Horses

The bacteria in horse manure can cause health problems for people, pets and aquatic life.

What’s in Horse Waste?

Horse waste is organic, but it can contain harmful elements like sediment, phosphorous, nutrients, salts, ammonia, bacteria and viruses. When carried off to local rivers, streams and lakes, these components disrupt the ecosystem and cause harm to life in our local waterways.

Manure Management

Proper management of manure, pastures and paddocks can prevent pollutants from entering local waterways and protect the health of your horse. Follow these best practices when caring for your horse:

  • Collect and remove soiled bedding and manure from stalls, pens and corrals at least once daily.
  • Deposit waste in sturdy, insect-resistant and seepage-free waste containers.
  • Cover manure with tarps during rain events to prevent runoff of pollutants.
  • Arrange for weekly manure pick-up service or compost waste. Consider donating extra compost to community gardens and nurseries.
  • Keep horses away from streams, flood-prone areas and steep hillsides to reduce runoff.
  • Plant vegetation along stream banks to help filter sediments and horse waste before they reach the waterways.
  • Wash horses on a permeable surface or in an area that connected to the sanitary sewer.
