WATER TANK LINERS

Is your water tank safe after a storm or natural disaster?

carsonliners · May 5, 2025 ·

After California’s recent wave of extreme weather events, ranging from atmospheric rivers to devastating floods, water tank maintenance and cleaning has become a top priority for homeowners, agricultural producers and facility managers.

Carson Liners understands that natural disasters can significantly impact water storage systems, leading to contamination, structural damage and costly disruptions in service. Proper tank maintenance is not just about ensuring clean water, it’s about preserving system integrity, reducing long-term costs and keeping water infrastructure resilient during crisis.

When the skies clear, one critical question remains: is your water still safe to use, store, or drink?


How environmental disasters impact water tanks in California

In February 2025, California experienced intense atmospheric river events, bringing substantial rainfall across the state. These storms resulted in heavy precipitation, which led to record-breaking flooding and concerns over water contamination. The National Weather Service issued warnings for difficult travel conditions and potential flooding in areas recently affected by wildfires, where debris flows became a significant risk.

The intense rainfall overwhelmed stormwater systems and rapidly filled reservoirs, but it also posed challenges for water tanks, especially in flood-prone or rural areas. Tanks positioned in low-lying zones were at risk of submersion or damage from fast-moving floodwaters. In some instances, access roads to tank sites were washed out, making maintenance or emergency response more difficult.

Risks to water tanks during floods include:

  1. Flood-related structural damage to tank foundations, walls and access points
    Floodwaters can weaken or erode tank foundations, crack structural walls and damage access hatches, putting the entire water storage system at risk.
  2. Contaminated runoff entering tanks through improperly sealed lids or damaged inlets
    Improperly sealed tank lids or broken inlets allow polluted runoff from storms to enter the system, introducing bacteria, chemicals and sediment into the stored water.
  3. Debris from roads, fields or wildfire zones entering the water supplies
    Debris carried by stormwater, such as mud, ash, and chemical residue, can infiltrate unprotected tanks, severely contaminating agricultural and potable water supplies.
  4. Loss of access to remote tanks due to washed-out roads and hazardous conditions
    Washed-out roads and unstable terrain following a disaster can prevent timely inspections and repairs of remote water tanks, increasing the risk of prolonged outages or contamination.

Our team of experts recommends post-flood tank inspections and cleaning as an essential step toward ensuring your water remains safe and compliant. Our tank liners provide an extra layer of protection, especially for tanks exposed to unpredictable environmental conditions.


Debris flows in wildfire burn scar zones

In California’s mountainous and foothill regions, areas previously scorched by wildfires face a significantly elevated risk of debris flows especially during intense storms. These zones, known as burn scars, are highly unstable and vulnerable to rapid erosion when saturated by rain. The vegetation that once stabilized soil and absorbed rainfall has been destroyed, leaving behind loose, hydrophobic soils that can’t easily absorb water.

Carson Liners works closely with landowners in wildfire-prone areas to offer disaster-resilient solutions for tank protection.


What happens during a debris flow?

Debris flows are fast-moving, destructive torrents of water mixed with mud, rocks, vegetation and other materials. Unlike normal flooding, debris flows have enough force to destroy infrastructure, block access roads and sweep away anything in their path, including water tanks. In post-wildfire environments, even moderate rainfall can trigger these flows due to the destabilized terrain.

Water tanks located downhill or within proximity to burn scars are particularly at risk. The threats include:

  1. Foundation displacement or soil erosion, which can unseat or damage tanks
    The sheer force of debris flows can erode or undercut the soil beneath water tanks, dislodging them from their foundation or causing tilting and cracking.
  2. Broken fittings and plumbing systems caused by moving debris
    Flowing debris can break or clog exposed plumbing connections, making the tank unusable until extensive repairs are made.
  3. Burying or complete submersion of tanks and underground pipelines
    Entire tanks or pipelines can become partially or fully buried under feet of mud and debris, requiring excavation and specialized recovery efforts.
  4. Delayed repairs and inspections due to road blockages or unsafe conditions
    Washed-out roads and unstable terrain can delay inspections, repairs and emergency water delivery to affected communities or agricultural sites.
  5. Heat damage from wildfires compromising concrete tank structures
    In addition to debris threats, extreme heat from a wildfire can cause cracking in concrete water tanks. This thermal damage weakens the tank’s structural integrity, making it more vulnerable to leaks, contamination, and eventual failure—even before storms or debris flows arrive.

