Scope and Methodology
Introduction
Providence Health & Services entered into an agreement with ADS Environmental Services to conduct flow monitoring at (9) nine metering locations in the Santa Monica,CA Sanitary Sewer Collection System. The study was contracted for a fourteen (14) day period. The objective of this study was to measure depth, velocity, and quantify flows. Data obtained will be used for development planning purposes.
Project Scope
The scope of this study involved using a flow monitor to quantify wastewater flows at the designated locations for the 14-day time period. Specifically, the study included the following key components.
• Investigate the proposed flow-monitoring site for adequate hydraulic conditions. • Flow monitor installation.
• Flow monitor confirmations and data collections.
• Flow data analysis.
Equipment installation was accomplished on April 19, 2017. The monitoring period began on April 20, 2017 and was completed on May 03, 2017 . At the conclusion of the study period, the equipment was removed.
Flow Monitoring Equipment
The ADS FlowShark Triton monitor was selected for this project. This flow monitor is an area velocity flow monitor that uses both the Continuity and Manning's equations to measure flow.
The ADS FlowShark Triton monitor consists of data acquisition sensors and a batterypowered microcomputer. The microcomputer includes a processor unit, data storage, and an on-board clock to control and synchronize the sensor recordings. The monitor was programmed to acquire and store depth of flow and velocity readings at 5-minute intervals.
The FS Triton monitor features cross-checking using multiple technologies in each sensor for continuous running of comparisons and tolerances. The FS Triton monitor can support two (2) sets of sensors. The sensor option used for this project was: The Peak Combo Sensor. This sensor is installed at the bottom of the pipe and includes three types of data acquisition technologies.
The up looking ultrasonic depth uses sound waves from two independent transceivers to measure the distance from the sensor upward toward the flow surface; applying the speed of sound in the water and the temperature measured by sensor to calculate depth.
The pressure depth is calculated by using a piezo-resistive crystal to determine the difference between hydrostatic and atmospheric pressure. The pressure sensor is temperature compensated and vented to the atmosphere through a desiccant filled breather tube.
To obtain peak velocity, the sensor sends an ultrasonic signal at an angle upward through the widest cross-section of the oncoming flow. The signal is reflected by suspended particles, air bubbles, or organic matter with a frequency shift proportional to the velocity of the reflecting objects. The reflected signal is received by the sensor and processed using digital spectrum analysis to determine the peak flow velocity.
Installation
Installation of flow monitoring equipment typically proceeds in four steps. First, the site is investigated for safety and to determine physical and hydraulic suitability for the flow monitoring equipment. Second, the equipment is physically installed at the selected location. Third, the monitor is tested to assure proper operation of the velocity and depth of flow sensors and verify that the monitor clock is operational and synchronized to the master computer clock. Fourth, the depth and velocity sensors are confirmed and line confirmations are performed.
In pipes up to 42 inches in diameter, the sensors are mounted on expandable stainless steel rings, inserted at least a foot upstream into influent pipes and tightened against the inside walls of the pipes. Influent pipe installations reduce the influences of turbulence and backwater often caused by changes in channel geometry in manholes.
Data Collection, Confirmation, and Quality Assurance
Data collects were done remotely via wireless connect on a weekly basis via ADS Field Representatives. Weekly, during the monitoring period, field crews visit each monitoring location to verify proper monitor operation and document field conditions.
The following quality assurance steps are taken to assure the integrity of the collected data:
Measure power supplies: monitors were powered by dry cell battery packs.
Voltages were recorded and battery packs replaced, as necessary. Separate batteries provided back-up power to memory allowing primary batteries to be replaced without loss of data.
Clock synchronization: Field crews synchronized monitor clocks to master clocks.
Confirm depth and velocity readings: Field crews descended into meter manholes to manually measure depths and velocities and compare them meter readings to confirm that they agreed. They also measured silt levels, if any, in the inverts of the pipes. Silt areas were subtracted from flow areas to compute true areas of flow.
Confirm average velocities through cross-sectional velocity profiles: Since ADS velocity sensors measure peak velocity, field crews collected cross-sectional velocity profiles in order to develop a relationship between peak and average velocity in lines that meet the hydraulic criteria.
Upload and Review Data: Data collected from the monitors were uploaded and reviewed by a Data Analyst for completeness, outliers and deviations in the flow patterns, which indicate system anomalies or equipment failure.
Flow Quantification Methods
There are two main equations used to measure open channel flow: the Continuity Equation and the Manning Equation. The Continuity Equation, which is considered
the most accurate, can be used if both depth of flow and velocity are available. In cases where velocity measurements are not available or not practical to obtain, the Manning Equation can be used to estimate velocity from the depth data based on certain physical characteristics of the pipe (i.e. the slope and roughness of the pipe being measured). However, the Manning equation assumes uniform, steady flow hydraulic conditions with non-varying roughness, which are typically invalid assumptions in most sanitary sewers. The Continuity Equation was used exclusively for this study.
Continuity Equation
The Continuity Equation states that the flow quantity (Q) is equal to the wetted area (A) multiplied by the average velocity (V) of the flow.
Q = A * V
This equation is applicable in a variety of conditions including backwater, surcharge, and reverse flow.
Data Analysis and Presentation
Data Analysis
A flow monitor is typically programmed to collect data at 5-minute intervals throughout the monitoring period. The monitor stores raw data consisting of (1) the ultrasonic depth, (2) the peak velocity and (3) the pressure depth. The data is imported into ADS's proprietary software and is examined by a data analyst to verify its integrity. The data analyst also reviews the daily field reports and site visit records to identify conditions that would affect the collected data.
Velocity profiles and the line confirmation data developed by the field personnel are reviewed by the data analyst to identify inconsistencies and verify data integrity.
Velocity profiles are reviewed and an average to peak velocity ratio is calculated for the site. This ratio is used in converting the peak velocity measured by the sensor to the average velocity used in the Continuity equation. The data analyst selects which depth sensor entity will be used to calculate the final depth information. Silt levels present at each site visit are reviewed and representative silt levels established.
Occasionally the velocity sensor's performance may be compromised resulting in invalid readings sporadically during the monitoring period. This is generally caused by excessive debris (silt) blocking the sensor's crystals, shallow flows (~< 2") that may drop below the top of the sensor or very clear flows lacking the particles needed to measure rate. In order to use the Continuity equation to quantify the flow during these periods, a Data Analyst and/or Engineer will use the site's historical pipe curve (depth vs. velocity) data along with valid field confirmations to reconstitute and replace the false velocity recordings with expected velocity readings for a given historical depth along the curve.
Selections for the above parameters can be constant or can change during the monitoring period. While the data analysis process is described in a linear manner, it often requires an iterative approach to accurately complete.
Data Presentation
This type of flow monitoring project generates a large volume of data. To facilitate review of the data, results have been provided in graphical and tabular formats. The flow data is presented graphically in the form of scattergraphs and hydrographs.
These tables show the flow rate for each day, along with the daily minimum and maximums, the times they were observed, the total daily flow, and total flow for the month (or monitoring period). The following explanation of terms may aid in interpretation of the tables and hydrographs.
DEPTH - Final calculated depth measurement (in inches)
QUANTITY - Final calculated flow rate (in MGD)
VELOCITY - Final calculated flow velocity (in feet per second) REPORT TOTAL - Total volume of flow recorded for the indicated time period (in MG)

