Oakland Township - Twin Lakes Drinking Water Quality
We are pleased to report that your drinking water is safe and meets Federal and State requirements. For more information about Oakland Township Water Quality view the Twin Lakes Annual Water Quality Report. This report is compiled from data received from bacteriological and other water quality sampling collected by WRC staff. Many contaminants are analyzed but are not listed in the report if not detected.
Additional information about water usage and system maintenance can be found in our Customer Materials library.

The source is groundwater found in glacial materials. Two wells provide the pumping capacity for this well water supplied system. Ortho-polyphosphate is added at the wellhouse for corrosion control and chlorine is added as a disinfectant.
There is no lead or copper in the source water and no known lead service lines in the water system. View the lead and copper results for the Twin Lakes water system.
Lead and copper contamination comes from leaching of plumbing materials. Corrosion control chemicals (phosphate) are added to the water at the treatment plant to minimize leaching into drinking water. Things you can do to minimize consuming water containing leached plumbing material are as follows:
- Use cold water for drinking and cooking
- Flush your faucet if not used for more than 6 hours
- Clean out your faucet aerators on a regular basis
- Consider replacing your faucet if older than 2014. Faucets newer than 2014 are considered lead free (less than 0.25% lead allowed).
The State's Lead and Copper Rule requires that water operators create a plumbing material inventory. If you know what your in-home plumbing material is, please call 248-452-9158 or email wrcwater@oaklandcountymi.gov.
More information about lead can be found at michigan.gov/mileadsafe.
Your water pressure is dependent on your elevation.

Ground water supplied (well) drinking water systems may experience yellow, orange, or brown water during high demand times (such as hot and dry weather). The discoloration of the drinking water is typically caused by iron particles. Iron in the drinking water is not a primary health concern according to the Safe Drinking Water Act. Iron in the water does cause aesthetic/nuisance problems in the water system. Customers could contact an in-home treatment company for appropriate water treatment equipment.
Outdoor water use, primarily the sprinkling of lawns, significantly impacts water pressure and the sizing of water system infrastructure when the sprinkling is scheduled during peak demand times.
To improve your water pressure and decrease costs required for system expansion: water the lawn or set your automatic sprinklers to operate between the hours of 10 p.m. to 4 a.m. or 9 a.m. to 4 p.m.
Michigan State University recommends light, frequent irrigation applied in the early afternoon.
- There are no known lead service lines in the Twin Lakes water supply system (WSSN 6696).
- WRC has operated the Twin Lakes water system since its beginning in 1997 and the first water tap to the Twin Lakes water system was made in 1998.
- Residential water service lines are typically one inch or smaller. Oakland County standards required copper as the service line material since 1957 for water service lines with a diameter of two inches or less.
- High density polyethylene (HDPE) was allowed as a service line material starting in 2007.
- Lead was banned as a water service line material in Michigan in 1988.
