MIDDLESEX WATER CO

Our New Jersey and Delaware water supply systems are physically separate and are not interconnected. In New Jersey, the Pinelands System and Fortescue System are not interconnected with the Middlesex System or each other. We believe we have adequate sources of water supply to meet the current service requirements of our present customers in New Jersey and Delaware.

Our Middlesex System produced approximately 13.8 billion gallons in 2023 from:

In November 2021, Middlesex temporarily ceased pumping from its Company-owned wells at the Park Avenue Wellfield Treatment Plant (Park Avenue Plant) in South Plainfield, New Jersey and alternate sources of supply were obtained in order to comply with new State of New Jersey water quality regulations relative to poly- and perfluoroalkyl substances, collectively referred to as PFAS, that became effective in 2021.

Prior to 2021, the Company began design for construction of an enhanced treatment process at the Park Avenue Plant to meet the expected PFAS water quality standards anticipated to be enacted by the State of New Jersey, which at that time were unknown as to their timing and extent. In June 2022, a portion of the enhanced treatment process was completed, placed into service and effectively treated the ground water in compliance with all state and federal drinking water standards. In June 2023, the Company completed the permanent construction of the entire Park Avenue Plant treatment upgrades and placed the upgrades into operation in full compliance with the new State of New Jersey PFAS water quality regulations.

The Middlesex System’s distribution storage facilities are used to supply water to customers at times of peak demand, outages and emergencies.

The principal source of surface water for the Middlesex System is the Delaware & Raritan Canal, which is owned by the State of New Jersey and operated by the New Jersey Water Supply Authority (NJWSA). Middlesex is under contract with the NJWSA, which expires November 30, 2048, and provides for average purchases of 27.0 mgd, with a peak up to 47.0 mgd, of untreated water from the Delaware & Raritan Canal, augmented by the Round Valley/Spruce Run Reservoir System. The untreated surface water is pumped to, and treated at, the CJO Plant.

Water supply to customers of the Fortescue System is derived from two wells, which produced approximately 6.7 million gallons in 2023.

Our Tidewater System produced approximately 2.9 billion gallons in 2023, primarily from 175 wells. Tidewater expects to submit applications to Delaware regulatory authorities for the approval of additional wells as growth, customer demand and water quality warrant. Tidewater augments its water production with annual purchases of up to 60.0 million gallons of treated water from the City of Dover, Delaware. Tidewater does not have a central water treatment facility for the over 470 separate communities it serves. As the number has grown, many of Tidewater’s individual systems have been interconnected, forming several regional systems that are served by multiple water treatment facilities owned by Tidewater.

Pinelands Water System

Water supply to our Pinelands Water System is derived from four wells which produced approximately 134.7 million gallons in 2023. The aggregate pumping capacity of the four wells is 2.2 mgd.
