Biohazard Cleanup Near West Sweeny Sweeny, TX

Sweeny is a city in west-central Brazoria County - the westernmost incorporated town in the county - at the junction of Farm Roads 1459 and 524, about 20 miles southwest of Angleton.

The land under Sweeny was granted on July 24, 1824, to Dr. Imla Keep, a physician and one of Stephen F. Austin's "Old Three Hundred" colonists.

The town is named for the family of John Sweeny, who arrived from Tennessee in 1833 and purchased the Imla Keep league in 1835.

When the St. Louis, Brownsville and Mexico Railway reached the area in 1905, the community was briefly known as Adamston.

Sweeny's post office was first established in 1895 and was re-established under the Sweeny name in 1909.

Developer Burton D. Hurd platted the townsite in 1911 and promoted ten-acre garden farms with the slogan "Soil Richer Than the Valley of the River Nile."

Sweeny had an independent school system by 1912, and the discovery of the Old Ocean oilfield in 1934, followed by a gasoline plant in 1938, transformed the local economy.

Sweeny incorporated in 1945 and today governs itself under a home rule charter adopted in 1999 with a council-manager system; the city's motto is "A City With Pride."

Sweeny Community Hospital, run by a hospital district created by the Texas Legislature in 1963, has served Sweeny and western Brazoria County since 1965.

Sweeny's population has stayed remarkably steady for decades - 3,624 in 2000, 3,684 in 2010, and 3,626 in the 2020 census.
