Bell Design Company provided inspection services for the City of White Salmon’s $5 million water system improvements. The project included contracts for well drilling and development, distribution system development, reservoir construction, and the construction of a large pump station facility.
The projects all had different prime contractors and a large number of subcontractors. As with all construction, especially site development where subsurface condition can vary, inevitable snags and differing condition will occur. BDC was able to keep the projects running on time and budget so that the City of White Salmon was taken off the Boil Water Order on schedule, and as promised by the Mayor to the citizens of White Salmon.
BDC was the project engineer for the City of White Salmon’s water system improvements, including two reservoirs, a well field (two wells), accompanying waterlines, and improvements to the current system. BDC provided study, predesign, design, and services during construction. These projects included extensive site work and permitting.
BDC provided all the siting and surveying services associated with these projects.
BDC managed these multidisciplinary projects, which included oversight of archeologists, biologists, hydro-geologists, geophysics, and geotechnical engineers. BDC also coordinated and assisted in obtaining permits from such agencies as WSDOT, WSDOE, WSDOH, and Klickitat County building and planning departments. BDC also assisted the City in administering and complying with the requirements of the Community Block Development and other grants that were used to fund these projects.
SEPAs were obtained for the projects presented below:
Powerhouse Well #1 and Booster Pump Station
Components of this project included the design and project construction management of a 40 X 50 foot booster pump station that has a maximum capacity of 4200 gpm. The design included all site work and the approach road for the pump station.
The project also involved developing a supervisory control and data acquisition (SCADA) system to control the operation of the pump station and the City’s reservoirs. The pump station is complete with climate control and a 400 KVA backup generator that automatically switches from the PUD power with any occurrence of low voltage or voltage imbalances.
2005 White Salmon Water Master Plan
Bell Design Company was contracted by the City of White Salmon to complete a new water master plan to satisfy the Washington State Department of Health’s requirements. The City had recently changed the operation of their water system significantly enough that the department felt the old master plan no longer accurately reflected the operation of the system.
Elements of the water master plan included a well head protection plan for the City’s two new wells, the development of a cascading pressure reducing system to address the significant changes in elevation of the system and the water pressures that result from these elevation changes, significant hydraulic modeling of the system and a capital improvements and financial plan to ensure that the City could meet its contracted requirements.
