EMERGENCY PROCEDURESEMERGENCY PROCEDURES Emergency Procedures for Power Outage and Bypass Pumping

Monarch Landings Sanitary Lift Station

 

Location: Corporate Drive

Sub: Monarch Landing Senior Village

 

Power Outage to lift station:

Once outage is detected, standby generator will provide 25 KVA of power, supplied by Olympian generator located on site.  Generator if fueled by natural gas.

Power outage can be monitored remotely by city Wastewater S.C.A.D.A. system located on City’s Citrix website.

 

Bypass Pumping:

If emergency generator is unable to provide power to the station.  Then bypass pumping becomes 2nd options. 

 

Then following procedure is to take place:

Make sure all employees have their PPE on them (Hard hat, safety glasses, safety boots, safety vest, gloves, and confine space gear, to perform the following task.

 

Quickly inspect 4” pump for the following items. 4” gaskets on connecting side of the suction and discharge side of hoses.  4” pump has be topped off with fuel. No sign of any leaks regarding fuel, oil, or antifreeze.

Make sure pump is primed before starting the pump at the station.

Open both lift station gates, and back the pump inside the fence area.

Position 4” pump so towing tongue of pump is facing EAST  Discharge would be facing NORTH.  Suction would be facing WEST

Place both pumps in the off position inside the control cabinet.

Pull all floats, level transducer out of the wet well.  Make sure floats are not tilted.

Put three 4” rigid suction hoses into the wet well just above the pumps. (Make sure you DO NOT drop hose onto pump head or electric head cord.)

Make sure all quick couplings are latched and secured to prevent accidental disconnect from the hoses.  If needed use duct tape or wire-ties to prevent accidental disconnect.

Connect one 4” discharge hose and laid it to the manhole just to the north of the station.

(Basin N01-056 manhole is painted red) Just outside of the northeast fence line.

Start 4” pump to pump down wet well.  Continue to monitor wet well levels and slow pump down to prevent lose of suction.

When power is restored, pump wet well level down as far as you can go.

Turn off your 4” bypass pump.

Manual run both pumps to insure everything is fine and running normal with the station prior to removing bypass setup.

Place floats and level transducer back into wet well

Test run station under load and make sure station is pumping and pumps are alternating.

Remove all bypass equipment.

Contact Field Supervisor and Springbrook once everything is running normal.

 

Using Vactor to remove sanitary wastewater from wet well

When both above procedures are not an option then use Vactors #779 & #777:

 

Make sure all employees have their PPE on them (Hard hat, safety glasses, safety boots, safety vest, and gloves to perform the following task.

Open lift station gates as wide as possible.

Open doors and secure them in the locked position.

 Pull all floats, level transducer out of the wet well.  Make sure floats are not tilted; they will active alarms at the station and Springbrook.

Pull Vactor into station with front of truck entering driveway first.

Position Vactor suction hose over wet well doors.

Connect about 3 to 4 8” tubes together. (USE CLAMPS TO CONNECT TUBES TOGETHER, PLUS USE DUCT TAPE TO SECURE CLAMPS FROM COMING APART)

As water level drops you’ll need to add more tubes. Please follow same instruction as G (see above) when installing addition tubes.

Engage Vactor to start vac.ing water from wetwell (Stay above water approximately 3 inches to prevent suction from clogging with water.  This will stop removing water from wetwell.)

Once Vactor tank is full you’ll need to dump water into sanitary manhole which will not drain back into wet well. (Basin N01-056 manhole is painted red) Just outside of the northeast fence line.

Once level is normal and station is back on line, place floats, level transducer back into wet well, monitor station for correct operation.

Contact Springbrook and Field Supervisor.
