Cleaning Water Storage Tank Kenya – Essential Guide for Safe Water
Introduction
Let’s face it—when was the last time you cleaned your water storage tank? If you’re like most Kenyans, probably not recently. Yet this often-ignored task could be the reason your water smells off or makes people in your home sick.
In Kenya, where water can come from boreholes, rivers, or rain, your storage tank is your last line of defense. And like any defense system, it needs maintenance.
Importance of Cleaning Water Storage Tanks
Dirty tanks are silent hazards. Sediment, algae, bacteria—even insects and rodents—can make their way inside, especially when tanks are left uncovered or untouched for months.
Not only does this compromise water quality, but it also damages filters and shortens the life of your purifier system.
Common Types of Water Tanks in Kenya
Plastic Tanks (e.g., Roto, Jojo): Common in homes and small businesses.
Concrete Tanks: Mostly for large-scale use, often underground.
Underground Tanks: Cooler and less exposed but harder to clean.
Overhead Tanks: Easy to access, but exposed to dirt and sunlight.
Signs Your Tank Needs Cleaning
Bad Smell or Taste: Could be bacterial activity or algae.
Sediment Buildup: Especially common with borehole and river water.
Discoloration: Brown or greenish water is a big red flag.
Increased Illness: Stomach upsets, skin irritation, and more.
How Often Should You Clean Your Water Tank?
Experts recommend every 6 months, but you may need more frequent cleaning if:
You use untreated water.
The tank is exposed to dust or animals.
Rainwater harvesting is your primary source.
DIY Tank Cleaning – Step-by-Step Process
1. Safety First: Wear gloves, goggles, and non-slip shoes.
2. Gather Tools: Use brushes, scrapers, buckets, and a hose.
3. Drain the Tank: Open the outlet valve completely.
4. Scrub: Use a stiff brush to clean the sides and bottom.
5. Disinfect: Add chlorine (or preferred cleaner) and let it sit.
6. Rinse Thoroughly: Remove all cleaning agents before refilling.
Pro tip: If the tank is too large or you feel unsafe, call a pro.
Best Cleaning Agents and Disinfectants
Chlorine Bleach (Sodium Hypochlorite): Most effective.
Hydrogen Peroxide: Less harsh and environmentally friendly.
White Vinegar: Natural but less effective for large tanks.
Commercial Tank Cleaners: Available at water equipment shops.
