What is a Lawn Irrigation System?

A lawn irrigation system is a setup designed to distribute water evenly across a lawn. It automates the watering process to ensure that your grass gets the right amount of water, at the right time, and in the right areas. This not only saves time and labor but also conserves water compared to traditional manual watering.

There are various types of irrigation systems, from basic hose-end sprinklers to sophisticated underground setups with smart controllers. The most used systems in Kenya are pop-up sprinkler systems, movable garden sprinklers, and rotary sprinkler systems.

Specifications of Lawn Irrigation System

Understanding the technical specifications is crucial when planning an efficient irrigation setup. Here are key specs you need to consider:

Flow Rate

Measured in liters per minute (L/min), this refers to how much water your system can deliver. A typical home irrigation system requires 10–20 L/min, depending on the lawn size.

Pressure Rating

Irrigation systems usually need water pressure between 2–4 bars (30–60 psi). Too low, and your sprinklers won’t pop up; too high, and the nozzles may wear out quickly or burst.

Spray Radius

This is the area a sprinkler head can cover. For example, a pop-up sprinkler may cover a radius of 2 to 5 meters, while rotary sprinklers can reach up to 15 meters or more.

Sprinkler Design

Modern sprinklers are designed to mimic rainfall, minimize runoff, and adjust based on the terrain. Some even rotate for full 360° coverage, while others are fixed for targeted zones.

Lawn Sprinkler Price in Kenya

Lawn Sprinkler Price is around KES 2,500 to KES 5,000 for all sizes from ½ to 1 inch.

Pop-Up Sprinklers and their Features

Pop-up sprinklers are the most popular choice for residential lawns in Kenya. These are embedded underground and rise when activated by water pressure. Once watering is complete, they retract back into the ground, maintaining a clean and uncluttered lawn surface.

Features of Pop-Up Sprinklers

• Adjustable Nozzles: Change spray patterns and distance.
• Durability: Made from UV-resistant materials.
• Low Maintenance: Easy to clean and replace.
• Zone Control: Sprinklers can be divided into zones or stations for customized watering.

Types of Lawn Irrigation Sprinklers

Different lawns require different types of sprinklers. Here are the main options available in the Kenyan market:

a) Fixed Spray Sprinklers

Ideal for small, flat lawns. They spray in a specific pattern: half-circle, quarter-circle, or full-circle.

b) Rotary Sprinklers

Best for medium to large lawns. They rotate and spray water in circular patterns, providing even coverage.

c) Impact Sprinklers

Known for their clicking sound, these are durable and good for larger areas like golf courses or school fields.

d) Oscillating Sprinklers

These move back and forth, spraying a fan-shaped curtain of water. Common for rectangular lawns.

Complete Requirements for Setup of Lawn Irrigation System

To have a functional lawn irrigation, you’ll need:

Water Source: Tap, borehole, or storage tank.

• Pump (if using a borehole or tank): Ensures adequate pressure.
• Main Water Line: PVC or HDPE pipes.
• Sprinkler Heads: Based on coverage needs.
• Valves and Controllers: For automated scheduling and zone control.
• Backflow Preventer: To prevent backflow of water and contamination of your water supply.
• Filtration Unit: Essential for sediment removal especially if using borehole water.
• Fittings and Connectors: Elbows, tees, couplers.
• Timer or Smart Controller: to automatically start and shut off irrigation.
• Trenching Tools: For laying pipes underground.

How Does Lawn Irrigation System Work?

Here’s a simplified overview of how a typical system functions:

1. Timer activates the system at a pre-set time.
2. Mainline valve opens, allowing water flow.
3. Water flows through the pipes to various zones.
4. Sprinklers pop up (if using pop-ups) and distribute water.
5. System runs for a specified duration and shuts off automatically.
6. Sprinklers retract, and the system returns to standby mode.

Smart controllers can even adjust watering based on weather forecasts and soil moisture levels.

What Are the Factors to Consider When Choosing a Lawn Irrigation System?

When choosing an irrigation system for your lawn in Kenya, consider:

• Lawn Size: Larger lawns require rotary or impact sprinklers; smaller lawns may use pop-ups.
• Water Source and Pressure: Borehole water may need filtration; ensure enough pressure.
• Soil Type: Sandy soils drain fast; clay retains water longer.
• Climate: Arid areas may need more frequent watering.
• Budget: Factor in initial cost, installation, and maintenance.
• Automation Needs: Decide between manual, semi-automatic, or smart systems.
• Aesthetic Concerns: Underground systems are more discreet.

Cost of Lawn Irrigation System in Kenya

The cost of installing a lawn irrigation system in Kenya can vary based on location, lawn size, system complexity, and product brand.

Note: Prices may vary depending on supplier and location (Nairobi, Mombasa, Kisumu, etc.).

How to Install a Lawn Irrigation System

While professional installation is ideal, DIY-savvy homeowners can also install basic systems.

Basic Installation Steps:

1. Plan Layout: Draw your lawn and mark sprinkler zones.
2. Purchase Materials: Based on your plan and measurements.
3. Trench the Lawn: Dig channels for the piping network.
4. Lay Pipes: Connect to mainline and zones.
5. Install Sprinklers: Attach heads and place them securely.
6. Install Controller and Valves.
7. Test the System: Check pressure, coverage, and leaks.
8. Backfill Trenches: Cover pipes and re-turf the area.

Precautions When Installing of Lawn Irrigation System

• Before You Dig: Know where electrical and plumbing lines run.
• Use Filtration: Prevent clogging of sprinklers from debris or borehole silt.
• Avoid Excessive irrigation: set controllers or timer to water for 30-40 minutes to prevent overwatering pooling which could damage grass.
• Avoid Overlapping Sprays: Causes overwatering and disease.
• Test Pressure Beforehand: Prevent system damage.
• Use Quality Materials: Low-quality parts lead to frequent repairs.
