Storage, Pumps, and Controls for Reuse Water Systems
Storage and pumping decisions often determine whether a reuse system is reliable. The system must collect water, store it safely, deliver it at the needed flow and pressure, and manage overflow or low water conditions.
Important design items
- Usable tank volume, not just total tank volume.
- Drawdown time based on demand and pump operation.
- Pump duty point, total dynamic head, and backup needs.
- Float switches, level sensors, pressure controls, and alarms.
- Overflow routing that protects the site during large events.
