The First WWTP in a 400+ Expansion: Planning with Confidence at Scale

How Sabesp, Latin America’s largest water utility, integrated Generative Engineering with TDG into their workflows to help make stronger, faster planning decisions as they prepare to meet Brazil’s most ambitious sanitation deadlines.

Background

Problem

SABESP, Brazil’s largest water and sewage utility, committed to reaching 90% sewage collection and treatment coverage across São Paulo state by 2029, four years ahead of the country’s 2033 federal sanitation deadline. 

Closing the gap from 67% to 90% coverage meant planning and delivering more than 400 wastewater treatment plants, under discharge standards that continue to tighten.
The utility needed a faster, more rigorous way to evaluate design alternatives without the months-long, consultant-led studies that couldn't scale across a 400+ plant program on a fixed deadline.

Solution

Utility uses TDG

SABESP used the Transcend Design Generator (TDG) Wastewater Treatment module to evaluate design alternatives for the first plant in the program, Limoeiro WWTP. They brought the workflow in-house, generating and comparing options led by an internal process engineer.

Results

Key Wins

18 viable alternatives evaluated
6× more options evaluated vs. traditional approach
8× faster planning timeline (2 months to 1 week, end-to-end)

The platform helped us define the layout and size of our tanks and structures so we could move to contracting as quickly as possible. It let us launch projects for hiring works in a much more agile way.
