Crescent fountain, Nike World Campus, Walker Road Entrance
|
 NW Engineers provided the design for realignment of the main delivery line for the Crescent fountain at the Nike World Campus. A number of alternatives were considered to minimize the impact on the myriad of existing utilities at the entrance. The final solution was a mix of ductile iron and pvc materials to tie into. The project was completed in a few weeks.

Banks Water Resources Master Plan, Banks, OR
|
 Assisted in the planning for supplying water to the City of Banks for the next 20 years and estimated costs for the various alternatives. Designed the additions to the water treatment plant including flocculation treatment for a spring water source, a 240,000 ground storage tank to provide chlorine contact time for the treated water, SCADA improvements for monitoring the water plant processes, replacement water transmission main from the large spring water supply to the water treatment plan, and a new water well to supplement their well supply

Tualatin Water Mains, Tualatin, OR
|
 We provided the design for replacing approximately 2,000 feet of 8-inch water main in a fully developed area of the City. The new main replaced a 6-inch asbestos cement main. The water main replacement project was designed in conjunction with the installation of new sanitary sewers in this area. The project required close coordination with all property owners concerning locations of existing water main services on private property. In addition to the design services, NW Engineers also is providing construction phase services for periodic inspections of the project.

Water Conservation & Management Plan
|
.jpg "Chart-Drop-Shad (Small).jpg") The WCMP was prepared in conformance with Oregon Water Resources Department standards. The plan described the potable water service area, population projections for it, reviewed the current water supply, listed all City controlled water rights, and the adequacy/reliability of the water supply. Average and peak usage was reviewed and future usage was projected .In particular the effect of current industrial users was studied. A water conservation plan was established which included four stages of restrictions depending on the severity of the water shortage. The water treatment plant was reviewed for capacity and treatment efficiencies and an intertie with adjacent community was investigated. Finally an estimate of construction cost for the intertie was prepared.

Meadow Lake Water Main, Carlton OR
|
.jpg "plan-drop-shaow (Small).jpg") The only transmission line bringing water into Carlton is supported on the Meadow Lake Bridge. The bridge had deteriorated and was in need of replacement. As part of the replacement project, we designed a new water main both supported on the new bridge and under the new pavement construction each side of the new bridge as part of the bridge project. This included about 1600 LF of 16-inchdiaameter water main. The bridge portion was designed with hanger supports, expansion joint, and was seismically designed to meet all regulations.

Bradwood Landing Pump Station and Intake
|
.jpg "PS-drop (Small).jpg") The dual purpose pump station is designed to extract water from the Columbia (a) to pump into tanker ballasts and (b) to provide the necessary fire water for the planned LNG industrial plant at Bradwood Landing, Clatsop County. The ballast pumps needed to provide 11,000 gal/min and the fire flow pumps 5,500 gal/min flows respectively. Both pump were vertical axial pump types.
