Flattening the (Diurnal) Curve
Most sewer flows are characterized by repeatable diurnal patterns that vary across weekdays, weekends, and holidays. Differences in land use also are apparent, and distractions and disruptions of daily life often can be observed. The coronavirus pandemic has touched all of us in some way. Normal is simply not normal anymore. Instead, our usual routines at home, work, and school have been replaced by new ones, involving masks, social distancing, frequent hand washing, and evolving restrictions on what is open and what is closed - all in a concerted effort to 'flatten the curve' and control the spread of the virus.
