Sweeping and Pollution Removal: Sweepers & Tankers Podcast Episode
In this half-hour Zoomcast episode of Bucher Municipal's 'Sweepers & Tankers' Podcast, WorldSweeper.com's Editor, Ranger Kidwell-Ross, provides the latest documented proof showing street sweeping to be nearly seven times more cost-effective than the next best method (catch basin systems) for removing Nitrogen and Phosphorus from the pavement runoff stream.
This presentation is a shorter version of the one shown in our 'Out Front' section, above. It is in more of an interview/response format and does not include the additional info about how to minimize cost of operation and maximize cost-effectiveness value of street sweeping; rather, it concentrates on the value of street sweeping to remove pavement-based Total Phosphorus and Total Nitrogen.

10 Tips for Ensuring a More Environmental and Cost-Effective Street Sweeping Program
Our editor asked Roger Sutherland, arguably the world's top expert on street sweeper testing, to provide five ideas for what a sweeping program might do to increase its effectiveness. Sutherland took it one step further: He offered five ideas that could be immediately implemented into a sweeping program, then added another five that should be strongly considered.
Read the story.
Kidwell-Ross then expanded upon Sutherland's 10 items and they went back and forth from there. The result is a "must read" article for everyone involved in sweeping streets. Whether you are a street sweeping contractor, or a municipal manager or similar, you'll want to take a look at all 10. Then, consider implementing the offered suggestions as soon as possible.
Historical and Current Overview on Characteristics
and Capabilities of Street-Class Power Sweepers
Some years ago our editor developed – and has since kept updated – this 10-page information file about street-class sweepers. The information starts with an overview of the problems with the 1980 National Urban Runoff Program sweeper studies and continues on to discuss the cost-effective value of today's sweepers as a BMP for reducing stormwater pollution.
The cost of removing pollutants via different types of sweepers is compared to that of end-of-the-pipe expense. The PDF-formatted file offers many tips about how and why to sweep, is an excellent reminder about the value of sweeping, offers comparisons of the abilities offered by differing types of sweepers and more.

City of Seattle Doubling its Sweeping Program to Address Stormwater Pollution
Because of Seattle, Washington's location on Puget Sound, and the difficulties it is having meeting mandated pollution reduction levels, the city is planning to increase its street sweeping program significantly in 2016 in an effort to reduce stormwater runoff pollution.
The expansion would increase the number of annual miles swept from 10,000 to 20,000, while the goal for pollutant removal is to increase from the current 100 tons of pollutants taken off the streets currently to 140 tons once the program is fully implemented.

Valdosta Georgia's Clean Sweep Project Receives National Innovation Award
An advanced City of Valdosta Engineering project, titled "A Clean Sweep of Data Collection," has been recognized by the National Association of Development Organizations (NADO) for its creative and efficient approach to street sweeping, which involves installing High Definition, GPS-equipped cameras in the Stormwater Division's sweeper truck, allowing the staff to track, map and record video of the truck's route throughout the city.

Using Sweepers as 'Curbline Plant Removal Machines'
WorldSweeper's editor was asked to provide his professional opinion on the advisability of requiring that a street sweeper be used to remove growing plant material from a curbline. This means plants in the cracks of the curbline, not plants sprouting in dirt that has been lying in the curb for an extended period of time.
The opinion was requested to solve a dispute between a municipal authority – which sought to have the language in its contract – and the contractor tasked with the job.

Implementing a Street Sweeping Best Practice
Through the years, the state of Minnesota has been one of America's leaders in developing best practices for street sweeping. When one looks at a map of the state and sees all the waterways it contains, it's easy to see why that might be the case.
The information collected for the study cover four different topic areas: Best Practices Overview, Types of Sweepers, Reasons for Sweeping, and Sweeping and Roadway Function. In our opinion, if you're in charge of a sweeping program anywhere and want to develop best practices for it, this document is a 'must read.'

New Hampshire Watershed Organization Targets Parking Lot Sweeping to Improve Water Quality
Pennichuck Water Works provides drinking water for residents of the greater Nashua, NH area. Commercial and industrial land comprises about 13% of the watershed and their large impervious areas contribute about 40% of the phosphorus load to the water supply. Parking lot sanding practices also introduce high sediment loads.
As an urbanized watershed, existing developed land uses contribute pollutants such as sediment and phosphorus to the water supply ponds, which have in turn contributed to declining water quality and increased algal blooms. Street sweeping and catch basin cleaning, along with regular maintenance of stormwater practices, has been found to effectively remove phosphorus and sediment from watersheds. Although the watershed communities sweep the roadways and streets, private parking lots and commercial driveways are likely not swept as frequently or thoroughly as they could be, at least not on a widespread basis.
The linked study investigated the pricing differential between having sweeping (and catch basin) companies perform twice-a-year sweeping in an effort to reduce the pollutants, rather than have the Water Works do the tasks in-house. (Spoiler alert: It's less expensive to use contractors.) "Access the PDF report.

An Overview on Porous Pavement Surfaces and Current Sweeping Best Practices
In the United States and around the world clean, unpolluted, water is increasingly being seen as the most precious resource on the planet. It is also being depleted rapidly.
One of the best practices stormwater managers have devised to address stormwater runoff pollution is to design porous, which is also called permeable, pavement. This is pavement that has been designed such that will infiltrate to a subsurface layer, utilizing the ground under the pavement as a recharge area. The article includes an overview on the topic, BMP information on sweeping porous pavement, and a 20-minute audio podcast with an expert in the field.
