If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate)

[X] (a) The reasons described in reasonable detail in Part III of this form 
could not be eliminated without unreasonable effort or expense;

[X] (b) The subject annual report, semi-annual report, transition report on Form
10-K, Form 20-F,11-K or Form N-SAR, or portion thereof, will be filed on or

[_] (c) The accountant's statement or other exhibit required by Rule 12b-25(c)

PART III -- NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,
N-SAR, or the transition report portion thereof, could not be filed within the
prescribed time period. (Attach Extra Sheets if Needed)

Middlesex Water Company (the Company) was not able to file within the prescribed
time period because of additional time required to complete the restatement of
its Condensed Consolidated Balance Sheet as of December 31, 2004, and its
Condensed Consolidated Statement of Cash Flows for the nine-month period ended
September 30, 2004. As part of its financial reporting process review,
management determined on November 5, 2005 that the Company needed to restate its
consolidated financial statements. The Company expects to file its Quarterly
Report on Form 10-Q for the period ended September 30, 2005 on or before the
fifth calendar day from the original required filing date of November 9, 2005.
In addition, the Company intends to amend the Consolidated Balance Sheets as of
December 31, 2003 and 2004 and its Consolidated Statements of Cash Flows for the
fiscal periods ended December 31, 2002, 2003 and 2004, originally filed in its
2004 Annual Report on Form 10-K for the Fiscal Year Ended December 31, 2004 and
its Condensed Consolidated Balance Sheet and Condensed Consolidated Statements
of Cash Flows originally filed in its Quarterly Reports on Form 10-Q for the
periods ended March 31, 2005 and June 30, 2005, as soon as practicable.

The Balance Sheet as restated will include previously unrecorded non-cash
contributions of utility assets from developers and the related construction
advance or contribution. Previously, the Company had recorded these transactions
as of the date the cost and other information regarding the contributed property
was received from the developer rather than the date the Company took ownership
of the contributed property.

The Statement of Cash Flows as restated will exclude disclosure of non-cash
activity within the statement. The previously reported cash flow information for
the nine months ended September 30, 2004 included non-cash activity for
construction advances and contributions for utility plant.

The restatement does not have any effect on net income, earnings applicable to
common stock, cash flow from operations, or liquidity.
