⏱️ Runtime & Efficiency Tools

Optimization for Existing Systems

While the System Design Calculators and Design Tools help you plan new installations, these tools help you optimize what you already have. Whether you're fine-tuning watering schedules or identifying efficiency improvements, these calculators provide data-driven answers.

💰 Why Runtime Optimization Matters

Most residential irrigation systems waste 30-50% of water due to improper scheduling and poor uniformity. These tools help you:

Save 30-50% on water bills through proper runtime calculations
Improve lawn health with precise water delivery
Identify system problems before they cause damage
Quantify savings from system upgrades
Meet water restrictions while maintaining green lawns

Zone Runtime Calculator

Calculate the number of minutes each zone should run to deliver the perfect amount of water. This tool determines optimal runtime based on your specific sprinkler precipitation rate.

Solves a critical problem: Most people set their timer by guessing - "15 minutes sounds good" - leading to massive overwatering or underwatering. This calculator uses scientific principles to give you the exact runtime needed.

How it works: Determine your sprinkler precipitation rate (how many inches per hour your sprinklers apply):

MP Rotators: ~0.4-0.8 inches/hour
Traditional spray heads: ~1.5 inches/hour
Rotors: ~0.4-0.75 inches/hour
Or measure with catch cup test for exact rate

Pro Tip: Most people overwater by 40% or more! Proper runtime calculation typically reduces water use and costs by 30-50% while improving lawn health.

Water Savings Calculator

Calculate potential water and cost savings from improving your system's Distribution Uniformity (DU). See exactly how much money you'll save by upgrading to more efficient sprinkler heads.

What it calculates:

Water waste reduction - Gallons saved per time period
Cost savings - Real dollar amounts based on your water rates

Catch Cup Test & Sprinkler Audit

Perform a professional catch cup test to measure your system's actual Distribution Uniformity (DU) and precipitation rate. This comprehensive audit tool collects all the technical data needed for smart irrigation controller programming and system optimization.

Waste Calculation - Quantify water losses

Cost Savings - Real dollar amounts

What is Distribution Uniformity (DU)?

DU measures how evenly your system applies water across the irrigated area. Think of it as a grade for your sprinkler system:

85%+ DU = Excellent - Modern MP Rotators, well-maintained systems
75-84% DU = Good - Quality spray heads with proper maintenance
60-74% DU = Fair - Older systems, basic spray heads
Below 60% DU = Poor - Typical old systems, mismatched heads, worn components

Why DU matters:

Poor DU = Some areas get too much water, others too little
To keep dry spots green, you have to overwater everywhere else
Low DU directly translates to wasted water and money
Typical old systems have 50-60% DU (massive waste)
Upgrading to MP Rotators can achieve 75-85% DU

Real Example: Improving DU from 50% to 75% on a typical 5,000 sq ft lawn can save $400-800 per year on water bills. The upgrade pays for itself in 1-3 years!

Use this audit tool to:

Measure actual DU through systematic catch cup testing
Calculate precise precipitation rates for each zone
Collect system parameters for smart controller programming
Document baseline performance for upgrade ROI analysis
Generate professional audit reports for rebate applications
