Using Divers

SE Diving Services, LLC uses divers to inspect in potable water tanks. Divers provide an thorough and complete inspection.

Using ROVs

We have state-of-the art ROVs (Remotely Operated Vehicles) for inspection of tanks when requested. ROV inspections can provide most of the information needed to satisfy inspection requirements of all states in our service area.

All inspections are done according to ASNT/NACE/AWWA standards.

AWWA's C652-92 standard.requires that equipment, including divers in rubber suits, be sprayed with a chlorine solution of no less than 200 ppm before being introduced into potable water reservoirs.
The formula SE Diving uses: no less than 6 oz.of a six (6) percent chlorine bleach per two gallons of water to form our disinfectant solution at a minimum strength of 200 ppm.. All equipment used in potable water tanks is reserved solely for use in potable water and is not used in other applications.
