GRP Water Storage Tanks for Industrial & Manufacturing Sites
Cold water and process water storage systems for factories, manufacturing plants, warehouses, logistics sites, utilities, and industrial facilities.
Tricel Water supplies high-capacity GRP water storage tanks for industrial applications including manufacturing plants, energy and utility sites, food and beverage processing, chemical industries, construction, and infrastructure projects. The existing industrial page identifies use cases such as cooling systems, processing lines, sanitation, turbine cooling, dust suppression, fire suppression, treated water, process water, and non-potable liquid storage.
Key facts at a glance
High-capacity
Industrial facilities may need large stored volumes for process supply, washdown, cooling, or fire suppression.
Continuity
A loss of stored water can affect production, cleaning, cooling, or site operations.
Corrosion-resistance
GRP is suitable where steel corrosion, humidity, or harsh site conditions are concerns.
Sectional construction
Modular panels help where tanks must be assembled inside restricted plant rooms or factory service areas.
Duty separation
Industrial sites may need separate tanks for potable supply, process water, washdown, fire reserves, or treated water.
1k–1M+ L
Industrial GRP tanks range from 1,000 litres to over 1,000,000 litres, depending on project requirements.
01
Resilience infrastructure
Water storage for industrial sites where supply interruption can disrupt operations
Industrial and manufacturing buildings often need water for more than domestic use. A factory may require stored water for production lines, cleaning, washdown, cooling, welfare facilities, and fire protection. A warehouse may need cold water storage for staff facilities, sprinkler reserves, cleaning, and site operations. Energy, utility, and chemical sites may also require stored water for process, cooling, treated water, or non-potable duties.
Because these systems may support operations as well as building services, tank specification should consider not only capacity, but also water type, usage pattern, duty separation, plant access, maintenance, and continuity of supply.
Sectional GRP tanks are suitable for many industrial projects because they can be configured around site space, access constraints, capacity requirements, and the distinction between potable, non-potable, process, and fire suppression storage.
Key Message
In industrial and manufacturing settings, tank design must reflect the actual duty of the water system, not just the building footprint.
Poor specification can lead to insufficient water supply during production or cleaning cycles, unclear separation between potable, process, non-potable, and fire water, oversized tanks with poor turnover where potable water is stored, inadequate access for inspection, cleaning, or maintenance, installation problems in restricted plant rooms or operational factories, increased operational risk if a single tank failure affects production, poor alignment between storage, booster sets, and process requirements.
02
Water storage duties
Industrial and Manufacturing applications
Water storage requirements differ significantly across manufacturing, logistics, food processing, energy, and chemical environments. The dominant risks and specification priorities vary by water duty, operational profile, and site conditions.
GRP Tanks
Manufacturing plants
Manufacturing plants may require stored water for production lines, process support, sanitation, washdown, cooling, and staff facilities. Tricel’s industrial page identifies manufacturing plants as a key application, including consistent water supply for cooling systems, processing lines, and sanitation.
Common specification considerations:
- Process water demand
- Production shift patterns
- Cleaning and washdown cycles
- Cooling system requirements
- Welfare and potable water supply
- Duty separation between potable and non-potable systems
- Maintenance access without disrupting production
- Booster set integration
GRP Tanks
Warehouses and logistics facilities
Warehouses may have lower process water demand than factories, but still require reliable cold water storage for welfare facilities, cleaning, fire suppression, and sometimes vehicle washdown or site services.
Common specification considerations:
- Staff welfare facilities
- Washroom and canteen demand
- Cleaning and site maintenance water
- Sprinkler or fire suppression storage
- Large roof or external plant areas
- Limited internal plant space
- Operational access routes for maintenance teams
GRP Tanks
Food and beverage processing
Food and beverage facilities require careful consideration of hygiene, cleaning, potable water suitability, process demand, and plant maintenance. Tricel’s industrial page lists food and beverage processing as a relevant sector and refers to clean, secure water storage for hygiene and operational requirements.
Common specification considerations:
- Potable water suitability where required
- Cleaning-in-place or washdown demand
- Process water demand
- Separation between potable, treated, and non-potable systems
- Access for inspection and cleaning
- Temperature and hygiene management
GRP Tanks
Energy and utility sites
Energy and utility sites may require water storage for turbine cooling, dust suppression, site services, and fire suppression. These uses are identified on Tricel’s industrial page.
