LID Treatment Train Tool
With beta testing now complete, version 1.0 of the Low Impact Development Treatment Train Tool (LID TTT) has been officially released!
Access version 1.0 on the Sustainable Technologies Evaluation Program (STEP) website for all the latest updates, including case study examples scheduled for release in early 2018 (access the downloads from the menu bar on the right side of the page.)
Developed by the Lake Simcoe Region, Credit Valley and Toronto and Region Conservation Authorities, the LID TTT is an exciting new open-source tool created to help developers, consultants, municipalities and landowners better understand, plan and implement sustainable stormwater practices.
Using results from the US Environmental Protection Agency's Storm Water Management Model (EPA SWMM5) engine, the tool assesses runoff volume control targets (retention and captured/treated), along with total suspended solids (TSS) and total phosphorus (TP) reductions for both annual and event-based scenarios, throughout the design process. It also provides preliminary water balance analysis (i.e. surface evapotranspiration, surface runoff, infiltration to soil).
The tool is built using the open source EPA SWMM5 model as the engine, to provide a user-friendly interface for novice modelers and can be exported to provide a SWMM5 input file for further model development during detailed design.
Introduction to the Low Impact Development Treatment Train Tool
Date: February 22, 2018
Time: 1pm - 2pm EST
Presenters: Steve Auger, Yuestas David, Sakshi Saini & Alana Vandersluis
The LID Treatment Train Tool can be used right from the conceptual-level planning stage of site development and retrofits for iterative design of LID placement and sizing. It utilizes the Environmental Protection Agency’s SWMM5 modelling engine for its core hydrology computations underneath its clean user-friendly interface targeted at non-modellers.
The tool can run both event based and annual simulations and its output results pertain specifically to design criteria: the water balance, volume control, peak flow, and load reductions for both total phosphorus and total suspended solids. Users can model the pre- or post-development scenarios independently or side-by-side for comparative pre to post analysis. These scenarios drafted at the conceptual-level planning stage can be exported to SWMM5 for further development during detailed design.
