SRP’s Santan Valley Generating Station was experiencing equipment reliability issues with an oil water separator (OWS). This work consisted of removing an existing underground oil-water separator (OWS), installation of a below grade vault and installation of a new above ground oil-water separator inside the vault and associated piping and instrumentation.

The Challenge
The possibility of the OWS tank leaking upon excavation presented a substantial environmental concern.
The Solution
Excavating from the sides of the tank first was key in early identification of possible leaks. It was also imperative to switch from hydro excavation to mechanical excavation. By using mechanical excavation, our team was able to more accurately account for any extra moisture in the area around the OWS tank.
The Result
The OWS tank was removed safely, and without any environmental complications or concerns.
