Deploying Drop-Over Sound Enclosures To Manage Excessive Noise
For wastewater treatment sites which were once far from housing developments, and are now being encroached by new developments, retrofit sound enclosures can lessen the noise level associated with the operation of your wastewater treatment equipment.
For those sites which are experiencing this type of situation, HPA provides the solution: Retrofit Sound Enclosures, whether individual enclosures, or entire buildings. The following images show an initial deployment where no homes existed near the perimeter of the wastewater treatment plant, and then years later, housing developments began cropping up, and the residents complained about the noise level. By deploying HPA’s sound enclosures, the problem was eliminated and even allowed the equipment to be better protected from the weather while extending the life of the blower packages.

In examining this situation in greater detail, you can see these advantages in this single building:
- We incorporated a pair of doors for easy access and maintenance.
- We placed thermostatically controlled air vent fans above each of the three packages to manage the air flow into and out of the enclosure.
- So that no piping needed to be dismantled or rerouted, we incorporated flashing so that the enclosure could be built around the existing piping.
- Additional electrical connections to power the vent fans and lights were made possible from existing lines which terminated in the blower packages.
- We can also relocate gauges and digital read-outs onto the side of the enclosure(s) to simplify the effort associated with reading these items.
The bottom line: HPA gets it done. No gimmicks, no canned solutions. Just smart, tough, insightful engineering building custom solutions to meet your exact needs.
