Water Systems Bench
Plan, size and verify water systems from source to use.
About Water Systems Bench
Interactive tools, guides and references for pumps, wells, storage and rainwater. Build duty points, check yield and simulate supply with transparent methods.
Water Systems Bench functions as a hands‑on engineering system which enables users to create water systems and determine their dimensions and validate their functionality. The system operates as a single track which starts at the water source and continues until it reaches its intended application so storage decisions determine pump requirements and pipe dimensions determine the necessary pressure levels. The outcome produces a unified design process which replaces separate mathematical computations.
What it does
The platform is organized around two system clusters. The Pumps, Pressure and Pipe Flow cluster guides users through building flow, total dynamic head, friction loss, duty point, power and suction checks. The Wells, Storage and Rainwater cluster connects source yield, pumping, pressure control, stored volume and roof collection. The two systems handle all standard water system planning requirements which most users need to work with.
Key features
Interactive planning tools: Seventeen published calculators and planners including Total Dynamic Head Calculator, Pipe Friction Loss Calculator, Well and Borehole Pump Sizing Planner, Water Storage Tank Sizing Planner, Rainwater Harvesting Yield Calculator and Rainwater Tank Days-of-Supply Simulator.
Field-oriented guides: The collection contains eight comprehensive guides which teach users about pump sizing and pump curve interpretation and low pressure diagnosis and well water system design and pressure tank operation and water storage planning and rainwater harvesting system design.
Technical reference data: Six reference sections with conversions, pipe internal diameters, Hazen-Williams C values, pump formulas and demand planning factors.
Transparent methods: Every tool shows its calculation method, assumptions, limitations and worked examples so users understand what the result means and where it applies.
Dual unit support: SI metric units are primary with US customary units supported throughout. Unit changes convert existing entries automatically.
Who it is for
Water Systems Bench is designed for engineers, technicians, contractors, well drillers, agricultural planners and anyone involved in designing or evaluating water supply systems. The system enables users to create initial plans while performing obvious verification tasks before they access official manufacturer specifications and regional regulatory requirements.
Why it stands out
Water Systems Bench analyzes water systems as complete systems which differ from calculators that examine individual components. The operation of a pump changes whenever you switch pipe sizes because friction levels determine the pump's operating point. The platform makes these connections explicit. Every tool includes a safety review boundary and clearly states that results support preliminary decisions but do not replace professional engineering judgment. The platform is built for global use with consistent methodology across all tools.

Hi everyone! I built Water Systems Bench to make practical water-system planning easier. It connects pump sizing, pipe losses, well and borehole planning, pressure tanks, water storage, and rainwater harvesting in one workflow. The site currently includes 17 interactive tools, 8 guides, and 6 technical references, with more irrigation and treatment resources planned.
