The ADS ECHO can help you judge the timing of I/I by observing the quickness of the flow response and the rate at which the system recovers. ECHOs can also be used to indicate if the system becomes surcharged. However, if the sewer moves into backwater or is restricted in […]
When determining sewer basin and sub-basin areas for an I/I analysis, do you typically use the entire acreage of the sub-basin, or do you subtract out undeveloped areas, native growth areas, critical areas, etc. for a better comparison of I/I rates between sub-basins.
The primary, independent recommendation for rain gauge density in the United States is from the American Society of Civil Engineers (ASCE) and the Water Environment Federation (WEF). They recommend a rain gauge density of one rain gauge for every 5 to 10 square miles. There are some finer points to […]
Most I/I studies look to quantify rainfall entering a sewer system as I/I. As a result, frozen precipitation events that occur during an I/I study are often ignored. Keep in mind that the most intrusive effects of I/I on a sewer system result from rainfall, not snowfall. Some municipalities in […]
A double mass analysis is one method to compare cumulative rainfall from various rain gauges where consistency between rain gauges is deemed an indicator of proper operation. Keep in mind that a double-mass analysis is generally intended for use evaluating data over long time periods, not individual rainfall events. For […]
