AMERICAN WATER WORKS CO INC

American Water Works Co Inc leverages its status as the nation’s largest investor-owned water and wastewater utility to deliver treated water, infrastructure maintenance, and regulatory compliance services to municipalities, neighborhoods, business parks, and critical industrial campuses across the SIC 4941 water supply universe. With a network of reservoirs, treatment plants, and distribution systems, the company focuses on reliability, conservation support, and metered billing tailored to residential, commercial, and industrial customers who depend on safe, uninterrupted delivery. Its operations are governed by a complex tapestry of state public utility commissions, federal environmental statutes, and health standards, and management consistently flags capital intensity, aging pipelines, and rate case timing as material risks that can affect service quality and returns. The latest publicly referenced disclosure is the Form 10-Q filed in November 1999, which still underscores regulatory oversight and the imperative of funding reinvestment.
