A life cycle costing analysis (LCCA) is the process of compiling cost estimates for each coating system option in combination with the expected life span of each of those options. In general terms, the lowest cost per year of service is the most economical choice. This LCCA process can be paired with an environmental impact analysis to evaluate the sustainability considerations of managing the water tank asset. One of the most commonly addressed factors in an environment life cycle assessment is a calculation of the greenhouse gas emissions associated with a process, presented in equivalent CO2 emissions.

Selection and management of coating systems for the interior and/or exterior of a water tank is no easy feat. Owners must consider different factors including cost, lifecycle, and environmental impact when making decisions about coatings.


The process of selecting a coating system and maintenance plan for a steel water tank is often based solely on personal opinions about the proposed system’s value. These opinions can be limited in scope and hard to verify with data. In recent years, the industry has recognized life cycle costing (LCC) as a method of decision-making for owners and engineers to determine the most economical and sustainable solution for their asset in terms of corrosion protection.


AWWA D102-21, Coating Steel Water-Storage Tanks, recommends the aid of an economic review using a life cycle costing analysis (LCCA) to determine the best suited course of action for coating and maintaining a steel welded water tank.


A collection of multiple industry papers and resources, including the recently published paper “Separating Fact from Fiction – AWWA D102 Coating Service Life” provide unbiased historical data on which coating service life and costing can be extrapolated. Using these resources, an accurate life cycle analysis (LCA) can be completed for any water tank asset.
After reading this paper, the reader will have a general understanding of where to locate accurate resources for critical inputs on water tanks, the life cycle costing and environmental analysis process, and how to use a life cycle analysis as a tool for asset management.

Theory and testing of composite materials on Stress Corrosion Cracking

Stress Corrosion Cracking, or SCC, is part of a group of cracks commonly known as Environmental Cracking. Additional types of cracks found in this group include corrosion fatigue and hydrogen embrittlement. It is generally known that SCC requires three factors to be present to form and continue growing. The first is a susceptible material. In the world of pipelines, carbon steel is quite susceptible to corrosion when buried but is typically protected from this threat utilizing a combination of external coatings in cathodic protection.

Stainless steels have been used for a wide range of applications in seawater. They are known to be susceptible to localized corrosion under given conditions. This is often the limiting factor for the use of stainless steels for seawater applications.

Evaluation of Mechanistic Models and Correlations for Predicting Solid Particle-Induced Erosion under Various Flow Regimes

Erosion, a mechanical process during which material is removed from the pipelines and other flow-containing equipment, can occur when solid particles such as sand are carried by the flow. Erosion is more critical when there is a change in the flow direction, such as particle-laden flows in elbows and tees.


While experimentation is a possible approach to obtain erosion rates, the conditions under which tests could be performed are limited in some respects.
