Local Background on Grosse Pointe Farms
| Issue | The facts | Citation |
|---|---|---|
| Sewer backups in this city | The Lakeside District of Grosse Pointe Farms has had separate storm and sanitary sewers since 1999-2000. The Inland District, farther from the lake, never got that separation. | C&G Newspapers, "Agreement is important first step in upcoming sewer separation project" (Sept. 21, 2022), accessed 2026-10-06 |
| Sewer backups snapshot | In 2025 the city began an Inland District sewer separation project of about $11 million. It adds a 48-inch stormwater force main and a 60-inch gravity sewer that carry rain to Lake St. Clair. The route runs from Chalfonte and Moross, under the Country Club of Detroit grounds, along Kercheval and out to the lake at Tonnacour Place. | C&G Newspapers, "Sewer separation to start this spring in Grosse Pointe Farms" (Apr. 2, 2025), accessed 2026-10-06 |

| On sewer backups | The Inland District still ran a combined sewer in 2011 and had no emergency release to the lake. The Kerby pumps had to handle all flow, however heavy. The Lake District had been separated in the late 1990s. | Patch Grosse Pointe, "Grosse Pointe Farms Residents, Council Ask Same Questions On Flooding" (June 7, 2011), accessed 2026-10-06 |

| Local flooding | After the 2011 floods the council asked its engineers for a plan with a permanent gas-powered backup generator for all eight pumps at the Kerby Road station. The package of recommendations was estimated at $5.24 million. | Patch Grosse Pointe, "Pump Station May Get Permanent Gas-Powered Generator" (Jan. 11, 2012) (retrieved 2026-10-06) |

| The flooding record | Three weeks after the June 2021 flood, heavy rain hit again. The mayor estimated about two dozen Farms homes took water, against about 200 in Grosse Pointe Park. He said a planned $20-25 million sewer project aimed to remove about 35 percent more rain from the system. | WXYZ Detroit, July 2021 - fetched 2026-10-06 |
