Street Sweeping Museum

Our Technology and Sweeper History from 1950 to Today. Described in detail below.

1950

That seed of greatnesshas never stopped growing for the mission of envirenment health foe all citizens.

1958

Dickson receives the first street sweeoing contract to take over city services. Since then, we have proudly served over 60 major cities, contries, and state agencies.

Dickson Equipment Co. is founded in texas and supplies heavy construction equipment in the cties of Dallas, Houston, and San Antonio for several years.

1980

The state of Arizona grants Dickson the largest contract with the Arizona Department of Transportation for sweeping state highways and freeways.

1982

Dickson beagn using the efficient Regenerative Air Sweeper Sysyrem.

2002

Thw SCAQMD establishes the 1186.1 Fleet Rule to educe air pollution. In anticipation of this mandate, Dickson establishes a new Compressed natural Gas station: California Clean Fuels.

2015

Dickson Lead the industry by adhering to SCAQMD clean air requirements, even ehwn competition economically neglects this responsibility, putting the city at risk.

2020

Dickson continues to lead the industry as they celebrate 70 years of imoeccable service and industry leadership.

FOUNDED ON A HISTORY OF INNOVATION GUIDING THE INDUSTRY INTO THE 21ST CENTURY

Dickson, a leader and one of the longest family owned street sweeping companies has experienced first-hand the evolution of street sweeping technology for over 65 years. Below is their pictorial history of their Street Sweepers.

TECHNOLOGY HISTORY

The goal of simple debris removal changed the 1970’s, when policymakers begun to reflect concern for water quality. In the United States, the Stormwater-runoff Report of 1998 rang an alarm indicating that older street sweepers were not effective in removing large particles of road debris. Small particles of debris remained behind in large quantities. The remaining debris was not seen as an aesthetic issue because rain would wash them away. Today, small particles are known to carry a substantial portion of the stormwater pollutant load. By removing these particles and debris, Street sweeping can be an effective measure in reducing pollutants in stormwater-runoff. The Environmental Protection Agency (EPA) considers street sweeping a Best Management Practice in protecting our environment, air and water quality. Regenerative municipal air street sweepers are capable of collecting small particles of debris and outperform the mechanical broom type street sweeper. The less effective mechanical broom sweepers account for the greater majority of all street sweepers used in the United States today. A regenerative air street sweeper uses forced air to create a swirling effect inside a contained sweeping head and then uses the negative pressure on the suction side to place the road debris inside a hopper. Debris is removed from the air by centrifugal separation and reused, keeping particulate matter inside the hopper. Many regenerative air sweepers are AQMD certified and can pick up particles as small as 10 micrometers or less (PM-10), a leading cause of stormwater pollution.
