What Kinds of Information on Field Erected Storage Tanks is Available? ASK DOC
The members of the STI/SPFA Field Erected Storage Tank Section build steel water tanks that meet or exceed the requirements of AWWA, NSF and industry standards.  Click here to view a list of Related Water Industry Websites.			The Total Cost of Ownership Program Tool provides real-world data on fabrication, inspection, maintenance, touch-up and repair costs for steel tanks versus other materials. Scenarios enable the buyer to compare “apples to apples”, and reflect the real costs for different materials over their entire life cycles.
Tanks can be designed to hold from 50,000 to several million gallons and are provided with foundations and often finished with elaborate, painted graphics and color schemes. Tanks may  incorporate cathodic protection and piping. Some water tank designs allow for several floors, office space and other facilities. Private, municipal and various industrial water system engineers and operators specify steel tanks for their reliability, long-term value, and their low, predictable normal maintenance.

STEEL WATER STORAGE TANKS: DESIGN, CONSTRUCTION, MAINTENANCE, AND REPAIR The design, construction, operation and repair of steel tanks for potable water storage are the topics covered in this engineering reference handbook. It covers all types of steel water tanks, both ground-supported and elevated. Chapters cover tank configurations, location, appurtenances, codes and regulations, corrosion control, foundation, welded tanks, bolted tanks, operation, maintenance, inspection, cleaning, rehabilitation, repair, and security. Author Stephen W. Meier, PE, SE, Chair of AWWA's Steel Tank Committee, is one of the foremost experts on concrete and steel structures for water storage.

Tank Seminars
Annually, STI/SPFA hosts One-Day Water Tank Seminars  at which seven industry professionals present a program that earns 8 PDH's (Professional Development Hours). The seminar includes an examination of how to use and interpret water tank standards, a review of the substantial 2005 changes to AWWA Standards,Spotsylvania reckless driving, seismic designs and selection considerations, impressed current and galvanic (sacrificial) anode cathodic protection systems, lower VOC coatings, and using an accurate Life Cycle Analysis to determine the best tank for your needs.                                                                                              

ANNUAL TANK OF THE YEAR AWARDS
Each year, STI/SPFA acknowledges member companies with Tank of the Year Awards in all categories to recognize tanks that best represent the advantages and flexibility of steel construction. Below are some examples of Tank of the Year Award Winners and more can be viewed here.

CATEGORIES OF STEEL WATER TANKS
Members of STI/SPFA produce common types of water tanks in the categories: elevated, reservoir, standpipe and special storage system products.

Elevated Water Tanks are often called water towers. An elevated water tank is a simple way to store water and provide pressure in the water distribution system. Elevating the water tank creates a system distribution pressure at the tank outlet of 1 psi per 2.31 feet of elevation; thus a tank elevated to 70 feet creates about 30 psi of discharge pressure. The 30 psi is sufficient for most applications. There are various type of elevated water tank designs.

Multi-Column (Leg Type): The tank is elevated by a series of steel columns around its perimeter. This is one of the oldest Tampa car accident lawyer tank style types. This multi-column design was common in years past but has been replaced in recent years with less expensive designs. STI/SPFA Century Club honors water tanks that have been in continuous service for 100 years or more. The multi-column, leg type elevated tank design is common among the Century Club members, as is the Standpipe design, described below. To view a list and photographs of the Century Club honorees, please visit STI/SPFA Century Club here.
Flared Steel Column (Golf Ball and Tee) This is probably among the most common and most recognizable designs for water tanks. These tanks can hold approximately 2 million gallons of water. Many such tanks are designed with elaborate exterior colors and graphics representive of the facilities and communities the tanks serve. As the collection of photos here demonstrates, the shapes of the tanks can be just as varied as their surface appearance.
Fluted Steel Column (Hydropillar) These common tanks are supported by a large diameter fluted steel column. One attractive pos system feature about this type of tank is that the space inside the pillar can be used for offices, meeting rooms, or for equip-ment and machinery storage. The pillar also provides sufficient space for multiple floors.	Standpipes comprise another category of water tanks that  creates pressure in a water supply system. For a tall building,  for instance, where the pressure from water mains at street level  is insufficient to raise the water to upper floors, water is pumped  up to a standpipe and fed by gravity into the system.
