How many readings should be recorded during the pumping test?

During a pumping test, it is essential to obtain multiple readings to accurately assess the performance of the water supply system and to ensure that the results are representative. Recording six readings allows for a thorough analysis of the system's behavior over time, capturing any variations that may occur during the test period. This number of readings provides a balanced approach, ensuring that data is not too sparse while also avoiding excessive complexity in data management.

Monitoring six separate points in time typically helps in identifying trends and establishing a comprehensive understanding of how the system performs under specific conditions. This can be critical for evaluating capacity, efficiency, and any operational issues that might arise during the test. Thus, selecting six readings strikes a balance between thoroughness and simplicity, making it the recommended practice in this scenario.
