This guide covers the monitoring requirements for green stormwater infrastructure and source control projects. This guide includes monitoring goals, monitoring process, monitoring techniques, data management and reporting.
This guide provides step-by-step instructions for planning and implementing flow monitoring for GROW-funded projects. It covers hydrologic performance, in-sewer flow, and data collection methods. Monitoring is required for all project types including GSI, I&I, DSIR, and SSP. The guide includes templates, equipment recommendations, and data analysis procedures.
The document is intended for ALCOSAN, municipalities, and sewer authorities to use in developing monitoring plans. It does not replace detailed protocols but provides a framework for compliance with GROW program requirements.
Green Stormwater Infrastructure (GSI), Inflow/Infiltration controls (I&I), Direct Stream Inflow Removal (DSIR), and Sewer Separation Projects (SSP).
Minimum 3 months pre-construction and 6 months post-construction; recommended 6 and 12 months respectively.
To assess effectiveness of constructed projects, demonstrate performance standards, confirm modeling estimates, and evaluate system performance.
