Methods for Estimating Spill Volume A variety of approaches exist for estimating the volume of a sanitary sewer spill. This Appendix documents the three methods that are most often employed. The person preparing the estimate should use the method most appropriate to the sewer overflow in question and use the best information available.
Method 1: Eyeball Estimate
The volume of small spills can be estimated using an “eyeball estimate”. To use this method imagine the amount of water that would spill from a bucket or a barrel. A bucket contains 5 gallons and a barrel contains 50 gallons. If the spill is larger than 50 gallons, try to break the standing water into barrels and then multiply by 50 gallons. This method is useful for contained spills up to approximately 200 gallons.
Method 2: Measured Volume
The volume of most small spills that have been contained can be estimated using this method. The shape, dimensions, and the depth of the contained wastewater are needed. The shape and dimensions are used to calculate the area of the spills and the depth is used to calculate the volume.
Common Shapes and Dimensions
Step 1 Sketch the shape of the contained sewage (see figure above).
Step 2 Measure or pace off the dimensions.
Step 3 Measure the depth at several locations and select an average.
Step 4 Convert the dimensions, including depth, to feet.
Step 5 Calculate the area in square feet using the following formulas:
Rectangle: Area = length (feet) x width (feet) Circle: Area = diameter (feet) x diameter (feet) x 0.785
Triangle: Area = base (feet) x height (feet) x 0.5
Step 6 Multiply the area (square feet) times the depth (in feet) to obtain the volume in cubic feet.
Step 7 Multiply the volume in cubic feet by 7.5 to convert it to gallons
2
Methods for Estimating Spill Volume Page 2
Method 3: Duration and Flowrate
Calculating the volume of larger spills, where it is difficult or impossible to measure the area and depth, requires a different approach. In this method, separate estimates are made of the duration of the spill and the flowrate. The methods of estimating duration and flowrate are:
Duration
The duration is the elapsed time from the time the spill started to the time that the flow was restored.
Start Time: The start time is sometimes difficult to establish. Here are some approaches:
1. Local residents can be used to establish start time. Inquire as to their observations.
Spills that occur in rights-of-way are usually observed and reported promptly. Spills that occur out of the public view can go on longer. Sometimes observations like odors or sounds (e.g. water running in a normally dry creek bed) can be used to estimate the start time.
2. Changes in flow on a downstream flowmeter can be used to establish the start time.
Typically the daily flow peaks are “cut off” or flattened by the loss of flow. This can be identified by comparing hourly flow data during the spill event with flow data from prior days. This method will likely only be effective with consistent weather.
3. Conditions at the spill site change over time and can be used to establish the start time. Initially there will be limited deposits of toilet paper and other sewage solids. After a few days to a week, the sewage solids form a light-colored residue. After a few weeks to a month, the sewage solids turn dark. The quantity of toilet paper and other materials of sewage origin increase over time. These observations can be used to estimate the start time in the absence of other information. Taking photographs to document the observations can be helpful if questions arise later in the process. This method is valid for spills that have been occurring for a long time and may be used in conjunction with either of the above methods.
4. It is important to remember that spills may not be continuous. Blockages are not usually complete (some flow continues). In this case the spill would occur during the peak flow periods (typically 10:00 to 12:00 and 13:00 to 16:00 each day). Spills that occur due to peak flows in excess of capacity will occur only during, and for a short period after, heavy rainfall.
End Time: The end time is usually much easier to establish. Field crews on-site observe the “blow down” that occurs when the blockage has been removed. The “blow down” can
3
Methods for Estimating Spill Volume Page 3
also be observed in downstream flowmeters.
Flow Rate
The flowrate is the average flow that left the sewer system during the time of the spill.
There are three common ways to estimate the flowrate:
1. The San Diego Manhole Flowrate Chart: This chart, included as at the end of this appendix, shows sewage flowing from manhole covers at a variety of flowrates. The observations of the field crew can be used to select the appropriate flowrate from the chart. If possible, photographs are useful in documenting basis for the flowrate estimate.
2. Flowmeter: Changes in flows in downstream flowmeters can be used to estimate the flowrate during the spill.
3. Counting Connections: Once the location of the spill is known, the number of upstream connections can be determined from the sewer maps. Multiply the number of connections by 200 to 250 gallons per day per connection or 8 to 10 gallons per hour per connection.
For example: 22 upstream connections * 9 gallons per hour per connection
= 198 gallons per hour / 60 minutes per hour
= 3.3 gallons per minute
Spill Volume
Once duration and flowrate have been estimated, the volume of the spill is the product of duration (hours or days) and the flowrate (gallons per hour or gallons per day).
For example: Spill start time = 11:00
Spill end time = 14:00
Spill duration = 3 hours
3.3 gallons per minute x 3 hours x 60 minutes per hour
= 594 gallons

RICHARDSON BAY SANITARY DISTRICT
WATER QUALITY MONITORING PROGRAM
INTRODUCTION
This Water Quality Monitoring Program provides the Agency’s response activities and standard
operating procedures to be utilized in the OERP, in the event a sanitary sewer overflow (SSO)
exceeds 50,000 gallons. This program is reviewed periodically and may be updated as necessary.
