Household Hazardous Wastes

A Threat to You, A Threat to Your Environment

Did you know that once every two and a half minutes someone calls a poison control center to report exposure to a household cleaning substance?Over half of these calls involve the exposure of a child under five years old.2  Most of us have several different kinds of toxic substances in our homes, including cleaning supplies, paint thinner, pesticides, etc.  Not only are these products toxic while inside your home, if not disposed of properly, they can also be toxic to the environment.  Continue reading Household Hazardous Wastes

Construction BMPs: Inlet Protection

Inlet protection is the last line of defense in preventing sediment from entering storm drain inlets and reaching our waterways.  It should never be used as the only Best Management Practice (BMP), and often, if it fails, it is because there is not enough stormwater controls above the inlet to keep sediment on site.  One of the common misconceptions about inlet protection is that it is meant to completely block off the inlet.  Inlet protection should NEVER completely block off an inlet; not only can this be a safety hazard by flooding the roadway, it is ineffective because the sediment-laden water will just pass by to the next inlet.  Instead, inlet protection is meant to slow the water flowing in the curb, shallowly pooling it to allow some of the sediment to drop out.  Inlet protection can be constructed from rock socks, sediment control logs, silt fence, block and rock socks, or other materials.  There are also numerous proprietary products available.  The type of inlet protection you choose should depend on where your inlet is located.

Inlet protection in sump conditions

For inlets located in a sump, that is, at the low point of an area or a curb, it is important that the inlet continue to function during larger runoff events.  For curb inlets, the maximum height of the protective barrier should be lower than the top of the curb opening to allow overflow into the inlet during larger storms.  For area inlets, silt fence or other materials can be used to keep sediment-laden water out of the inlet.  Just remember that if there is no overflow to the inlet, your site will experience some localized flooding.

Silt fence keeps sediment out of area inlets

 

Inlet Protection on Grade

If you inlet is located on a sloped street, instead of blocking off the inlet, you might try using curb socks in the flow line of the gutter uphill from the inlet.  This will slow down the stormwater and give the sediment a chance to drop out before it reaches the inlet without blocking off the inlet.

Curb sock slows the flow of stormwater in curb line before it reaches the inlet

Scottsbluff Receives Stormwater Projects Grant

 

Scottsbluff's first demonstration rain garden

The City of Scottsbluff has been selected by the Nebraska Forest Service as a member community in the Greener Nebraska Towns (GNT) Program.   This program is designed to improvethe long-term sustainability of member communities.  Scottsbluff will be receiving a total of $55,000 in grant funding, $30,000 of which will be allocated to tree planting, and $25,000 of which is to be spent on waterwise landscaping and stormwater management.   We will be implementing demonstration projects that incorporate sustainable landscaping, tree planting, and stormwater best management practices, such as rain gardens, bioswales, and porous pavement.  We will also be working with residents to plant trees and improve irrigation efficiency.  Stay tuned to hear more about everything that we will be undertaking as part of this initiative!

Construction BMPs: Silt Fence

Silt Fence

Silt fence can be a very effective best management practice if it is used correctly. However, it is also one of the most misused and overused BMPs. Using silt fence incorrectly is not only ineffective, it can also be expensive. Here are some tips for using silt fence appropriately:

How to Install a Rain Garden

Note: This post describes the rain garden demonstration project which was installed in Scottsbluff in July 2010 with the help of the UNL Extension Stormwater Team.  The garden is located on the corner of 19th Street and Avenue B.

Step 1 Choosing the Site

Rain gardens are designed to catch runoff from roofs, driveways, streets, sidewalks, or other areas of the lawn.  This was an excellent site for a rain garden because of the downspout that drains into the area.  Minimum work was needed to channel the runoff into the rain garden. Continue reading How to Install a Rain Garden

Additional Tips for Homeowners

  • Review your home for stormwater handling. If your gutter, downspout, driveway or deck directly discharges into a water body, retrofit it by redirecting the runoff onto a grassy area or installing a berm/swale system. Or even install a Rain Barrel.
  • Design your landscaping to limit water use. Install a Rain Garden.
  • If you have an irrigation system, make sure it is in good working order and limit its use to actual watering needs. Install rain sensors into your irrigation system.
  • Consider replacing impervious surfaces like sidewalks, decks and driveways around your home with more pervious materials or methods like mulch, turf block, pervious concrete or clean stone.
  • Retain shrubby vegetation along waterfronts to prevent erosion and help stop heavy rain sheetflow.
  • Never dispose of oils, pesticides or other chemicals onto driveways, roadways or storm drains. The next rain will either carry it into a surface water or help it soak into our drinking water.
  • Reduce the amount of fertilizers, pesticides and herbicides you apply to your lawn and landscaping. What the plants can’t absorb quickly usually results in surface or groundwater pollution.

 

More Ways to Help the Initiative

  • Use environmentally friendly cleaning products — and continue to dispose of them in the proper manner.
  • Educate friends and family on the importance of proper waste disposal.
  • Attend community meetings and citizen panels, and voice your concerns. Continue reading More Ways to Help the Initiative

What You Can Do to Help

Easy tips for keeping our water clean

  • Litter
    Litter disposed of in a storm drain can choke, suffocate and disable aquatic life. Dispose of your litter by throwing it in a trash can or recycling it. In addition, do your part by properly disposing of litter you find in the street or on the sidewalk.
  • Washing your car
    Washing your car in the driveway creates a runoff of soap and other chemicals that ends up in the nearest storm drain. You can either take your car to a self-service car wash, which is designed with special drains for proper disposal, or wash your car on your lawn. The dirt below will act as a filter for the soap.
  • Pet waste
    Pet waste dumped in storm drains goes straight into your rivers and lakes, contaminating the water. Continue reading What You Can Do to Help
