Secondary containment for a sprinkler-fed indoor storage area is a civil and fire-engineering design task: curbs, sumps, or floor drainage sized to hold the sprinkler system's design discharge, per the project's governing fire code (IFC 5004.2.2.3 is one such reference). TankSmith's scope is the water side of that system, the fire reserve tank (1,000 to 500,000 liters) and booster pump feeding the sprinkler network, sized and installed in 5 to 14 days.
What Secondary Containment Means for an Indoor Fire Sprinkler Storage Area
Secondary containment is a design provision that stops water discharged during a sprinkler activation, and anything it mixes with, from leaving the storage area uncontrolled. In practice this is built as curbs, raised sills, floor slope toward a sump, or a dedicated drain sized for the sprinkler system's design discharge rate over its design duration. IFC 5004.2.2.3 is one of the code references that sets out when and how this containment is required for indoor storage areas, alongside material-specific requirements that depend on what is stored in the room. Getting the containment sizing right is a function of the sprinkler design density, the room's hazard classification, and the facility's drainage plan, which is why it is handled by a licensed fire protection engineer or civil engineer working from the project's approved fire protection plans, not by a tank or pump supplier. TankSmith does not design, size, or certify secondary containment structures, and this page is not a substitute for a code review by a licensed professional on your specific project. What TankSmith does is supply and install the water storage and pumping equipment that the sprinkler system draws from, which is a separate but connected part of the same fire protection system. For any project working through IFC 5004.2.2.3 compliance, the containment design and the water supply sizing typically happen in parallel, coordinated through the same fire protection plan set, so it helps to bring in both scopes early rather than sequentially.
Where TankSmith's Scope Starts: the Fire Reserve Tank Feeding the Sprinkler System
Once a project's fire protection engineer has set the required fire reserve volume, TankSmith supplies and installs the modular tank that holds it. Our fire reserve tanks run from 1,000 liters up to 500,000 liters per system, built in FRP (fiberglass reinforced plastic) bolted panels, GRP/SMC, hot-dip galvanized (HDG) steel, or stainless steel 304/316, depending on site conditions, water quality requirements, and budget. For fire reserve applications specifically, the material choice usually comes down to design life and site access rather than potable-water certification, since the reserve volume is dedicated to fire suppression rather than drinking water, though WRAS-certified panels and NSF-compliant liners are available where the same tank also serves a potable or process-water role. Every tank carries a 3-year panel warranty with a 20 to 25 year design life, and the modular bolted-panel construction means the tank can be sized to the exact reserve volume the fire protection plan calls for, rather than rounding up to the nearest stock size. This matters on sites where the containment design and the fire reserve volume are tightly coupled, such as warehouses and manufacturing facilities in PEZA and freeport estates (SBMA, Clark, Cavite, Batangas), where available footprint and drainage routing are both constrained.
Booster Pump and VFD Control for Sprinkler-Fed Systems
The fire reserve tank only supplies water if the pump system delivering it to the sprinkler network is sized and controlled correctly. TankSmith's booster pump systems use vertical multistage centrifugal pumps from the CDL/CDLF series, ranging from 0.37 kW to 200 kW, built in SS304, paired with VFD duplex control panels running Inovance VFDs. These panels are IP54-rated, monitor pressure feedback, and auto-alternate between pump units, which keeps a sprinkler-fed system responsive across variable demand without one pump carrying the full duty cycle continuously. For a secondary containment conversation specifically, the pump system is relevant because the sprinkler design discharge rate and duration, the numbers the containment sizing is based on, are a function of the pump's delivered flow and pressure, not just the tank volume. A pump system that cannot sustain the designed flow and pressure undermines both the sprinkler performance and the assumptions the containment design was built on. TankSmith supplies the tank and the pump system as a single contract, mechanical, electrical, and commissioning, so the two components are sized against the same design numbers from the start rather than reconciled after installation.
Sizing the Tank and Pump to Match the Project's Containment and Code Requirements
Coordinating secondary containment design with fire reserve tank and pump sizing works best when both scopes reference the same source numbers from the fire protection plan: design discharge rate, discharge duration, and the required fire reserve volume. TankSmith's typical turnaround for a fire reserve tank and pump install, once those numbers are confirmed, is 5 to 14 days for systems between 20,000 and 500,000 liters, with the exact timeline depending on capacity and how ready the civil works (foundation, access, drainage tie-in) are on site. Because the containment structure (curbs, sumps, drains) and the tank foundation are often built by the same civil contractor, sequencing the containment pour before or alongside the tank foundation avoids rework later. TankSmith coordinates the tank and pump installation schedule around the site's civil readiness rather than working to a fixed calendar date, which keeps the water-storage side of the project from becoming the bottleneck on a containment-driven schedule. For PEZA and freeport facilities in particular, where fire protection plans go through an additional layer of estate-authority review, having the tank and pump specification finalized early helps that review move without a pending equipment spec holding it up.
