Potable water tank inspections and cleanings are a
growing part of our business at M&K Diving, and our unique specialty.
The A.W.W.A. (American Water Works Association) recommends inspection
and cleaning of potable water reservoirs on a five-year rotation. Many
states are now mandating these guidelines for all potable water
structures. M&K Diving can assist operators with compliance by
inspecting and cleaning these structures on a regular rotation.
In our experience, the amount of bottom material
found in potable water structures is primarily influenced by the raw
water source. Lake and river sources carry more sediment into the system
than water derived from a driven well.
We have experience servicing all types of
storage tanks: in-ground concrete, blasted rock; on-ground steel or
concrete, and elevated steel. We have worked with reservoirs containing
Hypalon liners and older structures that may include wood in their
design.
M&K Diving’s video inspections utilize either a
diver-mounted camera system or Remotely Operated Vehicle (ROV). Both
methods provide top-quality, real-time video feeds, recorded for
permanent record. Diver communication with topside personnel is also
recorded during inspections of that type. Our video equipment is the
best in the industry and puts the client on bottom with the divers, in
real-time.
Other storage tank services include:
- Removal of all material in
the tank, including sediment, sand, and coagulated materials
- Underwater leak detection
- Repairs to exposed re-bar,
concrete spalls, or internal plumbing
- Cathodic protection system
maintenance and repair
- Inspections of the
ventilation screen and hardware
- Inspection of the hatches
- External and internal
coating inspections
- Written reports, including
both recorded video and still photography
- Inspections done with the
ROV
Why use divers instead of
draining?
-
It is far
more cost effective than draining the tank
-
No
interruption in service to your customers
-
No extra cost
involved in putting your system back on-line (i.e. shocking the
system)
-
No extra cost
for vacuum trucks to remove the sediment once drained
-
Municipality
fire protection is not compromised
-
No confined
space permits required
-
Smaller
systems, with only one storage tank, remain on-line during cleaning
-
Small
communities may not have the staff to handle the extra work involved
in cleaning a tank or reservoir
-
Minimal
treated water is wasted
