What is the minimum normal distribution pressure that must be maintained according to TCEQ standards?

The minimum normal distribution pressure that must be maintained according to TCEQ standards is 35 psi. This requirement is crucial for ensuring that the water distribution system can effectively deliver water to all consumers while also preventing issues such as stagnation and contamination. Maintaining a pressure of at least 35 psi helps ensure sufficient flow rates and pressure for service connections, reducing the likelihood of backflow incidents that could introduce contaminants into the system.

This standard is established to safeguard public health and ensure system reliability, particularly during peak usage times or in case of emergencies. Having adequate pressure also protects the integrity of the system, preventing potential damage to the piping and maintaining effective firefighting capabilities.
