If you were to work at a firm for 50 years or stay married to the love of your life for 50 years, would you say that was a remarkable milestone? Would one consider this to be a life time of service where congratulations are in order? So, tell me, when a design engineer chooses to use a pipe product that has an anticipated design service life of
After having successfully completed a new professional development hour (PDH) article for Informed Infrastructure on the topic of buried culverts and service life, I was struck by the complexity of what may seem, at first blush, to be a relatively straightforward project. Specifically – the importance of the backfill material selection process.Not
Three Components of Infiltration System DesignCommon infiltration practices include drywells, bioretention, permeable pavement, infiltration trenches, infiltration basins, and subsurface infiltration galleries. Regardless of their form, all infiltration systems have three primary components: storage, treatment, and infiltration.1. StorageRetention
An appropriately designed and manufactured high performance biofiltration system combines the benefits of natural biofiltration with the reliable and predictable performance of an engineered system. Each high performance biofiltration system utilizes a multifaceted approach including physical, chemical and biological processes to capture,
