First, what is "Raw Water"?
Raw water includes rainwater, ground water, and water from lakes and rivers. This water is called "raw" as opposed to water that has been treated to become potable or water which has been used in an industrial process, such as waste water.
Factors to consider in the Cleaning Process For Raw Water
The access port into the system is usually readily established by inserting a tee or a wye fitting, preferably a tee, into the system at convenient point at the beginning or end of the length to be cleaned.
One might be surprised to learn that many raw water systems are cleaned "backward". That is, they are cleaned from the discharge point back toward the source. This often accommodates site and system conditions and helps mitigate or minimize flow disruption in connected segments.
The volume of matter, (minerals, deposits, grit, construction debris, marine growth...) can be much greater than a reasonable person would have expected. Water present during this cleaning will be subject to high turbidity and will have solids in suspension. This makes the water unsuitable for use in the normal treatment process. This is a temporary situation and can be resolved with various customized applications. A decision must be made ahead of time regarding how to contain the solids and dispose of the water impacted by the cleaning process.
