Water storage tanks for drainage, sewage and rainwater systems
Water storage tanks support reliable collection, storage and control of water in rainwater, drainage and general liquid storage systems. For Water storage tanks UK projects, practical selection starts with the installation location, required tank format and the accessories needed to control filling, level monitoring and outlet connection. The available product signals cover underground water tanks, above ground tanks, break tanks, plastic storage tanks, polyester tanks and tank accessories for system control.
Drainage tanks UK and Sewage tanks UK requirements can vary by site design, so the tank type should always match the intended system and installation context. Rainwater storage tanks and rainwater harvesting tanks are commonly selected for collection and supply arrangements, while storage tank systems often need valves, switches, covers and level control components to work as intended. If a project specification refers to septic tanks or holding tanks, confirm the product detail and local installation requirements before selecting a tank.
Choosing underground and above ground tank formats
Underground water tanks are suited to buried installation contexts where stored water must be kept below ground. Product names identify black LDPE underground tank variants, including CU, CUV and CHU formats. Visible capacities include 1000 ltr, 1400 ltr and 10000 ltr variants, depending on the model. These underground drainage tanks should be selected with care around excavation, access, connection position and any installation requirements stated in the product data.
Above ground tanks suit installations where inspection and access are important. Product titles identify blue LDPE tank options in vertical, horizontal and square formats, including CV, CHO, CPN, CP and CB types. Visible capacities include 200 ltr, 300 ltr, 500 ltr and 1000 ltr options. Polyester grey tanks and tanks with legs are also listed, with examples such as 180 ltr and 600 ltr variants. Match the tank shape to the available floor space, the inlet and outlet layout, and the required access for maintenance.
Plastic storage tanks and polyester tank options
Plastic storage tanks in LDPE are shown in blue and black versions. Blue LDPE tanks are listed in above ground formats, while black LDPE tanks appear as underground models. LDPE is a practical material choice where the product detail confirms suitability for the intended liquid and installation. Polyester grey tanks provide another tank option, including standard tank formats, tanks with legs and loose covers for liquid tanks.
Several tank products are available in multiple variants. Variant groups indicate that a product family may cover more than one size, format or configuration. Rather than selecting by capacity alone, compare the complete product detail, including shape, orientation, connections and accessory compatibility. Water retention tanks and storage tank systems work best when the tank, controls and fittings are selected as one system rather than separate parts.
Break tanks for rainwater harvesting
Break tanks are available for rainwater harvesting applications. A listed break tank for rainwater harvesting includes male thread connections and a 230 VAC reference in the product title. Break tanks can form part of a controlled supply arrangement, especially where the installation design calls for separation, level control or managed feed into connected equipment.
When selecting break tanks, check the connection size, thread type, electrical reference and installation context against the system design. A break tank should not be chosen only by description. Confirm that the tank, valves, switches and connected components suit the same rainwater harvesting tank arrangement.
Tank accessories for filling, level control and covers
Tank accessories include float balls, float valves, floating foot valves, float switches, level switches, level indicators, pressure controllers, mounting brackets, loose lids and loose covers. These components help complete water storage systems by supporting filling control, level monitoring, pump-related control and tank closure.
Float balls are listed in HDPE and PE versions, including options for slide bars. Float valves appear in brass and plastic versions, with male thread references and pressure ratings such as 3 bar and 5 bar shown in product names. Floating foot valves are listed in brass/PE with hose tail connections and pressure ratings such as 6 bar and 10 bar. Float switches and level switches include 230 VAC references in some product titles, while level indicators and pressure controllers support control and monitoring functions.
Lids and covers should be matched to the relevant tank type and size. Product titles identify loose lids for LDPE tanks and loose covers for polyester liquid tanks. Correct compatibility matters because a cover or lid must fit the tank opening and suit the tank material. For any tank accessory, compare the connection type, thread, hose tail, cable reference, control function and matching tank type before ordering.
Practical selection cues for tank systems
Start with location. Choose underground tanks for buried installation contexts and above ground tanks where direct access is needed. Then confirm the tank material and format. LDPE, polyester, vertical, horizontal, square and legged tank formats all suit different layout needs. Next, confirm capacity using the product variant detail rather than assuming from the product family name.
For rainwater storage tanks, underground drainage tanks or broader storage tank systems, accessories should be selected alongside the tank. A float valve, float switch, floating foot valve, level indicator or pressure controller may be required depending on how the system fills, empties or controls water level. Clear compatibility checks reduce ordering errors and help the installation team work with the right components from the start.
