Residents of the Las Vegas Valley play an important role in improving and maintaining stormwater quality in our community. This page and the links below provide valuable information about how residents can help manage stormwater and reduce nonpoint source pollution.
Stormwater hits home! Pet waste and yard debris, household chemicals, household cleaners, paint and vehicle fluids are examples of materials that can cause stormwater pollution if not properly stored or cleaned up when spilled outdoors.

Initiated by the Conservation District of Southern Nevada and led by the Stormwater Quality Management Committee, the Stormwater Inlet Marking Program originally placed 8,000 "DON'T POLLUTE - DRAINS TO LAKE MEAD, NO CONTAMINE! SE VA AL LAGO MEAD" bi-lingual plastic plaques that adhered to the sidewalk above stormwater inlets and drainages in the Las Vegas Valley. The purpose of the Stormwater Inlet Marking Program is to revive a multi-agency effort to raise awareness of the importance of stormwater quality protection.
The goal of the inlet marking program is to remind people that any toxic materials dumped into the storm drains will be channeled to Lake Mead, Southern Nevada's primary source of drinking water.
The effort is necessary to prevent pollution from petroleum products, paint, pesticides, fertilizers, and litter. Having this message at the stormwater inlets helps the public make the connection between the water that flows into the basins and the water that will eventually be pumped from Lake Mead to their faucet.
The program continues today with all new developments required to follow the Regional Transportation Commission of Southern Nevada's standard drawing No. 421. The standard requires the message "DON'T POLLUTE - DRAINS TO LAKE MEAD" be stamped into curbs above stormwater inlets.
In addition, through the use of grant money, Clark County continues to purchase plastic plaques to place on unmarked stormwater inlets.
