Many different underground water tanks exist, for drinking water and much more. They are either installed as building updates or during the initial construction of the building. Sometimes water tanks are used during construction, while it is also essential to line them for protection of water stored underground. This prevents chemicals from seeping in from the soil. Additionally, protective liners differ between chemical tanks, where the groundwater is protected from the chemicals stored inside those tanks, and other tanks where it may be other toxins. One of the most common locations is the water tank liner that can safely protect against chemicals making their way into your drinking water.
Potable Water Tanks and Others
Potable water tanks are expansion tank vessels, small tanks used to protect closed water heating systems that are not open to atmospheric pressure. There are many other underground water tanks that store drinking water, domestic water, and filter water as well. Some tanks protect domestic hot water systems from excessive pressure, while most of these require any of a number of water tank linings, often certificated liners where water is contained for human consumption.
Water Storage Tank Liners
Various types of water storage tank liners often need to be certified in order to maintain the safety of those who may drink or even touch the water that is stored. Not always water for consumption, it has the potential to touch human hands and requires cleanliness of a certain amount for guaranteed health. Almost all water tanks are created from steel, even though potable water tanks are expansion tanks. Those made from steel or other metals mean that there is a need to protect the water systems that make their way into residential homes and commercial buildings from these tanks. Many other tanks, in addition to water systems, require special linings in order to help increase the life of these tanks and the service they will make for different companies. Some of the specific water storage tank liners that are included with these tanks include:
- Electroless nickel tank liners
- Custom tank liners
- Water trough liners
- Plating tank liners
- Industrial tank liners
- Concrete water tank liners
- Gas tank liners
- Potable water tank lining
The Need for Water Storage Tank Liners in Certain Locations
Some of these hold well over 1,000 gallons of fuel or other chemicals, and without the requirement of including water storage tank liners, companies or other properties that do not line their tanks could be at risk. An even longer list of chemicals and products exists for the requirement to all follow EPA regulations, which include these water storage tank liners included in the risk management plans that must be submitted to federal regulators.
Some liners are for tanks other than water, though most standards are developed for water storage tank liners. Other stored products, like gas or chemicals, must be prevented from soaking into the groundwater. Sometimes a surfacing, like chromium plating, may add to the chemicals that can soak into the water from a metal tank, requiring interior linings in those cases. While the many underground tanks that can hold water, chemicals, and fuel, they also require specific types of linings that can provide protection all around. Underground tanks last a long time, often at least 20 years, though the products they store may alter the lifespan. For that reason, linings can help keep up the life of water storage tanks in all locations.
