About Our Presentation

Colored water in the distribution lines can be the bane of many a water agency. When caused by iron or manganese in the system, the reddish-brown cast will immediately raise concerns for customers throughout the service area. It’s a situation that must be addressed and cleared up immediately, lest it negatively impact both the infrastructure and public confidence.

For the City of Buena Park, the impact of colored water on its system has been an ongoing concern. Despite meeting all state and federal regulatory requirements for drinking water, the appearance at times of colored water within its system threatens the City’s great relationship with its customers.

To address this sporadic issue, the City enlisted Hazen and Sawyer (Hazen) to assist with evaluating water quality data, and to develop several options to remedy the discolored water.

The City, after discussion with Hazen, decided to start first with a test program for unidirectional flushing.

Unidirectional flushing (UDF) cleans the water lines by harnessing the power of the water itself. By closing off select valves and opening specific hydrants, water is directed down a single water main. The concentrated pressure creates enough velocity to scour the pipe and flush all sediments away. Properly applied, UDF both cleanses the system and uses less water than conventional flushing. The result is enhanced water quality, improved pipe capacity, and better operation of the entire system.

As the City was already using pipeline flushing, it requested Hazen develop a test program to evaluate the effectiveness of UDF in two service tracts. Hazen developed UDF journals and assisted with field sampling to evaluate the program’s results.  From this initial study, the City hoped to determine if UDF is the right approach for addressing discolored water.

So join us, September 16, for a revealing look at the early development of a useful technique that promises savings of time, money, and water. And above all, it’s a process that helps ensure goodwill throughout the service area.
