But Liberal Democrat Environment spokesperson Tim Farron called the government's announcement "half-baked".
He added that it "doesn't touch the sides in enacting fundamental reform - especially if water companies can still workaround bonuses and wriggle off the hook".
In the last year alone, £7.6m in bonuses were paid to water bosses in England, the government said.
Water UK, which represents companies in the industry, said that firms' independent committees, which decide on performance-related pay, will abide by the laws set by government.
It added: "Water companies are focused on investing a record £104bn over the next five years to secure our water supplies, end sewage entering our rivers and seas and support economic growth."
This week, a review found that the water industry in England and Wales is failing.
The independent Water Commission, led by former Bank of England deputy governor Sir Jon Cunliffe, said in its interim findings that public trust had been shaken by "pollution, financial difficulties, mismanagement [and] infrastructure failures".
Customers have seen bills rocket as water firms try to raise funds to invest in crumbling infrastructure.
The commission said that the UK's water system has suffered "deep-rooted, systemic and interlocking failures over the years".
This included a "failure in government's strategy and planning for the future".
Last month, Thames Water was fined £122.7m for breaching rules over sewage spills and shareholder payouts, the largest ever fine issued by Ofwat.
The highly-indebted company serves about a quarter of the UK's population, mostly across London and parts of southern England, and employs 8,000 people.
Earlier this week, Thames suffered a major blow in an attempt to secure its future after US private equity giant KKR pulled out of a £4bn rescue deal for the company.
In April, campaigners found that the number pollution incidents in England was at a 10-year high.
