FRP Water and Wastewater Systems Engineered for Demanding Water
From raw-water intake to compliant discharge, Tosun Tech supplies FRP water and wastewater systems built for corrosive water chemistry — including storage tanks, piping, process vessels, odor-control scrubbers and liners — matched precisely to your water analysis and BOM. We replace crack-prone concrete, rusting steel and softening commodity plastic with fiberglass-and-resin composites that stay light, strong and nearly maintenance-free across decades of service. For the basic properties of the material, see the Fiber-reinforced plastic article. With Tosun, your FRP water and wastewater systems rest on field-proven designs.
In this article
FRP Tanks & Process Vessels
Filament-wound or hand-layup shells with corrosion liners for raw water, clarified water, sludge and dosing — resistant to acids, alkalis and salt spray.
PP Process Vessels
Homopolymer and copolymer polypropylene vessels for electronic-grade pure water, pickling lines and mixed-acid industrial wastewater.
Scrubbers & Ducting
FRP/PP wash towers, demisters, fans and ducts that remove H₂S, NH₃ and VOC from headworks and sludge handling.
Geosynthetic Liners
HDPE/LLDPE geomembranes and GCL composite pads for equalization basins, leachate lagoons and emergency berms.
Why Choose Tosun Tech’s FRP Water and Wastewater Systems
Tosun Tech delivers more than equipment — a complete engineering partnership that lowers your risk, shortens the schedule and gets plants into operation faster. Learn about the company and certifications on the About Tosun Tech page. Our FRP water and wastewater systems have been running steadily in multiple coastal and industrial projects.
- Resin matched to chemistry: vinyl ester for strong oxidizers, unsaturated polyester for neutral salts, PP for strong alkali and fluoride — never one resin for the whole plant
- Lightweight and fast to install: FRP weighs about one-quarter of steel, so smaller cranes, less civil work and faster site completion
- Long life, maintenance-free: no painting, no cathodic protection, no annual recoating — most tanks run 25+ years
- Custom to your BOM: send the P&ID, water analysis and design code, and we deliver drawings and certificates against the real load case
- One supplier, one warranty: storage, transfer and treatment come from a single Tosun BOM, keeping tank and pipe on the same resin system

Frequently Asked Questions
Which resin do you recommend for FRP tanks in chemical service?
For oxidizing media (sodium hypochlorite, chlorine dioxide, hot acid) we default to vinyl ester with a C-glass surfacing veil; for neutral salt, alum or lime storage, isophthalic unsaturated polyester is sufficient. We always benchmark against your water analysis before sign-off.
Can materials be selected to match our water chemistry?
Yes. Send the full ionic profile, operating temperature and duty (continuous/intermittent), and our process team returns a written resin recommendation with corrosion-allowance notes within five working days.
What is the typical lead time for a custom FRP tank?
A standard 50 m³ tank ships 6–8 weeks after drawing approval; large vessels with internals, agitators or instrumentation take 10–14 weeks. Expedited lay-up schedules are available on request.
Do you provide on-site installation supervision?
Yes. Tosun supervisors attend lifting, alignment, flange connection and final hydrostatic testing alongside your contractor, and we run a 3-day installation course at the factory.
Which standards do your FRP tanks comply with?
We design by default to BS EN 13121 (GRP tanks and vessels), with ASTM D3299 / D4097 on request; welded PP vessels follow DVS 2205 and ASME BPVC Section X; geomembranes meet GRI-GM13 / GRI-GC4.
