A pump-to-overhead-tank water system installation in the Philippines pairs a modular storage tank (1,000 to 500,000 liters, in FRP, GRP, HDG steel, or stainless steel) with a vertical multistage centrifugal booster pump and VFD duplex control panel, specified together so capacity, pump head, and pressure feedback match as one system. TankSmith supplies, installs, and commissions both sides under one contract in 5 to 14 days, depending on capacity and civil readiness.
What a Pump-to-Overhead-Tank Water System Includes
A pump-to-overhead-tank water system has three parts that must be specified together, not separately: the storage tank, the booster pump, and the control panel. The tank holds reserve capacity, sized from 1,000 liters up to 500,000 liters depending on building occupancy and fire reserve requirements. The booster pump moves water from the tank (or from a ground-level cistern feeding the overhead tank) at the pressure and flow rate the building needs. The VFD duplex control panel automates pump switching, maintains steady pressure through pressure feedback, and alternates between duplex pumps so wear is shared evenly and one pump can fail without taking down supply. TankSmith specifies, supplies, installs, and commissions all three components under one contract, which removes the coordination gap that shows up when a tank supplier and a separate pump contractor each deliver their piece on a different schedule and nobody owns the interface between them. This single-team accountability covers mechanical installation, electrical work, and commissioning before handover. The result is a system where tank capacity, pump curve, and control logic are matched from the design stage rather than reconciled on site after the equipment has already arrived.
Overhead Tank Specification: Materials and Capacity
TankSmith supplies modular bolted panel tanks in four materials: FRP (fiberglass reinforced plastic), GRP/SMC (sheet moulded compound), hot-dip galvanized (HDG) steel, and stainless steel 304 or 316. Capacity ranges from 1,000 liters for small commercial sites up to 500,000 liters for larger industrial or institutional installs, assembled from modular panels rather than a single welded shell, which matters for rooftop or tight-access retrofit sites where a one-piece tank cannot be craned in. Panels are WRAS-certified for potable water service up to 65C, with NSF-compliant liners available where a project calls for them. The manufacturing partner holds ISO 9001 certification and panels are TUV SUD tested. TankSmith backs the panels with a 3-year warranty and a 20 to 25 year design life. Material choice depends on the application: FRP and GRP suit most potable and process water storage, HDG steel is a lower-cost option for less corrosive environments, and stainless steel 304 or 316 is specified where corrosion resistance or food-grade contact is required. The modular bolted construction also means a damaged panel can be replaced without draining or rebuilding the whole tank, which keeps downtime shorter during maintenance than it would be with a welded tank.
Booster Pump and VFD Control Panel Specification
The pump side of the system uses vertical multistage centrifugal booster pumps from the CDL and CDLF series, ranging from 0.37 kW up to 200 kW, built in SS304 stainless steel for the wetted components. Multistage design lets a compact pump reach the head needed to push water up to a rooftop overhead tank without oversizing the motor. Pump sizing depends on the vertical lift to the tank, the pipe run length and diameter, and the peak demand flow rate the building draws at once. Each pump system pairs with a VFD duplex control panel rated IP54 for enclosure protection. The VFD varies pump speed to match demand rather than running at full speed and cycling on and off, which reduces pressure spikes and wear on the pump and piping. Pressure feedback from a sensor on the discharge line lets the panel hold a set pressure band automatically. Duplex configuration means two pumps share the load, alternating automatically so no single pump runs continuously, and if one pump needs service the other covers supply without an interruption. This pump-and-panel specification is identical whether it feeds an overhead tank directly or backs up a hydropneumatic system, and TankSmith sizes it against the tank specification above as one engineering exercise rather than two.
