St Simons Island Sanitary Sewer Smoke Testing Project Beginning on May 1, 2019

Written by jsellers on . Posted in For Your Information, General News.

Want to know more about the smoke testing methodology that will be used to help set maintenance priorities for our sanitary sewer collection system on St. Simons Island?

On Monday, April 29, 2019, members of JWSC staff will be present in room 108 of the St. Simons Island Casino at 550 Beachview Drive from 6:00 to 8:00 PM to discuss the project. A short presentation will be repeated every 30 minutes with time allotted for discussion. Please drop in when you can to hear more about this process that will use a mist that is safe for your health and for the environment.

The map below will be on display in large format and copies of the schedule will be made available so that you may be best prepared to see the crew members from McKim & Creed Engineering Consultants as they perform this essential work:

 

Doorknob notices will be distributed a few days in advance to commencement of testing in an area.

One significant product of this study is the identification of defects in our sewer mains and private service connections that may be contributing to an increase in wastewater processing costs at the treatment plant due to rainwater pouring into manholes and clean out connections (known as inflow) and groundwater seeping into cracks in pipes (known as infiltration).

Smoke may rise up in the street, in your yard or even in your house but our consultant will have their staff actively alerting you to their presence in your area while the work is being performed. The visual below may help with your understand of what paths this mist or smoke may take while venting out to the atmosphere:

To aid in your understanding, our staff has also produced the following videos on the subject:

Please don’t be alarmed if you spot a crew with DMD Consultants on their vehicles or uniforms exercising hydrants near you this week. In an effort to be proactive and determine maintenance priorities for our vital fire suppression distribution network, DMD will be performing manufacturer recommended inspections on 160 hydrants this week.

Update Regarding Whitlock Street Emergency Road Closure – April 22, 2019

Written by jsellers on . Posted in Road Closure.

On the morning of Thursday, April 18, 2019, the JWSC was alerted to a sinkhole that had developed in the eastern shoulder of Whitlock Street in Brunswick. For the safety of local residents, commuters and our staff, the road was fully closed until an update could be provided as to the cause and repair method for this sewer main collapse. The original road closure information is provided here: https://www.goldenisleslepc.org/emergency-road-closure-4100-block-of-whitlock-street-in-brunswick-thursday-april-18-2019/

As of Saturday, April 20, our staff has determined that the repair will be extensive enough to justify keeping the 4100 block of Whitlock Street closed in the vicinity of the worksite until the repair process can be completed. Homeowner access is being maintained but all other traffic should be prepared to take another route.

The following details may be helpful to understand the cause of the sinkhole, the condition of the gravity sewer main and the repair process:

  • The gravity main buried around 20 feet along Whitlock is made up of reinforced concrete pipe that has deteriorated over decades of use and become brittle in some sections, exposing the re-bar.
  • A 540 foot section of this pipe, manhole-to-manhole, is being bypassed to allow services to continue uninterrupted.
  • Later this week, CIPP (Cured In Place Pipe) technology materials will arrive that will allow the JWSC to repair the deteriorated pipe with a liner that will cure and harden to the point where a suitable long-term solution can be obtained short of excavating the street. A helpful video describing this process can be seen here.
  • Until this lining has been installed, Whitlock will continue to remain closed to thru-traffic.
  • Optimistically, the repairs could be completed by the end of this week.
