It is advisable to keep rainwater away from septic tanks and foul water treatment plants. Rainwater can disrupt the biological process within these systems. As the future trend is shifting towards treatment plants, it is important to divert rainwater from foul water discharge. Connecting rainwater to septic tanks can cause flooding during heavy rainfall. It is recommended to size tanks properly and consider expected foul water flows and storm events. Keeping rainwater and stormwater separate from foul water discharge is good practice to avoid potential issues.
