West Linn Sanitary Master Plan
|
This project completed by a NW Engineers principal while at another firm, required that all of the sanitary sewers in West Linn be surveyed. Planning data was utilized to predict future flow rates due to growth, and a model was created to estimate the effects of these future flows on the system. Recommendations were made for sewers which required to be increased in size due to this growth. In addition, sewers serving older areas of town were recommended to be systematically replaced because of their age and to reduce infiltration/inflow entering the sewers from these older mains. Pumping stations were also reviewed and recommendations for upgrades were made. A Capital Improvement Program was prepared which scheduled all recommended improvements.
