TOO MUCH RAINFALL?

Whether you're designing a stormwater pollution prevention plan or monitoring stormwater runoff at a waste-water treatment plant, you need to know about excessive rainfall.

STORMWATER POLLUTION PREVENTION PLANS

 Your SWPPP has to be designed for the worst case rainfall. But what is the best way find that out? A recent IECA-sponsored webinar highlighted the use of the NOAA Atlas 14 as a way to know maximum rainfall potential.

WASTEWATER TREATMENT PLANTS

  During periods of intense rainfall, not only can stormwater carry higher amounts of pathogens, but it also increases the flow rate to a wastewater treatment facility. Higher flow rates can exceed the facilities’ treatment capacity, impacting treatment performance.

KNOW THE MAXIMUM RAINFALL

  WaterWatch PRO shows you the maximum rainfall for locations being monitored. This way, you'l know the most that has fallen. From the Precip History for your location, you'll see View Historic Maximums. Click on that to display the most that has fallen in a 1 and 24-hour period over various year frequencies. Often referred to as the "100-year" event, these are excessive rainfall that normally prompts necessary action.

REAL-TIME DATA

  When actual rainfall detected by WaterWatch PRO exceeds any of the NOAA Atlas 14 values for your location, the amounts in the Precip History turn red. This helps stormwater monitoring professionals know when there's been too much rain. When you upgrade to the Silver or Gold feature package, you can receive a text notification when this happens as well.
