SLIDE 2

Work Completed

Performed elevation survey of key components of the

WWTP equipment in order to study the hydraulic profile

f the plant.
Performed calculations for the sizing of various units and

pipe sizing per flow requirements and loading parameters.

Reviewed previous permitting and design documents as

well as past and existing permits.

Conducted meetings with Jennifer McKnight and Karl

Schlielig in order to assess how the plant is currently being operated and what problems they observe from

perations and managements spectrums.
