BROOKLANE ACRES AREA SEWER LINING PROJECT

The Brooklane Acres Area Sewer Lining Project is underway so you will be seeing "Mr. Rehab" trucks out and about in your neighborhood.  You may be asking yourself "what is a sewer lining project?" A sewer lining project rehabilitates old existing sanitary sewer lines by pulling a liner (which looks like a long sock) through the old pipe and then, by introducing hot water, the liner expands and hardens to create a new pipe within the old pipe. This process is used in mature neighborhoods that have old terracotta sewer lines. The sanitary sewer lines are located under roads, driveways, fences, sheds, swimming pools, and other obstacles. Under these circumstances the lining option is a winner - the Authority will have "new" sewers in the area and the residents will gain more reliable sewer service while generally not having their property disturbed. Manholes in the project will also be lined with a coating, which is sprayed on the interior of the manhole to provide protection against deterioration and to stop groundwater infiltration into the manhohele.

The contractor started the project in early April and has nine months to complete the work. The contractor will spend the first three or four weeks of the project getting the sewer lines ready for lining by cleaning and televising them. If it is determined during the televising portion of the project that there is a defect in the sanitary sewer line, an excavation will be necessary to repair the sewer so that it can be lined properly. When the lining/manhole rehabilitation work is to take place in your part of the neighborhood you will be notified by a mailer in your door with more information about the project. Please be advised that you may notice a slight temporary odor during the lining work.

There will be an Authority inspector from Gibson-Thomas Engineering on the job site who will also be the contact person for the residents involved in the project. Please direct your questions and/or comments to the Authority inspector not the contractor doing the work.

The Authority would like to thank you in advance for your patience and cooperation during this project. If you would like to view a map showing the project limits or have any questions about the project please feel free to contact the Authority.

Wipes Clog Pipes!

 

Save yourself a mess and money - Watch VIDEO1 or VIDEO2 (Disclaimer - these videos may not be appropriate for the squeamish)

 

The increased use of “convenience” wipes is creating problems for home and business owners and increasing headaches for the operators of the local sewage system, as well as sewage systems throughout the country.

“Convenience” wipes are items such as baby wipes, disinfectant wipes, and even many of the cleansing cloths advertised as “flushable”. The problem is that although, yes, you may be able to flush these products down the toilet, their cloth-like material does not break down in the sewer system like toilet paper. A recent Consumer Reports test performed with a lab stirrer showed that toilet paper breaks down quite readily in a matter of seconds whereas a supposedly “flushable” wipe did not even begin to fray after half an hour (see the video above). You can try this experiment yourself – even get your kids involved (it would make a wonderful science fair project).

Each home or business has a sewer line which connects the house or building to the sanitary sewer system. This sewer line is generally called a “lateral” and it is the property owner’s responsibility to keep the lateral in good working order. Sewer line clogs caused by “flushable” wipes, grease, paper towels, rags and the like have created messes in homes and can be expensive to unclog. If these items move further down the sanitary sewer system, they can lead to clogs in main sewer lines and in the pumps at sewage treatment facilities. Such clogs greatly increase maintenance costs and can also cause sewer backups and overflows, something nobody wants to see (or smell).

Remember that what you flush or pour down the drain may clog your pipes – leading to expensive remedies – and may also:

  • Create dangers to workers
  • Cause problems in the sewer system
  • Adversely impact the treatment facility
  • Cause harm to the environment
  • Ultimately jeopardize the welfare of the public

The Authority’s regulations prohibit the discharge of sewer clogging materials into the sewer system. And the Authority will take enforcement action against any residential, commercial, or industrial facility that it determines to have caused a sewer backup due to flushing such products. We aren’t saying don’t use them, just throw them in the garbage when you’re done – the toilet is not a trashcan!

So please help to keep the flowing going…keep the “wipes” out of pipes! Thank you.

 

 

 

 

 

Smoke and Dye Testing

The MAWC uses smoke and dye testing, television camera work, and manhole inspections to pinpoint defects in sewer lines and house laterals that may cause excess infiltration and inflow (I&I) to enter the sewer system. In the sewage business, I&I (infiltration and inflow) is defined as unwanted storm water entering the sewer system through cracks in sewer lines (infiltration) or directly through manhole lids, downspouts, driveway drains, or other such conduits (inflow). I&I creates problems by overburdening both the collection system (sewer lines) and treatment facilities during times of heavy rainfall. The elimination of major sources of I&I can alleviate sewer line overflows and hydraulic overloading of the treatment plants. 

 

 

 

Do Not Flush These Items – Place in the Trash or Recycle Appropriately

  • Convenience Wipes – as noted above, a common cause of clogs
  • Disposable Products – Diapers, disposable mop/sweeper heads, feminine hygiene products
  • Paper towels, dish rags, scouring pads
  • Food products larger than ½ inch in any dimension
  • Kitchen Grease (another major clogger)
  • Flammable Liquids – Gasoline, paint thinner, diesel fuel, lighter fluid, solvents
  • Motor oil, transmission fluid, anti-freeze
  • Pharmaceutical Products – The lingering effects of the chemicals in these products can contaminate streams and other waterways
  • Low pH Products – Battery acid, pool chemicals, muriatic acid

 

  • High pH Products - Sodium hydroxide (aka lye/caustic soda, ammonia)
