What a 50 KL Water Storage Tank Means on a Philippine Site
A 50 KL water storage tank holds 50,000 liters, which is 50 cubic metres of usable volume. Buyers in the Philippines see the same tank written three ways in tender documents and supplier quotations: 50 KL, 50,000 L and 50 m3. They all describe the same storage duty, and TankSmith quotes against all three without changing the specification. Fifty cubic metres sits in the middle of what we build: TankSmith supplies modular bolted panel tank systems from 1,000 liters to 500,000 liters per tank, so a 50 KL requirement is a standard configuration rather than a stretch at either end of the range. Because the tank is assembled from bolted panels rather than delivered as one moulded vessel, the footprint is set by your available slab, not by what fits through a gate. Fifty cubic metres of internal volume is simple arithmetic: a 5 m by 4 m by 2.5 m interior and a 5 m by 5 m by 2 m interior both reach 50 m3, and there are several other combinations. The right one depends on your headroom, your slab dimensions and the draw off level you need. We confirm the final panel layout at site survey before anything is fabricated, so the configuration on the quotation is the configuration that gets installed. For build sequence detail, see the 50 KL installation timeline breakdown.
Panel Materials for a 50 KL Tank: FRP, GRP, HDG Steel and Stainless Steel
TankSmith supplies 50 KL modular bolted panel tanks in four panel materials, and the choice is a specification decision rather than a budget decision. FRP and GRP bolted panel tanks are the common starting point for potable storage, with FRP covered by a 3-year panel warranty; GRP and SMC (sheet moulded compound) panels sit in the same family and are specified where the moulding process and panel finish are called out in the tender. HDG steel panel tanks (hot-dip galvanized) are chosen where structural loading, impact exposure or plant room conditions favour a steel shell. Stainless steel panel tanks in 304 and 316 are specified where the stored water, the ambient chemistry or the client standard requires a stainless wetted surface, with 316 the usual answer near coastal air or aggressive process conditions. Across all four materials the design life we work to is 20 to 25 years, so material selection at 50 KL is about matching the environment and the compliance requirement, not about buying a shorter or longer service life. Panels are bolted, which means a 50 KL tank can be expanded later using replacement and expansion panels rather than being replaced outright. If your specification names one material and your site conditions point at another, tell us at enquiry stage and we will quote both so the comparison is on paper before you commit. For peso context by material, see the water tank price guide for the Philippines.
Potable Water Compliance: WRAS-Certified Panels and NSF-Compliant Liners
If your 50 KL tank stores drinking water, the compliance question comes before the price question. TankSmith supplies WRAS-certified panels rated for potable water up to 65C, and NSF-compliant liners where the specification calls for a lined system; the full documentation trail is set out on the WRAS-certified water tanks in the Philippines page. Panels are produced under an ISO 9001 manufacturer quality management system, and TUV SUD tested panels are available where third party test evidence has to be attached to a submittal. That combination is what procurement, consultants and building officials usually want to see documented, and it is the part of a 50 KL enquiry that most often stalls when a supplier cannot produce paperwork. The 65C rating matters more than it looks on a Philippine site: rooftop and exposed plant room installations run hot, and commercial laundry and food manufacturing operations put warm water back into storage, so the certified temperature ceiling is a live constraint rather than a formality. TankSmith names the certification against the panel being quoted, so you are not asked to accept a general claim about the brand and then discover the supplied panel sits outside it. We also flag where a potable specification changes the material recommendation, for example where a lined system or a stainless wetted surface is the cleaner route to sign off on a food manufacturing or hospital project.
The Pressure Side: Booster Pumps and VFD Duplex Control for a 50 KL System
Storage on its own does not deliver pressure. A 50 KL tank fixes your reserve volume, and the booster pump set fixes whether the top floor gets usable flow at peak demand. TankSmith supplies both under one contract, which is the difference between buying a tank and buying a water system. Our pump side is vertical multistage centrifugal pressure booster pump systems from the CDL and CDLF series, from 0.37 kW to 200 kW, in SS304. That range covers a 50 KL installation whether the tank feeds a low rise clinic or a high rise riser. Control is by VFD duplex control panel using Inovance variable frequency drives, rated IP54, with pressure feedback and automatic alternation between pumps. Pressure feedback means the drives modulate to hold setpoint instead of cycling hard against a pressure switch, and auto-alternation means duty is shared between the two pumps rather than accumulating on one. On a split scope, the tank contractor and the pump contractor each certify their own half and any commissioning problem lands in the gap between them. TankSmith takes single-team accountability for supply, installation and commissioning of both the storage side and the pressure side, so there is one contract, one commissioning event and one party answerable for the delivered pressure at the outlet.
