Project Flowsheet Designer
Start with the guided project intake or build directly on the canvas, then inspect sizing and effluent at every stage.

Describe the source, scale, influent, and constraints to compare defensible treatment concepts, or start from a template or blank train.
Influent
Import from Excel
Reads the six influent fields in a VerWater export. For other column layouts, use Wastewater Projects → Import customer table. Maximum 2 MiB.

Enter laboratory measurements and explicitly state their basis. A typed value starts as Assumed until you mark it Measured; the app never upgrades provenance silently.

Hydraulic profile — site levels and energy balance
Build a required water-level envelope from the downstream boundary through every main-path unit. Supply total reach losses or calculate full-pipe connections with explicit remaining unit/control losses for each flow case. Existing individual weir/channel losses are not automatically treated as total plant losses.
Connect a valid main water path before creating or reviewing hydraulic cases.
Required energy envelope for the drawn main water path at each specified flow case. Supplied total losses must include units, pipes, fittings, controls and operating condition. Velocity head is alpha*V²/(2g). Explicitly attached reservoir pump studies supply their reach head and complete losses. This is not a backwater, weir-submergence, surge, whole-network pump/control or recycle/sludge-network solver. Freeboard applies only at the listed open-water checkpoints; intermediate high points and controls require separate checks. Extra inlet energy needs an explicit dissipation/control design.
