What can cause sediment build-up in a water distribution system?

Sediment build-up in a water distribution system is primarily caused by low flow velocities and stagnant water. When water flows slowly or remains stagnant, sediment, minerals, and other particulates have the opportunity to settle out of the water and accumulate at the bottom of pipes or tanks. This can lead to blockages, decreased water quality, and an increase in the need for maintenance and cleaning of the distribution system.

In contrast, high flow velocities typically keep sediment suspended and moving through the system, thereby preventing accumulation. Excessive rainfall and runoff can introduce additional sediment and debris into the water system, but it does not directly cause build-up in the same manner as stagnation does. Regular usage and maintenance help to ensure that sediment does not accumulate excessively, promoting better water flow and quality.
