Factors to Consider When Choosing a Water Tank Size

Selecting the right water tank size depends on several crucial considerations to match storage capacity with usage demands efficiently.

1. Water Usage Patterns

High water consumption patterns, like frequent laundry or long showers, increase storage requirements. For instance, a household with two people may need approximately 80 litres, but actual needs can vary.

2. Building Supply Rate

A poor mains water supply rate or inconsistent pressure means larger tanks may perform better. If supply is steady, smaller tanks might suffice.

3. Filling Time

Assume a maximum filling time of four hours when flow rate information is not available. This ensures adequate storage replenishment under normal conditions.

4. Location of the Tank

Ground floor tanks fill faster due to higher inlet pressure compared to rooftop tanks. However, rooftop tanks may need larger storage volume to maintain continuous supply.

5. Space Availability

Limited space may constrain tank size options. Compact designs might be essential for buildings with reduced storage areas.

6. Avoiding Oversizing

Oversized tanks risk water stagnation, which reduces quality. Balance needed capacity with practical use to prevent storage issues.

These factors allow us to identify the most suitable size, ensuring optimal performance and longevity of the water tank.

Common Water Tank Capacities

Water tanks are available in various capacities to suit diverse applications. From compact designs for homes to massive solutions for industrial use, understanding common tank sizes helps decide the ideal fit for specific needs.

Small Tanks (Up to 1,000 Litres)

Small water tanks are designed for limited space and minimal storage requirements. Capacities typically start from 4 litres and go up to 1,000 litres. They’re perfect for domestic applications like rainwater harvesting, garden irrigation, or single-room water storage. Examples include compact loft tanks and water butts, which efficiently fit small spaces while offering sufficient capacity for everyday use.

Medium Tanks (1,000 to 10,000 Litres)

Medium-sized tanks cater to both residential and commercial needs. With capacities ranging from 1,000 to 10,000 litres, these tanks are ideal for multi-person households, small businesses, or moderate agricultural use. Horizontal and vertical tanks in this size range provide flexibility and cater to diverse requirements, from storing potable water to supporting operations like car valeting or window cleaning.

Large Tanks (Over 10,000 Litres)

Large water tanks exceed 10,000 litres and are designed for high-demand applications. These tanks are essential for industrial processes, extensive agricultural activities, or large commercial setups. Capacities can go up to 1,000,000 litres, with options like underground tanks or flexible bladder tanks offering scalability and space efficiency. They ensure an uninterrupted supply of water in bulk operations while supporting effective resource management.

Potable vs Non-Potable Water Tanks

Selecting between potable and non-potable water tanks is essential for safe water storage and specific application needs. These tank types differ in their construction, purpose, and compliance with regulations.

Key Differences

Potable water tanks store water fit for human consumption, including drinking, cooking, and cleaning. They conform to strict WRAS (Water Regulations Advisory Scheme) standards and the Water Supply (Water Fittings) Regulations 1999. Constructed with food-grade materials like polyethylene, they prevent bacterial growth and ensure water safety.

Non-potable water tanks are designed for storing water not suitable for drinking. These include uses like flushing toilets, rainwater harvesting, and agricultural irrigation. They don't need WRAS compliance, as the water isn't consumed. However, they're built to securely hold and preserve non-drinking water for various purposes.

Practical Uses for Each Type

Potable water tanks are ideal for households, food preparation areas, and facilities requiring clean water, offering capacities from 4 to 30,000 litres to suit different consumption levels. They're commonly used in homes, offices, and restaurants.

Non-potable water tanks support tasks like watering gardens, cleaning equipment, and livestock hydration. Popular in agriculture, horticulture, and industries with high water demand, they serve as an eco-friendly solution to reduce reliance on mains water.

Customisation Options for Water Tanks

Customisation ensures water tanks meet specific needs for various applications. Our tanks offer versatile options to suit diverse requirements and environmental conditions.

Fittings and Equipment Mounting

Our water tanks accommodate a wide range of fittings and mounting options. Drainage connections, overflow outlets, and inlet fittings can be configured to match usage demands. For equipment like pumps and filtration systems, mounting points offer seamless integration, enhancing tank functionality. Custom placement of inspection hatches and vents can also improve ease of maintenance and operational efficiency. These features cater to applications such as irrigation setups, industrial processes, and domestic water systems.

Material Choices and Durability

We offer tanks crafted from materials tailored to your needs. GRP (Glass Reinforced Plastic) ensures lightweight yet robust construction, ideal for potable and non-potable water storage. For environments requiring enhanced strength, we provide heavier-duty materials with resistance to chemical exposure and UV degradation. These tanks maintain durability in harsh conditions, supporting long-term use in commercial, industrial, and agricultural applications. Insulated options with walls of 25mm, 50mm, or 75mm thickness are available for temperature-sensitive uses.

Delivery and Installation Considerations

Delivery timing varies depending on stock availability and the nature of the order. Standard orders are generally delivered within a specified timeframe indicated on the product page. Custom orders may require additional time as they're tailored to specific needs. If any delay occurs, we notify customers promptly via email.

Separate deliveries might happen when multiple items are ordered, as stock items may be located in different warehouses. Unless otherwise stated, all deliveries are made to kerbside, and larger items may necessitate customer offloading. It's essential to have someone present to inspect and sign for the goods upon delivery. Signing confirms the packaging is intact; any damage reported afterward may result in customers covering collection or redelivery costs.

For parcels to be left in a safe place without supervision, customers assume full risk. Damage or theft under such circumstances is not covered. Clear communication and preparation ensure a smoother delivery process, especially for large-scale water tanks.

Conclusion

Choosing the right water tank size is essential for efficient storage and resource management. By understanding your specific needs and considering factors like usage patterns, space availability, and water supply, you can ensure optimal performance and longevity. Whether it's a small domestic tank or a large industrial solution, the right choice supports both practicality and sustainability.

Customisation options and material durability further enhance functionality, while proper planning for delivery and installation ensures a seamless experience. With careful consideration, the perfect water tank can meet your requirements and provide long-term value.
