Blood, Trauma, and Biohazard Cleanup in New Berlin, WI

New Berlin is a city in eastern Waukesha County, Wisconsin, forming a neat six-by-six-mile square of about 36.9 square miles in the Milwaukee metropolitan area.

The first settlers, Sidney Evans and P.G. Harrington, arrived in the northeastern part of what is now New Berlin in 1836.

On January 13, 1840, the area — first called the Town of Mentor after splitting from Muskego — was renamed New Berlin by Sidney Evans after his hometown of New Berlin, New York.

Local residents pronounce the city's name with the accent on the first syllable of Berlin (BER-lin), unlike the German capital.

New Berlin stayed rural and agricultural until Milwaukee's suburban migration began in the 1940s — its population grew from 1,293 in 1850 to 5,334 in 1950 and then nearly tripled to 15,788 by 1960.

The Town of New Berlin incorporated as the City of New Berlin in 1959.

The 2020 census counted 40,451 people in New Berlin living in 17,058 households, making it one of Waukesha County's largest cities.

New Berlin straddles the Sub-Continental Divide: about 73% of its land drains west into the Fox River and Mississippi River watershed, while the eastern part drains into the Great Lakes and St. Lawrence River basin.

Large-scale growth followed the New Berlin Industrial Park, begun in 1964; today three business parks covering 1,126 acres anchor an economy whose largest employers include ABB Industrial Systems and ACS Group.

New Berlin maintains 26 parks totaling about 855 acres, including Malone Park near City Hall, a disc golf course at Valley View Park, and the 187-acre New Berlin Hills Golf Course.
