One of STI/SPFA’s goals with our expert’s design tips is to point out important changes in the new edition of AWWA M11 and to provide background of why such revisions were made. Steel pipe systems have been designed, fabricated, and installed with decades of experience, achieving reliable and long-lasting operational service, while establishing proven safety factors that the engineering community has trusted. Steel pipe manufactured to AWWA standards are usually considered an engineered product and require a certain amount of engineering input to be functional for a water facility. This article will review Good Engineering Practice and how some design criteria has evolved from Good Engineering Practice.

LAKE ZURICH, IL, Jan. 24, 2019 - Winners were announced last week for the 2018 Steel Water Pipe Product Awards. The announcement took place during the Steel Water Pipe Section meeting in South Carolina. Member companies in three product categories were recognized. (Entries are for products fabricated in the prior year.)
Job Title: Standards Engineer
The person in this position will work mainly with STI’s shop fabricated tank section. Much of the work will be done independently, but with collaboration from STI’s technical committee.

The 5th edition of AWWA M11 has been available for a little over a year and the benefits to engineers have been recognized for the value it has for steel pipe design. There were numerous changes and additions that are intended to clarify important design criteria when designing steel water pipe.
The nature of engineering design is that the knowledge used to design large facilities is learned and remembered mostly during the work on a project. This series of articles will highlight many of the major changes in the new AWWA M11.
The first article in a series will concentrate on outlets in a pipeline. This article, along with the remaining articles, will become useful references for the design of pipeline and treatment plant projects.
How does water get into your underground storage tank?
All storage tank systems, both underground and aboveground, constructed of any material, and storing nearly any product—gasoline, diesel, residential and commercial heating oils, aviation jet fuel, and others—are susceptible to damage if water is allowed to accumulate. The potential for damage applies not only to the tank, but also to the entire storage system.
Today’s fuels are more susceptible to moisture separation and accumulation. Also, removing lead from gasoline and sulfur from diesel has had the side effect of allowing microbial growth to occur more readily, since lead and sulfur inhibit microbial activity.
Ethanol and biodiesel are important in today’s fueling network. But allowing water to remain in these storage systems can cause fuel separation, fuel degradation, and non-metallic equipment compatibility concerns.
For all these reasons, it’s more important than ever to conduct regular inspection and maintenance of your entire UST or AST fuel storage system.
INSTRUCTIONS
Download STI-SPFA’s handy new tank maintenance brochures. Using copier to print brochure, set paper size to 8 1/5 x 14 (legal), UNcheck "Fit to Page," check "Print Two-sided," and fold printed brochure in half twice (four panels).
STI-SPFA's Total Cost of Ownership (TCO) web-based tool provides real-world data on fabrication, inspection, maintenance, touch-up, and repair costs for steel tanks versus other materials. Users can also input their own data, allowing "apples-to-apples" comparisons that reflect the real costs for differing materials over their entire life cycles.
The TCO cost analysis tool assists you in analyzing the total cost of ownership of three common types of flat-bottom, ground supported water storage tanks (with roofs) constructed in accordance with AWWA standards:
Access to the TCO tool is complimentary for all users, but you must register.
Then you can input and store data related to your tank or tank project, and/or study the default data presented in the program. There is no limit to the number of tank projects you can store here. Your data is retained for one year and is secure, only available to you.
