Title

16 Emergency Recycled Water Bypass Primary & Secondary Systems

Treatment systems at the WWTP use Recycled Water for process and equipment water. In general, this SOP simply involves connecting rubber hoses between an Industrial Water source and a Recycled Water header. The Industrial Water and Recycled Water supply valves are manipulated to direct Industrial Water through the rubber hose and into the Recycled Water piping system. 

Primary and Secondary Systems that require bypass activities include the following:
1.     Blower Cooling Water
2.     Sludge Pump Seal Water.    
SOP Identification Number
SOP Identification Number:
1603_Emergency Recycled Water Bypass Primary & Secondary Systems
Purpose and scope
Purpose and scope:

If for some reason the Distribution Pump Station is offline (pump failure, maintenance, etc.) the Emergency Back-Up Pump can be used to pump Recycled Water to the WWTP systems.

Definitions
Definitions:

DSPS:  Distribution System Pump Station

Cautions
Cautions:
  • Ensure that the correct breaker switch is flipped.
  • Water must be available for distribution from the Reservoir.
  • Emergency Back-Up Pump must be operational and online.
  • Recycled Water piping is easily identified in the field since it is painted purple.
Potential Interferences
Potential Interferences:
  • The Recycled Water Emergency Backup Pump must be operational and online in order for this Bypass SOP to work.
Personnel Qualifications
Personnel Qualifications:


Operator I, knowledge of primary treatment process and SCADA controls.

Quality Control/Quality Assurance Activities for the Procedure
Quality Control/Quality Assurance Activities for the Procedure:

Please note: It is assumed that the DSPS is already offline before this SOP begins. 

Steps 1 – 5 can be performed in any order, but all must be complete before starting Step 6.

Procedure
Procedure:
1.     Bypass Industrial Water at Blower System. 
a.     Locate a rubber hose and two female to female hose couplings.
b.     Locate the Industrial Water supply pipe and hose bibon the northwest wall of the Blower Room.
c.     Locate the Recycled Water hose bib at the Blower skid. 
d.     Connect the rubber hose to the Industrial Water source hose bib and to the Recycled Water hose bib using the couplings. 
e.     Open the Industrial Water isolation valve. Allow the rubber hose to fill with Industrial Water.
f.      Open the Recycled Water hose bib valve.
g.     Close the Recycled Water isolation valve. The Blower Cooling Water System is now running on Industrial Water.

 
2.     Bypass Industrial Water at Sludge Pump Room. 
a.     Locate a rubber hose and two female to female hose couplings.
b.     Locate the Recycled Water supply pipeand hose bib on the northwest wall of the Sludge Pump Room.
c.     Locate the Industrial Water hose bib at Gallery #6. 
d.     Connect the rubber hose to the Industrial Water Source hose bib and to the Recycled Water hose bib using the couplings.  
e.     Open the Industrial Water isolation valve. Allow the rubber hose to fill with Industrial Water.
f.      Open the Recycled Water Hose bib valve.
g.     Use a ladder to access and close the Recycled Water isolation valve {tag no. 1603VL6287} which is located approximately 9 feet from the floor and is on the northwest wall of the Sludge Pump Room. The Sludge Pumps Seal Water System is now running on Industrial Water.   
 
3.     Bypass Industrial Water at Sludge Pump Room. 
a.     Locate and close the Recycle Water isolation valve to the Primary and Secondary Treatment Utilities, on the southwest wall of the Sludge Pump Room.
