A key input to a water distribution system model is the demand assigned to locations in the system. For most of the history of modeling and most models today, these demands are based on a known volumetric flow rate. Some, however, would argue that all water leaves the system through some kind of pressurized orifice and demands should be modeled as pressure-dependent. Software today, like OpenFlows WaterGEMS, has the ability to model demands as volume-based or pressure-dependent.

To maintain adequate self-cleaning velocity, you need smaller pipes, which means you need to pump. By varying the diameter in model runs, you can look at the effect of trading off velocity vs. head loss.

A key input to any model with pumps is some form of pump head curve showing flow vs. pump head. Given the curve, the model can tell the user the exact point on the pump curve at which the pump will operate.

One of the most common questions we get from our WaterGEMS/WaterCAD users is how to model the connection between a proposed land development and the water distribution system supplying it.

SewerGEMS tiene la capacidad de dimensionar conductos, establecer elevaciones de plantilla (invert elevations), determinar el tamaño de las captaciones, así como generar un diseño sanitario/pluvial automáticamente, al mismo tiempo que cumple con las restricciones especificadas por el usuario en el diseño automatizado.

Simulating low pressure in your hydraulic model can identify/confirm the cause of the problem and point you to the right solution.

SewerGEMS é capaz de dimensionar automaticamente tubos, bueiros e estruturas hidráulicas além de determinar cotas de fundo. Além de ser capaz de dimensionsionar atendendo diversas restrições definidas pelos usuários durante o dimensionamento automatizado, como faixas permitidas de inclinação, velocidade recobrimento e tensão trativa.
