Indian Hills, Missouri

The 24th started out as a fully packed day.  We had a community with two small water tanks to inspect, followed by another community with six tanks that needed to be inspected and possibly cleaned. 

Upon arrival at the first tank in Indian Hills, we discovered that the tank hatch was not wide enough to allow access to a suited diver.  My lead decided to perform a scaled down video inspection.

We removed the camera and flashlight from one of our Kirby Morgan 17-B dive helmets and attached them to a copper tube sled.  The sled was then lowered into the tank and allowed for a pretty good inspection.  It also allowed us to wrap up the job very quickly. 

My pictures from this small job:

The tiny underground tank - the hatch is the round pipe on the far side of the tarp.

Afterward, the utility folks and my lead decided that the second tank didn't need to be inspected, so we drove on to the Emmaus Homes community (about 30 minutes down the road). 

Emmaus Homes is a private community that provides housing and services to people with developmental disabilities.  We arrived mid-morning on Friday and waited for an hour while my team lead tracked down someone who was in charge of the water tanks.  Our contact was apparently off that day but hadn't let my lead know when they spoke on the phone one day prior.  After finding someone, they went and looked at the tanks and discovered that the six "hot dog" shaped tanks all had bolted hatches.  24 rusted bolts would need to be removed to provide access to each tank.  This translated to an estimated four hours of work... work that should have been done prior to our arrival.  To further complicate the situation, nobody in the public works office was available to work on Saturday, and the job was easily a 1.5 to 2-day job. 

We had a big job booked in Des Moines, IA on Sunday, so we had to leave Emmaus Homes and their job will need to be rescheduled.
