Collection: Water Feature Reservoirs and Bases

Water Feature Reservoirs and Bases

Water feature reservoirs and bases form the hidden foundation beneath many self-contained water features, bubbling rocks, drilled stone features, decorative bowls, and pondless waterfalls. These underground sumps and support grids store water below ground level while providing a stable platform for the feature itself, helping to create a clean, professional finish with easy access for pumps and maintenance.

Our range includes heavy-duty plastic reservoirs, galvanised steel support grids, complete reservoir and grid kits, and specialist spillway and watercourse systems from trusted brands including Oase and Eastern Connections. Whether you are building a compact bubbling feature or a larger pondless waterfall installation, these systems are designed to provide reliable water storage, strong support, and efficient water return.

• Creates a hidden underground water storage area for self-contained water features
• Strong support grids designed for stone, slate, pebble, and decorative feature installations
• Suitable for bubbling rocks, drilled stones, bowls, columns, and pondless waterfalls
• Inset access covers allow easier pump inspection and maintenance
• Available in a range of sizes, shapes, and capacities for different installations
• Compatible with pumps, auto-fill kits, spillways, and water blades

Our Plastic Reservoir and Metal Grid Kits provide a simple all-in-one solution for many garden water features. These systems combine a durable underground sump with a galvanised support grid and removable access hatch, making them ideal for both new installations and feature upgrades. Round and rectangular options are available in capacities from compact 60 litre systems through to extra-large reservoirs suitable for larger decorative features and stream collection areas.

We also supply separate replacement metal grids and specialist Oase water feature reservoirs for more advanced installations. Many of these systems are designed to integrate with spillway boxes, waterfall blades, pondless waterfall grids, and auto top-up systems, allowing more flexible water feature designs with reduced visible water areas.

For pondless waterfall and stream projects, reservoir systems can act as underground collection chambers where water is recirculated back to the top of the feature. This approach helps reduce exposed standing water while still creating the sound and movement of a traditional waterfall or stream.

When selecting a water feature reservoir or base, consider the overall size and weight of the feature, the amount of water movement required, and how accessible the pump will need to be for maintenance. Larger or taller features generally benefit from increased water capacity and stronger support grids, while compact reservoirs are often suitable for smaller bubbling stones and decorative bowls.
