Educational Articles The most common Kitchen BMPs are listed from this link. The best way to stop FOG from building up in sewer lines is to prevent it from entering your drains, by using “Kitchen Best Management Practices.” check here for brochure The Roanoke Incident, Garden Hoses and Backflow In October, 1979, an incident occurred in Roanoke that unfortunately made that city the Virginia “poster child” of the potential hazards of backflow. Thirty years later, it is a situation that is well-known among water system administrators and operators throughout the state, and it is still discussed at conferences that involve backflow. more... Understanding Backflow and Cross-Connections It is natural for us to assume that our tap water flows in only one direction as it makes its journey from the water treatment plant to our home, institution, or business. The water is certainly not always flowing by gravity, but pumps that are positioned at critical locations maintain water pressure, and keep the water moving in the same direction. more... What Is That Pink Stuff in My Bathroom? Each year, a few customers call to ask us about pink stains or residues that occasionally develop in moist areas in their homes. They generally observe this in toilet bowls, around sink and tub drains, on shower curtains or other shower surfaces, and even in pet water dishes. The customer naturally wants to know if there is something wrong with his/her water. more...... What Is That Black Slimy Stuff in My Bathroom/Kitchen/Laundry Room? Welcome to the fascinating, but often annoying, world of micro-organisms! If you are experiencing dark gray/black stains or slippery residues in the shower, in a toilet, at a tap, or in the washing machine, you do not have a water quality problem, and you need not fear a health issue. These residues indicate the presence of naturally-occurring mold (fungi), possibly in combination with bacteria, which are commonly seen in our area, and are generally harmless. Just as is discussed for the bacteria that cause the pink stains, mold spores that result in the slimy black residues are present in leaves, soil and mulch, especially when moist. They enter your house through open windows and doors, on your pet, and on your own hair and clothing; you truly will be unable to keep them entirely out of your home. As with the Serratia bacteria, the spores that find a moist environment, especially where it is also dark and air flow is limited, will be more likely to survive and thrive. In addition to the locations listed above, the drain tube and bucket of a dehumidifier, and the water dispenser spout of a refrigerator, are other typical places the black film may be found. Grease and Sewers – A Recipe for Problems The Albemarle County Service Authority maintains over 250 miles of sewer lines and related facilities as we collect the wastewater from homes, institutions, and businesses, and transport that wastewater to various treatment plants. Just like the blood vessels of your body, the sewer lines work best when they are clear of any debris. more... |