Overview
Site Broad06N functioned under normal conditions during the period Thursday, April 20, 2017 to Wednesday, May 03, 2017 . No surcharge conditions were experienced at this location (See Observation Table For More Details).
Review of the Scattergraph shows that free flow conditions were maintained throughout the study period.
Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted and support the relative accuracy of the flow monitor at this location. Confidence in data accuracy is lower than typical, due to low flow conditions and the small pipe.
Observations
Average flow depth, velocity, and quantity data observed during Thursday, April 20, 2017 to Wednesday, May 03, 2017 , along with observed minimum and maximum data, are provided in the following table. The values presented are based on 5-minute data. In regards to depth, this site flows at approximately 17.2% full during the typical average depth of 0.86 inches.

Overview
Site SAN02N functioned under normal conditions during the period Thursday, April 20, 2017 to Wednesday, May 03, 2017 . This line exhibits the presence of an hydraulic jump when operating between 2.0 and 2.7 inches in depth. This condition is experienced when flow transitions from supercritical to subcritical flow.

Overview
Site SAN03 functioned under normal conditions during the period Thursday, April 20, 2017 to Wednesday, May 03, 2017 . The hydraulic conditions in this stretch of pipe are near the lower detection limit of an area velocity type meter. Depth in this line is typically low and stagnant. No surcharge conditions were experienced at this location (See Observation Table For More Details).
Review of the Scattergraph shows that free flow conditions were maintained throughout the study period.
Flow depth and velocity measurements recorded by the flow monitor are consistent with field confirmations conducted and support the relative accuracy of the flow monitor at this location. Confidence in data accuracy is lower than typical, due to hydraulic conditions.
Observations
Average flow depth, velocity, and quantity data observed during Thursday, April 20, 2017 to Wednesday, May 03, 2017 , along with observed minimum and maximum data, are provided in the following table. The values presented are based on 5-minute data. In regards to depth, this site flows at approximately 9.0% full during the typical average depth of 1.08 inches.
