Civil Designer’s foul water (Sewer) module is a comprehensive inflow calculation,

drainage infrastructure design and analysis software program for foul water or
sewerage networks. It calculates the invert levels, slopes and diameters of the culverts,
as well as the design flow, capacity and flow velocity of each culvert.

The program models a network with property connections consisting of both existing
and new culverts, taking into account the hydraulic and geometric relationship between
the different branches in the network. Attenuation is calculated at every manhole, resulting in a solution
that is more cost-effective than simply adding the inflow peaks together.

Unit Flow Classes or Hydrograph total design flow, as well as the total contributing
Inflows population. The design flow is then adjusted
according to the attenuation curve.
We support three inflow calculation methods:
- The Unit Flow method allows you to specify the
number of contributing units of each class at Automatic Culvert Sizing Using
every manhole
Proportional Flow Depth
- The Harmon method uses unit inflow hydrographs
to determine the flow in the network over a period Culvert sizes are automatically selected from the
of time (in most cases multiple inflows can be culvert catalogue, per a specified proportional flow
specified at each node) depth with a maximum user-defined flow depth of

simulates a complex system of branches with surge
tanks and overflows, so you can model the intricate
networks typical of modern cities. Each model can
have multiple sub-networks and outfalls. You can
specify the outfall levels if you want to connect to
existing systems. Alternatively, the program
determines the best possible levels, slopes and
pipe sizes, in accordance with the design
parameters.
