Irrigation Service & Repair in Denver, CO
Smart irrigation technology, expert system maintenance, and proven water conservation strategies that have saved hundreds of thousands of gallons for Denver properties since 1975.
Complete Irrigation Management for Denver Properties
Water is Colorado's most limited natural resource, and irrigation systems are the single largest controllable factor in your property's water consumption. JLS Landscape & Sprinkler provides full-service irrigation management that maximizes landscape health while minimizing water waste -- a balance we have been perfecting since 1975.
Our irrigation service team handles everything from spring activation and system evaluation to mid-season monitoring, damage repair, and fall sprinkler blowout winterization. For properties with aging or inefficient systems, we design and install upgrades that incorporate smart controllers, sensor technology, and drip conversion to dramatically reduce water consumption.
Whether you manage a 50-zone commercial campus or a residential property in Douglas County, our technicians bring the same diagnostic precision and water-saving expertise to every service call. We serve both commercial clients and residential homeowners expanding back into the Douglas County area.
Smart Irrigation Systems That Save Water and Money
JLS specializes in advanced irrigation technology that responds to real-time conditions rather than running on a fixed timer. Our smart irrigation installations and upgrades consistently reduce water usage by 20-40% compared to conventional clock-based systems.
Signal-Based Smart Controllers
Wi-Fi connected controllers that receive real-time weather data and adjust watering schedules automatically. Monitor and control your system from any device, receive alerts for anomalies, and track water usage over time.
Historic ET Controllers
Evapotranspiration-based controllers calculate how much water your landscape actually needs based on historical climate data, plant type, soil conditions, slope, and sun exposure -- then deliver exactly that amount.
Rain and Freeze Sensors
Automatic shutoff when it rains or temperatures drop below freezing. These simple sensors prevent the most common form of water waste -- irrigating during or immediately after rainfall.
Soil Moisture Sensors
In-ground sensors measure actual root-zone moisture levels and communicate with the controller to water only when the soil needs it. Eliminates overwatering in shaded areas and ensures adequate moisture in exposed zones.
Wind Sensors
High winds cause sprinkler spray patterns to miss their targets and waste water through evaporation. Wind sensors pause irrigation during high-wind conditions and resume when conditions improve.
Flow Sensors and Leak Detection
Flow meters installed on the mainline detect abnormal water usage that indicates leaks, broken heads, or stuck valves. The system alerts property managers and can automatically shut down zones to prevent water waste and property damage.
Seasonal Irrigation Service Cycle
Colorado's dramatic seasonal shifts demand a disciplined irrigation service calendar. JLS manages your system through every phase of the year so you never have to wonder whether your irrigation is running correctly or wasting water.
Spring Activation
System startup, controller programming, zone-by-zone testing, head adjustment, and leak inspection after winter dormancy.
Mid-Season Monitoring
Weekly inspections, run-time adjustments for heat waves, sensor calibration, and responsive repair for damage from mowing, vehicles, or weather.
Fall Winterization
Comprehensive sprinkler blowout using compressed air to clear all water from pipes, valves, and backflow assemblies before the first hard freeze.
Winter Watering
Manual supplemental watering during dry winter periods to protect trees, shrubs, and perennials from desiccation damage caused by Colorado's arid winter conditions.
Water Conservation Strategies
JLS has saved hundreds of thousands of gallons of water for Denver-area properties through smart technology, drip conversion, and disciplined seasonal programming. Our approach aligns with EPA WaterSense guidelines and local water authority requirements.
- Drip irrigation conversion for planting beds, tree rings, and shrub zones
- Rotary nozzle upgrades that apply water more slowly for better soil absorption
- Seasonal programming adjustments -- spring run-times are different than August run-times
- Zone-specific scheduling based on sun exposure, soil type, and plant material
- Head-to-head coverage audits to eliminate dry spots and overspray
- Pressure regulation to prevent misting and wind drift
- Water budget tracking and monthly usage reporting for property managers

Smart irrigation systems typically reduce water consumption by 20-40% compared to conventional timer-based controllers. The exact savings depend on your current system efficiency, property size, and landscape composition. For a mid-size commercial property in Denver, this can translate to thousands of dollars in annual water cost savings. JLS has saved hundreds of thousands of gallons across our client portfolio since adopting smart irrigation technology.
Most Denver-area irrigation systems should be activated between mid-April and early May, depending on weather conditions. Starting too early risks freeze damage to pressurized components, while starting too late can stress new-season turf growth. JLS monitors weather forecasts and schedules activations when the risk of sustained hard freezes has passed for your specific area.
Commercial irrigation systems should be inspected at least monthly during the watering season, with more frequent checks during peak summer heat. Our maintenance clients receive weekly zone-by-zone inspections as part of their service agreement. Between inspections, smart controllers with flow sensors can alert us to problems like broken heads or mainline leaks in real time.
