Designing for the treatment train: Smarter SuDS workflows
with Flow v18.0 & SmartTools v10.0

Drainage design is no longer just about moving water away from a site. Today’s designs need to demonstrate treatment, resilience, compliance, and buildability - all while helping teams work faster and with greater confidence.
This CPD certified webinar on Designing for the Treatment Train, features guest speaker Martin Young, a prominent industry voice, who shares practical insight into treatment train thinking and how it supports better SuDS design outcomes.
We also showcase what’s coming in Causeway Flow v18.0 and SmartTools v10.0, presented by Dr. Netsanet Mebrate, including improvements that help teams design, review, and evidence their drainage solutions more effectively.
Understand treatment train thinking and why it matters for modern, approval-ready drainage design.
Strengthen your approval submissions
Learn what evidence approving authorities expect and how to demonstrate a compliant SuDS strategy.
Design faster with Flow v18.0 and SmartTools v10.0
See how the latest tools help you iterate, evidence, and output better designs with less rework.
Latest roadmap showcase
You’ll see how the latest roadmap direction supports:
-
Clearer water quality assessment using a CIRIA C753 Simple Index approach.
-
Faster storage sizing with improved storage auto-design.
-
Better evidence of infiltration performance.
-
Safer and faster design iteration with undo/redo history.
-
Stronger design control through link type slope constraints.
-
Closer SmartTools and Flow alignment, including enhanced CAD-based editing and output control.
