Mark Groenleer
– engineer – Groenleer and Associates - reviewed the Fishbeck study. He
described the process for backwashing. Study was modeled on the rate of
backwashing every 72 hours, however it is his understanding the Wyoming Water
Treatment plant has changed this to every 12-14 days.
Gustaf
VanderVeen – 16420 Quincy – stated the back flush occurs every 12-15.
Grunleer stated the back flushing has remained the same since 1991 even
though they are wrapping up construction. The volume of water they are
backwashing now is less than they were backwashing back in 1991. He
confirmed the validity of the study. There has been no extraordinary
development to change the model of the analysis. There was a countywide
study done by a Hope College professor mentioned in the Fishbeck study
in the 70’s. The study found the same issues and arrived at the same
conclusions. According to the study only one residence was potentially
affected by the water levels.
Docter
asked what the Lake Michigan table was and if it affected this area.
Goenleer stated what the table was and stated it has no affect on the
area. He showed a map regarding lagoons and mounds as it relates to the
Fishbeck study.
Paul
Geerlings – Ottawa County Drain Commissioner - asked when the photo was
taken.
Groenleer stated it was a 2005 aerial photo. A conclusion observed in
the Fishbeck study is precipitation has the greatest influence on the
ground water table. He believes that is the case in this situation.
Visser
stated our building permits process requires a builder to build at least
two (2) feet above the highest known water table. Also, he stated there
is a letter from the MI DEQ which states the Wyoming Water Treatment
Plant is operating within their permit regarding the construction. He
will place the letter on the web site.
Martin
stated the township has little authority regarding issuing building
permits to state regulated entities like the Wyoming Water Treatment
Plant. The township issues some permits regarding the construction, not
all of them. The MDEQ is responsible for ongoing monitoring of the
construction process. The township, by law, cannot sue Wyoming Water
Treatment Plant.
VanIwaarden asked if the neighbors were still pumping.
The
residents stated many of them are still pumping.
Martin
stated the township cannot prevent someone from using their property if
it is a permissible use. The Township would have to pay reasonable
compensation for the land if this were to occur.
VanIwaarden asked Mr. Geerlings what his opinion is regarding the
situation.
Mr.
Geerlings – Ottawa County Drain Commissioner – he gave a history of
precipitation in the area over the last few years. He addressed the
drain cleaning issues and who is responsible for the cleaning. He
described the process of petitioning for a drain district and how the
cost is distributed. He stated the residents within the drainage
district would probably be responsible for approximately half of the
total cost.
Steggerda stated the Township is responsible
for the fees involved in cleaning out the drains.
