1. Rain Test is fed by rinse pump to Gantry wash unit.

2. Water from the test accumulates in the wash bay trench.

3. A manual controlled ball valve is closed using a T-Bar.

4. Water from the trench is diverted to the rain test sump pit.

5. The rain test sump pump will pump water from the sump thorough the bag filter and into the 850 gallon rinse water reclaim tank. Oxygen will be added on a continuous basis to the rain test reclaim tank.

6. The reclaim tank will feed to the rinse water pump on the pump skid.

7. A fresh water makeup line will feed the loop as necessary based on a 20 gallons/minute max flow rate from the rinse pump.

7. Controls will keep the pumps working to recirculate water in the loop as long as the rain test is in operation.

**8. Float control valves in the sump pit and the rain test reclaim tank will be utilized to balance incoming and outgoing flow for the loop.
