Field-camp hygiene in welded steel, ready to deploy

Overview

The Sanitary and Septic family covers every hygiene function a deployed camp needs: WC blocks in gents, ladies and accessible variants, shower blocks, laundry blocks, kitchen trailer modules, and the supporting infrastructure of septic holding tanks and fresh-water tanks. Units run stand-alone where there is no mains connection, or hook directly into base water and sewer when there is. The shell is the same 20 ft ISO 1CC envelope used across our other families, which keeps transport, lashing and stacking identical to a dry cube. Internal fit-out is sealed, ventilated and finished to hygienic wet-area surfaces.

Tanax has delivered this family at scale to the Slovak Fire and Rescue Service (HaZZ) as part of a 57-plus unit programme covering sanitary, laundry, material-transport, septik and water-tank containers in RAL 3000 fire-service red, hot-dip galvanised, with a 24-month warranty on the steelwork. The same line builds units that ship to defence bases and emergency-accommodation programmes across the region.

Construction and materials

• Frame: hot-rolled steel, EN 1090-1 EXC2 chain, welded under EN ISO 3834-2.
• Skin: 1.6 mm corrugated steel or PIR sandwich panel where insulation is required for year-round use.
• Wet-area lining: glass-fibre-reinforced sheet or HPL panel sealed at every joint with sanitary silicone.
• Floor: anti-slip R10 finish in WC and shower cells, R11 in the shower tray. Underlay is hot-rolled steel cross-members.
• Shower tray: stainless steel or moulded GRP with central drain and seal.
• Drainage: DN 100 main drain to a gravity manifold on the long side. Internal pipework in PP-H or PVC-U, all joints accessible from a service void.
• Hot water: electric storage boilers, 30 L for hand-wash points, 80 L per shower cell, or a single 300 L 6 kW unit feeding a shower block of four to six heads.
• Ventilation: mechanical extraction over WC and shower cells at a minimum of 8 air changes per hour, with a passive louvered intake. Powered roof fans on the laundry and kitchen variants.
• Electrical: PN-HD 60364 distribution board, 32 A or 63 A CEE inlet, RCBO per circuit, IP44 fittings in wet areas, IP65 outside. LED panels throughout.
• Insulation (heated variant): 100 mm PIR walls and 140 mm PIR roof, 100 mm mineral wool floor where the unit will overwinter on site.
• Doors: 1.6 mm steel external doors with EPDM gasket. Internal cubicle partitions in HPL with anti-vandal hinges and indicator locks.
• Backflow protection: DIN EN 1717 compliant inlet group on the fresh-water side. Mandatory where the unit can be cross-connected to a non-drinking line.
• Surface preparation: ISO 8501 Sa 2.5 in our own blast booth. Two-coat system rated to C3 corrosivity per EN ISO 12944.
• Livery: catalog colours are RAL 3000 (HaZZ red), RAL 5010 (gentian blue) and RAL 7016 (anthracite). Hot-dip galvanised steelwork on request, as supplied to the HaZZ programme.

External envelope and corner-fitting tolerances meet ISO 668 and ISO 1496-1 so the unit can be lifted, stacked and transported on the same chassis as a dry cube. Each unit ships with a unique BIC code, CSC plate, multilingual handover manual and an as-built drawing of the plumbing and electrical loops.

Typical use cases

1. Field camps and forward operating bases. A WC block, a shower block, a 1000 to 2500 L fresh-water tank container and a 3000 to 5000 L septic holding tank cover a 50 to 100 person camp without mains connection. Refilling and pumping run on a scheduled tanker rotation.
2. HaZZ and civil-protection deployments. RAL 3000 sanitary, laundry and tank containers staged at fire-service depots and rolled out to incidents. Stackable so a four-unit village ships on two flatbeds.
3. Construction-site welfare. Three-cubicle WC block plus a laundry or drying-room module. Mains-connected, no holding tanks, lower spec.
4. Emergency accommodation. Sanitary cores serving rows of accommodation cabins. Sized at one shower head per ten occupants and one WC per fifteen, in line with the CZ 25-040 programme template.
5. Police and training facilities. Sanitary cores integrated into the modular accommodation we deliver for ITCC Pezinok and similar training centres under the EU-funded ISF 2021 to 2027 framework.
6. Septic and water-tank infrastructure. Stand-alone tank containers paired with any live-in or sanitary family in the catalog. Specified in litres of holding capacity, not in seats.

Customisation options

• WC block layouts: three-cubicle gents with two urinals, three-cubicle ladies, plus a separate accessible cell to a 1500 mm turning circle.
• Shower block layouts: four to six heads with a central wet corridor and changing benches, or paired single cubicles for privacy-first deployments.
• Laundry module: two industrial washers, two dryers, a folding bench and a chemical store. 32 A CEE inlet, dedicated extraction.

FAQ

Can these units run with no mains connection at all? Yes. The standard self-contained set is a sanitary block plus a fresh-water tank container plus a septic holding tank container. Sized for a 50 to 100 person camp, the cycle runs on a tanker visit every two to four days depending on usage. Below that population a single tank container can carry both fresh and grey water in twin compartments.

What size septic holding tank do I need? For sanitary use we size on 80 to 120 litres per person per day with a minimum of two days of buffer. A 30 person camp on a two-day cycle takes a 5000 L tank. A 15 person field office on a four-day cycle takes a 2000 L tank. We will run the calculation against your headcount and tanker rotation as part of the quotation.

Is the fresh-water side certified for drinking water? Internal pipework, boilers and the inlet group are sourced from suppliers with DVGW or equivalent potable-water approval. Backflow prevention is to DIN EN 1717 on the inlet. Final certification of the installed water for human consumption is a site-level test and the responsibility of the operator once the unit is connected.

Can you build to the HaZZ specification? Yes. We have delivered more than 57 ISO sanitary, laundry, septik and water-tank units to the Slovak Fire and Rescue Service in RAL 3000 livery, hot-dip galvanised, with a 24-month warranty on the steelwork. The same drawings can be re-issued for civil-protection orders in other markets.

What about winter operations? The standard catalog unit is rated for mains-connected use in mild winters. For sub-zero deployment we add 100 mm PIR walls, 140 mm PIR roof, electric trace heating on every external pipe run, frost monitors per circuit and a heated tank jacket on the tank containers. Specify the lowest design temperature at quotation and we will size accordingly.

Can the sanitary core be integrated into a larger accommodation village? Yes. The unit can ship as a stand-alone island or as a sanitary core docked between rows of accommodation cabins from our Office and Living family. Shared service voids and a common low-voltage distribution board let the village run from a single inlet.

How is the unit lifted and moved on site? Each unit is a full ISO 1CC stackable shell with eight forged corner castings. Crane lifting uses standard ISO twistlocks. Forklift pockets are integrated into the base rail on request. On long-term sites the unit usually sits on screw piles, gravel pads or a thin concrete slab. We do not pour foundations, that work belongs with the site contractor.

Where do I send a request for a quotation? Send headcount, deployment duration, mains-connection status and any livery or certification requirements to [email protected]. We return a fixed quote and lead time within 3 to 5 working days for standard configurations.
