General-purpose intake screening for ponds, canals, and sumps.
The Water Box is a general-purpose intake screen system for ponds, canals, and sumps. It features a large screen area and float-valved level control to deliver consistent flow to pumps and pressure filters. Commonly installed upstream of BIG or TIG filters for coarse screening.
High surface area maintains low intake velocity, preventing screen blinding and extending time between cleanings. Handles heavy debris loading effectively.
Self-regulating float valve assembly maintains consistent water level and flow. No external controls or power required—simple, reliable operation.
Built-in overflow ports prevent chamber overfilling during high-water conditions or float valve malfunction. Safe, fail-tolerant design.
Works seamlessly with BIG or TIG pressure filters downstream. Water Box handles coarse screening, pressure filter provides fine filtration.
Select Water Box model based on pump flow requirements. All dimensions in inches.

Materials: Available in mild steel with epoxy coating or 304/316 stainless steel options. All dimensions in inches. H = Height, L = Length, W = Width. Float valve assembly, overflow ports, and large screen surface included with all models. Contact engineering for site-specific sizing and material selection guidance.
Self-regulating float valve maintains consistent water level inside the chamber. As pump draws water out, the valve opens to allow more in, ensuring continuous flow without air entrainment. No external controls or power required.
Built-in overflow ports provide fail-safe protection during high-water conditions or float valve malfunction. Water safely exits chamber before overfilling occurs. Simple, reliable safety feature.
System Design: Water Box filters are typically installed at the water source (pond, canal, sump) with suction line running to pump. The large screen area and low intake velocity prevent debris accumulation and extend cleaning intervals. Pair with BIG or TIG pressure filters downstream for complete coarse-to-fine filtration protection.
| Mesh | Open Area (%) | Equivalent Perf | Typical Use |
|---|---|---|---|
| 30 | 50 | 0.020–0.025 | Intake |
| 60 | 31 | 0.015–0.020 | Micro |
| 80 | 31 | 0.010–0.012 | Drip |
| 120 | 31 | 0.008–0.010 | Fine protection |
For fine bag filtration (1-200 micron), consider Basket with Bag (BWB) filters. Replaceable bag inserts for targeted micron capture and polishing.
Add downstream BIG inline filters for pressure filtration. Water Box handles coarse screening, BIG provides fine polishing with automatic cleaning.
Compact true-inline TIG filters for space-constrained installations. Works downstream of Water Box for secondary polishing.
Our filtration specialist team will help you select the right Water Box model, configure valve and suction sizes, and design a complete intake-to-pressure filtration system for your application.