To mitigate these threats, Carson Liners offers customizable tank liner systems and consulting for communities in high-risk debris flow zones. Our liners can help extend tank life and reduce the risk of contamination following a storm.


Coastal erosion and its implications for water tank infrastructure in California

Coastal regions in California are increasingly contending with the long-term impacts of sea-level rise and coastal erosion. Projections show that a sea-level rise could place much of Southern California’s beachfront at risk, altering not only the landscape but also affecting the infrastructure that communities rely on, including water storage systems.

For water tanks located near coastal zones, these environmental changes present several important considerations:

  1. Shifting soils and unstable foundations due to coastal erosion
    As coastal erosion gradually wears away shorelines, water tank foundations may be exposed to shifting soil conditions, increased groundwater levels and saltwater intrusion. These changes can compromise the structural stability of both above-ground and below-ground tanks, increasing the risk of leaks or collapse without proactive reinforcement.
  2. Saltwater corrosion affecting metal tank components and plumbing
    Rising sea levels and storm surges can introduce higher levels of salt into the surrounding soil and air, accelerating corrosion on metallic components of water storage systems, such as tank walls, pipes, and fittings. Even tanks made with corrosion-resistant coatings may require more frequent inspection and maintenance in these changing conditions.
  3. Restricted site access following storm surges or shoreline degradation
    Erosion of coastal roads and properties can hinder access to water tank sites, especially during or after extreme weather events. This may delay critical inspections, maintenance or emergency repairs, underscoring the need for resilient site design and backup infrastructure planning.
  4. Compliance with new environmental regulations requiring setbacks or tank relocations
    As coastal management policies evolve to address erosion and flooding risks, water tank projects may be subject to new regulations, setback requirements, or relocation mandates, particularly for tanks positioned near at-risk zones. Adapting early to these changes can save both time and cost in the long run.

These events underscore the need for proactive measures to enhance the resilience of California’s water infrastructure against natural disasters.

Carson Liners provides geomembrane tank liners specifically designed for coastal environments. These liners serve as a protective barrier between stored water and the harsh effects of salt exposure, helping water facilities stay compliant, resilient and ready for changing coastlines.


Other ways natural disasters affect water tank systems

California’s diverse geography makes it uniquely susceptible to a range of natural disasters, including earthquakes, wildfires, floods and coastal erosion that can damage or contaminate water storage systems in several ways:


The hidden dangers of sediment infiltration during storms

When storms strike, your water tank may be more vulnerable than you think. Heavy rainfall and flooding don’t just bring rising water, they also carry a toxic mix of sediment, organic matter and chemical pollutants. If your tank’s seals, filters, or overflow systems are compromised, this runoff can infiltrate the tank, degrading water quality and introducing contaminants that clog filters, damage pumps or make water unsafe for consumption. Understanding the risks of sediment infiltration is the first step in protecting your water infrastructure and ensuring long-term water safety, especially in storm-prone regions like California.

  1. Contaminated stormwater can enter unsealed tanks
    Heavy rainfall and flooding carry sediment, debris, and pollutants that easily infiltrate tanks through compromised seals, filters, or overflow systems.
  2. Clogged filters and intake screens
    Fine sediment can block filters and screens, reducing water quality and straining the system’s filtration capacity.
  3. Reduced water pressure and flow
    Sediment buildup in pipes and valves restricts flow, leading to inefficient water delivery and reduced pressure.
  4. Damage to pumps and mechanical components
    Abrasive particles can wear down pump systems and clog moving parts, increasing the risk of mechanical failure.
  5. Sludge buildup at the bottom of the tank
    Settled sediment forms a sludge layer that promotes the growth of bacteria and algae, especially in warm conditions.
  6. Foul odors and water contamination
    Organic material in the sludge can release unpleasant odors and toxins, making water unsafe for drinking or irrigation.
  7. Interference with water treatment
    Sediment and biofilm can neutralize disinfectants and cling to tank surfaces, complicating water treatment and sanitation.
  8. Costly cleanup and water loss
    Severely contaminated tanks may require full drainage, intensive cleaning, and water disposal to restore safe use.
  9. Preventive protection with Carson Liners
    Carson Liners offers durable tank liners and sealing solutions to help prevent sediment infiltration and protect your water quality year-round.