Common specification considerations:
- Cooling water demand
- Dust suppression
- Fire suppression reserves
- Outdoor installation conditions
- Large capacity requirements
- Site resilience and continuity planning
GRP Tanks
Chemical and process industries
Chemical and process environments may require tanks for treated water, process water, non-potable liquids, or site service water. Tricel’s industrial page identifies chemical industries as a use case for treated water, process water, and non-potable liquid storage.
Common specification considerations:
- Chemical compatibility
- Treated water or non-potable storage
- Secondary containment requirements, where applicable
- Separation from potable water systems
- Access for inspection and maintenance
- Site-specific risk assessment
03
Material selection
Why GRP is suitable for industrial water storage
GRP (glass-reinforced plastic) has properties that make it suited to the demanding conditions found on industrial and manufacturing sites — where corrosion, humidity, operational constraints, and access restrictions may all affect the specification.
GRP Tanks
Corrosion resistance
GRP does not rust, which makes it suitable for many industrial environments where humidity, external exposure, or corrosive atmospheres may affect other materials. Tricel’s industrial page identifies corrosion resistance as a core feature of GRP industrial tanks, including suitability for chemical exposure and harsh environments.
GRP Tanks
Low maintenance compared with corrosion-prone materials
GRP avoids many of the rust-related issues associated with steel tanks. The Tricel infrastructure reference page describes GRP as impervious to rust and corrosion, while noting that galvanised steel protection can degrade at cut edges, fixing points, and mechanically damaged areas.
GRP Tanks
Modular construction for restricted access
Industrial sites often have awkward service areas, existing plant, narrow access routes, or operational constraints. Sectional GRP tanks can be assembled from panels on site, making them suitable where a one-piece tank would be impractical.
GRP Tanks
Capacity flexibility
Tricel’s industrial page states that tanks can be supplied from 1,000 litres to over 1,000,000 litres and that both one-piece and sectional designs are available to suit site requirements, including space restrictions and access limitations.
GRP Tanks
Optional insulation, heaters, and accessories
Industrial sites may require temperature control, frost protection, external installation features, or specific fittings. Tricel’s industrial page lists optional insulation, heaters, and accessories among available features.
04
Regulatory framework
Specify by water duty and risk profile
Industrial water storage specification should begin by identifying the water duty. Each duty has different material requirements, separation obligations, and maintenance responsibilities. Mixing duties — particularly potable, process, and fire reserve — in a single unplanned tank is one of the most common causes of non-compliance on industrial sites.
Where water is intended for drinking, food production, or welfare facilities, the tank and fittings must be suitable for potable water contact under the relevant UK water fittings framework. For GRP sectional cold water tanks, BS EN 13280 applies as the product standard for above-ground cold water storage tanks. Where fire suppression storage is required, BS EN 12845 is relevant for fixed automatic sprinkler systems.
Potable water
Where water is used for drinking, food production, or welfare facilities, the tank and fittings must meet WRAS approval requirements and relevant water fittings regulations.
Process Water
Used in manufacturing lines or treatment processes. Compatibility between the stored water type and tank materials should be confirmed. Separate from potable supply.
Cooling Water
Supports cooling systems and process temperature control. Sizing should account for peak cooling load and the relationship with mains refill rate and process schedule.
Washdown water
Used for cleaning and sanitation in production environments. Demand peaks around cleaning cycles and shift changeovers. Must be separated from potable supply where applicable.
Treated Water
Process or non-potable site applications where water has been chemically or physically treated. Confirm tank material compatibility and outlet fittings before specification
Non-potable storage
General site service water not intended for drinking or food contact. Must be clearly identified and separated from potable systems in both pipework and labelling.
Fire suppression reserve
Dedicated reserve for sprinkler or fire protection systems. Must remain available for fire protection duties and not be accessible for normal production or washdown demand.
Dust suppression
Used on energy, utility, and construction sites for dust control. Typically non-potable; confirm site-specific requirements and seasonal demand variation.
Temporary construction water
Site water supply during construction or infrastructure projects. Typically temporary; confirm duty, volume, source, and access before specifying the tank format.
05
Capacity calculation
Tank sizing for industrial and manufacturing sites
Industrial tank sizing should consider water duty: potable, process, cooling, washdown, treated, or fire reserve, peak flow requirements, daily or shift-based water usage, production schedules, cleaning cycles, cooling loads, mains refill rate, required storage duration, booster set or pump requirements, fire suppression reserve requirements, maintenance access and downtime tolerance, need for compartmentalisation or duty/standby storage.

