6m x 6m Water Tank Details: Capacity, Specs, and DPWH-Ready Options

A DPWH tank detail that specifies "6m x 6m" is describing a footprint, not a finished capacity. Six meters by six meters gives 36 square meters of floor area. That number alone tells a buyer nothing about how much water the tank holds, because volume also depends on wall height, which most tank details list separately or leave to the mechanical/plumbing plan. This is why the exact phrase "6m x 6m water tank details dpwh" turns up in searches: whoever is pricing or building the tank needs the missing dimension converted into liters before they can spec a pump, a float valve, or a fire reserve requirement under the National Plumbing Code of the Philippines (NSPC) or the National Building Code (NBC). A poured concrete cistern built to a 6m x 6m footprint and a modular panel tank built to the same footprint should hold the same volume at the same height, since the geometry does not change with material. What changes is construction time, weight on the supporting slab, and how easily the structure can be resized later if the project scope shifts. JOHOB Hardware Trading works with contractors and facility owners on exactly this translation step: taking a footprint called out in a bid document or as-built plan and matching it to a tank package with a confirmed liter capacity, material, and certification set before procurement moves forward.

Once a height is added to the 6m x 6m footprint, capacity is straightforward: length times width times height, converted at 1,000 liters per cubic meter. At 1 meter of water depth, a 6m x 6m tank holds 36 cubic meters, or 36,000 liters. At 1.5 meters, it holds 54,000 liters. At 2 meters, 72,000 liters. At 2.5 meters, 90,000 liters. At 3 meters, 108,000 liters. These figures assume the full 36 square meter footprint is usable water volume, with no deduction for wall thickness, baffles, or freeboard, so treat them as a starting reference rather than a final design number. All of these outputs sit comfortably inside the capacity range JOHOB's modular tank line is built to cover, from 10,000 liters up to 500,000 liters and above, which means a 6m x 6m specification does not require a custom one-off fabrication run. If a DPWH detail or as-built drawing lists a height that is not on this list, the same formula applies: multiply the two footprint dimensions by the water depth in meters, then multiply by 1,000 to get liters. Buyers pricing a project should confirm which depth the specification actually calls for before requesting a quote, since the difference between a 1-meter and a 3-meter tank at the same footprint is a threefold change in stored volume, structural load, and price.

A 6m x 6m footprint does not have to be built as a single poured concrete structure. JOHOB Hardware Trading supplies modular FRP (fiberglass reinforced plastic), GRP, hot-dip galvanized (HDG), and stainless steel panel tanks, assembled from bolted sectional panels sized to match footprints like 6m x 6m without a custom mold or form work. Because the panels are modular, the same 6m x 6m tank can be built taller or reconfigured to a different footprint later if a project's water demand changes, which a fixed concrete pour cannot do without demolition. These panel systems are supplied under JOHOB's sister brand, TankSmith, for turnkey installs that include the tank shell, structural supports, and fittings as one package. The panels themselves are WRAS-certified, and the manufacturing partner behind them holds ISO 9001 quality management certification and TUV SUD testing; no manufacturer, factory, or country of origin is disclosed here, only that the equipment is sourced through a vetted overseas manufacturer with third-party certification on file. For projects that also need pressure vessels as part of the water system, ASME certification applies where relevant. This modular approach is the practical alternative for anyone who searched "6m x 6m water tank details dpwh" looking to price a tank against a fixed footprint spec without committing to poured concrete: the same 36 square meter base, in a material and assembly method that ships and installs faster than formwork and curing time allow.

Before ordering a tank against any footprint specification, including 6m x 6m, confirm the certifications behind the equipment rather than taking a capacity number at face value. JOHOB's supplied tank panels carry WRAS certification, meaning they are approved for contact with potable water. The manufacturing partner operates under an ISO 9001 quality management system and has TUV SUD test reports on file, which a buyer can request as part of due diligence on a government or institutional project. Electrical components tied to the water system, such as VFD panels for booster or transfer pumps, carry CE marking. Where the project includes pressure vessels, ASME certification applies. None of JOHOB's supplied equipment is PCAB-licensed or PCAB-certified, since PCAB accreditation applies to contractors, not equipment suppliers, and this distinction matters for anyone matching a tank quotation against a DPWH bid requirement that specifies contractor accreditation separately from equipment specification. Ask any supplier quoting a 6m x 6m or similarly sized tank to provide documentation for each certification relevant to the project's use case (potable water storage, fire reserve, process water) rather than a generic spec sheet, since the certification set that applies to a fire suppression reserve is not identical to the set that applies to a potable water cistern of the same footprint.

JOHOB Hardware Trading delivers modular tank packages nationwide across the Philippines, covering NCR, Luzon, Visayas, and Mindanao, including PEZA, SBMA, and Clark locations. Standard lead time for ex-stock tank components is 21 to 35 days; made-to-order configurations, which most non-standard footprints require, run 45 to 90 days from order confirmation. Pricing is quote-based and not published publicly, since a 6m x 6m tank package price depends on material choice (FRP, GRP, HDG, or stainless steel), height, accessories, and site access. Standard 12% VAT applies to VAT-registered buyers; PEZA and SBMA locators and exporters qualify for zero-VAT treatment on the transaction. RFQs submitted through JOHOB receive a response within 1 business day. To request a quote for a 6m x 6m footprint tank, provide the required height or capacity in liters, the intended use (potable water, fire reserve, or process water), the installation site's region, and whether the buyer holds PEZA/SBMA/zero-VAT status, so the quotation reflects the correct tax treatment and lead time from the first response.
