Polypropylene rainwater modules connect to form underground storage systems for gardens, buildings and paved areas. Modular construction allows the tank footprint and capacity to be arranged around the project layout.
Choose a lined collection tank for rainwater reuse, an attenuation tank for controlled discharge, or a permeable soakaway system for infiltration. Module dimensions, access arrangements and loading requirements should be confirmed for each project.
PP rainwater harvesting modules connect to create underground tanks for collecting and storing rainwater. With an appropriate impermeable lining, pretreatment and reuse equipment, the stored water can support landscape irrigation and other approved non-potable uses. Module layout and storage volume can be configured to suit the available space.
Stormwater attenuation tanks temporarily hold runoff before releasing it through a designed outlet. Connected PP modules provide a flexible underground storage footprint beneath suitable landscaped or paved areas. Tank volume, lining and discharge control should be selected to match the drainage design and local project requirements.
Soakaway crates provide underground void space for temporary rainwater storage and infiltration into suitable surrounding soil. Connected PP modules are installed with a specified permeable geotextile and drainage connections. Site infiltration testing, groundwater level and setback requirements determine whether this configuration is suitable.
Heavy duty rainwater modules are selected for projects where underground storage must accommodate specified installation and surface loads. The PP modular framework can be configured for lined storage or infiltration applications. Select the tested module grade together with cover depth, backfill and pavement design for the intended location.
Plan your system around collection area, required storage volume and site conditions. Share your drawings, intended use and installation location so that module configuration, lining and connection requirements can be discussed before ordering.
Modular underground units create space for collecting and managing rainwater below landscaped or paved areas. Systems can be configured for harvesting, controlled attenuation or infiltration, depending on the project design and surrounding ground conditions. The modules are one part of a wider system that also needs suitable inlets, outlets, inspection access and surrounding layers.
The intended use determines whether water is stored for reuse, held before controlled discharge, or allowed to infiltrate suitable ground. These functions should be distinguished before selecting a module and its surrounding geotextile or lining system. Suneco New Materials provides product information to help customers compare the available options against their own specifications. The product range shown on this page is a starting point for an enquiry, rather than a substitute for checking the complete design and site requirements.
Available product options include rainwater harvesting modules, stormwater attenuation tanks, soakaway crates, heavy duty rainwater modules. Review the individual product pages for the relevant structure, material and application information. Products with similar names may use different configurations, so identify the exact option required in your enquiry and confirm its details before preparing an order.
When comparing products, check storage volume, site footprint, installation depth, loading conditions and maintenance access. State the required units and tolerances clearly, and identify any drawings or technical requirements that apply. If a specification is still being developed, explain the intended function and the surrounding materials. This helps the product discussion focus on the information that matters to your project instead of comparing headline descriptions alone.
Plan the construction sequence, supporting surfaces and connections before the materials arrive. Keep the selected configuration consistent with the approved project requirements, and confirm how the product will be handled, stored and inspected. Packing arrangements depend on the product form and order quantity. Include the delivery destination, required schedule and any unloading restrictions when requesting transport information. Installation guidance should be considered alongside the project drawings and the requirements of adjacent materials.
To prepare a useful enquiry, send the product name, required specification, estimated quantity and intended application. Add drawings or reference photographs where they explain a connection, dimension or site condition. Our team can review the requested options and confirm the available packing and delivery information for a quotation. Samples, production schedules and order terms should be confirmed for the selected product before procurement. Use the enquiry form to discuss your project requirements with Suneco New Materials.
