Catch basin cleaning effectiveness study

State and local governments want to learn and share effectiveness of catch basin cleaning programs. Permittees — such as local governments — will coordinate programs on cleaning catch basins to control and prevent pollution in stormwater.

This project will evaluate existing records for catch basin inspection and maintenance. The goal is to identify correlating factors that could be used to predict catch basin maintenance needs and to identify cost efficiencies in program implementation.

Study questions

The survey in this study provides background and study design by asking:

  • What can municipalities learn from existing catch basin cleaning programs?
  • Which alternative inspection schedules and frequencies are most efficient?
  • What is a standard list of data to be collected across programs?

Scope of work

Study findings

This project will develop a SQL database based on survey findings to standardize data collection. The project began in 2016, and is planned to take three years.
