Liners used in stormwater capture systems need to be both UV and chemically resistant to ensure long-term durability and performance. Stormwater often contains a mix of organic matter, oils, and other urban pollutants that can degrade materials over time. A chemically resistant liner can withstand exposure to these substances without breaking down or leaching harmful compounds into the stored water.
UV resistance is equally important, especially for liners used in open ponds or reservoirs that are exposed to sunlight. Prolonged UV exposure can weaken some materials, leading to cracking, brittleness, and eventual failure. Liners made from reinforced polyethylene (RPE) are commonly chosen for their high resistance to both chemical exposure and ultraviolet radiation, making them well-suited for stormwater applications.