Installation Process and Typical Timeline
TankSmith installs pump-to-overhead-tank systems in 5 to 14 days from mobilization to commissioning, with the exact duration set by tank capacity and how ready the civil works are on arrival. A smaller rooftop retrofit at the lower end of the capacity range moves faster than a 500 KL industrial install with its own civil, structural, and electrical scope. The installation covers tank panel assembly on site, pump and control panel mechanical mounting, electrical connection and wiring to the panel, pressure and flow testing, and final commissioning before handover. Because one team handles supply, civil coordination, mechanical installation, electrical work, and commissioning, there is a single point of accountability if a pump curve does not match the piping as installed or if a tank panel seal needs adjustment during pressure testing. Site readiness is the main variable a building owner controls: a cleared, structurally approved rooftop or ground slab with electrical supply already run to the location keeps the install at the shorter end of the 5 to 14 day range. Projects that need new civil works, such as a rooftop structural upgrade to carry tank weight, add time outside the installation window itself and are scoped separately before the installation timeline starts.
Industries and Locations We Install For
TankSmith installs pump-to-overhead-tank systems across commercial laundry (sized to kg/day linen throughput), hotels and resorts (rooftop retrofit with booster pump integration), hospitals and clinics (built with redundancy and code-compliant fire reserve), food manufacturing (WRAS-compliant potable water), warehouses and manufacturing sites (fire reserve and process water), and condominiums and high-rises (rooftop installs under tight-access constraints). Coverage is nationwide across the Philippines, spanning NCR, the rest of Luzon, Visayas, and Mindanao, including PEZA and freeport zones such as SBMA, Clark, Cavite, and Batangas. Each vertical has a different sizing driver: a hospital system is sized around redundancy and fire code compliance rather than peak demand alone, while a condominium rooftop retrofit is constrained more by access and structural load limits than by raw capacity. Because the tank and pump are specified together under one contract, TankSmith can adjust the balance between storage capacity and pump duty to fit whichever constraint dominates a given site, rather than defaulting to a standard package that may oversize the tank or undersize the pump for that specific vertical.
Frequently Asked Questions
Overhead tank size depends on building occupancy, peak demand, and any fire reserve requirement that applies to the site. TankSmith supplies modular bolted panel tanks from 1,000 liters up to 500,000 liters, so sizing is matched to the specific building rather than rounded up to a standard size. Hospitals and sites with fire code requirements typically need more reserve capacity than a standard commercial building of the same size. TankSmith's team reviews occupancy, peak draw, and any applicable fire reserve code before finalizing a capacity recommendation as part of the installation scope.
TankSmith specifies vertical multistage centrifugal booster pumps from the CDL and CDLF series, ranging from 0.37 kW to 200 kW, built in SS304 stainless steel. Multistage design reaches the head needed to lift water to a rooftop tank without oversizing the motor. Pump selection is based on vertical lift, pipe run length and diameter, and peak flow demand for the specific building, paired with a VFD duplex control panel rated IP54 that automates pressure control and alternates between two pumps so one failure does not interrupt supply.
Typical installation runs 5 to 14 days from mobilization to commissioning for systems in the 20 KL to 500 KL range, with the exact duration set by tank capacity and how ready the site's civil works are on arrival. A smaller rooftop retrofit on a site with electrical supply already run to the location moves toward the shorter end of that range. Larger industrial installs with their own civil or structural scope take longer, and that additional civil work is scoped separately before the installation timeline itself begins.
TankSmith handles both. The system is delivered as one turnkey contract covering tank supply, pump supply, mechanical installation, electrical connection and wiring to the VFD duplex control panel, pressure and flow testing, and final commissioning. One team is accountable for the full install rather than splitting the tank, pump, and electrical work across separate contractors who each deliver their piece on a different schedule.
TankSmith's modular bolted panels are WRAS-certified for potable water service up to 65C, with NSF-compliant liners available where a project requires them. The manufacturing partner holds ISO 9001 certification for its quality management system, and panels are TUV SUD tested. TankSmith backs the tank with a 3-year warranty and a 20 to 25 year design life. These certifications apply to the tank panels specifically; pump and control panel components are specified separately within the same turnkey contract.
Yes. Coverage is nationwide across the Philippines, including NCR, the rest of Luzon, Visayas, and Mindanao, as well as PEZA and freeport zones such as SBMA, Clark, Cavite, and Batangas. Installation timelines and logistics are scoped per site regardless of location, with the same single-contract process covering tank, pump, and control panel supply, installation, and commissioning.