Materials and Certifications for Fire-Protection Water Storage
Material choice for a fire reserve tank in a containment-regulated facility usually comes down to design life, corrosion resistance, and how the tank integrates with the site's drainage and containment layout. TankSmith offers FRP (fiberglass reinforced plastic) bolted panels, GRP/SMC, hot-dip galvanized (HDG) steel, and stainless steel 304/316, each manufactured by an ISO 9001 certified partner factory. Where a tank also serves a potable or process-water function alongside its fire reserve role, WRAS-certified panels (rated for potable water up to 65C) and NSF-compliant liners are available, and panels are TUV SUD tested. The 3-year panel warranty and 20 to 25 year design life apply across the material range, so the choice between materials is a site-condition and budget decision rather than a durability tradeoff. For facilities where the containment design assumes a specific tank footprint or height (common in retrofit projects with constrained ceiling clearance or tight access), the modular bolted-panel format lets the tank be built to match that footprint rather than forcing a containment redesign around a fixed tank size.
Who to Call for What: Fire Protection Engineer vs. Tank and Pump Supplier
A project working through IFC 5004.2.2.3 or an equivalent secondary containment requirement needs two separate scopes handled correctly: the containment structure itself (curbs, sumps, drainage, sized and certified by a licensed fire protection or civil engineer), and the water storage and pumping equipment that feeds the sprinkler system those containment provisions protect. TankSmith is the second scope, not the first, and does not claim licensing or design authority over containment structures. Within that water-storage and pump scope, TankSmith's single-team accountability model (supply, install, and commission the tank and the pump system under one contract) is built for facilities where fire reserve, pump reliability, and installation timeline all need to line up against a fire protection plan's numbers. This applies across the verticals TankSmith serves that are most likely to carry containment requirements: warehouse and manufacturing facilities, hospitals and clinics needing code-compliant fire reserve, and PEZA, SBMA, Clark, Cavite, and Batangas industrial estate projects, which often have the most detailed fire protection plan review of any facility type TankSmith works with.
Frequently Asked Questions
No. Secondary containment design is handled by a licensed fire protection engineer or civil engineer working from the project's approved fire protection plan, not by TankSmith. TankSmith supplies and installs the fire reserve water tank (1,000 to 500,000 liters) and the booster pump system that feeds the sprinkler network the containment protects. If your project needs IFC 5004.2.2.3 or equivalent containment compliance, bring in a licensed fire protection engineer for that scope and TankSmith for the tank and pump sizing, ideally at the same time so both reference the same design numbers.
It is a provision under the International Fire Code's indoor storage requirements addressing secondary containment, structures like curbs, sumps, or drainage that keep sprinkler discharge and whatever it mixes with inside the storage area rather than spreading uncontrolled. The exact requirements that apply to a specific room depend on what is stored there and the room's hazard classification. Because code application varies by project and jurisdiction, TankSmith is not the source for a compliance determination on this code section; that call belongs to your project's licensed fire protection engineer.
TankSmith's modular tank systems range from 1,000 liters to 500,000 liters per system, available in FRP (fiberglass reinforced plastic) bolted panels, GRP/SMC, hot-dip galvanized steel, or stainless steel 304/316. Each carries a 3-year panel warranty with a 20 to 25 year design life. The tank size for a fire reserve application is set by your fire protection plan's required reserve volume, which TankSmith builds the modular tank to match rather than rounding up to a fixed stock size.
Typical turnaround is 5 to 14 days for systems between 20,000 and 500,000 liters, depending on capacity and how ready the site's civil works (foundation, access, drainage tie-in) are. TankSmith supplies, installs, and commissions the tank and pump system under one contract, mechanical, electrical, and commissioning, so scheduling is coordinated as a single project rather than split across separate tank and pump vendors.
TankSmith uses vertical multistage centrifugal booster pumps from the CDL/CDLF series, 0.37 kW to 200 kW, built in SS304, paired with VFD duplex control panels running Inovance VFDs. The panels are IP54-rated with pressure feedback and auto-alternation between pump units, which keeps delivery consistent across variable sprinkler demand without one pump carrying the full load continuously.
Yes. TankSmith serves warehouse and manufacturing facilities in PEZA and freeport industrial estates, including SBMA, Clark, Cavite, and Batangas, alongside nationwide coverage across NCR, Luzon, Visayas, and Mindanao. These estate projects often carry additional fire protection plan review, so having the fire reserve tank and pump specification finalized early helps keep that review from stalling on a pending equipment spec.
