Procedure function
1. Concentration of hazardous or toxic substances in backwash and any waste effluent no greater than feed water.
2   . Direct handling of hazardous or toxic substances
3.  No special tools required for routine service supplied with system
4. Pump ON/OFF operating state controlled through communication interface
5.  Fault reset provided through the communication interface
6. Total gallons processed calculated and available through the communication interface, but the cost extra

7.  Differential pressure across each system stage available through the communication interface

8. System operating state / mode available through the communication interface

9. Backflow prevention valve in processed water outlet

10. Detect and report fault due to feed water: TDS > 1000 ppm; turbidity > 100 NTU, temperature < 5 C; temperature > 45 C; catastrophic leaks; conditions which indicate a possible failure to remove fecal coliforms to the level specified

11. Minimum useable life of system: 7 years
