Potable Water Tanks
Hygienic water storage for residential, commercial and institutional building water supply.
Store treated water safely and coordinate the tank with the building water supply design. LeAqua can support modular potable storage and coordinated supply packages through the agreed project scope.

Storage. Pressure. One coordinated specification.

What is a potable water tank?

A potable water tank stores treated water for drinking, food preparation, washing and other building uses where water quality must be protected. Capacity, turnover, construction, access, venting, overflow and cleaning arrangements must match the building water supply design and the requirements at the project location.
LeAqua can coordinate modular storage with booster pumps and controls within the agreed project scope. The proposal should start with the demand profile, effective storage volume, water-contact requirements and site layout, so the tank can be reviewed as part of the complete water supply system.
Tank or coordinated supply
Choose the storage arrangement that fits your building
The right scope depends on whether the tank is specified separately or coordinated with booster pumps, controls and the building water supply system.

Tank package
Standalone potable water tank
For projects with a separate booster set, pump room or independently designed mechanical package.
- Hygienic internal surfaces and access for inspection
- Inlet, outlet, overflow, drain and vent arrangements
- Support and foundation interface requirements
- Material traceability and water-contact documentation within the agreed scope
Coordinate early: inlet and outlet levels, turnover target, service clearances and the responsibilities of the tank and pump suppliers.

Coordinated system
Tank and building water supply package
For projects that need storage, pressure boosting and controls planned together within one coordinated layout.
- Storage and pump-room arrangement
- Booster pumps and pressure-control equipment as specified
- Pipework and control interfaces within the agreed package
- Water quality or level monitoring defined in the project specification
Coordinate early: pump duties, pressure setpoints, power supply, access and the boundary between factory supply and site work.
Define the full supply boundary. Building pipework, power connections, installation, cleaning, disinfection and commissioning should be allocated explicitly in the quotation. An integrated package does not automatically include every site activity.

How to specify a potable water storage tank
Tank volume is only one input. Establish the demand profile, turnover target, water-contact requirements and site interfaces before comparing configurations.
| Design input | What to establish | Why it affects the tank |
|---|---|---|
| Demand profile | Occupancy, peak demand, replenishment source and expected daily use. | Sets the storage and refill basis; building area alone does not determine tank volume. |
| Effective storage & turnover | Usable volume, operating levels, refill time and target turnover for the stored water. | Helps balance reserve capacity with water freshness and operating continuity. |
| Water-contact materials | Material grade, lining or resin, seals, fittings and required documentation. | The wetted materials must suit the water-contact and acceptance requirements. |
| Inlet, outlet & hygiene | Inlet and outlet levels, venting, overflow, drain, access and cleaning arrangements. | Supports cleanability, inspection and reliable connection to the building system. |
| Site & structural conditions | Footprint, foundation, indoor or outdoor location, access, wind and seismic inputs. | Determines the layout, supports and installation method. |
| Project acceptance | Applicable local requirements, drawings, inspections, testing and approval documents. | Allows the proposed configuration to be checked before procurement. |
Select the material for the specified water service
Stainless steel, GRP and composite sectional tanks are product options to evaluate. Suitability depends on water-contact requirements, exact construction, water conditions and project acceptance.
Stainless steel
Review the grade, welded or bolted construction, water chemistry, fabrication details and maintenance access.
GRP / FRP
Review the panel system, water-contact resin or lining, temperature limits, support arrangement, seals and project acceptance requirements.
Composite sectional tanks
Confirm the panel build-up, water-contact layer, external protection and the required structural configuration.
Structural form is a separate choice from material. Explore the double-sided arc-ribbed tank design where its configured layout suits potable storage.
Standards & project acceptance
Confirm water-contact and project requirements before selecting equipment

Drinking-water storage requirements vary by project location. Identify the applicable water-contact, building-plumbing, hygiene and inspection requirements before selecting a tank.
Share required material grades, approval documents, inspection records and cleaning or disinfection procedures before a configuration is proposed.
A general reference to potable water use does not establish certification or approval of a particular product. Review the proposed tank, water-contact materials and supporting documents with the project designer or authority having jurisdiction.
Typical building applications
Potable water storage across building applications
Potable storage may support residential buildings, schools, hospitals and public facilities. The correct arrangement depends on demand pattern, turnover, hygiene requirements and site conditions. The images below are layout placeholders, not delivered project records.

Residential and mixed-use buildings
Residential water supply
Potable storage coordinated with a building water supply system and booster equipment.
Application example — confirm capacity from the project demand profile.

Schools, hospitals and public buildings
Institutional water supply
Storage, pressure boosting and water quality controls should be coordinated around occupancy and service requirements.

Before you order
Potable water tank buying questions
Can one tank serve both fire protection and potable water?
Only where the applicable design and approval requirements permit it. The arrangement must preserve the required fire reserve, protect water quality and address outlet levels, controls and maintenance. Have the fire and building-services designers confirm the arrangement before choosing a shared tank.
What determines the price of a potable water tank?
Effective capacity, dimensions, panel material, water-contact requirements, connections, installation conditions and the agreed supply scope all affect the quotation. A tank-only price should not be compared directly with a package that also includes pumps, controls, freight or site services.
What documents should be checked for potable water storage?
Include the project location and required water-contact or hygiene criteria in the initial enquiry. Check material traceability, product drawings, inspection records and any required approval route for the proposed tank.
Can an existing potable water tank be replaced?
A replacement can be evaluated against the existing capacity, foundation, access, pipe connections and water-quality requirements. Plan isolation, cleaning, disinfection and temporary supply with the responsible project team before work starts.

Tell us what your potable water system needs
Share the information you already have. It helps define the tank configuration, supply scope and documentation needed for a useful proposal.
- Project location and applicable water-contact requirements
- Demand profile, required storage volume and turnover target
- Available footprint, height and installation conditions
- Water source, treatment status and temperature or corrosion exposure
- Tank-only or tank-and-pump scope; specified flow and pressure if available
- Required delivery schedule and site-service scope
If the building water supply design is still being developed, identify which inputs are provisional so they can be reflected in the proposal.
