Water wells play an important role in both developed and developing countries. Water wells provide water for people and animals to drink. Additionally, it allows for irrigation of farms and gardens and provides a source for hygienic cleaning. Given the important role that a water well can provide for a community or a home, owners must maintain. That way, they continue to provide a fresh reliable water source for many years to come. Read on to learn how you can ensure that you have a safe and clean well.
Protect The Opening
Protecting the opening is perhaps the most obvious way to keep the water well safe and clean for human consumption. Contractors builds modern wells with a cap that fits on top of the wellhead and secures the well opening. Owners should inspect the well-cap regularly for cracks or any other damage. Damage may lead to corrosion, thus leaving the wellhead vulnerable and exposed.
Water well in a developing country might not fulfill modern specifications. In these situations, the well needs a concrete wall surrounding it that also allows for drainage. This helps prevent unclean surface water from flowing into the well. Additionally, it acts as an extra barrier to prevent any people or animals from falling in and harming themselves.
Modern wells avoid sediment through the placement of the water pump. The contractor places water pumps about 25 feet above the bottom of the well. This placement avoids the pump drawing sediment into the water. Additionally, they install well screens to also help filter out the sediment. The well screens act as a barrier that allows water to pass through while preventing sediment from entering the well.
In wells in a developing country without the advantage of modern technology, the sediment must be removed by the digger. Once the digger removes all the loose sediment, they need to add a layer of gravel or rocks. The gravel holds the soil down and prevents it from mixing with the water. Additionally, it will also help prevent the bucket from stirring up silt since it cannot penetrate through the rocks.
Treat The Well And Water
Due to the way modern wells are treated, there is no need to have to physically clean the inside of the well to prevent bacterial or fungus growth. Water is filtered and treated through the mechanics of the well and with regular maintenance and testing, most, if not all, problems can be avoided.
In wells in developing countries where they might not be connected to a filtration system, the inside of the well needs to be regularly cleaned and disinfected. The sides of the well should be scrubbed clean with a chlorine solution that kills bacteria and fungus. Additionally, chlorine should be added regularly to the water to kill microbes that are harmful to both human and animal consumption.
In both developed and developing countries, vegetation can cause a problem for wells. If vegetation manages to get into the water, when the vegetation decomposes, it can cause harmful bacteria for humans to consume. Additionally, the root system of vegetation, especially trees or bushes, can break the side of the well and cause the well to collapse into itself thus rendering the well inoperable.
Animals And Chemicals
Although a person may install a well to provide a water source for animals, the animals must be kept away from the wells. Besides the danger of an animal falling in or damaging the top/opening of the wells, most animals contain microbes that are not normally found in humans. If ingested, these microbes can seriously injure or cause death. Lastly, animal waste, if introduced into the water, will contaminate the water and make it unsafe for consumption.
Many people use their wells for agricultural purposes. If chemicals such as pesticides or manure, is normally used in the agricultural process, it is important to store these far away from the well as possible so that you can have a safe and clean well.
