Special Features
- Typically, Ground Storage Tanks are the most economical way to provide simple, long-term water storage, if the added pressure from an elevated water storage tank is not needed at a given tank site.
- Tank diameters and heights are varied to meet customer requirements.
- Ornamental pilasters or other architectural treatments can be added for a unique and beautiful structure.
When It's Best
- Welded steel ground storage tanks are low cost, flexible in a seismic event or foundation settlement, and can easily be modified or retrofitted
- Quickest style to construct and works well at higher ground elevations
- Standpipe designs can achieve additional pressure in the water system (especially for power outages)
- Reservoir designs can increase storage capacity in the water system (especially for fire protection)
Highlights & Advantages
- Smaller ground storage tanks are easier to disguise (which is harder to find); and can easily be painted with specialty designs and attractive logos
- Epoxy and polyurethane coatings provide long life and require very little maintenance
- Four different styles of typical roofs: Ellipsoidal, Sphericone, Dome, Low Pitched Cone
Standard Sizes
- Normal capacity ranges are from 25,000 to 8,000,000 gallons with endless dimensional possibilities
