For a fire-water tank, volume, protected reserve, pumps, fittings and access are established by the fire-safety scenario/design, then translated into the right PEHD configuration.
Quick specification table
| Existing Weldplast data | Made-to-order PE-HD/PP-H tanks, mostly up to ~35 t max (≈35 m³); buried/above-ground installationOwner data reconciles in-house capacity to ~35 t; each tank is made to order, in any dimension required by the project. |
|---|---|
| Public water projects | 8,000 L Bucharest hospital, 20,000 L drinking water, 35,000 L undergroundPortfolio examples; fire-water use is confirmed for each project. |
| Norms to verify | P118/2 and, where project specs mention it, NP 086Exact application, volume and scenario are set by the fire-safety design. |
| Fittings | Fill, pump suction, overflow, drain, vent, levelPositions depend on pump room and operation. |
The protected reserve comes from design
The fire reserve must be protected from normal consumption and aligned with the fire-flow and duration required by the scenario.
If the tank has another use too, request separation between usable volume and protected reserve plus the automation detail.
What to clarify before fabrication
Send the required volume, dimensions imposed by the site, fitting elevations, pump room, maintenance access, burial conditions and material requirements.
Fire-safety compliance is confirmed with the scenario, design and model documents. The fire-water scenario and volume come from the approved design.
Fire-water tank checklist
- 1Total volume and protected fire reserve from the design.
- 2Fire flow/duration and type of system supplied.
- 3Suction, fill, overflow, drain, vent and level fittings.
- 4Buried or above-ground installation, access and frost protection.
- 5Sensor, automation and pump-room requirements.
- 6Current norm to cite: P118/2-2013, as amended; NP 086-05 was replaced/abrogated when Order 2463/2013 entered into force, so cite NP086 only if an older project explicitly requires it. Other documents remain scenario/project-specific.
Short FAQ
Can any PEHD tank be used for fire water?
It can be used when the design confirms volume, fittings, pumps, access and fire-safety requirements for the selected model.
Does Weldplast have water projects?
Yes, the public portfolio includes 8,000 L, 20,000 L, 27 m³ and 35,000 L water tanks. For fire-water use, confirmation is made per project.
Which norms are cited?
P118/2 is the usual norm for fire-extinguishing installations; NP 086 appears in older specs/projects. Exact application remains with the designer.