Tank configuration options
Selecting the correct GRP tank format
Tricel’s industrial page states that both one-piece and sectional tank designs are available to suit site requirements, including space restrictions and access limitations.
One-piece GRP tanks
Profile
One-piece tanks may suit smaller industrial applications where there is enough access to bring the tank into position.
Best suited for: Smaller warehouse facilities; compact plant rooms with clear access; welfare or break tank applications; fast replacement where access allows.
Two-part tanks
Profile
Two-part tanks may be useful where access is restricted but a fully sectional system is not required.
Best suited for: Refurbishment projects; restricted access service areas; factory plant upgrades; sites where one-piece access is not possible.
Sectional GRP tanks
Profile
Sectional tanks are suited to larger capacities, restricted access routes, or projects requiring custom dimensions.
Best suited for: Large factories; warehouses and logistics hubs; energy and utility sites; food and beverage processing; fire suppression storage; basement, rooftop, or internal plant room installation.
Totally Internally Flanged
Profile
TIF tanks can support projects where side access is restricted and the tank must be installed close to walls or other plant.
Best suited for: Constrained factory plant rooms; retrofit sites; service corridors or basement plant rooms; industrial buildings with limited clearance.

08
Implementation
Installation and maintenance access
Industrial sites often have existing plant, live operations, restricted access, external installation areas, and structural constraints. The tank should be specified after reviewing installation access, operational clearances, foundations, floor loading, pipework, and maintenance needs — not only after confirming the required capacity.
Access routes should be assessed before procurement, including doorways, corridors, stairways, lifts, service hatches, roof openings, and floor or platform loading. A filled cold water storage tank imposes a significant load; a structural engineer must confirm floor loading capacity for large tanks. Foundation levelness is the leading cause of premature sectional tank joint failure — the permissible deviation is typically ±2 mm over the full footprint.
Water Duty
Confirm the intended use — potable, non-potable, process, treated, cooling, washdown, or fire reserve — before selecting tank type and materials
Floor loading and foundation
Structural floor load capacity confirmed by a structural engineer for large tanks; foundation level within ±2 mm over full footprint
Insulation and frost protection
For outdoor, roof, or unheated plant room installations, confirm whether insulation, trace heating, or frost protection is required for the stored water duty
Access route
Assess clear opening dimensions at every doorway, corridor, stairway, and hatch from delivery point to installation location before procurement
Headroom and clearance
Adequate height above the tank for lid panels; sufficient clearance on all sides for maintenance, cleaning, and inspection access
Fire suppression reserve
Confirm whether a separate fire suppression reserve is required; if so, confirm duty separation from all process, washdown, and potable water systems

Common questions
Frequently Asked Questions
What are industrial water storage tanks used for?
Industrial water storage tanks can be used for process water, factory supply, cooling systems, sanitation, washdown, warehouse welfare facilities, treated water, non-potable storage, dust suppression, and fire suppression. Tricel’s industrial page lists manufacturing, energy and utilities, food and beverage processing, chemical industries, construction, and infrastructure as key industrial use cases.
Are GRP tanks suitable for manufacturing sites?
Yes. GRP tanks are suitable for many manufacturing sites because they are corrosion-resistant, available in large capacities, and can be supplied in sectional form where access is restricted. Final suitability depends on the stored water duty, site conditions, and any process-specific requirements.
Can GRP tanks store process water?
GRP tanks can be used for many process water applications, subject to the stored liquid, temperature, chemical compatibility, fittings, and site-specific requirements. For chemical or treated water duties, compatibility should be confirmed before specification.
What size industrial water tank is required?
Tank size depends on water duty, peak flow, daily or shift-based usage, refill rate, storage duration, process requirements, fire reserve requirements, and available space. Tricel’s industrial page states that industrial GRP tanks can range from 1,000 litres to over 1,000,000 litres.
Are industrial GRP tanks suitable for potable water?
They can be suitable for potable water where the tank, materials, fittings, and installation are specified for drinking water use. Tricel’s industrial page states that tanks are manufactured to meet WRAS approval standards where applicable.
Should fire suppression water be stored separately from process water?
Fire suppression reserves should be assessed separately from normal site, process, or potable water demand. Where sprinkler standards apply, the fire reserve must be protected so it remains available for fire protection duties.
