In early 2009 the City of Sunnyvale in Northern California put out to bid a repaint of three five‐million gallon water tank exteriors. The tanks existing coatings qualified as leadbased paint with average concentrations of 120,000ppm or 12% lead. The three tanks were successfully abrasive blasted to an SSPC SP‐10 and recoated with a zinc/acrylic system without erection of an SSPC Guide 6 Type 1A enshrouding containment. This paper tells the story of how this was done successfully using standard but not often seen work practices, even though the project was right next door to an elementary school and multi‐family residential developments and so had to perform to the strictest levels of environmental standards.
California Water Service (Cal Water) has had a team dedicated to the maintenance of its water tank infrastructure since the 1970s. The Team faces significant challenges as it strives to maintain the reliability of more than 450 water tanks throughout the State of California. Some of these challenges include tighter State regulations, increased visibility from the public, limited resources, aging infrastructure, and an aging workforce that will take their valuable institutional knowledge into retirement with them.
In this article, we will be presenting some background about the zinc‐in‐immersion technology itself while addressing some of the important questions where the two opposing sides commonly clash. A discussion over failure modes; reasons for failure; and alternate technologies will be discussed. Additional information will detail what factors and features are needed to develop a good lining to protect steel water tanks. The paper will conclude by discussing alternative coating options that exist (including “greener” versions) and expected performance levels these coatings are anticipated to provide.
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.
Saline Water Conversion Corporation (SWCC) is the largest producer of water by its different water desalination plants distributed around the kingdom. In SWCC above storage tanks (ASTs) have the capacity to store 140,000 m3 of produced water. Most tanks are commissioned more than 20 years and have worked properly with minor observations on their performance. Mostly SWCC tanks are made of carbon steel and internally protected with a two - components epoxy coating as a passive method and cathodic protection as an active method.
Over the years, construction of telecommunication sites on municipal buildings and water storage facilities have become commonplace. Installations and upgrades of telecommunication sites, from the planning phase to activation, can extend over multiple years creating an unpredictable construction season. Careful planning with extreme ambient conditions on either side of the spectrum has become a standard in the industry.
In 1984 the US EPA issued a Request for Proposals to select a provider to privatize the approval of products and components used in water distribution systems across the United States. A team which was led by NSF International and included the American Water Works Association Research Foundation, the Association of State Drinking Water Administrators, the Conference of State Health and Environmental Managers, and the American Water Works Association was awarded the contract to develop the standard. In 1988, NSF/ANSI 61: Drinking Water System Components ― Health Effects was published as a result of the work of this team. This standard established minimum requirements for the control of potential adverse human health effects from products that contact drinking water and has been updated regularly since then to add testing criteria for additional contaminants and product types.
