Wastewater Treatment Plant Influent Flow Meter Evaluation
August 2021
Background
The City of Pasco's (City) Wastewater Treatment Plant (WWTP) influent flow meter readings are
inconsistent between the values reported in the City's control system and the values calculated with
open channel weir equations.
The City has requested RH2 Engineering, Inc., (111-12) evaluate the discrepancies between the control
system calculations and open channel weir equations to assist in reconciling the differences.
Task 1— Influent Flow Meter Evaluation
Objective: Evaluate the differences between the control system calculations and open channel weir
equations in an attempt to reconcile the differences between these two datasets.
Approach:
1.1 Meet with City operations staff at the WWTP to review the influent flow weir configuration.
1.z Calculate flows based on applicable influent weir equations and compare to the control system
1.3 calculations.
Recommend updates to equations or flow monitoring equipment based on the results of
1.4 subtask 1.2.
Prepare quick -reference charts and tables for City operations staff to identify the influent flow
based on measured flow heights and the number of clarifiers online.
Assumptions:
• RH2 will rely upon the accuracy and completeness of information, data, and materials
generated or produced by the City or others in relation to this Scope of Work.
• RH2 cannot guarantee the differences between the control system calculations and open
channel weir equations can be reconciled. If additional evaluation is necessary beyond the
budget of this Task Authorization, an amendment may be mutually negotiated between the
City and RH2.
