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.

Not What an Inspector Wants to See

I just did a quick, random, drive-by of a job and this is what I saw. This might tell me that the construction staff, owner and contractor, don’t understand what is required or, haven’t read the TESC specifications.

Since this was a random, unannounced, drive-by, I might think that this is not an isolated incident. While I prefer a site be kept clean, as long as stuff doesn’t leave the project boundary, I don’t have an issue. However, by not keeping the site clean, trackout is inevitable.

Also, note the Bobcat broom sweeper just inside the fence on the left; these are great for pushing dirt around and up in the air but we only allow vacuum sweepers on projects, so I don’t know why this is on site.

I sent an email to the engineer suggesting that everyone might want to review the TESC spec. and take necessary actions so this doesn’t keep happening. Also, rain is forecast for tonight.

Denver Dirt Pile

Just a nice dirt pile in Denver. Walking around between presentations at the International Erosion Control Conference in February 2019 and saw this. A little utility work in the street, going to reuse the excavated dirt, placed it on plastic, put some berms around base, no rain in the forecast and the dire goes back in the hole later in the day so no need for cover.

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
