 13, 2019 the City Council approved the Rice Creek Watershed District (RCWD) Stormwater Remediation Cost-Share Grant agreement. As part of the City’s ongoing water conservation efforts, staff has targeted reduction in water use for irrigation as a primary means of meeting the City’s conservation goals. There are additional indirect savings in terms of water system infrastructure from reduced peak season water demand. The new controllers will allow the City to use less water and operate irrigation systems centrally. The irrigation volumes at the targeted locations use an average of 9.2 million gallon annually. The use of smart controllers (weather based system) and/or soil moisture sensors have been found to reduce water use by up to 50%. This would result in 4.6 million gallons annually, representing approximately 3.4 days of water use for the entire city. The benefits of the remote water management system include: • Central Control – Ability to start and stop irrigation schedule on a smart phone or tablet via App. • Weather Based Control – Use current weather and evapotranspiration data to irrigate only when needed. • Flow Sensing and Leak Detection – Can easily monitor flow rate and water use. Real time look at system and instant alert of leaks. • Pressure Regulation – Optimizing pressure to significantly reduce wasted water. The Irrigation Controller Upgrades Project includes:
