Street sweepers use water primarily for dust control. Water also has a lubricating effect and can help minimize blower or conveyor wear.
The dust control use of water in sweepers is discussed at length in other courses. However, it is worth repeating that minimizing dust is a safety feature. Less dust is safer for the equipment, operator, and the public.
The water sweepers’ use can come from many sources. The sources include “potable” or clean drinking water and “reclaimed” water.
The regulations on where water can be taken or pulled varies widely across the country. In some regions water from fire hydrants is routinely taken without a care. In other regions, the sweeper driver can be arrested, and his sweeper impounded. (Stealing water is no different that stealing a candy bar)
While it is up to your organization to determine how and where to get water to fill your sweeper, it is up to you to ask. Citations, tickets and fines can fall to the operator.
This course does not delve into what region does what, however your supervisor should inform you of these differences. If you are not sure, ask the appropriate person in your organization.
There are often differences between water districts. In Orange County, CA there are 27 independent special water districts. While there are similarities, each one has their own set of rules. Two identical fire hydrants across the street from each other may have different rules. Your region may have far fewer orginizations to deal with.
Module 3 is an in depth discussion on using potable water.
This includes the types of fire hydrants and the concept of a water hammer.
Module 4 discusses using reclaimed water. Using this water in sweepers is a great way to conserve potable drinking water, is cheaper and works just as well.
However, reclaimed water has many more regulations that must be followed. One regulation in many jurisdictions is that the sweeper operator must be trained in its use.
This course is intended to provide that training. The caveat we mentioned above is that each water district has its own rules or flavor of what qualifies as meeting its training requirements.
If the district(s) you work in have additional features to their training requirements, please forward that information to NAPSA for consideration to include it here. Back to: Water For Sweepers
