Lead Service Line Inventory Instructions
Community and non-transient, non-community public water systems must complete and submit to the state a lead service line inventory by October 16, 2024.
The LCRR requires certain public water systems to identify the service line materials of all service connections in their distribution system regardless of ownership status. The rule determines the minimum information required to be needed in your lead service line inventory, how to communicate about your system inventory, and how often to update the inventory. It may be more useful to the system while conducting their inventory to gather additional or more detailed information than required and we have provided a spreadsheet with required information needed for compliance and a detailed spreadsheet with information we recommend water systems complete and keep on hand to be prepared for customer questions, asset management, or future rule revisions.
SWIFT Submittals Application
The New Mexico Environment Department has chosen to use the SWIFT Submittals application to help public water systems submit their Lead Service Line Inventories (LSLI) to the state by the October 16, 2024 deadline. SWIFT Submittals can also be used by water systems to continually manage and update their LSLIs.
Public Water Systems can register for the SWIFT Submittals application here: Register Here
To help water systems use SWIFT Submittals, NMED has developed a tutorial video that explains the registration process and how to use the application. You can access the video here: SWIFT Submittals Tutorial Video
Lead Service Line Inventory Status Definitions
Single Ownership | Single ownership means that the service line is owned entirely by either the public water system or the property owner. There is no shared responsibility for the service line. |
Split Ownership | Split ownership means that the service line is owned jointly by both the public water system and the property owner. Responsibility for the service line is shared. |
