INTRODUCTION

An area of great confusion for many NAVFAC Utilities and Energy Management (UEM) customers is the point of demarcation between facility systems and the NAVFAC UEM utility system. This service point (Demarcation) is the point of connection between the serving utility and the facility and is where ownership changes. This is the transition between NAVFAC UEM and customer funding for Sustainment, Restoration, and Modernization.

The NAVFAC Real Property Inventory Procedures Manual (P-78) defines a Utility System as ‘A system which generates and/or distributes a commodity and makes that commodity available to more than one facility’. It further defines Facility property by a building, structure, or linear structure out to an imaginary line surrounding a facility at a distance of five feet from the foundation that, barring specific direction to the contrary such as a utility privatization agreement, denotes what is included in the basic record for the facility (e.g., landscaping, sidewalks, and utility connections). This imaginary line is what is commonly referred to as the ‘five-foot line.’

The intent of this document is to supply specific direction that clearly defines the demarcation point between utility and facility systems, and replace the ‘five foot line’ rule with more practical, standard guidance.

Clear demarcation is in the best interest of the Installation, Supported Commands, and NAVFAC UEM because it allows proper alignment of Sustainment, Restoration, and Modernization funding with the appropriate Maintenance Responsible UIC. Clear demarcation also helps communicate what services are included in the Navy Working Capital Fund (NWCF) utility rates and what is the responsibility of the facility owner.

The Points of Demarcation and ownership set forth in this document does not apply to sites where a negotiated agreement exists, such as Public Private Venture (PPV) housing, Municipal/Mutual Service Agreements [MSA], Letters of Agreement [LOA], and Memorandum of Understanding [MOU]. However, the Points of Demarcation and ownership set forth in this document must be considered when developing new agreements.

The Points of Demarcation and ownership set forth in this document does not apply to sites where Utility Service is supplied and distributed to facilities by an outside service provider.

Everything beyond the outside service provider’s point of demarcation, typically the provider owned meter, is owned by the facility.
