Quick Answer
Existing cisterns can be effectively used for seepage collection, as they are designed to store and conserve water. The structure's existing shape and depth can help to collect and channel rainwater runoff, reducing the need for additional infrastructure.
Assessing Cistern Conditions
Before repurposing a cistern for seepage collection, it’s essential to inspect the structure’s condition. Check for any damage, cracks, or signs of water damage. A cistern with a compromised integrity may not be suitable for water collection. Ensure the cistern’s walls and floor are strong and intact, and the lid or cover is secure. Regular inspection is also necessary to maintain the cistern’s condition and prevent potential issues.
Designing the Collection System
Design a simple and efficient seepage collection system to maximize water yield. This can include installing a network of gutters and downspouts to direct rainwater runoff into the cistern. Consider installing a first flush device to remove debris and contaminants from the initial flow of water, ensuring cleaner water enters the cistern. The cistern’s capacity and flow rate should be assessed to determine the required collection and storage system design. For example, a cistern with a capacity of 5,000 gallons would require a collection system capable of handling around 1-2 gallons per minute.
Maintenance and Upkeep
Regular maintenance is crucial to ensure the effective operation of the cistern and seepage collection system. Inspect the gutters and downspouts regularly to ensure they are clear of debris and functioning correctly. Also, check the cistern’s lid or cover to ensure it is secure and not damaged. Regularly test the water quality to ensure it is safe for use. Additionally, consider implementing a routine cleaning schedule to maintain the cistern’s condition and prevent the growth of algae or other microorganisms.
