More Clean Water Diversion Best Management Practices

This shows several simple water diversion berms in action during a heavy rain. While the construction project is complete and the grass has grown, you can see how they prevented erosion during the project when bare dirt was exposed to rain.

Vacuum Sweeper Maintenance

If I specify a vacuum sweeper on a construction project, I expect it to be operational.

I require all systems to be functional per manufacturers specifications.

If not, the sweeper goes away, maybe the job is shut down, until a working sweeper is brought to the site.

Specifications:
1) Power brooms shall not be utilized without prior approval by
the Engineer.

2) Contractor shall have sufficient working vacuum sweepers on
site at all times work is being performed.

3) All sweepers shall have on-board water spray systems that
shall be operating at all times.

4) systems shall function per manufacturer specifications
including, but not limited to, spray water systems, blowers,
vacuum nozzles, hoses, debris hopper, hydraulics and
electrical.

5) At no time shall debris hopper seals leak debris and liquids.

Why Power Brooms are a Bad Idea

As you can see, these types of sweepers don’t pick up dirt and sediment from asphalt, they just spread it around.

Water spray system attachments help some but then the sweeper mostly turns the dirt to mud and smears it around.

These are useful for picking up gravel and sand.

A vacuum sweeper is the way to go.