Structural damage from seismic activity

Water tanks, whether installed above or below ground, are engineered to withstand a range of environmental conditions. However, the forces unleashed during natural disasters often exceed standard tolerances, leaving tanks vulnerable to serious structural issues that aren’t always immediately apparent.

California sits atop multiple active fault lines, making earthquakes a constant threat to water tank infrastructure. The state’s geology means that both residential and commercial tanks are routinely exposed to seismic activity that can compromise their structural integrity. While many tanks are designed with basic seismic resistance, ongoing tremors and aftershocks can cause long-term structural issues that aren’t always visible right away.

Potential seismic impacts on water tanks:

  1. Cracks or microfractures in tank walls, especially in older concrete or fiberglass models
    Seismic activity can cause small, often invisible cracks that lead to long-term leaks and water contamination.
  2. Shifting or tilting due to slab or pier foundation damage
    Ground movement can destabilize tank foundations, resulting in uneven load distribution and structural stress.
  3. Broken seals or connections in internal plumbing systems
    Even minor shifts can strain joints and seals, increasing the risk of leaks or system failure.
  4. Dislodged tanks from failed anchoring systems during severe shaking
    Inadequate or damaged anchors can cause tanks to shift, tip, or collapse entirely during earthquakes.

Carson Liners recommends post-earthquake tank inspections to detect early signs of damage and highlights the importance of high-quality liner fabrication. Our liners can help preserve water quality even when tanks develop small internal cracks or begin to leak, extending usability while structural repairs are underway.


Is your water still safe?

Floods, wildfires, earthquakes and erosion can quietly compromise your tank, affecting water quality, damaging infrastructure and costing you thousands in repairs. Yet many of these issues are invisible until it’s too late.

If your property has been affected, inspecting and cleaning your water tank isn’t just a precaution; it’s essential. Taking quick, proactive steps ensures your water remains safe, your system stays operational and costly damage is avoided down the line.

After the storm clears, don’t wait. Make water safety your next priority.

TANK REPAIR OR REPLACE?

carsonadmin · May 2, 2023 ·

Tanks are used for various purposes, including storage of water, fuel, and chemicals. However, over time, tanks may experience wear and tear that can lead to leaks, cracks, and other issues. When faced with a damaged tank, property owners must decide: should they repair the tank or replace it altogether? Or is there another affordable solution?

Damaged tanks can be a big issue and an especially serious issue for industries that rely on them for storing high-volume liquids or gases. Leaks and cracks can lead to product loss, environmental damage, and costly repairs. However, instead of replacing the entire tank, dropping in a liner can be a more beneficial and cost-effective solution. Liners can be made from various materials such as PVC and various types of high-grade polyurethane, and are designed to fit snugly inside the tank, creating a barrier between the stored product and the damaged tank walls.

There are pros and cons to either option, and the decision will ultimately depend on a variety of factors, including the size and type of tank, the extent of the damage, and the property owner’s budget and timeline

Damaged tanks: Are there other alternatives?

One of the main benefits of using a liner is that it can extend the life of the damaged tank. Liners are designed to be durable and resistant to chemicals, abrasion, and temperature changes, providing a long-lasting solution to tank damage. Additionally, liners can be customized to fit any size or shape of the tank, meaning that tanks of any age or design can be repaired with this method. This can save companies a significant amount of money, as replacing a damaged tank can be a costly endeavor.

Dropping in a liner can be a quicker solution than replacing a damaged tank. Liners can be installed in a matter of days, depending on the size of the tank, whereas replacing a tank can take weeks or even months. This means that industries can quickly resume their operations without experiencing prolonged downtime. Overall, using a liner to repair a damaged tank can be a cost-effective, durable, and efficient solution that benefits both the environment and the bottom line of a business.

When to replace a tank

Repairing a tank is not always the best choice. Depending on the extent of the damage, repairing a tank may only be a temporary fix, and the tank may experience additional issues down the line. Additionally, depending on the size of the tank and the nature of the damage, permits may be required to complete the repairs, which can add time and cost to the process. The tank may require excavation and removal of the old tank, which can be time-consuming and expensive. Additionally, the sentimental or historical value may be attached to certain types of tanks, such as Redwood tanks, which may make it difficult to justify replacement. Yes, replacing a tank may be necessary if the existing tank no longer meets local regulations or safety standards.

