2. Wastewater Capital Improvement <strong>Plan</strong><br />
The wastewater plan is based on providing facilities to meet the peak monthly average<br />
daily flow of 61 MGD, which is the projected <strong>2030</strong> wastewater dem<strong>and</strong> for Horry<br />
County. The City of North Myrtle Beach will be provided wholesale service from<br />
GSWSA’s Vereen plant to supplement the capacity from the two city owned facilities.<br />
GSWSA <strong>and</strong> North Myrtle Beach have a wholesale contract in place for GSWSA to<br />
provide capacity to meet the city’s future capacity requirements. Should GSWSA reach<br />
an agreement with the City of North Myrtle Beach to acquire the City’s two wastewater<br />
plants, it will not affect the wastewater CIP since the plants are not projected to be<br />
exp<strong>and</strong>ed regardless of ownership.<br />
The plan is based on GSWSA continuing to provide wholesale <strong>and</strong> retail wastewater<br />
services. Projected wholesale wastewater customers are:<br />
• City of Myrtle Beach<br />
• City of North Myrtle Beach<br />
• City of Conway<br />
• Little River <strong>Water</strong> <strong>and</strong> <strong>Sewer</strong>age Company<br />
• Georgetown County <strong>Water</strong> <strong>and</strong> <strong>Sewer</strong> District<br />
• Tabor City<br />
Since GSWSA will be providing wholesale service in these areas, capital improvements<br />
internal to these utilities are not considered in the wastewater plan. If any utilities decide<br />
to merge with GSWSA, the plan will be revised accordingly. City of Marion wastewater<br />
system merged with GSWSA in May 2010. The facilities have excess capacity expected<br />
to be adequate to accommodate growth to <strong>2030</strong>. The system has significant inflow which<br />
will be reduced through renewal <strong>and</strong> replacement projects.<br />
a. Wastewater <strong>Plan</strong>ts<br />
Future wastewater plant improvements will involve consolidation or elimination of some<br />
facilities, construction of a new treatment plant, <strong>and</strong> upgrades <strong>and</strong> expansions of all other<br />
plants.<br />
(1) Bucksport/Tip Top Regional WWTP<br />
Bucksport/Tip Top Regional WWTP will be a new advanced secondary treatment<br />
process plant with nitrogen removal <strong>and</strong> filtration to assure the high levels of treatment<br />
needed for l<strong>and</strong> application. The <strong>2030</strong> capacity is expected to be 5 MGD. Flows to this<br />
facility will come from a combination of diversions from Carolina Forest, the south<br />
str<strong>and</strong>, <strong>and</strong> the areas of Conway <strong>and</strong> western Horry County. <strong>Plan</strong>ts now serving these<br />
areas will not be exp<strong>and</strong>able to h<strong>and</strong>le all the increasing flows because of their restricted<br />
discharge limits. The l<strong>and</strong> application system at Tip Top provides an excellent disposal<br />
site which does not discharge into or increase any loadings to the rivers. A new<br />
transmission force main will be constructed to send flows from Carolina Forest, Conway<br />
<strong>and</strong> western Horry County to the Bucksport WWTP.<br />
