Modular Water Tank Installer Serving Metro Manila Projects

JOHOB Hardware Trading supplies modular water storage tanks to commercial, industrial, and institutional buyers across Metro Manila, and coordinates on-site installation through our sister brand TankSmith, which specializes in turnkey modular tank installs. This means a single point of contact for sourcing, delivery, and installation coordination instead of managing a supplier and an installation crew separately. Tanks are sourced through ISO 9001 certified partner factories, so the quality management system behind every unit is independently certified, not a claim we make about our own facility. For Metro Manila projects, this covers new installations for buildings adding water storage capacity, replacement of aging tanks, and expansion projects where an existing system needs additional modular capacity. Buyers typically include property managers, facilities engineers, and contractors sourcing on behalf of a Metro Manila site. Because pricing is quote-based and depends on capacity, material, and site conditions, we do not publish fixed prices; every project starts with an RFQ so the quote reflects the actual site and specification rather than a generic estimate. This page describes what is available and how the process works, so a buyer can scope a Metro Manila installation before requesting a quote.

Coverage extends across Metro Manila as part of JOHOB's nationwide reach, which also spans Luzon, Visayas, Mindanao, and PEZA, SBMA, and Clark economic zones. For Metro Manila buyers, this means the same lead times and terms apply as the rest of the nationwide network, with no separate surcharge structure described here. Standard lead time is 21 to 35 days ex-stock for tanks already available through partner factory inventory, and 45 to 90 days for made-to-order units built to a specific capacity or material spec. Every RFQ receives a response within 1 business day, which lets a Metro Manila buyer confirm feasibility and rough timeline before committing to a full technical submittal. Lead time is the single biggest planning variable for a Metro Manila project, since site readiness (civil works, access for delivery, and any existing plumbing tie-in) needs to align with the ex-stock or made-to-order window. Buyers planning a tight construction schedule should request a quote early so the 21 to 35 day or 45 to 90 day window can be built into the project timeline rather than discovered after other trades are already scheduled. Nationwide coverage also means a Metro Manila order draws on the same supply chain as any other region, so lead times are not shortened or extended based on proximity to Manila.

Modular water tanks supplied through JOHOB carry WRAS-certified panels, meaning the panel material meets the UK Water Regulations Advisory Scheme standard for materials in contact with drinking water, a specification Metro Manila buyers with potable water storage requirements can reference directly in a technical submittal. Tanks also ship from ISO 9001 certified partner factories, which certifies the factory's quality management system rather than the tank product itself, and are TUV SUD tested, an independent third-party testing standard. These three certifications, WRAS-certified panels, ISO 9001 certified manufacturing, and TUV SUD testing, are the specific standards that apply to modular water storage tanks; other certifications JOHOB references elsewhere, such as CE marking or ASME pressure vessel standards, apply to different product categories (electrical panels and material handling equipment, and pressure vessels respectively) and are not claimed here since modular water storage tanks are atmospheric, not pressure-rated equipment. A Metro Manila buyer preparing a technical submittal or bid document can cite WRAS, ISO 9001, and TUV SUD as the verifiable standards behind the tank, without needing to request additional documentation before the RFQ stage. These certifications apply to the tank and its manufacturing process; installation coordination itself is a service provided through TankSmith rather than a certified process.

Installation for Metro Manila projects is coordinated through TankSmith, JOHOB's sister brand for turnkey modular water tank installs. In general, a modular tank installation follows a sequence: site assessment to confirm foundation, access, and plumbing tie-in points, delivery of the modular panels to site, on-site assembly of the panel sections into the finished tank structure, and final commissioning and leak testing before handover. Because modular tanks are built from bolted panel sections rather than a single welded shell, on-site assembly is typically faster than a field-welded stainless steel tank of comparable capacity, which matters for a Metro Manila site with a compressed construction schedule. Buyers should expect the installation coordination to run in parallel with the delivery lead time already described (21 to 35 days ex-stock or 45 to 90 days made-to-order), not as a separate timeline stacked on top of it. Every Metro Manila installation starts with an RFQ so that site-specific factors, access width for delivery trucks, crane requirements if the site has limited ground access, and the condition of any existing plumbing to tie into, can be scoped before a quote is issued. This page describes the general process; project-specific details are confirmed during the RFQ and site assessment stage rather than assumed in advance.

JOHOB supplies modular water storage tanks in FRP/GRP (fiberglass reinforced plastic, also called glass reinforced polyester), stainless steel, and HDG (hot-dip galvanized) construction, all available for Metro Manila delivery under the same lead time structure described above. FRP/GRP panels are corrosion-resistant by material and commonly specified for potable water storage where WRAS-certified panel material is a requirement. Stainless steel modular tanks are typically specified where a buyer wants a non-porous, easy-to-clean interior surface, often for food-grade or institutional applications. HDG modular tanks use a galvanized steel panel system and are typically the lower-cost option among the three for buyers prioritizing budget over material-specific advantages. The right material depends on the water use (potable, process, or fire reserve), the site's exposure conditions, and the buyer's maintenance preference, so material selection is confirmed during the RFQ stage rather than assumed from the query alone. A Metro Manila buyer unsure which material fits their project can request a quote specifying the intended use, and the RFQ response within 1 business day will include material guidance specific to that use case rather than a generic recommendation.

Modular water tank pricing is quote-based; JOHOB does not publish fixed prices since capacity, material, site conditions, and installation coordination scope all affect the final quote. Standard VAT-registered Metro Manila buyers are subject to the standard 12% VAT rate. Buyers operating as PEZA or SBMA locators, or as exporters, may qualify for zero-VAT terms on the transaction, which should be confirmed during the RFQ process with the relevant documentation. To start an order, a Metro Manila buyer submits an RFQ describing the intended capacity, material preference if known, and site location; JOHOB responds within 1 business day with a quote reflecting the ex-stock (21 to 35 day) or made-to-order (45 to 90 day) lead time that applies. Installation coordination through TankSmith is scoped as part of the same RFQ process rather than as a separate quote request, so a buyer receives a single quote covering both supply and installation coordination. This keeps the ordering process to a single point of contact from initial RFQ through installation handover, which is the main practical benefit of sourcing supply and installation coordination through the same RFQ rather than two separate vendors.
