and/or sewer capacity was currently available or would be available in the near term (see
Section 10 for summary of all district contacts).
Appendices A, B, and C provide water distribution and wastewater collection system
layouts for the alternatives considered from Kingsbridge MUD, North Mission Glen
MUD, and On-site, respectively. Water distribution layouts are shown only for the Onsite
option and connection to Kingsbridge MUD. North Mission Glen is currently
evaluating their water supply system and will not be able to assess their surplus water
capacity until completion of their study. Wastewater collection systems are shown for all
three options.
The wastewater collection schemes for the On-site, Kings bridge MUD and North Mission
Glen MUD options are very similar with 12-inch gravity trunk sewer lines being located
on Richmond-Gaines Road and Boss-Gaston Road and 8-inch gravity sewer lines being
used throughout the residential areas. Three lift/pump stations are required to provide
service to the total planning area because of the size of the planning area, the limitations
on the depths of gravity sanitary sewer construction and the potential for construction in
wet sand conditions. Under the On-site scenario, one of the three stations would be
constructed at the site of the wastewater treatment plant facility.
Under the Kingsbridge MUD and North Mission Glen MUD scenarios, the wastewater
from the Four Comers area will be collected into a single pump station to be located
adjacent to Old Richmond Road south of Boss-Gaston Road. From this pump station,
wastewater will be pumped via force main to an existing 12-inch gravity sanitary sewer
located at the intersection of Bissonnet Road and Richmond-Gaines Road (Kingsbridge
MUD scenario) or to the North Mission Glen MUD wastewater treatment plant located
on Keegans Bayou, north of the Four Corners area (North Mission Glen scenario).
For the On-site scenario, a wastewater treatment plant site is tentatively located along Old
Richmond Road near the southern limits of the planning area and discharges to Red
Gully. No specific tract of land has been identified at this time for the treatment plant site.
