Plans for the lift station and the full length of force main (FM) shall both be submitted in order

to do an official review of either set of plans.

❑ A Lift Station Report needs to be submitted as described in the Utility Criteria Manual for a

review of the force main (FM) to be done. Include peak wet and dry weather design flows in

each pipe shall include quantity in gallons per minute, depth of flow in inches, velocity in

feet per second (min 3ft/sec) and “n” factor of 0.013 per TCEQ 217.

❑ The manhole where the force main discharges into the gravity sewer needs to be a polymer

concrete manhole with the entrance and exit elevations the same, to minimize turbulence at

the discharge. Show the exiting elevation and size of the pipe.

❑ Wastewater air release valve or air vacuum valves shall be installed at the high point in

all force mains. See the enclosed example detail.

❑ Station numbers at all proposed connections to existing or proposed wastewater mains.
