Specialized Skills

One of the strengths of the wastewater industry is its strong do-it-yourself attitude. However, clever professionals know that sometimes solving a problem requires looking elsewhere.

This month’s “A Rocky Problem” is a prime example of this. When an unusual grit pumping system failed to perform as expected, the designers looked to the mining industry for solutions. The designers reasoned that if the mining industry can pump rock slurries hundred of miles, it could help the plant move grit 50 ft (15 m).

The plan worked, and now the plant has a grit pumping system that operates without clogging and eliminates costly and troublesome annual maintenance tasks.

In another example of when and how to trust experts, “Keys to Smart Bypass Pumping Design Criteria,” provides essential information you need to have in hand to ensure that your bypass has the volume and pumping capacity to handle the flows.

Whether you’re planning to construct and operate the bypass yourself or contract out the job, proper flow monitoring data is essential. Specialized flow monitoring experts can help to determine the true historical peak flows needed to design an adequate bypass.

While unique or persistent challenges often require skills and advice that fall outside of the municipal wastewater industry, having the pluck to do whatever it takes to solve the problem is familiar ground.
