Asset Management

The objectives of this project are to evaluate technologies and to develop a prototype capable of identifying service line materials.

A comprehensive literature review was conducted in order to identify new technologies capable of discriminating the buried metals, a vendor investigation has been completed, and more.

Field studies are being conducted or have been completed at 10 public water systems in the United States and Canada.

Two sets of lead pipes are being conditioned for use in studying the timing and mechanisms for orthophosphate to effectively control lead concentrations.

October 2017-March 2018 - The technique identified is the resistance measurement of a pipe.

January-March 2019 - After conclusive experimentation in the laboratory, testing in the field has begun. The equipment used for laboratory experiments was modified for usage in the field.

Determine baseline occurrence of Legionella throughout the Passaic Valley Water Commission (PVWC) water distribution system.

The new lead pipes have now been conditioned to a stage at which a substantial scale of lead(IV) oxide (PbO2, plattnerite) has been developed and is maintaining both total and dissolved lead concentrations at consistently low levels.

Work continued on Task 1 Collect and Analyze Utility Billing Data and Meter Sizing Methods.

November 15, 2017 – May 15, 2018 - A report was drafted to provide background and context on alternative water supplies to workshop participants so that all attendees have general knowledge heading into the workshop. This report was sent to the PAC for review.
