DRINKING WATER SOURCE

In November of 2017, the Genesee County Drain Commissioner put into service a new state of the art water treatment plant which is fed by the Karegnondi Water System.  At that time, Grand Blanc Townships water source changed from the Great Lake Water Authority (formerly Detroit Water and Sewer Department) to the Genesee County/Karegnondi system. 

The water comes from the same source as GLWA, Lake Huron, and in fact, the inlets for the pumping stations are just a few miles away from each other. The Treatment plants use the same methodology, mircofiltration and chlorination with fluoride, to treat the water and make sure it is safe. 

The links below will give you more information about the current water treatment techniques and contact information for the two organizations.

These include bacteriological testing, water quality parameter testing, disinfections bi-products, lead and copper, UCMR4 testing, arsenic (emergency wells only), and many other non-regulated samples.
