What should you do to prevent the discharge of untreated waste from a type one or type 2 MSD?
Types I and II MSDs with Y valves that would direct the waste overboard must be secured so that the valve cannot be opened. This can be done by placing a lock or non-reusable seal on the Y valve or by taking the handle off the Y valve. Type III MSDs provide no treatment and are either holding tanks or portable toilets.
What type of waste products may be discharged into the US waters?
Federal law prohibits the release of waste matter of any kind into U.S. waters. This includes trash, garbage, oil and other liquid pollutants. In addition, these rules apply to all boat types and depend on how far your boat is from shore. Note: It’s ALWAYS illegal to dump plastic into the water.
How far offshore do you need to be to dump waste?
The United States has robust laws regulating the disposal from boats of garbage and plastics—it is illegal to put any garbage into the water from a vessel that is on a lake, river, stream, or any coastal waters up to 3 miles offshore.
Where is treated sewage discharged?
The smaller coastal treatment plants at Warriewood, Cronulla, Port Kembla, Shellharbour and Bellambi discharge treated effluent closer to the shore. Less than 1% of Sydney’s wastewater is discharged untreated to the ocean at Vaucluse, Diamond Bay and Diamond Bay South.
Can untreated human waste be dumped in inland waters?
One cannot dump raw sewage, into the water, anywhere within three nautical miles of shore. Always check with local authorities to verify what can and cannot be dumped into the waters one plan to boat on. Finally, remember that untreated human waste may never be dumped in any inland waters.
What is untreated sewage treatment?
Untreated sewage (or raw sewage) is all sewage that has not passed through a treatment system. This is sewage that is discharged directly from a toilet into a waterway (in areas where discharge is permitted) or contained in an on-board holding tank.
How is sewage treated?
Primary Treatment As sewage enters a plant for treatment, it flows through a screen, which removes large floating objects such as rags and sticks that might clog pipes or damage equipment. After sewage has been screened, it passes into a grit chamber, where cinders, sand, and small stones settle to the bottom.
