SS304 Sectional Water Tanks from 1,000 Liters to 500,000 Liters
TankSmith supplies and installs SS304 sectional water tanks across the Philippines, in capacities from 1,000 liters to 500,000 liters per tank system. A sectional tank is assembled on site from bolted stainless steel panels rather than delivered as one welded vessel. That is the practical reason specifiers choose it: flat panels move through doorways, lift shafts, and stair cores, so a rooftop plant room or a basement pump room that no crane can reach still gets its storage. It also means one capacity can take several shapes. The same 100 KL requirement can be built tall and narrow where the roof deck is small, or long and shallow where headroom is the limit. Grade 304 is the default stainless specification for potable and general process water, and it is the same grade used in the wetted parts of the booster pumps we install, which keeps the storage side and the pressure side on one consistent material spec. TankSmith also supplies the same modular bolted format in FRP, GRP or SMC, HDG steel, and stainless steel 316, per the stainless steel panel tank specifications, and the full set of sectional water tank materials compared for Philippine projects, so the material decision can stay open until the water analysis, the site constraints, and the budget are all on the table. If SS304 turns out to be the wrong answer for your water, we will say so at quotation stage rather than after installation. Scope is quoted as supply, installation, and commissioning under one contract, with the option to include the matching pressure booster pump system in the same scope.
When to Specify SS304, and When SS316 or FRP Is the Better Answer
SS304 suits potable water and general process water in buildings where the water chemistry is unremarkable. Where chlorides are the concern, meaning brackish supply, heavily chlorinated water, or a coastal site with salt-laden air, SS316 is the safer specification, because the added molybdenum improves resistance to chloride pitting. That difference is worth resolving before the order rather than after, so send a water analysis with your enquiry and we will specify against it. Both grades ship as stainless steel modular water tank systems in 304 and 316. FRP and GRP or SMC bolted panels remain the volume choice in the Philippines on cost and on chemical resistance, and they carry a 3-year FRP panel warranty. HDG steel suits fire reserve and process duty where potable contact is not the driver. Stainless steel earns its price where hygiene and appearance are audited, where the water runs hot, or where the tank sits in public view. Design life across the modular range is 20 to 25 years. Note the shape of the decision as well as the material: on a sectional tank, panels can be replaced and the tank can be expanded later, which is not true of a poured concrete tank once it is cast; the FRP vs stainless vs concrete comparison lays those trade-offs out side by side. TankSmith installs all four materials, so there is no incentive to push you toward stainless if FRP does the job. Ask for a two-material quotation and compare the figures side by side, with the potable certification requirement stated explicitly on both. That comparison is also the quickest way to test any supplier: one that quotes only stainless is selling a product, while a supplier that prices two materials against the same duty and the same certification requirement is actually specifying a system for your building.
WRAS-Certified Panels, NSF-Compliant Liners, and the Documentation You Can Submit
TankSmith does not manufacture panels, and it is worth being direct about that, because it changes what you should ask for. The SS304 and SS316 bolted panels we supply are produced in ISO 9001 partner factories under a certified quality management system, with WRAS-certified water tank options rated for potable water up to 65 degrees Celsius, NSF-compliant liners where a liner forms part of the specification, and TUV SUD testing behind the panel range. In procurement terms, that means the certification you rely on comes from a documented manufacturer quality system with test evidence attached, not from a line of marketing copy on a website. Ask for the documentation set at quotation stage and check three things: that the WRAS certification covers the panel actually being supplied, that the temperature rating matches your duty (65 degrees Celsius is the potable limit on the WRAS-certified range), and that the liner specification is stated wherever potable contact matters. Hospitals, food manufacturing plants, and hotels are usually the projects where a submittal package gets read line by line, and those are the projects where a generic ISO badge on a homepage is not enough. TankSmith supplies the manufacturer documentation for your submittals, permit filings, and internal audit files. If a certification you need is not on the list above, we will tell you it is not available rather than write it into a proposal.
Supply, Install, and Commission Under One Contract in 5 to 14 Days
Most sectional tank problems in the Philippines are handover problems. A trader delivers panels, a separate crew bolts them up, a third party wires the pumps, and when the pressure is wrong at the top floor nobody owns the fault. TankSmith is structured against that: supply, installation, and commissioning sit under one contract, and the storage side and the pressure side are the responsibility of the same team. Typical installs of 20 KL to 500 KL run 5 to 14 days, per the installation timeline by capacity, set by capacity and by civil readiness. Civil readiness is usually what decides the schedule, since the plinth or supporting slab has to be level, cured, and clear of other trades before panel assembly can start. Rooftop retrofits on hotels and condominiums add access sequencing to the plan, because panels, bolts, and tools have to be staged through the same lift or stair core the building is still using. Where a booster pump system is in scope, mechanical and electrical commissioning are scheduled in the same window, so the system is proved under real demand instead of being signed off panel by panel. TankSmith was founded in 2024, which is why we would rather be judged on documentation, specification discipline, and the commissioning record on your own project than on claims about volume. Ask what the commissioning sign-off includes before you award the contract.
