Body
SUMMARY/KEY POINTS
The North Wastewater Reclamation Facility (NWRF) completed its expansion project in 2020, and this project aims to address improvements that were not completed as part of that expansion project.
BACKGROUND OF SUBJECT MATTER:
The Town of Erie NWRF currently has only one mechanical bar screen with the only alternative being a manual screen. A second screen is necessary for redundancy if the current screen breaks down.
The facility discharges its effluent to Boulder Creek through a pipeline that runs along the east and north banks of the NWRF Re-Use Reservoir. Water from the NWRF Re-Use Reservoir also discharges into Boulder Creek at the same location and follows the same alignment, but through a separate pipeline. It has proven difficult to monitor and sample flows from each source separately. The Town desires to combine the pipes and have a single flow and sampling station located at the discharge into Boulder Creek so that all flows are accounted for in the same location. Doing so will ensure that all samples are representative, and flow into Boulder Creek is accurate.
Currently there is one 250 hp vertical turbine pump in the Non-Potable Pump Station. The pump station was designed and constructed to accommodate two additional 300 hp pumps. Due to increased demand on the non-potable system the second, and possibly third, pump needs to be added for redundancy and for additional capacity.
The current HVAC system in the headworks building is insufficient and creates a hazardous environment for employees to work in. Current HVAC/Ventilation system is to be evaluated and upgraded to meet the minimum air exchange requirements for extended occupancy as well as odor control measures to address the increased exhaustion of air. The flows and loading to the facility are increasing consistently, and the ability to run various combinations of blowers is necessary to keep up with these demands. A fifth blower will add flexibility and redundancy to the facility.
All of the improvements described will help to improve operations and redundancy at the existing facility.