However, replacing a damaged tank may be the best option, especially if the tank is older, larger, or structurally compromised. By replacing the tank, property owners can ensure they have a new, fully functional tank that is less likely to experience issues in the future.

Depending on the type and size of the tank, permits may be required to complete the replacement process, which can add time and cost to the project.

What to consider when a tank needs maintenance

Size of the tanks

The size of the tank is a key factor in determining whether to repair or replace it. In general, tanks that are smaller than 3,000 gallons are more cost-effective to replace than to repair, as the cost of repairs may outweigh the cost of replacement. Additionally, smaller tanks may not have the structural integrity to withstand repairs and may be more prone to additional damage down the line.

Permits

Depending on the size and location of the tank, permits may be required to complete repairs or replacements. Property owners should check with their local authorities to determine what permits are required and what the process will entail.

Structural Integrity

The structural integrity of the tank is also an important consideration. If the tank has extensive damage or is structurally compromised, repairs may not be possible or may only be a temporary fix. In these cases, replacing the tank may be necessary to ensure its safety and longevity of the tank.

Cost and Timeline

Finally, property owners must consider their budget and timeline when deciding whether to repair or replace a damaged tank. While repairing a tank may be less expensive in the short term, it may not be the most cost-effective option in the long run. Similarly, while replacing a tank may be necessary for safety or regulatory reasons, it may not be feasible for property owners with limited budgets or tight timelines.

SELECTING THE RIGHT MATERIAL

carsonadmin · March 23, 2023 ·

When it comes to lining a pond, the first and more popular option is a flexible liner made from Reinforced Polyethylene, Reinforced Polypropylene, CSPE, PVC or EPDM Rubber.  There are other cheaper materials available; however for the purpose of building a lasting pond, it is advisable to use one of these flexible materials.

Reinforced Polyethylene (RPE) Liners

Reinforced polyethylene liners are generally considered the most durable liners available. In many cases, RPE liners don’t require a protective underlayment because of their higher tensile strength. Another advantage of reinforced polyethylene is they can be produced in very large sizes because of their light weight.  However, a possible disadvantage to a RPE liner is that the material is slightly stiffer to work with which is only a problem if the pond has a lot of sharp protrusions, bends or corners or pipe penetrations.

Reinforced Polypropylene (RPP) Liners

Reinforced polypropylene liners are generally used for potable water applications.  RPP can be easily box-welded into 3D shapes.  Box-welding is the process of taking a flat liner and creating a 3D shaped box through the process of heat welding the seams. The main advantage of box-welding is that all the corners are nice and clean with no folds or wrinkles. If you’ve ever worked with a flat liner like EPDM rubber and tried to bend it around corners and ledges, you’ll know that you will never get it completely flat. RPP is the preferred material if a pond has pipe penetrations.  It also has an extremely long life-span.

Chlorosulfonated Polyethylene (CSPE) Liners

Chlorosulfonated Polyethylene liners are geomembranes formerly known as Hypalon. CSPE or HypaFlex is a high-performance material designed for long-term applications, including floating covers and exposed liners. CSPE provides truly outstanding UV protection and long-term performance. HypaFlex is backed with an industry-leading 30-year weathering warranty.

PVC Liners

PVC liners are usually the least expensive option compared to other flexible liner materials, but their biggest downside is their lack of UV stability. What that means is that the pond liner must be completely buried with no direct sunlight contact; otherwise, the liner will begin to break down, shortening the life span.

EPDM or Rubber Liners

EPDM rubber liners are quite heavy.  They are typically quite UV resistant which is a definite plus over some PVC liners. As a fishpond liner, EPDM is a good choice due to the lack of plasticizers in the liner. It is also possible to join two or more sheets together with some pond liner tape.  In the case of large pond liners, it is often essential to combine multiple sheets to create a liner in the desired shape and size. Because rubber is so much heavier than material mentioned above, it is often more difficult to find and ship large pieces of EPDM due to weight concerns. If you need a large piece, it might be better to go with an RPE liner since it’s stronger, lighter and more cost effective.