Matching SS304 Booster Pump and VFD Duplex Control
Storage without pressure solves half the problem. TankSmith supplies and installs vertical multistage centrifugal booster pumps in the CDL and CDLF series, from 0.37 kW to 200 kW, in SS304 construction, which pairs with an SS304 tank on a single material specification; the full pressure booster pump system range is specified there. Control is by VFD duplex control panel using Inovance variable frequency drives, rated IP54, running closed loop on pressure feedback with automatic alternation between the duty and standby pump. Pressure feedback matters because it holds a set pressure as demand swings, instead of cycling the pump hard against a switch, which is what shortens pump life in hotels and hospitals where draw-off is uneven through the day. Auto-alternation matters because it evens out running hours across both pumps rather than wearing one out first, and because a genuine standby has to be a pump that actually runs, not one that has sat idle for two years. IP54 is the practical enclosure rating for a plant room in Philippine humidity. Sizing follows the demand profile, not the tank: a hotel with simultaneous morning showers and a warehouse with intermittent process draw need different pump curves at the same storage volume. Quote the pump and the tank together and commissioning becomes one exercise, with one team accountable for the pressure at the highest fixture rather than two suppliers pointing at each other.
Verticals Served, Nationwide Coverage, and How to Request a Quotation
TankSmith serves commercial laundries (sized against kilograms of linen per day rather than guessed volume), hotels and resorts (rooftop retrofit with booster pump integration), hospitals and clinics (redundancy and code-compliant fire reserve), food manufacturing (WRAS-compliant potable specification), warehouses and manufacturing plants (fire reserve and process water), and condominiums and high-rise buildings (rooftop and tight-access retrofit). Coverage is nationwide: NCR, the rest of Luzon, Visayas, and Mindanao, including the PEZA, SBMA, Clark, Cavite, and Batangas industrial estates. Freeport and economic zone work carries paperwork that provincial work does not, including gate passes, contractor documentation, and zone-specific work permits, and these usually have to be arranged before panels can be brought on site. Flag the estate at enquiry stage and that documentation runs in parallel with fabrication and delivery instead of eating into the install week. To request an SS304 sectional water tank quotation, send five things: required capacity in liters or KL, the available footprint and height clearance, the water analysis or at least the water source, whether potable certification is required, and whether the pressure booster pump system is in scope. With those five inputs, TankSmith returns a specified system rather than a price per liter, and where a cheaper material would do the same job we will quote that option alongside the stainless one.
Frequently Asked Questions
SS304 is the usual specification for potable and general process water, and it is what most Philippine commercial buildings need. SS316 adds molybdenum, which improves resistance to chloride pitting, so it is the safer choice where the supply is brackish, heavily chlorinated, or drawn on a coastal site. TankSmith supplies both grades in the same bolted modular format, so send your water analysis with the enquiry and we will specify against it. Where chloride levels are unknown, we quote both grades so you can compare cost against risk before committing.
From 1,000 liters to 500,000 liters per tank system. Because the tank is assembled from bolted panels on site, the same capacity can be configured as a tall narrow tank for a small roof deck or a long shallow tank where headroom is limited. Larger requirements are handled as multiple tank systems, which also gives you redundancy, so one tank can be drained for cleaning and inspection without shutting the building down. Send your daily demand, available footprint, and slab or floor constraints and we will size the configuration against them.
Typical installs of 20 KL to 500 KL run 5 to 14 days, depending on capacity and civil readiness. Civil readiness is usually the deciding factor, since the plinth or supporting slab has to be level, cured, and clear of other trades before panel assembly starts. TankSmith handles supply, installation, and commissioning under one contract, so there is no gap between a delivery crew and a separate installer. Where the pressure booster pump system is in the same scope, mechanical and electrical commissioning are scheduled in the same window.
No. TankSmith does not manufacture panels. The stainless steel 304 and 316 bolted panels we supply are produced in ISO 9001 partner factories, with WRAS-certified panel options for potable water up to 65 degrees Celsius, NSF-compliant liners where a liner is specified, and TUV SUD testing. TankSmith is the supplier and installer: we specify the system, supply the panels, install them on site, and commission the finished tank. We can provide the manufacturer documentation set for your submittals, permit filings, and audit requirements.
Design life across the modular range is 20 to 25 years. Be precise about the warranty position: the 3-year panel warranty applies to FRP panels, so do not assume it transfers automatically to a stainless steel order. For SS304 and SS316 supply, ask for the warranty terms in writing on your quotation and we will state exactly what is covered and for how long. We would rather set that out clearly at quotation stage than have it argued after installation, which is also why we publish the FRP-specific scope of that warranty here.
Yes. Coverage is nationwide: NCR, the rest of Luzon, Visayas, and Mindanao. That includes the PEZA, SBMA, Clark, Cavite, and Batangas industrial estates, where gate passes, contractor documentation, and zone-specific work permits usually need to be arranged before panels can be brought on site. Flag the estate or freeport at enquiry stage so that documentation runs in parallel with fabrication and delivery, rather than holding up the installation week once the panels have already arrived.
