Forty years of expertise in supplying California with galvanized water storage tanks

–A-1 Tank, LLC, located in Paso Robles, has been supplying high-quality customized galvanized water storage tanks for California since 1984. The tanks, in sizes from 1000 to 20,000 gallons, serve a wide range of purposes from drinking water for families and livestock, agriculture, and fire suppression. A-1 tanks are delivered throughout California, from the northern border with Oregon to the arid Central and Imperial valleys. As a leading water storage tank manufacturer for four decades, the A-1 Tank team has responded to a wide range of questions about their tanks and water storage tanks in general. They have condensed the most commonly asked questions and share them here.
- Are California residents required to have a water storage tank? California and local laws require a water supply that provides a water flow sufficient for fire suppression. If you are on a public fire hydrant system, you may not need additional fire suppression capabilities. If you live in a rural area, you most likely need a water storage tank for fire suppression. Additionally, at least one water tank needs to be easily accessible to fire crews, and it must be equipped with a valve so they can attach a hose. Check with your local fire authorities for details.
- Are galvanized water storage tanks effective for firefighting? Yes. The ability to store extra water for firefighting is a critical tool for assisting firefighters in getting fires under control and for extra time for families and neighbors to get to safety. Galvanized water storage tanks that are strategically placed in forests, wildlands, and rural areas are effective in providing water to fight fires. Unlike water storage tanks made of plastic, A-1 Tank’s galvanized water storage tanks are manufactured to withstand intense heat. Galvanized water storage tanks are located in national and state parks by the US Forest Service and the California Department of Forestry and Fire Protection (Cal Fire) to help fight wildfires throughout California.
- Can you deliver a water storage tank to a remote area? Yes. We deliver anywhere in California. The A-1 Tank custom-built 4-wheel drive delivery truck hauls 15,000-gallon tanks anywhere, including over rough terrain. Tanks are unloaded and positioned hydraulically.
- Are galvanized water storage tanks suitable for drinking water? Yes. Galvanized water storage tanks are safe for drinking water, especially when the interiors are coated with a special epoxy coating that is certified by the National Sanitation Foundation. The epoxy coating used by A-1 Tank is certified in accordance with the ANSI/NSF Standard for potable water.
- How do I know what size tank I need? A-1 Tank staff works closely with you to make sure the tank meets your needs.
- How long does a galvanized water storage tank last? Galvanized water storage tanks have a lifespan of 50 or more years, at least 30 years longer than the 10 to 20-year lifespan of plastic tanks. Galvanized water storage tanks are durable and built to withstand harsh environmental conditions, including rust and high temperatures.
