How often does AWWA recommend that 5/8-in. meters be tested?

The American Water Works Association (AWWA) recommends that 5/8-inch meters be tested every 10 years to ensure accurate measurement of water usage. This frequency helps maintain the reliability and integrity of the water distribution system. Regular testing is crucial because over time, meters can become less accurate due to wear and tear, sediment buildup, or other factors that may affect their performance. By adhering to the 10-year testing recommendation, water utilities can ensure that customers are billed fairly based on precise consumption data. This practice also helps in maintaining operational efficiency within the distribution system, promoting better management of water resources.
