Water Flow Calculator & Wall Extensions
(patent # 7276156)
 
Orignal Trash Guard
Trash Guard Plus

In order to consider Trash Guard screens as an component in any clean water BMP program, the selection of the correct screen size must be based on site specific stormwater runoff flows. Trash Guard offers a cfs stormwater runoff discharge calculator package unlike any seen to date in the sustainable development clean water industry.

Inserts Extended From Wall

All sizes can be extended from the catch-basin wall from One to Eight inches. This extension feature option increases cfs and vertical flow, which the cfs discharge calculator can produce numbers for.

You may download the Runoff Calculator to compute the CFS for any given drainage area and the drainage area for any given CFS up to a 10 year storm. You may download the Hydraulic Analysis Calculator to compute the expected CFS for any size Trash Guard under any debris buildup situation, wall extension width, and catch basin depth. The RCP Flow Calculations shows the amount of flow a reinforced concrete pipe can carry based on diameter and slope.

The Hydraulic Analysis spreadsheet has been developed to illustrate the expected hydraulic behavior of the Trash Guard under certain known operating conditions. These conditions include: described system configurations, downstream tail water and debris accumulations. In the event that conditions occur, which are outside those for which this spreadsheet was developed, the results of this spreadsheet may be in error. In addition, the determination of flow performance relies heavily on standard orifice and weir flow equations, and coefficients listed above and the accuracy of the associated input variables. Therefore, this data cannot be relied upon except under the exact conditions indicated. The user must verify results for specific sites by independent means.
