Stainless Steel in Drinking Water Treatment
Stainless steels can provide corrosion resistance without the need for coatings -- even at very high flow
rates. This allows lightweight, cost-effective, and longlasting designs. Leaching of metals into the product
water is very low.
These topics are covered in more detail in the following publications:

1. 14030 - WATER TANK BUILT TO LAST 60 YEARS (1994)
By K. Kuwayama, reprinted from Nickel, Vol.10 (1), 1994. The city of Matsuyama on the Japanese island of
Shiboku has built the country's first stainless steel municipal water tank in order to ensure its residents a
safe, steady supply of drinking water well into the 21st Century. This article tells why they chose stainless
steel.

2. 10008 - NICKEL'S CONTRIBUTION TO DISTILLED WATER, DAMS AND CONDENSERS (1986)
By Arthur H. Tuthill, presented at symposium, the Metallurgical Society of the Canadian Institute of Mining
and Metallurgy (CIM) and Nickel Institute, Toronto, Aug 17-20, 1986; reprinted from CIM Proceedings, Nickel
Metallurgy, Series No. 25-7/6/1/3, Vol. 1, (2), 1986. Nickel alloys are used extensively in the production,
handling and treatment of high purity, natural and waste waters. The corrosion resistance of these alloys in
various waters is examined. Examples from nickel's contribution in applications ranging from hospitals
through large-scale dams, municipal treatment plants and power plants are provided.

3. 10016 - TEST TECHNIQUES FOR PITTING AND CREVICE CORROSION RESISTANCE OF STAINLESS STEELS AND
NICKEL-BASE ALLOYS IN CHLORIDE-CONTAINING ENVIRONMENTS (1987)
By Dr. John W. Oldfield, reprinted from International Materials Reviews, Vol. 32 (3), 1987. Test methods
currently available for determining the resistance of stainless steels and related alloys to pitting and
crevice corrosion in chloride environments are assessed. The present understanding of the mechanisms of
pitting and crevice corrosion are examined, and the major factors affecting the process are noted.
Accelerated and exposure test techniques are considered in relation to their ability to provide an accurate
ranking of materials, and to relate the service conditions.

4. 10085 - MICROBIOLOGICALLY INFLUENCED CORROSION OF STAINLESS STEELS BY WATER USED FOR COOLING
AND HYDROSTATIC TESTING (1998)
By G. Kobrin et al., originally presented at the 58th Annual International Water Conference, November 3-5,
1997, Pittsburgh, PA. Case histories from experience and the published literature illustrate factors which
resulted in microbiologically influenced corrosion (MIC) of stainless steel piping, storage tanks and heat
exchangers by waters used for hydrotesting, cooling and other purposes. Practices which will prevent or
reduce potential for MIC, including material substitution, are discussed, along with efforts to heighten
awareness of the problem.

6. 10087 - STAINLESS STEEL FOR POTABLE WATER TREATMENT PLANTS (1999)
By R.E. Avery, S. Lamb, C.A. Powell and A.H. Tuthill. Types 304L and 316L welded stainless steel piping has
been successfully used in over 100 PWTPs and related potable water applications in North America. The
principal reason to use stainless steel is its outstanding resistance to contaminate potable water with metal
ions. Stainless steel has been used since 1965 for the large, central-control, gravity filter in water
treatment plants with good performance in over 75 installations.

7. SCI P245 - STEEL PACKAGE WATER AND WASTE WATER TREATMENT UNITS (2000)
By N. R. Baddoo and A. R. Biddle. This publication addresses the use of steel and stainless steel package
units for water and waste water treatment. A package treatment unit is a module or series of linked modules
that is constructed in a factory and subsequently transported to a site for installation. Package units can
be assembled rapidly on site with the minimum of site works. A series of case studies of recent projects is
included to demonstrate the range of current applications of package units for different types of treatment
process, both on a large and small scale. Published by The Steel Construction Institute, 2000.

8. IGN 4-25-02 - APPLICATIONS FOR STAINLESS STEEL IN THE WATER INDUSTRY: WATER INDUSTRY
INFORMATION & GUIDANCE NOTE (1999)
The purpose of this publication is to help plant designers and operators to recognize those applications
where economic benefits can be realized from selecting an appropriate grade of stainless steel. Guidance is
also given on material selection for corrosion resistance, design of structural members, tanks and pipework
systems, fabrication and installation. Prepared by The Steel Construction Institute, in association with
Avesta Sheffield and the Nickel Institute, 1999.
