A potable water tank stores drinking-grade water using WRAS-certified panels or NSF-compliant liners, in capacities from 1,000 liters to 500,000 liters. TankSmith supplies and installs modular FRP, GRP, HDG steel, and stainless steel bolted panel systems nationwide across the Philippines, each backed by a 3-year panel warranty and a 20 to 25 year design life, in 5 to 14 days per install.
What Is a Potable Water Tank
A potable water tank is a storage system built specifically to hold water safe for drinking, cooking, and other human-contact use, as distinct from tanks built only for fire reserve or process water. The material in contact with the water, and any liner used, has to meet a recognized potable-water standard rather than just being watertight. TankSmith builds potable water tank systems using WRAS-certified panels, rated for potable water up to 65C, and NSF-compliant liners where a liner is specified. Every system uses materials from an ISO 9001 certified manufacturer QMS and panels that have been TUV SUD tested. These are the same certification marks that food manufacturing plants, hospitals, and hotel groups check for before signing off on a water storage supplier in the Philippines. TankSmith is a Philippines-based turnkey installer: the same team that supplies the tank also handles the pressure side, sizing and installing a matching booster pump system, and commissions both under one contract. That single-team accountability matters for potable water systems specifically, because a tank that meets a potable standard on paper still needs a pump and control setup that does not introduce contamination risk at the connection points, and coordinating that between two separate contractors is where most installation delays and disputes happen.
Materials for Potable Water Storage: FRP, GRP, HDG Steel, and Stainless Steel
TankSmith supplies potable water tank panels in four materials: FRP (fiberglass reinforced plastic) bolted panels, GRP / SMC (sheet moulded compound), HDG steel (hot-dip galvanized), and stainless steel in 304 or 316 grade. All four are available as modular bolted panel systems, assembled on site rather than shipped as a single vessel, which is what makes capacities from 1,000 liters to 500,000 liters practical to install on a rooftop or a tight ground-level pad. FRP and GRP panels are the most common choice for potable water because the WRAS certification and NSF-compliant liner options apply directly to these materials. HDG steel is a common choice where budget or structural load is the deciding factor, and stainless steel 304 or 316 is specified where the project calls for a higher grade finish, such as food manufacturing plants with strict potable water requirements. Every FRP panel TankSmith installs carries a 3-year warranty on the panel, with a 20 to 25 year design life for the system as a whole. The choice between materials is a project-by-project decision based on water quality requirements, budget, structural constraints, and whether the site already has an existing tank pad to match.
Capacity: Sizing a Potable Water Tank from 1,000 Liters to 500,000 Liters
TankSmith's potable water tank systems range from 1,000 liters, sized for a small clinic or a single-building booster feed, up to 500,000 liters for an industrial estate or a multi-tower condominium development. Because the panels are modular and bolted rather than a fixed single-piece vessel, the same product line covers that entire range without switching manufacturing processes between a small and a large order. Sizing depends on the vertical. Commercial laundry operations are sized against kg/day linen throughput rather than a flat capacity guess. Hospitals and clinics size for redundancy and a code-compliant fire reserve on top of daily potable demand. Hotels and resorts sizing a rooftop retrofit need to account for booster pump integration alongside the tank itself, since a rooftop location changes the pressure calculation. Condominiums and high-rise buildings typically face the added constraint of tight rooftop access, which affects panel size and crane or hoist requirements as much as it affects total capacity. Typical install timelines run 5 to 14 days for installs between 20 KL and 500 KL, depending on the exact capacity and how ready the site's civil works (the concrete pad, tank room, or rooftop structure) are before the crew arrives. Sites with civil work already complete move toward the shorter end of that window.
Turnkey Tank and Booster Pump System
A potable water tank on its own only solves storage. Most Philippine sites, especially multi-story buildings and industrial estates, also need a booster pump system to get that stored water to the point of use at usable pressure. TankSmith supplies and installs both under one contract rather than splitting the tank and the pump between separate vendors. The pump side uses vertical multistage centrifugal booster pumps (CDL/CDLF series), available from 0.37 kW up to 200 kW, in SS304 construction. Pairing that pump range with a 1,000 liter to 500,000 liter tank range covers everything from a single small commercial building to a full industrial estate on one supplier relationship. Pump control runs through VFD duplex control panels built around Inovance VFDs, rated IP54, with pressure feedback and auto-alternation between duplex pumps. That control setup is what keeps pressure stable as demand changes through the day and lets a duplex pump pair share wear evenly instead of running one pump continuously. Because the same team handles the mechanical tank install, the pump and control electrical work, and commissioning, there is one point of accountability if something does not perform as specified after handover, instead of a tank supplier and a pump supplier pointing at each other.
