University of New Hampshire Stormwater Center Tests Pervious Pavement with Triverus at Durham, NH Campus

UNH Tests Pervious Pavement Functionality with Triverus        UNH Tests Pervious Pavement Functionality with Triverus

Before Triverus MCV Cleaning — Water Running Off       After Triverus MCV Cleaning — Water infiltrating

 

In the summer of 2019, the University of New Hampshire Stormwater Center invited Triverus to their campus in Durham, NH, to determine the effectiveness of the Triverus Municipal Cleaning Vehicle (MCV) in pervious pavement cleaning and restoring percolation rates. UNH has several generations of pervious pavements, each installed when major changes or advancements in pavement design or installation occurred.  While each plot is still in use, predictably, percolation rates deteriorated over time.  By the summer of 2019, all their pervious paved surfaces were non-functional.  Over the period of a week, the MCV performed trial pervious pavement cleanings on five such plots. Every treated test plot showed restoration of acceptable percolation rates, even after up to 15 years of non-functionality.  UNHSC published a full review of the process and results of testing in the parking lot of their Alumni Center.
