Larimer County Water Quality Training

A Guide for Municipal Facilities and Operations

Protecting Our Water, Every Day

Larimer County is committed to protecting natural resources. One of our six Guiding Principles is Being Good Stewards of Public Resources—and that includes the stormwater that leaves our properties and project sites. Every action we take impacts water quality.

Who Manages Stormwater?

The MS4 Water Quality group, part of the Engineering Department, manages the County’s State-issued MS4 Water Quality Permit. This permit guides us in reducing stormwater pollution from County facilities and operations.

Training Overview

This guide will help you:

Understand how stormwater pollution affects the environment
Recognize potential sources of stormwater pollution
Learn best practices for managing stormwater at County facilities and project sites
