Quick Answer
Incorporating a cistern into sustainable living provides the benefits of rainwater harvesting, reduced water bills, and improved water security during droughts and water shortages.
Cistern Sizing: A Crucial Factor in Water Harvesting
When designing a cistern for rainwater harvesting, the size of the cistern is a critical factor to consider. A well-sized cistern can store enough rainwater to supply a household’s needs for an extended period. As a general rule, a cistern should be sized to hold at least 1,000 gallons of water per household member. For example, a family of four would require a 4,000-gallon cistern.
Types of Cisterns: Concrete, Metal, and Plastic
There are various types of cisterns available, each with its own unique characteristics and advantages. Concrete cisterns are a popular choice due to their durability and low maintenance requirements. Metal cisterns, on the other hand, are more suitable for smaller households and are often less expensive than concrete cisterns. Plastic cisterns are a lightweight and affordable option, but may require more frequent replacement due to UV degradation.
Maintenance and Upkeep: Ensuring Cistern Safety and Effectiveness
Regular maintenance is essential to ensure the safety and effectiveness of a cistern. This includes checking for leaks, inspecting the cistern’s liner for damage, and ensuring that the cistern is properly vented to prevent the growth of algae and bacteria. Additionally, cisterns should be cleaned and disinfected regularly to prevent contamination and ensure the quality of the harvested water. By following these maintenance guidelines, households can enjoy the many benefits of rainwater harvesting and sustainable living.
