The many county engineers and painting contractors have found it a problem having suburban areas expands. In the rural areas, the county commissioners and zoning officials before would put the water tanks away from schools and houses. With the growing population, many water tanks are now surrounded by residential neighborhoods, causing changes in the method of repainting and maintaining water tanks. 1988 was the year that the assistant chief, facility design of the Bureau of Engineering for the Department of Public Works of Anne Arundel County in Maryland had the same problem. Near homes and a school with a playground was where this elevated water storage tank was located that even has a lead based paint job. The place that the tank was made in was far from people the engineer said. With many children in the place made them decided against open abrasive blasting that could cause airborne paint particles. Instead they looked into more ways to maintain the tank. It was ordered by the Department of Public Works that that surface of the tanks would be power washed, followed by an application of DTM or direct to metal enamel. The selection of the paint job was based on its ability to provide good adhesion without lifting the previous coating, good corrosion resistance, long term flexibility, and good gloss and color retention. The enamel is still protecting the tank as years went by, and the coating procedures in Anne Arundel County have changed. The containment procedures have becomes more advanced since it now permits people to use abrasive materials to either bare metal or remove the original prime coat without releasing paint particles into the atmosphere. Here, the previous coating was removed down to the original primer, and in some cases down to the bare metal and this is what they did in terms of proper containment procedure. The previous coating was actually seen to have been harm free but we contained the paint using tarps and ground cover to avoid inconvenience to residents. In the system there were also surface tolerant sealants and adhesives. Based on its adhesion and corrosion resistance properties plus its excellent surface wetting qualities the primer was chosen. In choosing the intermediate coat, chemical and moisture resistance is needed in a high build coating system. Just as well it provides a chemical and moisture barrier, and also can be top coated in just 18 hours to 14 days. The best temperature to apply the primer and the intermediate coat is at temperatures between 35 degrees F and 120 degrees F at 85 percent relative humidity. This allowed the painting job to continue even if weather conditions were not perfect and when other coatings could not be applied. It was due to its performance and aesthetic qualities that the top coat was chosen. The coatings have different colors so that each part was sure to be coated. When it came to the primer beige was chosen. Medium blue was assigned to the top coat while, light blue to the intermediate coat. In sum around 37,000 sq.ft was coated.
