Every day Scottish Water-the only publicly-owned water utility in Great Britain-pumps about 304 million gallons of drinking water to about 2.5 million households and 153,000 businesses across the nation. That's enough water to fill more than 500 Olympic-size swimming pools. The utility also handles the resulting waste water, taking away and treating about 204 million gallons daily. The whole job engages the efforts of some 4,000 employees-everyone from customer service agents to sewer workers to infrastructure planners.
