YORK WATER CO

Source of Water Supply

The Company obtains the bulk of its water supply for its primary system for York and Adams Counties from both the South Branch and East Branch of the Codorus Creek, which together have an average daily flow of approximately 73.0 million gallons from a combined watershed area of approximately 117 square miles. The Company owns two impounding dams on this primary system located in York and Springfield Townships adjoining the Borough of Jacobus to the south. The lower dam, the Lake Williams Impounding Dam, creates a reservoir covering approximately 165 acres containing about 870 million gallons of water. The upper dam, the Lake Redman Impounding Dam, creates a reservoir covering approximately 290 acres containing about 1.3 billion gallons of water. The Company supplements these reservoirs with a 15-mile pipeline from the Susquehanna River to Lake Redman which provides access to an additional supply of 12.0 million gallons per day, or MGD.

The Company obtains its water supply for its system for Franklin County from the Roxbury Dam on the Conodoguinet Creek, which has an average daily flow of approximately 26.0 million gallons from a watershed area of approximately 33 square miles. The Company has a reservoir on this system which holds up to approximately 330 million gallons of water.

The Company also owns satellite groundwater systems in York, Adams, and Lancaster Counties. The systems consist of thirteen wells capable of providing a combined safe yield of approximately 808,000 gallons per day.

As of December 31, 2023, the Company’s present average daily availability was 41.0 million gallons, and daily consumption was approximately 21.8 million gallons.

Pumping Stations

The Company’s main pumping station is located in Spring Garden Township, York County, on the south branch of the Codorus Creek about four miles downstream from the Company’s lower impounding dam. The pumping station houses pumping equipment with a combined permitted capacity of 42.0 MGD. A large diesel backup generator is installed to provide power to the pumps in the event of an emergency. The untreated water is pumped approximately two miles to the filtration plant through pipes owned by the Company.

The Susquehanna River Pumping Station is located on the western shore of the Susquehanna River in York County, several miles south of Wrightsville. The pumping station houses pumping equipment with a combined permitted capacity of 12.0 MGD. The pumping station pumps water from the Susquehanna River approximately 15 miles through a combination of 30 inch and 36 inch ductile iron main to the Company’s upper impounding dam, located at Lake Redman.

The Lake Redman Pumping Station is located in York Township, York County, adjacent to Lake Redman. The pumping station is designed to provide a redundant source with permitted capacity to pump 20.0 MGD of untreated water through a company-owned 36 inch force main approximately 3.5 miles to the filtration plant, meeting the Company’s daily consumption needs.

Treatment Facilities

The Company’s primary water filtration plant is located in Spring Garden Township, York County, about one-half mile south of the City of York. Water at this plant is filtered through twelve dual media filters having a rated capacity of 39.0 MGD, with a maximum supply of 42.0 MGD for short periods if necessary.

The Company’s sediment recycling facility is located adjacent to this water filtration plant. This state of the art facility employs cutting edge technology to remove fine, suspended solids from untreated water. The Company estimates that through this energy-efficient, environmentally friendly process, approximately 600 tons of sediment will be removed annually, thereby improving the quality of the Codorus Creek watershed.

The Company also operates a water filtration plant in Greene Township, Franklin County. Water at this plant is filtered through filters having a rated capacity of 1.16 MGD.

Based on a total average daily consumption in 2023 of approximately 21.8 million gallons, the Company believes the water pumping and filtering facilities are adequate to meet present and anticipated demands.

The Company has ten wastewater treatment facilities located in four counties within south-central Pennsylvania. The wastewater treatment plants range from small extended aeration package plants to three larger facilities that utilize Biological Nutrient Removal/tertiary treatment technology, and have a combined permitted flow capacity of 922,500 gallons. With a projected maximum daily demand of 389,000 gallons, the plants’ flow paths offer both capacity and operational redundancy for maintenance, high flow events, and potential growth.

Distribution and Collection

The distribution systems of the Company have approximately 1,076 miles of water main lines which range in diameter from 2 inches to 36 inches. The distribution systems include booster stations and standpipes and reservoirs capable of storing approximately 59.7 million gallons of potable water. All booster stations are equipped with at least two pumps for protection in case of mechanical failure. Following a deliberate study of customer demand and pumping capacity, the Company installed standby generators at all critical booster stations to provide an alternate energy source or emergency power in the event of an electric utility interruption.

The thirteen wastewater collection systems of the Company have approximately 102 miles of gravity collection mains and pressure force mains along with redundant sewage pumping stations.

Other Properties

The Company’s distribution center and material and supplies warehouse are located in Springettsbury Township and are composed of three one-story concrete block buildings aggregating 30,680 square feet.

The administrative and executive offices of the Company are located in one three-story and one two-story brick and masonry buildings, containing a total of approximately 21,861 square feet, in the City of York, Pennsylvania.

All of the Company’s properties described above are held in fee by the Company. There are no material encumbrances on such properties.

In 1976, the Company entered into a Joint Use and Park Management Agreement with York County under which the Company licensed use of certain of its lands and waters for public park purposes for a period of 50 years. Under the agreement, York County has agreed not to erect a dam upstream on the East Branch of the Codorus Creek or otherwise obstruct the flow of the creek.
