Construction is estimated to cost$2.9 million'in 2007 dollars. This section describes the findings of the Task Force prior to the community design workshop in June of 2008. Concept B serves the same properties via a new line to the west. Construction is estimated to cost$ 2.5 million'in 2007 dollars. Neither Concept A or B serve properties off Sandberg Concepts for Sewer Extension Lane or 3 lots off Merin Road. Concept C shows how gravity sewer could be provided Most of the Rogers Road study area is served with water by the Orange Water and to those lots not served by A or B via a new line along Billabong Lane. Billabong Lane is Sewer Authority(OWASA). Water lines extend eastward from Rogers Road.

Pumps are southeastern corner of the study area. not desirable because they may fail during storms and they involve operating costs for electricity and maintenance. In accordance with existing OWASA policies, benefiting properties would bear the cost of extending water and sewer lines. The Task Force also reviewed the assessment process In March 2007, as part of the Rogers Road Task Force discussions, OWASA staff for neighborhoods pursuing water and sewer service.Task Force members expressed great presented a conceptual layout of a sanitary sewer network that could provide concern over the ability of existing homeowners to bear the cost of installing main lines, service to existing lots within the Rogers Road study area.
