CSU has a storm water permit that regulates what measures the university must take and what is to be done to minimize storm water pollution. It is structured with six "Minimum Measures," each of which has multiple goals and requirements. Discharges of processed waste water or contaminated water are not allowed to go to storm drains. In some cases, a specific discharge permit can be obtained to allow discharge of waste water. However, these permits may require monitoring, reporting and treatment to meet the discharge limits. CSU's storm water and surface water discharges are regulated by the Colorado Department of Public Health and Environment (CDPHE).
Colorado State University has a vegetative roof on top of the study lounge of the Microbiology building. Approximately 400 square feet of the study lounge is occupied by a planting tray for various plants. This dramatically reduces the storm water runoff. Twenty percent of the vegetation grown on this roof is part of an experiment, coordinated by Jennifer Bousselot, a PhD Horticulture student, who is researching green roof plant species to determine which western alpine plant species are most useful.
To increase storm water recharge while conserving a significant amount of space, Colorado State University has begun to implement porous paving in construction. Currently, the Industrial Science building’s surrounding areas are built of porous paving. Also, the newly constructed Behavioral Science building incorporates porous paving in its nearby walkways and plazas.
CSU currently has seven detention ponds. These ponds are strategically placed in parking lots and close to buildings to not only limit runoff and flooding but also to remove water pollutants.
On three campuses, CSU uses twelve vegetative swales. These structures filter storm water runoff through vegetation, supplying nutrients to the water.
CSU uses three stone swales on the Main Campus. These swales filter water through stones and a layer of peat ensuring a cleaner storm water returns to the soil.
Biofilters, snouts, vegetative buffers, and filters are all also used in storm water management at CSU. Also, a wetland was constructed in 2003 on campus through the cooperation of students and a landscape architect.
