SEPTIC SYSTEM STUDY

Did you know that septic systems are considered the sleeping giant of potential pollution of Platte Lake?

The Platte Lake Improvement Association has completed its most comprehensive analysis of the septic systems that surround Platte Lake. There could be as many as 1 out of 6 systems fall into a high-risk category. A study done in Mid-Michigan found that 20% of people who have septic systems did not even know they had one!

Read about our analysis here to learn more about how you can keep Platte Lake safe by knowing your septic system.
