A Culture of Continuous Improvement
Working at a California Water Service Group subsidiary isn’t just a job. We hire, retain, and develop our talent to become future leaders in the water industry. Through our Continuous Improvement program, employees at all levels can identify opportunities to improve the way we do business, and use their analytical and collaborative skills to develop solutions that may be implemented locally or Company-wide.

Culture is an important part of our Company’s success, and we wanted to make sure we carried our special culture forward to new generations of employees as our baby boomers, many with decades of knowledge and experience, began to retire. We formed a cross-functional team of employees, with varying levels of experience, tenure, and positions to help define what makes our culture so special. We also align our hiring strategies with our core values of integrity, service, innovation, safety, corporate citizenship, respect and collaboration, agility, and commitment to provide quality, service, and value to all of our employees, who in turn provide quality, service, and value to our customers and communities.

Diversity, Equality, and Inclusion
We Support Veterans, Value Diversity, and Provide Reasonable Accommodations
Our employees are our company's most valuable asset. We hold high importance on enhancing each employee's quality of life by implementing programs aimed at promoting diversity, equality, and inclusion. We promote a culture of inclusiveness and expect all employees to be respectful of each other’s cultural differences. Our philosophy is to treat all employees fairly and with respect and dignity. Our diverse workforce reflects the communities that we serve.
