Construction Entrance Fail

This is a 30 + acre site with one access point, this one. If this was my project, I would have specified a tire wash with an asphalt exit to the street. The tire wash would have been long enough for two tire rotations, have high pressure, low volume nozzles located such that all tire surfaces were sprayed. This system would also have an on-board, treatment polymer injection system to keep the tire wash water relatively clean. I would have specified that the water be tested for turbidity daily, measured at 50 NTUs or less. Since the water is classified as “process water”, I would have required it to be tested for metals and other contaminants, then hauled to an appropriate disposal facility.

Truck Being Loaded on Asphalt Keeps Tires Clean

If I’ve said it once, I must have said it 3 or 4 times: “Keep your tires clean!”. Who wants to use a tire wash and have to get rid of a whole lot of dirty water (process water) that can’t go down the storm drain? Save yourself some hassle and money. Give your employees a raise with the money you save.

The Soaker Tire wash

These are great as long as the tires are not too muddy, the mud is not too sticky and the vehicle load is not too high. Most of the water is directed to the sidewalls and misses much of the mud hiding in the treads. These work great as the final , clean rinse cycle in conjunction with a tire bath best management practice. Chemical flocculants can be added to the water to remove much of the sediment load.

Description from the website: http://www.thesoaker.com/

“The Soaker” is a portable, self-contained and environmentally friendly wheel washing system. The system does not require city power or water connected to it which makes it highly portable.

“The Soaker” can be installed on job sites, dump sites and material pits to help keep the surrounding streets free of mud and dirt.

Its aluminum and stainless steel construction makes “The Soaker” environmentally friendly.

It features a high capacity main tank of 4000 gallons and a reserve tank of 2000 gallons. Its adjustable spray heads provide a low pressure/high volume water stream of up to 1000gpm. Motion sensors detect the vehicles on approach and turn on the pumps so the water spray is at full power by the time the vehicles go through the wheel wash.

“The Soaker” is manufactured to provide solutions to problems such as portability, road pollution, costly cleaning processes, fines and violations for depositing debris onto public highways, etc…

“The Soaker” can be rented on a monthly basis or purchased. A lease purchase option is also available. For more information about “The Soaker” wheel washing system, please call us at: (818) 952-6752 or email at: soakerinfo@thesoaker.com

Managing Construction Projects to Prevent Sediment Trackout

I originally submitted this abstract for the 2019 IECA Denver conference . It was not accepted as a presentation but as an article in the October 2018 edition “Environmental Connection Magazine”.

Abstract
Sediment tracking from construction sites onto public roads and highways is a continual source or frustration for both regulators and contractors. The standard best management practices (BMPs) available, such as stabilized construction entrances and sweepers, often don’t work at all and, at best, only reduce total sediment by 30-50% which is inadequate for preventing water quality violations. In addition to water quality problems, sediment tracking onto roadways can generate dust, which may violate clean air standards and cause unsafe conditions, especially on highways.
This paper will discuss BMPs, methods, and procedures, which can be used by contractors to prevent sediment from being tracked onto roadways in the first place. In addition, ways to significantly reduce sediment loss will be presented. Some of these methods include:

• Passive tire baths
• Various tire washes
• Keeping vehicles of dirt
• Vacuum vs. mechanical sweepers
• Road washing
• Contract specifications

Each method will be discussed with pros and cons, design information and contract specifications.
