The Water Treatment Plant filter backwash water and the Grapevine Municipal Golf
Course wastewater is collected at the WTP Lift Station and then pumped east to the
Hilton Lift Station. The proposed development of the 53+ acre tract (Cumberland Fund)
east of the DFW Hilton on SH 26 includes a large lift station within its boundaries.
This proposed lift station location will allow the wastewater collected at the water plant
from the backwash filters and the golf course to be served by a gravity line. This gravity
line will allow the City to remove the lift station at the plant and reduce the length of force
main in the City by approximately 2,000 LF.

The contract proposal addresses the design of the new gravity line to replace the old
WTP force main.
Staff recommends approval.
