Rate and Regulatory Matters [Abstract]
Rate and Regulatory Matters	Note 2 – Rate and Regulatory Matters Middlesex - On March 31, 2015, Middlesex filed a petition with the New Jersey Board of Public Utilities (NJBPU) seeking permission to increase its base water rates by approximately $9.5 million per year. The request was necessitated by declining consumption in its Commercial and Industrial class customers, increasing costs for active and retired employee benefits, capital infrastructure investments Middlesex has made, or has committed to make, and regulation-driven increases in other operations and maintenance costs. We cannot predict when and whether the NJBPU will ultimately approve, deny, or reduce the amount of the request. Under New Jersey statute, the NJPBU must render a decision within nine months of a petition filing. Middlesex has in place a NJBPU-approved foundational filing (Foundational Filing) that allows the Company to implement a Distribution System Improvement Charge (DSIC) in six-month periods over three years. A DSIC is a rate-mechanism that allows water utilities to recover investments in, and generate a return on, qualifying capital improvements to their water distribution system made between base rate proceedings. The maximum annual revenue allowed to be recovered under the approved Foundational Filing is $3.6 million. The DSIC rate for the first six-month period of qualifying expenditures is expected to generate annual revenues of $0.3 million and be effective in May 2015. Tidewater - Effective January 1, 2015, Tidewater implemented a Delaware Public Service Commission-approved DSIC rate increase that is expected to generate $0.1 million of annual revenues.
