Water Supply and Wastewater Services

The Company’s Regulated Businesses generally own the physical assets used to store, pump, treat and deliver water to its customers and collect, treat, transport and recycle wastewater. Typically, the Company does not own the water. The water the Company treats and delivers is held in public trust and is allocated to the Company through contracts, permits and allocation rights granted by federal and state or multi-state agencies or through the ownership of water rights pursuant to local law. The Company is dependent on defined sources of water supply and obtains its water supply from surface water sources such as reservoirs, lakes, rivers and streams; from groundwater sources, such as wells and aquifers; and water purchased from third-party water suppliers. The level of water treatment the Company applies varies significantly depending upon the quality of the water source and any state requirements that are more restrictive than federal water quality standards. Surface water sources typically require significant treatment, while groundwater sources often require chemical treatment only.

Presented in the table below are the percentages of water supply by source type for the Company’s Top Five States individually and the Regulated Businesses collectively for the year ended December 31, 2024:
