While Bentley no longer actively sells new subscriptions for V8i (as of 2025, support is sunsetting), the feature set remains a powerful legacy tool. For engineers who need to maintain, calibrate, or expand an existing model library, SewerCAD V8i is irreplaceable.
By optimizing pipe slopes and sizes, the software reduces material and construction costs 1.2.2.
: One of the most touted features of V8i was the ability to run SewerCAD "exclusively" within AutoCAD , MicroStation , or as a Standalone application using a single license. sewercad v8i exclusive
, SewerCAD V8i (starting with SELECTseries 4) allows for 3D modeling of networks driven by hydraulic constraints like slope, velocity, and pipe cover. Bentley Systems Technical Tools for Engineers LoadBuilder & ModelBuilder : These tools automate the most tedious parts of modeling. ModelBuilder imports external data from spreadsheets or GIS, while LoadBuilder

Master Civil Infrastructure: The Definitive Guide to Bentley SewerCAD V8i
One of the most powerful aspects of SewerCAD V8i is its constraint-based automated design engine. Instead of manually adjusting pipe diameters and invert elevations through trial-and-error, engineers can input design criteria and let the software optimize the network. Constraint-Based Pipe Sizing : One of the most touted features of
Allows the modeling of flow splits, weirs, and bypasses to accurately simulate complex combined sewer overflows (CSOs) or diversion chambers. Data Integration and Interoperability
: V8i introduced refined "Scenario Management" which allows for "Exclusive" alternatives—enabling engineers to compare different pipe sizes or pump configurations within the same model file without overwriting data.
SewerCAD V8i stands out by offering two distinct analysis methods within a single platform:
