FRP replaces traditional materials in water systems through zero corrosion and extended service life. LEISA covers all 6 water sub-sectors.
Selecting a non-metallic piping system for this sector begins with the service envelope rather than a product name. Engineers should define the transported fluid, impurities, pressure and temperature cycles, external loads, installation environment, design life, joining method, and consequences of failure. Those conditions determine the resin system, reinforcement architecture, liner, qualification standards, and inspection stages. LEISA converts the resulting requirements into an inspection and test plan covering material identity, dimensions, short- and long-term mechanical performance, chemical compatibility, joint integrity, manufacturing records, and traceable acceptance evidence.
Potable Water
Inert, corrosion-resistant materials ensure 50+ year design life. Certification required per WRAS, NSF/ANSI 61, KIWA. LEISA provides leaching tests and material safety assessments.
Waste Water
H₂S chemical attack is the primary cause of network failure. FRP pipes are completely unaffected. LEISA performs ASTM D3681 strain corrosion testing.
Desalination
Seawater chlorine is highly corrosive. FRP pipes are completely chlorine-resistant. LEISA provides material chemical resistance testing.
Irrigation
Nearly 40% of global farmland faces water scarcity. Climate-resistant, lightweight FRP pipes reduce conveyance losses.
Storm Water
Extreme weather demands higher-capacity storm networks. Large-diameter FRP (up to DN4000) — the lightweight alternative to concrete/steel.
Water Treatment
Three distinct chemical environments — GRE/GRP/GRV materials can be tailored. LEISA provides material screening and qualification.
