Water Supply and Sanitation

The Nipple Drinker Revolution

Traditional farms use concrete troughs or “basins” for water. In an African piggery, these are a disaster for two reasons:

1. Waste: Pigs love to play with water. They will splash half of it onto the floor, turning your “Pig Fortress” into a swamp and ruining your drainage.

2. Contamination: Pigs will often poop or step into their water troughs. This spreads worms and bacteria like Salmonella across the whole pen.

The Solution: Automatic Nipple Drinkers.

These are stainless steel valves that screw into a water pipe. The pig must bite or push the nipple to get water.

• The Benefit: The water is always fresh and clean inside the pipe. It stays cool, and there is almost zero waste.

• The Setup: You need a header tank (like a 500-liter plastic tank) placed higher than the pens to provide “gravity flow.”

Water Quality: If You Won’t Drink It, Don’t Give It to the Pig

In many rural areas, water comes from boreholes, rivers, or dams.

• Borehole Water: Often contains high levels of salt or “hardness.” Very salty water can actually poison pigs or make them refuse to drink.

• River/Dam Water: This is high-risk. If a farm upstream has sick pigs and their waste runs into the river, your pigs will get infected.

• The Agripreneur Fix: If you use surface water (rivers/dams), you must treat it. Using simple chlorine (like WaterGuard or Jik) in your header tank can kill 99% of the germs that cause diarrhea.

Temperature Matters: The Cool Water Secret

Pigs hate warm water. If your water pipes are exposed to the direct sun on top of the roof, the water inside will get hot. A pig that is already struggling with the heat will refuse to drink hot water, leading to heatstress.

• The Fix: Bury your delivery pipes at least 1 foot underground or shade your header tank with a simple thatch roof. Keeping water cool encourages pigs to drink more, which keeps their internal “engine” running and growing.

The Sanitation Cycle: Keeping the Source Clean

Your water system can unknowingly spread disease if not maintained.

1. Tank Cleaning: Every month, climb up and check your header tank. You will often find a layer of green algae or “sludge” at the bottom. Scrub it out!

2. Biofilm Removal: Over time, a “slime” (biofilm) grows inside the pipes. Once a year, flush your system with a strong disinfectant solution to clear the “arteries” of your farm.

3. The Drainage Link: Ensure your drinkers are placed directly over the drainage hole of your sloped floor. Any small drips should go straight out of the pen, keeping the sleeping area dry.

Water Requirements by Age

As an expert agripreneur, you must plan your tank capacity based on your herd size. Use this table to ensure you don’t run dry:

Case Study: The Stunted Pigs of Embu

Farmer Kamau noticed his pigs were taking 8 months to reach 60kg. He was buying the best feed, but the pigs looked “stunted.” A vet visited and noticed Kamau was using a single trough for 10 pigs. The “bully” pigs would drink their fill and then stand in the trough, preventing the smaller pigs from drinking. The smaller pigs were essentially “dehydrated.” Kamau installed three Nipple Drinkers at different heights. Within two months, the growth rate doubled. He realized it wasn’t a “feed problem” – it was a “water access” problem.

Installation Tips for the Handy Farmer

• Height is Key: Mount the drinker about 2 inches (5cm) above the shoulder height of the pig. As the pigs grow, you may need to have “adjustable” points or multiple nipples at different heights.

• Pressure Check: If the water sprays out too hard like a fire hose, the pig will be scared to drink. If it just drips, the pig will get frustrated. Aim for a steady, calm flow.

• Angle: Mount the nipple at a 45-degree angle pointing downwards. This makes it easiest for the pig to “mouth” the valve.

Important things to keep in mind:

• Water is the cheapest feed you have. Don’t be stingy with it.

• A dry tank is an emergency. If pigs go without water for 24 hours and then suddenly drink a huge amount, they can suffer from “Salt Poisoning” (Water Deprivation Syndrome), which can kill them.

• Check the Click: Every morning, walk through your pens and flick each nipple with your finger. If it doesn’t “click” and release water, fix it immediately.
