FRP Tanks and GRP Pipe Systems for Water Treatment Plants in Nigeria
Water treatment plants cannot afford contaminated storage or corroding pipework. Karoch Engineering supplies the FRP tanks and GRP pipe systems that keep treated water clean from storage through to distribution — across Nigeria.
When Your Storage Tank Corrodes, the Water Quality Problem Starts
Steel tanks corrode from the inside out. In water treatment environments — where pH adjustment, chlorination, and biological treatment chemicals are present — the rate of internal corrosion is accelerated. The result is iron particles, biofilm harboured in pits, and chemical contamination of treated water that has been through an expensive purification process.
FRP/GRP storage tanks have no iron to corrode, no coating to delaminate, and no pits to harbour bacteria. For water treatment plant operators, this is not a marginal improvement — it is the difference between maintaining treated water quality and failing the standards it was treated to meet.

What Makes FRP the Standard Choice for Water Treatment Storage
▸ Food-grade resin options — NSF-61 and food-grade isophthalic polyester for potable water contact
▸ No internal coating — eliminates the contamination and maintenance risk of coated steel
▸ Chemical-resistant liner — stands up to chlorinated water, pH-adjusted streams, and dosing chemical spillage
▸ Hygienic smooth bore — GRP pipes resist biofilm and scaling better than steel or concrete
▸ Flexible capacity — sectional panel tanks can be expanded as plant throughput increases
▸ Faster commissioning — panel tank assembly in 1–3 days versus weeks for welded steel alternatives

FAQ
Water Treatment FRP Questions — What Our Clients Ask
Do FRP tanks meet Nigerian NAFDAC or SON standards for water storage?
A: FRP tanks supplied by Karoch Engineering are designed to international standards including BS 7491 and comply with food-grade resin specifications for potable water contact. We recommend confirming regulatory requirements with the relevant Nigerian authority for your specific project.
Can one FRP sectional tank replace an old concrete reservoir?
A: In many cases, yes. A GRP sectional panel tank can be installed adjacent to or on top of a decommissioned concrete reservoir, providing a clean replacement without demolition. The FRP tank eliminates the ongoing problem of concrete cracking, algae growth, and contamination risk.
What is the minimum order for water treatment FRP tanks?
A: We supply single tanks from 500 litres upward. There is no minimum order. Contact us with your capacity requirement and plant layout and we will provide a quotation.
