2030 Plan - Grand Strand Water and Sewer Authority

(7) Bucksport
The Bucksport WWTP plant is permitted to receive up to 200,000 GPD and uses a lagoon
treatment system to produce secondary effluent for discharge to the Tip Top tree farm
land application site. A limited amount of the treated effluent can be discharged to the
nearby Waccamaw River. The by-product sludge is treated in the lagoons and is stored
until it is removed for disposal at GSWSA’s land application sites. The plant is located
on the southern end of the Bucksport community and receives wastewater from the
Bucksport community as well as surrounding areas.
(8) Longs
The Longs WWTP is permitted to receive up to 200,000 GPD and uses a lagoon
treatment system to produce a secondary effluent that is permitted for discharge to the
Waccamaw River. Since 2008, the treated effluent has been diverted to the Vereen
WWTP. The by-product sludge is treated in the lagoons and is stored until it is removed
for disposal at GSWSA’s land application sites. The plant is located in the Longs
community and receives wastewater from the Longs community as well as surrounding
areas.
(9) Green Sea-Floyds
The Green Sea-Floyds WWTP is permitted to treat up to 10,800 GPD and uses a lagoon
treatment system to produce secondary effluent for discharge to a land application site.
The by-product sludge is treated in the lagoons and is stored until it is removed for
disposal at GSWSA’s land application sites. The plant is located off Highway 9 just east
of the Green Sea-Floyds High School.
b. Collection and Transmission
GSWSA owns 1,448 miles of combined gravity sewer and force mains. The gravity
sewer is primarily a conventional gravity system except the small diameter sewers with
settling tanks serving Longs, Bucksport, and Burgess Communities. Gravity sewer flows
to pumping stations connected through 361 miles of pressure transmission mains to
treatment plants.
Pumping stations are grouped as follows:
Residential - 3,000 pumping stations that serve only one or two customers.
Subdivision - 450 subdivision pump stations each having a 5 or 6 foot wet well, two
pumps, and associated gravity sewer generally designed to serve a small area consisting
of one subdivision. A few serve more than one subdivision, serve adjacent properties, or
serve only part of a larger subdivision.
