TIMELINE:

1973: Sewer line installed

1978: First sinkhole

2004: Second sinkhole, occurred west of Hayes in Sterling Heights. Cost to repair: +/- $50 million

2009: Sewer line purchased by Macomb Interceptor Drainage District from Detroit Water & Sewerage Dept.

Dec. 24, 2016: Sinkhole developed; 23 homes evacuated. 13 Million gallons of sewage are discharged into the Clinton River.

Jan. 1, 2017: Commissioner Miller’s first day in office.

Jan. 2: First by-pass pump & pipes installed. This allows roughly the “dry weather” flow to be diverted around the collapsed interceptor. Booms and disinfectant is staged at 6 locations along the Clinton River (or county drains that feed into the river) in case another sewage discharge is necessary.

Jan. 5: County declares state of emergency

Jan. 6: State declares state of emergency

Jan. 8: Governor visits site

Jan. 8: (evening): 20 homes are able to be inhabited with creation of temporary road

Jan. 10: Environmental testing due to concerns about odor in homes. All tests come back with results showing no presence of dangerous gas, EXCEPTION: one home on Hayes had a bad seal on a toilet in the house. That toilet was repaired and the problem dissipated.

Jan. 15: Congressional delegation visit to sinkhole

Jan 17: Sinkhole mentioned at Gov. Snyder’s State of the State address

Jan. 26: The collapsed MIDD interceptor is completely filled with sediment. Flow through the interceptor is reduced to “seepage.” Estimates are that as little as a quarter inch of rain will cause sewage to need to be discharged into the Clinton River.

Jan. 27 (morning): Agreement is reached to divert some flow to Mount Clemens waste water plant. MDEQ, Clinton and Harrison townships all have to agree and give agreement.

Jan. 27 (afternoon): Meeting at Public Works of 10 of the 11 elected leaders of the MIDD community at Public Works. Press conference follows.

 

Estimates:

February 4th week: Hayes north of 15 mile closed for duration of interceptor replacement. Use 15 mile to Moravian as a detour.

March 1st week: Third (and final) by-pass & pipes turned on. This will allow roughly the “normal weather and use” flow to be diverted around the collapsed interceptor.

March 2nd week: Interceptor replacement starts
