Inspections without notice, regular MOT-style checks and compulsory water efficiency labels on appliances are among the key measures in the government's overhaul of the water industry.
The government is describing the measures as the biggest overhaul of the water industry in England and Wales since privatisation.
Environment Secretary Emma Reynolds said there would be "nowhere to hide" for poor performing water companies.
The proposed changes come after widespread public anger at increasing numbers of pollution incidents, leaks and water outages that have affected thousands of customers across England and Wales in recent years.