Where TankSmith's Potable Water Tanks Are Used in the Philippines
TankSmith's potable water tank systems are installed across commercial laundry facilities, hotels and resorts, hospitals and clinics, food manufacturing plants, warehouses and manufacturing sites, and condominium or high-rise buildings. Each vertical brings a different sizing and certification priority: food manufacturing plants need WRAS-compliant potable water documentation, hospitals need redundancy and fire reserve compliance, and hotel rooftop retrofits need the tank and booster pump sized together rather than sequentially. Coverage is nationwide: Metro Manila, wider Luzon, Visayas, and Mindanao, including sites inside PEZA and freeport zones such as SBMA, Clark, Cavite, and Batangas. Industrial estate sites in these zones often carry stricter civil and safety requirements before installation can start, which is one more reason the 5 to 14 day install window depends on how ready the site is, not just the tank's capacity. For any of these verticals, the certification set is the same across the country: WRAS-certified panels for potable water up to 65C, NSF-compliant liners where specified, ISO 9001 certified manufacturer QMS, and TUV SUD tested panels. A procurement team evaluating a potable water tank supplier for a PEZA-registered plant in Cavite can expect the same certification documentation as a hospital in Metro Manila or a resort in Visayas.
Certifications, Warranty, and What to Check Before You Buy
Before signing off on a potable water tank supplier, a Philippine buyer should ask for four things: WRAS certification on the panels themselves (not just the liner), an NSF-compliant liner where a liner is used, confirmation the manufacturer holds ISO 9001 certification, and TUV SUD test documentation on the panels. These are the same four checks TankSmith's own systems are built to. Warranty terms matter as much as the certification list. TankSmith's FRP panels carry a 3-year warranty, and the system as a whole is built for a 20 to 25 year design life. Ask any supplier for their warranty term and design life in writing, not as a verbal claim, and confirm what specifically is covered under the panel warranty versus the pump and control system. Because TankSmith installs the tank and the booster pump system together, the commissioning step covers both the mechanical tank assembly and the electrical VFD control panel setup before handover. A buyer comparing quotes should confirm whether a competing quote includes commissioning of the full system, tank and pump together, or only the tank, since a tank-only quote that looks lower can end up costing more once a separate pump contractor and a second commissioning visit are added.
Frequently Asked Questions
What is the smallest and largest potable water tank TankSmith can install?
TankSmith's potable water tank systems range from 1,000 liters up to 500,000 liters, using modular FRP, GRP, HDG steel, or stainless steel bolted panels. The modular bolted design covers that full range without changing manufacturing process, so a small clinic feed and a 500 KL industrial estate tank use the same panel technology, just more or fewer panels. Typical install timelines run 5 to 14 days for the 20 KL to 500 KL range, depending on capacity and how ready the site's civil works are before the installation crew arrives.
Is TankSmith's potable water tank certified for drinking water?
Yes. TankSmith's potable water tank panels are WRAS-certified for potable water up to 65C, with NSF-compliant liners available where a liner is specified. The manufacturing partner holds ISO 9001 certified QMS, and panels are TUV SUD tested. These are the certification documents a food manufacturing plant, hospital, or hotel procurement team should ask for before approving a water storage supplier in the Philippines.
What is the warranty on a TankSmith potable water tank?
TankSmith's FRP panels carry a 3-year warranty, and the tank system as a whole is built for a 20 to 25 year design life. Ask for both figures in writing when comparing suppliers, and confirm whether the quoted warranty covers the panels only or the full installed system. TankSmith supplies and installs the tank and a matching booster pump system under one contract, so warranty and commissioning responsibility for both sides sits with a single team rather than split across separate tank and pump vendors.
Does TankSmith also supply the booster pump, or just the tank?
Both. TankSmith supplies vertical multistage centrifugal booster pumps (CDL/CDLF series, 0.37 kW to 200 kW, SS304) alongside the tank, controlled through VFD duplex control panels built on Inovance VFDs, IP54 rated, with pressure feedback and auto-alternation. The tank and pump are supplied, installed, and commissioned under one contract, mechanical and electrical, so there is a single point of accountability if the system does not perform as specified after handover.
Which materials are available for a potable water tank in the Philippines?
TankSmith offers four panel materials for potable water storage: FRP (fiberglass reinforced plastic), GRP / SMC (sheet moulded compound), HDG steel (hot-dip galvanized), and stainless steel in 304 or 316 grade. FRP and GRP are the most common choice for potable water projects because WRAS certification and NSF-compliant liner options apply directly to these materials. The right material depends on water quality requirements, budget, structural load, and whether the site has an existing tank pad. All four are available across the full 1,000 liter to 500,000 liter capacity range.
Where in the Philippines does TankSmith install potable water tanks?
Nationwide: Metro Manila, wider Luzon, Visayas, and Mindanao, including PEZA and freeport zone sites such as SBMA, Clark, Cavite, and Batangas. Common project types include commercial laundries, hotels and resorts, hospitals and clinics, food manufacturing plants, warehouses, and condominium or high-rise buildings. Install timelines run 5 to 14 days for 20 KL to 500 KL systems, and industrial estate or freeport zone sites may have additional civil and safety requirements to clear before installation starts.
