YORKSHIRE Water is to spend £133m improving water services in Kirklees.
The company has launched a massive investment programme to upgrade water treatment, replace thousands of kilometres of mains and repair the sewer network.
The work is part of a £1.5bn investment package promised by Yorkshire Water over the next five years.
The £133m package of measures for Kirklees will include more than £1.8m to be spent upgrading water treatment works, including one at Holmbridge.
Another £5.1m will go towards replacing more than 65 kilometres (40 miles) of water mains in the district, while £21m will be spent on improving sewage treatment works, including ones at Deighton and Clayton West.
There will also be repairs to the sewage system, to help combat flooding around Kirkburton and Dewsbury.
The biggest single investment will be the £90m pumped into the waste water treatment works at Cooper Bridge and on smaller projects to improve the quality of storm water discharged from sewers into rivers and streams after heavy or prolonged rain.
More walks across the company's 72,000 acres of land will be opened to the public, with work to improve paths around reservoirs to meet the needs of disabled people, cyclists and horse riders.
Managing director Kevin Whiteman said the size of the investment answered criticism that the company was making too much profit and raising its bills too high.
Earlier this week, Yorkshire Water unveiled a 16.8% rise in profits to £223.7m for the year to March 31. That follows a settlement with regulator Ofwat to raise bills by 18% in the next five years to about £288 by 2010.
Mr Whiteman said: "We have to keep prices as low as possible, while keeping the regulator happy and providing an adequate return for our shareholders. We also need to raise cash to fund the investment programme."
