Off-Grid Water Planning for Farms in Kenya: Reliable Supply Without Electricity

In Kenya’s growing rural zones especially in areas like Kajiado, Laikipia, Kitui, and Taita Taveta farmers are increasingly opting for off-grid water systems. Whether for livestock, greenhouses, or domestic use, having a self-sufficient water supply is essential for productivity and independence.

This guide offers a practical breakdown on how to design a reliable, low-maintenance water plan without relying on KPLC or fuel-based systems.

1. Estimating Your Farm’s Water Requirements

Start by determining your daily water demand based on your activities:

Water Use Estimated Daily Need
1 dairy cow 40–60 litres
1-acre drip irrigation 1,000–1,500 litres
Family of 5 250–400 litres

If your farm includes irrigation and livestock, you could require 5,000–10,000 litres per day. Get more help from this guide:

2. Choosing Suitable Storage Tanks

Water tanks are the heart of any off-grid system. Select durable, high-capacity tanks that can withstand Kenya’s varying climate.

Tank options:

  • Polyethylene tanks (e.g. Kentank): Lightweight, UV-stabilized, ideal for farms
  • IBC tanks: Good for portable or segmented storage
  • Concrete tanks: Long-term underground storage for large volumes

3. Blend Multiple Water Sources for Security

Don’t rely on just one source. Combine these for drought resilience:

  • Borehole or shallow well
  • Rainwater harvesting during wet seasons
  • Seasonal streams or pans for livestock

Use connectors, valves, and float switches to manage flow across sources:

4. Solar-Powered Pumps: The Off-Grid Gold Standard

Solar pumps eliminate fuel dependency. Ideal for remote farms, they’re quiet, scalable, and cost-effective in the long run.

Setup tips:

  • Oversize panels to maintain pressure on cloudy days
  • Use a float switch to avoid tank overflow
  • Consider a petrol pump as emergency backup

5. Gravity-Fed Distribution Systems

Use gravity to move water from elevated tanks to your taps or drip lines.

Requirements:

  • Tank height of 3–6 meters
  • 1–2 inch piping for sufficient flow
  • Shutoff valves and overflow outlets

6. Rainwater Harvesting: Low-Cost, High Return

Set up gutter systems on roofs and greenhouses with first-flush filters. Store water in large plastic or underground tanks.

7. Smart Automation with Float Switches

Reduce human error by automating pump operations:

  • Tank refills
  • Overflow protection
  • Alternating source selection (e.g., rain vs. borehole)

8. Maintenance Tips for Longevity

Avoid breakdowns and contamination by:

  • Cleaning tanks at least once a year
  • Screening all inlets and overflows
  • Regularly washing solar panels and roof gutters