State Water Resources Control Board Order No. WQ 2013-0058-EXEC, Amending Monitoring
And Reporting Program For Statewide General Waste Discharge Requirements For
Sanitary Sewer Systems (Effective September 9, 2013), requires the following:
SSO WDR Section D. Water Quality Monitoring Requirements
To comply with subsection D.7(v) of the SSS WDRs, the enrollee shall develop and implement
an SSO Water Quality Monitoring Program to assess impacts from SSOs to surface waters in
which 50,000 gallons or greater are spilled to surface waters. The SSO Water Quality Monitoring
Program, shall, at a minimum:
1. Contain protocols for water quality monitoring.
2. Account for spill travel time in the surface water and scenarios where monitoring may not
be possible (e.g. safety, access restrictions, etc.).
3. Require water quality analyses for ammonia and bacterial indicators to be performed by
an accredited or certified laboratory.
4. Require monitoring instruments and devices used to implement the SSO Water Quality
Monitoring Program to be properly maintained and calibrated, including any records to
document maintenance and calibration, as necessary, to ensure their continued accuracy.
5. Within 48 hours of the enrollee becoming aware of the SSO, require water quality
sampling for, at a minimum, the following constituents:
i. Ammonia
ii. Appropriate Bacterial indicator(s) per the applicable Basin Plan water quality
objective or Regional Board direction which may include total and fecal coliform,
enterococcus, and e-coli.
Additionally, for spills greater than 50,000 gallons, an SSO Technical Report is required and
must be submitted within 45 calendar days from the SSO end date. The SSO Technical Report
requirements are described in Element VI of the OERP.
RBSD Water Quality Monitoring Program
Updated June 2014
Page 2
SAFETY
Be aware of safety issues and do not subject personnel to unsafe conditions in order to comply
with this Water Quality Monitoring Plan. Scenarios where monitoring may not be possible may
include, but are not limited to, heavy rain/storm events where access points have been
compromised, flooding around low level areas, or fast-moving water. Employ the buddy system
as required to maximize employee safety when sample collection is required.
ESTIMATION OF SPILL TRAVEL TIME
The follow methods are recommended to estimate spill travel time and direction:
Method-1; use a velocity probe if available to determine the rate of flow in the surface
water or
Method-2; take visual ft/sec measurement from above, based on floating debris, to
estimate the number of feet the debris has traveled in seconds.
Either method will provide a means to estimate the distance traveled and identify where the SSO
may be headed within the waterway.
WATER QUALITY SAMPLING PROCEDURES
In the event an SSO reaches a surface water or (flowing) drainage channel tributary, take
samples for spills less than 50,000 gallons as appropriate and within 48 hours for spills
greater than 50,000 gallons. The purpose of water quality sampling is to determine the
nature and extent of the impact of the SSO.
When sampling an SSO, take a minimum of three separate sample sets as conditions
allow. Water quality sampling should not be given precedence over stopping the spill or
protection of public health. One sample shall be located 500’ upstream of the discharge
location. The second sample shall be taken at the discharge location. A third sample shall
be taken 1000’ downstream of the discharge location. Distances may be adjusted by the
local health authority.
Sample for Total and Fecal Coliform, eColi, and Ammonia as a minimum. Conduct
additional sampling for BOD and pH if practical.
Additional follow-up samples are recommended to confirm the extent that the impact
reverts back to baseline levels. Follow-up samples may be used to determine if posting of
warning signs should be discontinued (if signs were posted).
Collaboration with the County Health Department should continue until closure is
obtained.
Do not forget to take into account Spill Travel Time.

WATER QUALITY SAMPLING EQUIPMENT
The following list describes equipment that should be stocked and readily available for each
water quality sampling event.
Personnel protective equipment including latex/nitrile gloves and eye protection
3 – 100 mL sterile plastic containers for coliform analysis.
3 – 1 Liter Poly containers for BOD.
3 – 500 mL Poly containers preserved with H2SO4 for Ammonia analysis.
3 – sterile funnels
1 – Sample Collection Container
Cooler with ice packs
Chain of Custody forms
Ensure that there are adequate quantities of sample containers-kits if there are more
than three sample locations.
WATER QUALITY SAMPLING PROCEDURE
1. Put on all required protective equipment including latex/nitrile gloves and eye protection
2. Use the 100 mL sterile container for coliform, 1-liter poly container for BOD and 500mL
poly container for ammonia. Ammonia sample requires preservation with H2SO4 .
3. Collect three sets of samples for each incident:
a. 500 feet upstream
b. At the SSO entry point
c. 1000 feet downstream
4. Collect all grab samples approximately 3’ - 6” below the surface (or if shallower, as close
as possible to this depth) to avoid sampling debris or scum from the surface.
5. Collect the sample in a safe manner in the middle of the flow, against the direction of
water flow.
6. Rinse the sample collection container.
7. Collect sample in sample collection container and photo-document the locations.
8. Transfer sample from sample collection container to individual sample bottle(s).
9. Leave approximately one inch of head space in individual sample bottles. Do not overfill.
10. Once the lid is opened for the individual sample bottle, do not touch the inside surface of
the bottle or lid.
11. For the sample bottles that contain a preservative, take care to keep the preservation
material in the container.
12. Immediately place all sample bottles on ice.
