Water Storage

Water storage
Store drinking water for circumstances in which the water supply may be polluted or disrupted. If water comes directly from a good, pretreated source, then no additional purification is needed otherwise, pretreat water before use. Store water in sturdy, leakproof, breakage-resistant containers. Consider using plastic bottles commonly used for juices and soft drinks. Keep water containers away from heat sources and direct sunlight.

Water versus Food
You can last on average about two to three weeks without food, but only about three days without water. (This is a rough estimate there are a lot of influencing factors that would increase or decrease these numbers.)

Often Neglected
It is estimated that in Kirinyaga county, no more than 10% of families have more than two weeks of water storage in their home. Water is one of the most important storage items, yet for whatever reason is often neglected.

Water storage consumes a great deal of space. A typical 55 gallon drum is about two feet wide by three feet tall. Not everybody has an unfinished basement or garage with sufficient space to store multiple barrels or other containers

Water may be stored in a variety of containers. Some containers and storage locations adversely affect the water supply by leeching chemicals into the water or affecting the taste. Additionally, some containers may degrade or disintegrate with time, leaking your water into the surrounding area.

It is hard to know with accuracy the history of the water you are drinking. Where has it been, what has it been treated with, and how long has it been sitting still? What temperatures has it been subjected to, how much sunlight exposure has it had, and for how long? Poor conditions such as those listed above create opportunities for unwanted bacteria and organisms to grow in your water supply.

There are a variety of suggestions on how best to purify water, water service providers do their best to ensure your tap water is as safe as possible. KIRIWASCO uses water treatment procedures that are approved by KEBS and other relevant bodies.

Water should only be stored in food-grade plastic or other material that is created specifically for long term storage of liquids intended for consumption. It is important that you be careful what you store your water in, as some containers can leech, crack, degrade, or otherwise cause problems with your water. Before storing your water, it is usually a good idea to wash and sanitize the container. This can be done by mixing 1 teaspoon (5 ml) of liquid household chlorine bleach to one quart (1 liter) of water. Do not use bleach that has scents, additives, or thickeners.

It is not necessary to treat water that is already chlorinated before storing it. Many water service providers chlorinate their water supply, so if that’s the case with your wsp, any water from your tap is safe and ready to be stored in an appropriate container without any extra action on your part. Exposure to light plays a large part in the development of bacteria; where possible, it’s best to store your water in a cool, dark place (same goes for your food).
