Westeel WaterTank Flat Roof, Installation And Storage Instructions

Page: 5 / 23

DISCLAIMERS
Method of Erection
The recommendations for erecting Westeel Water Tanks should be closely followed to
achieve the full strength of the tank and to achieve adequate weather sealing. Warranty is
void if the recommendations are not followed including but not limited to:
1. Wall sheets which are not specified for a given tier, are used.
2. Foundations are found to be inadequate or out-of-level.
3. Anchor bolts (cast-in-place, drill-in, chemical type or other) are found to be
inadequate.
If using Bin Jacks: Choose a hoist with a suitable capacity for the expected empty tank
deadload. Make sure the rated capacity of the hoist is not exceeded.
Design
Standard Westeel Water Tanks are designed for, unless otherwise requested and specified
in writing from Westeel:
1. Containment of liquids with a specific gravity of less than or equal to 1.0.
2. Maximum horizontal gusted wind speed of 94 mph (151 km/h)
3. Zero seismic activity. (Note: Seismic resistance in grain bins varies with height
and diameter. Many standard designs have significant seismic capabilities.
Designs can be reviewed and/or modified to reflect local seismic requirements.)
4. Little to no roof snow load was considered in the design of the water tank flat
roofs.
Site and Assembly
Unless otherwise specifically provided in writing, Westeel does not take responsibility for
any defects or damages to any property, or injury to any persons, arising from or related to
any site or assembly considerations, including but not limited to:
•
Tank location and containment system siting;
•
Soil conditions and corresponding foundation requirements (note that the
examples provided in manuals are for specifically stated soil conditions);
•
Tank assembly
•
Field modifications or equipment additions that affect the tank structure,
unless supplied by Westeel and specified for the specific application;
•
Interconnections with neighbouring structures.
•
Compliance with all applicable safety standards, including but not limited to
fall restraint systems (ladders or other systems). Local safety authorities
should be contacted as standards vary between jurisdictions.
