Smart Irrigation Systems

Why Irrigation Matters in Nairobi

Nairobi's bimodal rainfall pattern means that for 4-5 months of the year, gardens receive little or no significant rain. During the January-February dry season and the June-September long dry season, gardens without adequate irrigation quickly show stress — lawns turn brown, plants wilt, and established trees begin to suffer. A well-designed irrigation system removes the dependence on manual watering, ensures every plant receives the exact amount of water it needs, and can reduce water usage by up to 60% compared to hosepipe watering.

At Green Boma, we design, supply, and install a full range of irrigation solutions — from simple drip systems for small gardens to fully automated smart irrigation networks for large estates and commercial properties.

Types of Irrigation Systems We Install

Drip Irrigation Systems

Drip irrigation delivers water directly to the root zone of each plant through a network of small-diameter pipes and emitters. It is the most water-efficient irrigation method available and ideal for flower beds, vegetable gardens, newly planted trees, and any area where water needs to be delivered precisely and economically. Drip systems can be connected to a timer for automated operation.

Pop-Up Sprinkler Systems

Pop-up sprinkler systems are the gold standard for lawn irrigation. Sprinkler heads are installed flush with the lawn surface and pop up automatically during watering cycles, delivering an even coverage of water across the lawn before retracting. We design sprinkler layouts with overlapping coverage zones to ensure no part of the lawn is missed.

Micro-Sprinkler & Spinner Systems

Micro-sprinklers are a mid-point between drip and full sprinkler systems, providing a broader spray pattern suited to ground cover plants, herbaceous borders, and vegetable plots. They are effective where drip emitters provide too little coverage but full sprinklers would be overpowered.

Automated Smart Irrigation

Our smart irrigation systems integrate rain sensors, soil moisture sensors, weather data inputs, and smartphone-controlled timers to deliver precisely the right amount of water at exactly the right time. Smart systems can be programmed remotely via a mobile app, automatically pause during rainfall, and significantly reduce overwatering.

Rainwater Harvesting Integration

We design irrigation systems that can be fed from rainwater harvesting tanks, reducing dependence on mains water supply. This is particularly valuable for properties on restricted water supply or those pursuing green building standards.

Borehole & Water Tank Integration

For properties with borehole water sources or large tanks, we design pumping and distribution systems that make efficient use of available water resources, including pressure management, filtration, and automated pump controls.

Irrigation System Design

A correctly designed irrigation system starts with a hydraulic calculation — understanding the available water pressure and flow rate, the total area to be irrigated, the soil type and absorption rate, and the water requirements of the specific plants being grown. Green Boma's irrigation designers carry out full system designs before installation begins, ensuring every zone is correctly sized and every emitter delivers the specified flow rate.

Irrigation Maintenance & Service Contracts

Like any mechanical system, irrigation networks require periodic servicing. We offer annual service contracts from KES 5,000 per year covering inspection of all components, filter cleaning, emitter checks, timer programming, and pressure testing. For large commercial systems, we offer quarterly service contracts.
