GMB, the union for water workers, is calling on Severn Trent water to be investigated following claims that 500 job cuts have led to leakages and depleted stocks.
They estimate water usage went up by 20% in the last year and claim that job losses and the introduction of a number of cost saving initiatives are behind a 'failure' to control leakages.
But Severn Trent Water, whose headquarters are in Coventry, says job losses have not affected the number of front-line staff and add that teams aim to fix leaks within 24 hours.
The restructuring of the business earlier this year didn't reduce the number of front line staff and so far this year we've had more gangs than ever working to find and fix leaks across the region. Over the last five years we've seen a ten per cent decrease in our leakage levels and our focus going forwards is to bring that level down even further and to fix as many leaks as possible within 24 hours.
"Leakage is one of a number of performance measures we report on an annual basis to OFWAT and our performance is published on our website. Prior to publication our leakage performance is subjected to rigorous assurance processes performed by a recognised external body.""Overall our water resources are in a healthy position for this time of year and we don't anticipate any supply problems over the winter."
Residents in Telford who complained about a fishy smell coming from their drains have been told it was caused by dead piranhas, which had likely been flushed down the toilet.
Severn Trent Water says, when it investigated the sewers in Madeley, it also found a number of other dead fish.
It is not the first time sewers in Shropshire have been blocked by odd items - in January sewers in Ditton Priors, near Bridgnorth, were found to be blocked by piles of pants that had been flushed down the toilet.
Sue Fulford, customer operations manager for Severn Trent Water said: "The drains that take waste water away from your home are only a few inches wide and are only meant to take water, toilet roll and human waste.
"Toilet roll is meant to break down when it gets wet so it washes easily through the system."
Severn Trent have said the rain and storms over the last few days have led to an increase in calls form customers.
Extra staff are working at the firm's call centres and additional teams are being used on the ground to deal with flooding issues.
The company supplies water to more than four million households across the Midlands.
The water supply to thousands of homes across Birmingham is "slowly being restored" to normal following a major water mains burst, Severn Trent Water have said.
The firm has urged people to stay patient as it may still take time for the network to fill back up.
A spokesperson also warned people their water might be slightly yellow or orange - but said there was no imminent risk to health and it should return to normal if left running for a few minutes.
We will of course be monitoring this, but if you should experience a slight yellow/orange discolouration, please don’t worry.
If you do experience any discolouration, just leave your cold tap running for a short period (usually about 20 minutes) and your supply will return to normal.
We’d like to thank all of our customers for their patience – we know it can be a real inconvenience to be without a water supply and we’re really sorry for any problems this has caused.
Supermarket shelves are being emptied of bottled water as homes in Birmingham have been left with little or no supply since this morning.
Thousands of homes in the city have been hit by supply issues after a water main burst earlier today.
Severn Trent Water has said it is moving water around the network and bringing in a fleet of tankers to try to restore water supply as soon as possible.
They hope to get 2,900 homes in Great Barr back up and running within a couple of hours, along with 1,500 homes in Northfield.
A further 2,700 houses in the Bartley Green and Woodgate areas and 600 in Selly Oak have also been affected.
Thousands of people across Birmingham are this afternoon without water after a "large water main" burst.
Almost 8,000 homes in Great Barr, Northfield, Selly Oak, Bartley Green and Woodgate are among those who have no water or low pressure.
A spokesperson for Severn Trent Water said engineers were now on site and trying to find a solution.
We’re really sorry and hope this isn't causing too much trouble.
We are doing all we can to restore supplies as quickly as possible.
Our incident team have identified some options to restore some supplies and are putting these plans into action.
A ranger has told of staff's excitement after a rare albino squirrel set up home at a Warwickshire waterway.
The ghost-white squirrel has been spotted at Draycote Water, near Rugby, in recent weeks - and the ranger has finally managed to capture it on camera.
We’ve been all of a flutter since the ghostly white squirrel was spotted at Draycote Water.
Visitors were reporting sightings of the albino rodent, but as with spectres it was proving difficult to capture on camera.
Because of its white colouring it does standout against the autumnal colours here, but it moves so fast, photographing it was very difficult
Just before Halloween, we can’t believe that this rare rodent has made Draycote Water its new haunt.
We hope that it will stay around for the half term holidays so that all of the local children can have a chance to see it.
A rare 'ghost' squirrel has made a Warwickshire waterway its new haunt.
Visitors to Draycote Water, near Rugby, have spotted flashes of white as the creature settles in to its new home less than two weeks before Halloween.
Until now, however, it has avoided being caught on camera.
Severn Trent Water ranger Thomas Crawford finally managed to snap the squirrel as it hunted for food.
The albino grey squirrel is one of just 50 thought to be alive in the UK.
A burst pipe at Severn Trent's Chaddesden reservoir left thousands of homes in the Chaddesden and Spondon areas of Derby without water.
Following a three-hour repair operation Severn Trent had repaired the burst by 8am.
Severn Trent Water say they have dealt with double the number of calls during the recent heavy downpours. Seventy percent of the calls turned out to be unnecessary. Watch Andy Bevan's full report.