Installation Timeline and Site Readiness for a 50 KL Tank
Typical TankSmith installs in the 20 KL to 500 KL range run 5 to 14 days, and where a 50 KL job lands inside that window depends on capacity and civil readiness rather than on the tank itself; the stage-by-stage programme is on the installation timeline page. The variable that moves the date is almost always the slab. A modular bolted panel tank needs a level, cured, correctly loaded base sized to the agreed panel layout, and it needs access for panel delivery to the installation level. Where the slab is ready and access is clear, a 50 KL install sits at the shorter end. Where civil works are still in progress, or where panels have to be carried up through a stair core on a rooftop retrofit, it moves toward the longer end. Bolted panels are what makes tight-access work possible at all: panels are brought in individually and assembled in place, so a 50 KL tank can be installed on a rooftop, in a basement plant room or inside an existing enclosure that no pre-formed vessel of that volume could ever enter. We confirm access route, slab condition and panel layout at survey, then commit to a date range with the constraints written down, rather than quoting a number and renegotiating it on arrival. Commissioning of the pump set and control panel is included in the same programme.
Where We Supply and Install 50 KL Tanks, and Who Buys Them
TankSmith supplies and installs nationwide across the Philippines: NCR, the rest of Luzon, Visayas and Mindanao, including PEZA and freeport locations such as SBMA and Clark. A 50 KL requirement outside Metro Manila is a normal job for us, not an exception that changes the specification. The sectors that most often specify around this volume are the ones we build for regularly: commercial laundry operations, where storage is sized against kg per day linen throughput; hotels and resorts, where a rooftop retrofit has to be paired with booster pump integration, as covered on the 50 m3 hotel water tank in Metro Manila page; hospitals and clinics, where redundancy and a code-compliant fire reserve drive the sizing, detailed on the 50 m3 hospital water tank in Metro Manila page; food manufacturing, where WRAS-compliant potable storage is non-negotiable; warehouses and manufacturing plants, where the split between fire reserve and process water sets the volume, with the fire duty covered on the 50 m3 fire reserve tank in Metro Manila page; and condominiums and high-rise buildings, where rooftop placement and tight-access retrofit rule out anything that is not bolted panel construction, as on the 50 m3 condominium water tank in Makati page. Larger campus and estate requirements step up to 500 KL water reservoir tanks. TankSmith was founded in 2024 and works as a turnkey installer rather than a parts vendor, so a 50 KL enquiry is answered with a configuration, a material recommendation, a pump selection and a commissioning scope, not a panel price list.
Frequently Asked Questions
There is no single price for a 50 KL tank because the cost moves with panel material, tank configuration, site access and whether the booster pump system and control panel are in scope. An FRP system and a stainless steel 316 system at the same 50,000 liter volume are different builds. TankSmith quotes after a site survey confirms slab condition, access route and panel layout, so the figure covers supply, installation and commissioning rather than panels alone. Send the intended use, location and available slab dimensions and we will scope it.
Typical installs in the 20 KL to 500 KL range take 5 to 14 days, and a 50 KL tank sits inside that window. Where it lands depends on capacity and civil readiness. A level, cured, correctly loaded slab and a clear delivery route to the installation level push the job toward the shorter end. Civil works still in progress, or panels that have to be carried up a stair core on a rooftop retrofit, push it toward the longer end. Commissioning of the pump set and control panel is included in the same programme.
Yes, when the correct panels are specified. TankSmith supplies WRAS-certified panels rated for potable water up to 65C, and NSF-compliant liners where a lined system is called for. Panels are produced under an ISO 9001 manufacturer quality management system, and TUV SUD tested panels are available where a submittal needs third party test evidence attached. The 65C ceiling matters on Philippine rooftops and in commercial laundry or food manufacturing operations that return warm water to storage. Tell us the stored water duty at enquiry stage and we will specify to the compliance requirement.
Yes. A 50 KL modular tank is assembled from bolted panels carried in individually, so it can be built on a rooftop, inside a basement plant room or within an existing enclosure that no pre-formed vessel of 50,000 liters could enter. The footprint is set by your slab rather than by a fixed vessel shape, and 50 cubic metres can be reached through several interior dimension combinations. Rooftop retrofit and tight-access condominium and high-rise work is a regular part of what we install. Access route and slab loading are confirmed at survey before fabrication.
Yes, and we recommend buying both together. TankSmith supplies vertical multistage centrifugal booster pumps in the CDL and CDLF series from 0.37 kW to 200 kW in SS304, with VFD duplex control panels using Inovance drives, rated IP54, with pressure feedback and automatic alternation between pumps. Storage and pressure are supplied, installed and commissioned under one contract with single-team accountability, so there is one commissioning event and one party answerable for delivered pressure at the outlet instead of a tank contractor and a pump contractor certifying separate halves.
Yes. Coverage is nationwide across the Philippines: NCR, the rest of Luzon, Visayas and Mindanao, including PEZA and freeport locations such as SBMA and Clark, plus the Cavite and Batangas industrial estates. A 50 KL install in a provincial or freeport location is handled as a standard job with the same scope: supply, installation and commissioning of the tank and the booster pump system under one contract. Send the site location with the enquiry so the survey, delivery route and installation programme are scoped correctly from the start.
