- Spring activation and testing of existing systems. Each spring turf irrigation systems are activated
and systems are checked thoroughly.
- Point of connection (P.O.C.) to make sure that backflow devices on the system are working
properly and there are no leaks.
- Determine there are no “main line” leaks by confirming no water flow through water meter
and by observing turf areas.
- Testing electric remote valves to assure proper opening and closing of each valve.
- Observe head function, reset sprinkler heads out of alignment, repair or replace any damaged
heads and/or upgrade sprinkler head types to improve water distribution performance.
- Inspect controller and set controller to operate either manually or automatically. Repair,
replace or upgrade controller if needed.
- Summer service (In use) Supervisors in each area are responsible for operating and scheduling
watering of turf in that area.
- Setting system to control watering of turf areas.
- Use of quick coupler in the system to water plants/shrubs and in needed turf areas.
- Adjust controller to meet the needs of seed or newly laid sod grass.
- Observe performance of system and report leaks, malfunctioning heads, valves, or controllers
to the irrigation crew for repair or replacement.
- New Installations Standards
- Design shall consider plant/soil relationship in determining sprinkler head type and its precipitation
- Irrigation systems are constructed with high quality material using Class 21 PVC for pipe,
preferred Hunter and/or Rain Bird products for sprinkler heads, valves, and controllers.
- Irrigation systems to be installed in a good workmanship, professional manner.
- New irrigation systems shall include an automatic rain shut off, solar sync sensor, or an E.T.
smart timer for water usage efficiency.
- New irrigation systems shall be tested for distribution uniformity with a goal of meeting a
factor of 75%.
- Drawings of new irrigation system shall be delivered to Irrigation Department for record
- Water Audits Chosen by random, or by reported problems. We will operate sprinkler systems
and will watch for water run‐off or coverage issues.
- Repair obvious leaks or damaged heads.
- Strategically place water catch cups to test systems distribution uniformity.
- Replace heads or nozzles to create improved watering coverage and uniformity factor, also
reducing run off.
- Adding rain sensor or other efficient water saving devices to system.
- Winterization of Systems
- Keep record of each system and its P.O.C.
- List all systems that need to be blown‐out by air compressor to protect PVC pipe during
winter and proceed.
- List all systems that have drains and locations where drains need to be open for proper
preparation of winterizing system and proceed.
- List all systems that need to have backflow devices removed and stored, and proceed.
- Protect backflows during winter and protect pipes where backflows have been removed.
- Maps and Records
- The Irrigation crew keeps maps and records of all irrigation systems installed on UNL campus
and updates changes as they occur.
- Maps and records are referenced to when new diggings or plantings are about to occur on
