Low Impact Development Treatment Train Tool Workshop

October 24, 2018 9:00 am to 3:30 pm
CCIW Office, 867 Lakeshore Rd, Burlington
Instructors: Sakshi Saini and Alana Vandersluis

Produced through Canada’s Climate Change Adaptation Platform, with support from Natural Resources Canada.

Course description

The Low Impact Development Treatment Train Tool (LID TTT) has been developed by Lake Simcoe Region Conservation Authority (LSRCA), Credit Valley Conservation (CVC) and Toronto and Region Conservation Authority (TRCA) as a tool to help developers, consultants, municipalities and landowners understand and implement more sustainable stormwater management planning and design practices in their watersheds. The purpose of the tool is to analyze annual and event based runoff volumes and pollutant load removal by the use of Best Management Practices (BMPs) and Low Impact Development (LID) techniques. The LID TTT provides preliminary water budget analysis (i.e. surface ET, surface runoff, infiltration to soil) and pollutant load removal estimates for pre- and post-development scenarios. The tool is built upon the open source EPA SWMM5 model providing a user-friendly interface for novice modelers and cross-compatibility with SWMM5 for further model development.

The intent of this workshop is to provide an overview of Version 1.2.1 of the tool which is available for free download on the STEP website (https://sustainabletechnologies.ca/low-impact-development-treatment-train-tool/).

A detailed walk through of the model capabilities, case study examples, along with a Q & A and experimentation period will all be a component of the full day workshop.

Development team representatives from the GTA CAs will be co-delivering this session. Participants are requested to download the LID TTT prior to the workshop and to bring a fully charged laptop.

Who should attend?

This workshop is intended for practitioners preparing SWM Design packages to meet criteria and objectives for approval.

Learning Objectives:

1. Appreciate model criteria and rationale that supports the selection of preferred open-source and/or commercial license LID modelling tool(s) which effectively demonstrate design targets have been met.
2. Understand the capabilities of the LID Treatment Train Tool, utilizing EPA-SWMM as the engine, to estimate pre and post water balance, runoff volume control, peak flows, total phosphorus and total suspended solid loading and removals through the treatment train represented through walk through instruction and case study examples.
3. Recognize how an adapted LID TTT may be used to enhance discussions during preliminary planning efforts, and to be re-applied for final design and assessment (for approval, subject to pre-consultation input from relevant agencies).

Additional Information:

Lunch will be provided.
