Water tanks designed and built for the marine environment
Custom Built Water Tanks
Water, Waste and Grey Water Tanks
BETTER BY DESIGN
Over the past years TEK-TANKS designers and engineers have developed
a water tank construction system using high strength, advanced
polyethylene materials that overcomes the persistent corrosion
and weight problems of stainless steel and the mechanical failure
of flexible bag style tanks. Over 40% of our current work is building
replacement water tanks for boats previously fitted with mechanically
unreliable flexible bags or stainless and aluminium tanks with
electrolysis problems.
BAFFLES FOR STRENGTH AND SECURITY
TEK-TANKS standard specification includes baffles placed approximate
every 300 mm. On larger tanks these are locked into position by
means of an interlocking pin and ribs situated under the top panel.
This design feature prevents the top of the tank from lifting
when under pressure.
These carefully planned internal baffles also perform two additional
important functions. Firstly, they introduce immense rigidity
to the design of the tank, and secondly, they cleverly limit the
dynamic movement of contents, thus minimising the destructive
pounding forces against the tank body.
COMPUTER AIDED DESIGN
After being computer designed on our CAD system, components for
each tank are cut to exact shape and size. These panels are then
fitted together and welded in place using the latest hot gas extrusion
welding systems.
CUSTOM DESIGN AND PRODUCTION
Water
and waste holding tanks built from rigid polyethylene lend themselves
to one-off production because there are no expensive mould tools
to build. Tanks are of all welded construction and built to the
customers own design, but to TEK-TANKS demanding and proven specifications.
Polyethylene cannot be easily curved, but multifaceted shapes
normally solve most design problems.
TASTE FREE WATER
The particular specification of polyethylene (food grade quality)
which TEK-TANKS use will not corrode and provides clean, taste
free water for the galley.
INSPECTION HATCHES 
These are high quality proprietary hatches with a large O ring
seal. Where height is a problem then a 10mm thick hatch cover
with a rubber neoprene seal would be used. All hatches can be
supplied as an optional extra. Where cross baffles are adjacent
to an inspection hatch, the baffles have on average eight inch
diameter cut-outs to facilitate cleaning and maintenance.
PRESSURE TESTING FOR RELIABILITY
As part of our commitment to quality and reliability, every TEK-TANK
water tank, (built from 10 - 12 mm Polyethylene), is pressure
tested to 4 p.s.i. ( 8' hydraulic head)
