ASTM D8107-18

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D8107 − 17 D8107 − 18
Standard Practice for
Determining Sediment Pond Skimmer Flow Rate
This standard is issued under the fixed designation D8107; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This practice covers the setting up and running of a test to determine the clear water flow rate at various depths of a floating
sediment pond skimmer.
1.2 This practice is limited to large-scale test conditions, and does not address hydraulic modeling or pipe-flow based
calculations.
1.3 The values stated in SI units are to be regarded as the standard.
1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice
D6026, unless superseded by this standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.2 Definitions of Terms Specific to This Standard:
3.2.1 floating sediment pond skimmer, n—a buoyant device that releases/drains water from the surface of sediment ponds, traps
or basins at a controlled rate of flow.
4. Summary of Practice
4.1 This practice is for evaluating the clear water flow rate of a floating sediment pond skimmer versus pond depth, including
details for setting up a performance test that can be used for design characterization as well as quality assurance to determine
product conformance to project specifications.
5. Significance and Use
5.1 This practice covers the guidelines, requirements and procedures for evaluating the flow rate of a floating sediment pond
skimmer versus pond depth. This practice refers to large-scale testing procedures, and is patterned after conditions typically found
This test method is under the jurisdiction of ASTM Committee D18 on Soil and Rock and is the direct responsibility of Subcommittee D18.25 on Erosion and Sediment
Control Technology.

on construction sites within a sediment basin. This practice outlines test preparation, test execution, data collection, data analysis
and reporting procedures for any size calibrated basin.
6. Apparatus
6.1 Apparatus/Facility:
6.1.1 Testing is performed in a calibrated basin (that is, it has a known surface area at any known depth) of sufficient size to
facilitate multiple, accurate depth readings under the expected flow rates, but not less than 0.9 m deep × 1.2 m wide × 6.1 m long.
A typical basin is shown in Fig. 1
6.1.2 The basin shall be outfitted with a skimmer discharge pipe having a diameter no smaller than that of the pipe joining it
to the floating skimmer head. The discharge pipe shall have a valve or stopper that can be controlled or removed/replaced from
the outside of the basin to initiate and stop flow through the skimmer. It is also recommended to also have a valved drainage pipe
