Industrial Water Tanks

Durable, Compliant Water Storage for Industrial and Commercial Applications

AllWater Technologies supplies a wide range of industrial water tanks engineered for high-performance water treatment, storage, and monitoring applications. From standard storage tanks to custom WRAS approved tanks and specialist v-notch designs, our solutions are tailored for safe, efficient, and regulation-compliant use across industrial and commercial sectors.

Whether you’re looking for a chemical dosing tank, clean water reservoir, or flow monitoring setup, we provide robust tank systems with fully integrated pipework, control, and access features.

Water Storage Tanks

Clean Water and Process Water Storage

Our standard water storage tanks are ideal for holding process water, RO permeate, softened water, and treated effluent. Manufactured from high-grade polyethylene or polypropylene, these tanks offer excellent chemical resistance and mechanical strength.

Key Features:

  • Capacities: Available from 50 to 30,000+ litres
  • Materials: PE, PP, PVC, or GRP depending on application
  • Fittings: Threaded, flanged, or bespoke connections
  • Mounting options: Freestanding, bunded, skid-mounted, or on steel frames
  • Covers: Removable lids or sealed tops for hygiene and safety

Colour options: Natural, black, or UV-stabilised materials to suit contents and conditions

All tanks are designed for long service life and minimal maintenance. We also supply compatible level sensors, overflow alarms, insulation jackets, and sight glasses as part of a complete tank package.

Our support includes

Telephone & remote diagnostics for rapid fault identification

System troubleshooting and root cause analysis

Planned service visits tailored to your production schedule

Guidance on optimisation, upgrades and retrofit options

Ongoing training and user support post-installation

On-site engineering support from qualified specialists

WRAS Approved Tanks

For applications where contact with potable water is required, we supply WRAS approved tanks manufactured to meet UK Water Regulations Advisory Scheme (WRAS) standards. These tanks are commonly used in:

  • Potable water distribution systems
  • RO permeate and DI water storage
  • Boiler feed tanks
  • Domestic and commercial building services

WRAS approval guarantees that all wetted materials are suitable for use with drinking water and will not introduce taste, odour, or contamination. These tanks are usually supplied with certified fittings, seals, and gaskets and can be provided with documentation for regulatory sign-off.

V-Notch Tanks

Outfall Monitoring and Flow Measurement

V-notch tanks are specialist units designed for open-channel effluent flow monitoring, typically used to support compliance with Environmental Agency ‘consent to discharge’ licenses. These tanks feature a calibrated V-shaped weir that allows for accurate measurement of flow rate based on the water height above the notch.

V-Notch Tank Features:

  • Integrated V-weir: Typically 90-degree or 60-degree angle for volumetric flow calculation
  • Sample access: Open channel design allows for manual or automated sampling
  • Monitoring integration: Compatible with pH probes, flow sensors, temperature monitors, and data loggers
  • Construction: Manufactured from corrosion-resistant polypropylene or GRP
  • Sizes available: From 300 to 3000 litres, or custom-built

These tanks are essential in industries where discharge limits must be carefully monitored and recorded, including food processing, manufacturing, and laboratories.

Tank Materials and Customisation

AllWater supplies tanks in a wide range of materials to suit different chemical, temperature, and mechanical requirements:

MaterialPropertiesTypical Use
Polyethylene (PE)Good chemical resistance, lightweightGeneral-purpose water storage
Polypropylene (PP)Higher temperature toleranceChemical dosing and pH tanks
PVCResistant to acids and alkalisLaboratory and fume applications
GRPStrong and corrosion resistantOutdoor or bunded tanks
Stainless steelHygienic, high temperature and pressureFood/pharma or clean-in-place

Custom fabrication services are available for unusual tank sizes, restricted space, or specialised fittings. Our team will assist with design, specification, and documentation.

Integrated Tank Systems

Many of our tanks are supplied as part of a complete system. This includes:

  • Bunds and containment trays to meet spill regulations
  • Level control and alarms (float switches, ultrasonic sensors, pressure transducers)
  • Inlet/outlet pipework (PVC, ABS, stainless steel)
  • Heaters and insulation for frost protection or process needs
  • Agitators or mixers for chemical dosing tanks
  • Pump integration for automatic refill or discharge
  • Control panels for automated operation and safety interlocks

All systems are pre-tested, labelled, and documented to simplify installation and commissioning.
