What buyers said once the tank was on site — every review left on our Alibaba store, in their own words.
The food grade BDF tank from LVJIA is a bolted, buried storage tank pressed from bimetallic composite plate at our own plant in Dezhou, Shandong. It stores drinking water at municipal scale — 1000 cubic metres in one buried shell — with a contact report to prove the wetted surface.
A food grade BDF tank is a sectional tank assembled below ground from 1000 × 1000 mm pressed panels. Each panel is drawn in a single press stroke from a composite plate: a food-grade stainless layer on the face that meets the water, hot-dip galvanised steel behind it to carry the load. The panels bolt together inside the excavation, so no welding happens on site and no welded seam is ever in contact with the stored water. LVJIA builds this tank from 1 to 1,000+ m³, which means the volume follows the pit you have dug rather than a fixed catalogue size.
Three things, and none of them is a coating. The surface the water meets is a food-grade stainless layer bonded to galvanised steel and pressed in a single stroke, so there is no lining to blister and no paint to shed. No welded seam is in contact with the stored water, so there is no heat-affected zone where corrosion products can form. And the composite plate carries drinking-water contact report SP2630499 from the Dezhou Institute of Product Quality Standards and Metrology, which is the document a water authority or a plant auditor will ask to see.
Three things separate this food grade BDF tank from a coated steel tank. First, there is no coating: the corrosion-resistant surface is the stainless face of the panel itself, so there is nothing to blister, peel or repaint. Second, the panel is drawn rather than fabricated, so the water never touches a heat-affected zone where pitting normally starts. Third, every joint is closed with EPDM strip and stainless fasteners outside the water path, which means a single panel can be replaced years later without cutting the tank open. The module is reinforced on all four corners, and the wall is carried on a 16 mm section rated for a full 4.5 m of head.

At this volume the tank is laid out wide rather than deep, which keeps 5 mm panels to the lowest courses only: 20 × 10 × 5 m is the common arrangement, with 25 × 10 × 4 m and 20 × 12.5 × 4 m as alternatives. Internal tie rods brace the walls and are set out to leave an inspection route along the tank.
| Tank height | Panel thickness | Typical use |
|---|---|---|
| 1.0 – 1.5 m | 2 mm | Shallow buried reserve |
| 2.0 m | 3 mm | Standard buried tank |
| 3.0 m | 4 mm | Deep reserve, high head |
| 4.0 – 4.5 m | 5 mm | Maximum depth, pump station |
Every food grade BDF tank is filled and held at full head for 48 hours before it leaves the factory, and no joint is allowed to weep. The composite plate carries drinking-water contact report SP2630499 from the Dezhou Institute of Product Quality Standards and Metrology, and the plant holds ISO 9001 with CE marking on the product. Copies of the report and the certificate ship with the order, and you can see the full set on our certifications page. The same specification is published on our Made-in-China storefront, where LVJIA is an audited supplier.
Pricing for the food grade BDF tank starts at US$200 per cubic metre, falling to US$180 from 10 m³ and US$150 from 50 m³, FOB Tianjin or Qingdao. The minimum order is one set. Samples ship in 3 to 5 days and batch orders in 15 to 25 days from Dezhou, Shandong, on wooden pallets. Chlorine dosing and recirculation connections are cut and flanged alongside the inlet, outlet, drain and overflow. A 1000 m³ tank ships as flat pressed panels on wooden pallets, which is what makes this size practical to freight.
Send the pit dimensions and the volume you need and LVJIA returns an arrangement drawing and a panel schedule before you commit to anything. If you would rather talk it through first, our engineers answer specification questions directly through technical help, and the rest of the range sits on the BDF underground water tank page.
Where another material suits the site better, the GRP potable water tank is the same tank in moulded GRP, for sites where no metal may touch the water, while the stainless steel drinking water tank builds it in stainless steel. Elsewhere in the BDF underground range there is the two compartment BDF tank for general-purpose duty and the BDF composite water tank for general-purpose duty.
At a glance
Every tank is built to the pit you have. The module is a 1000 × 1000 mm pressed panel, so capacity steps in whole cubic metres and the arrangement can be long and shallow or short and deep without changing the parts list.
