In order to keep pace with a fast growing area in northeast Sherwood, City officials looked to Fisher & Arnold, Inc. to develop cost effective solutions to provide increased collection system capacities along Gap Creek and expand treatment capability at their Indianhead Wastewater
Treatment Facility.

Fisher & Arnold, Inc. worked with the City to develop a design increasing the capacity of the existing 0.35 MGD sequencing batch reactor (SBR) facility to 1.10 MGD. In conjunction with this design Fisher & Arnold, Inc. also designed a new 1,300 gpm submersible pump station to deliver sewage from the Gap Creek basin to the expanded Indianhead Wastewater Treatment Facility.
