At what level must holding tanks be pumped?

The proper level for pumping holding tanks is at 75% capacity. This threshold is critical because waiting until the tank is filled to a higher level may lead to potential overflows or backups, which can pose health and environmental hazards. Pumping at 75% ensures that there is enough available capacity to handle incoming waste and prevents issues that can arise from exceeding the tank’s design limits. Additionally, regular maintenance and pumping can help to extend the life of the holding tank system and maintain its effectiveness in treating waste. Understanding the optimal pumping level is essential for both compliance with regulations and ensuring the proper functioning of wastewater management systems.
