LATEST INSIGHTS ON WASTEWATER

  • A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.
  • Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
  • Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
  • Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.

  • Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
  • Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
