Trimble WM-Drain is a comprehensive water management software solution designed for drainage contractors and agricultural engineers tasked with designing, surveying, and installing subsurface tile drainage systems. The software combines advanced hydrologic analysis, GPS-based field survey tools, and machine guidance capabilities to ensure drainage systems are engineered correctly and installed with precision for maximum long-term performance.
Professional drainage contractors rely on WM-Drain's watershed delineation and flow analysis features to understand surface and subsurface water movement across properties. The software models rainfall runoff, determines optimal drainage system layouts, and calculates pipe sizing for design specifications that prevent waterlogging and improve field productivity. GPS-based survey integration allows field crews to capture existing topography, tile locations, and outlet conditions directly into the design model, ensuring designs reflect actual site conditions rather than assumptions.
Machine guidance for trenching and plow operations represents a major competitive advantage for contractors using WM-Drain. Once design grades and centerlines are established in the software, operators receive real-time guidance—either through lightbar displays or steering automation—ensuring trenches and tile lines follow design specifications precisely. This guidance eliminates grade errors, reduces rework, and delivers consistent quality that contractors can document and guarantee to clients. The precision guidance also reduces the physical effort and skill variation required from equipment operators, making crews more productive and less fatigued.
WM-Drain exports design data to standard CAD and GIS formats, enabling seamless integration with engineering workflows, municipal records, and environmental compliance documentation. Cloud storage keeps project files accessible from the office and field, while automatic backup ensures no data loss from equipment failures or unexpected issues.
Contractors also use WM-Drain for client communication and project documentation. Visual representations of drainage design, as-built surveys showing actual installed locations, and performance data create professional deliverables that justify project costs and establish your expertise with future customers.
Express Tools provides WM-Drain software sales, configuration, training, and ongoing support for drainage contractors. We help you implement efficient workflows, integrate with your field equipment, and build the operational practices that drive profitability.
