Sarah Heald, South West Water's chief strategy and regulation officer, has told the BBC improvements to the region's water quality will be a team effort.

She adds the the Cunliffe Report published into the water industry could help provide change in the future.

Ms Heald says: "I think as we all saw yesterday with the Cunliffe review, we all recognise that a reset moment is required in the industry. And not just in our industry.

"I think one of the great things that came out of the report is it recognises that the water system is indeed that - it's a system that has many stakeholders of which we are one.

"We are custodians of clean and wastewater in this region, but have others in this region who also have responsibility and we all need to work together to improve the quality of our water ways."

Tim Selbie was about to dive into the water at Devil's Point when he spoke to me.

The 66-year-old who lives in Plymouth says he tries to go out in the sea once a day between March and October as it was a "lovely environment" to be in and helps bring him peace of mind.

He says there were sometimes issues due to sewage overflows impacting the water quality.

"I avoid going out after heavy rain and leave it to settle down again after a couple of days."

He feels South West Water prioritises shareholders over updating its equipment, which would take a "very long time" to sort out.

Mr Selbie says the company needed to think about the number of tourists who visit the area as well and want to swim in the sea.

"The system's at bursting point, probably," he adds.

I'm in Cawsand on the Rame Peninsula in Cornwall and it's absolutely beautiful.

I'm sitting on a wooden bench and there's a child with a snorkel and a wetsuit who's just dipped under the water.

There's a boat which has been on a trip and dropped people off before going off again.

People are queueing up to have an ice-cream, so it's pretty stunning and fantastic.

There was a little bit of drizzle earlier, but the sun's come out a bit and it's looks absolutely splendid.

I've been talking to people here and they've said water quality is "super important".

One trader I've spoken to said it is one thing tourists check before they arrive and they expect good quality water and want to know if they can go into the water safely.

A paddleboard instructor has been speaking to BBC Radio Cornwall's James Churchfield about how water quality affects her line of work.

While I was down at Devil's Point in Plymouth, I spoke to local 70-year-old sea swimmer Colin Hargreaves moments after he got out of the water.

He says he loves sea swimming and does it three or four times a week, with benefits for both his physical and mental health.

However, there have been times when he has spotted sewage out in the water while swimming.

"Sometimes there's a smell and sometimes there's a patchy scum that you have to be a bit aware of," he says.

Mr Hargreaves adds he would like to see South West Water make more improvements to the networks they operate.

He says: "We get these stories from the media about bonuses and the bills are going to go up again, but we can't swim in the sea sometimes.

"I think they need to try harder [to make improvements] and it needs to be quite obvious. We need to be seeing it happen."

If you're just joining us, here is a quick recap of some of the top lines from earlier:

• Hannah Pearson, from Friends of the Dart river in Devon, says swimmers had reported getting unwell after being in the local water

• South West Water says housing developments are having an impact on their network and it also confirmed there were no plans for a hosepipe ban

• A Cornwall charity says it wants better access to grants awarded from water company fines

The outbreak of cryptosporidium in and around Brixham last year cost South West Water (SWW) about £21m.

Pennon Group, which owns SWW, reported a pre-tax loss of £72.7m for the year to the end of March 2025, which was up from a £9.1m loss reported the previous year.

It said a large portion of the loss was linked to costs around the outbreak of the parasite, which left more than 100 people suffering from a diarrhoea-type illness.

In May SWW boss Susan Davy apologised unreservedly over the outbreak.

Figures from the Environment Agency in March show the duration of storm overflow usage in the South West Water region was the highest it's been in five years.

The duration increased to 544,000 hours in 2024 from 531,000 in 2023.

The water firm says it is spending about £760m over the next five years to tackle the problem.

I was in Devil's Point in Plymouth where I found a father and daughter admiring the view across the water.

Carrie Smith, a former civil engineer who was visiting her father, says planning for sewage overflows has been "part of life".

"If your sewers are going to overflow, it's better to overflow into water rather than up the street," she says.

"You need the upkeep of your infrastructure and perhaps that hasn't been done successfully."

John Prisk believes the issue is "over-hyped".

"Sometimes the more vociferous you are, the more attention you get," he says.

"The people who are happy swimming don't complain about it."

In June, thousands of fish including trout, eels and lamprey died in the St Austell River – also known as the White River.

Pennon Group said the pollution was caused by “a delivery by a third party to our treatment works” in the Pentewan Valley.

On 1 July, the Environment Agency said it was investigating another incident involving fish killed by pollution in the River Lew, near Okehampton, which had been reported the previous day.

An agency spokesperson said about 90 fish died.

Over the border resources in the Wessex water catchment area are well below average.

An average of 46mm of rain fell across the catchment area in June - 76% of the long-term average

This is the fourth consecutive relatively dry month, resulting in the driest four-month period from March to June since 1976, and the fourth driest four-month period since records began in 1871

Both Wessex Water and Bristol Water reservoir levels continued to decrease throughout June.

The combined levels at the end of June for Wessex Water were approximately 71% capacity, while combined levels were about 66% capacity for Bristol Water.

For both water companies this is notably lower than reservoir levels recorded this time last year. For Wessex Water, reservoir levels at the end of June are slightly higher than this time of year in 1995 - considered a major drought year. For Bristol Water, levels are lower than at the end of June 1995.

Swimmers share what they love about getting in the water in Cornwall and what they want to change.

South West Water says it receives alerts when its storm overflows start to spill.

The utility says this means it can spot issues issues in the network and respond as necessary and it has a website which provides information on all storm overflow locations across the region, external and whether they are active.

I caught up with Robert after he came out of the water on Gyllyngvase Beach.

He's on holiday from York and says he never checks water quality before he swims, telling me: "I almost prefer not to know.

"The water looks quite clear to me but I guess that might be concealing things that I don't want to know about.

"It was beautiful, very refreshing."

Harry and Tamzin, who live in Bristol, were spending some of their holiday on Gyllyngvase Beach in Falmouth.

They say they usually check the Surfers Against Sewage website but did not this morning.

Tamzin says: "We've just been in and it felt lovely, it looks nice and it looks clean."

They told me they are originally from Southampton, where they swam in the Solent.

Harry says: "The Solent is notoriously not very clean and there's been periods where we haven't been able to swim down there because it's not been clean enough, the water quality has been too low.

"I generally feel better the more west we get - I don't know if that's true but it just generally feels nicer."

Throughout the day we are taking a close look at water quality issues in Devon and Cornwall. If you're just joining us here's a quick look at what's happened so far:

• Swimmers are calling for real-time testing of water quality

• Speaking on BBC Local Radio, South West Water says billions is to be invested over the next five years to improve the network
• A Cornwall charity says it wants better access to water company fines
• Campaigners are calling for action at the River Otter, which has the highest phosphate levels of any major watercourse in Devon and Cornwall

I caught up with swimmer Gilly Mead after her dip at Gyllyngvase Beach in Falmouth.

She lives near Stithians and swims at least once a week "when the mood takes me".

Earlier this morning the water was "a bit murky" - but she says "that's not anyone else's fault, just the weather".

Her friend regularly checks water quality apps but she says she prefers just to get in.

"I just take the risk, really," she says.

The government describes storm overflows as "safety valves" built into the combined sewer system.

When there is extensive rainfall, excess sewage is discharged into rivers, lakes or the sea through the system.

This protects properties from flooding and stops sewage backing up in homes and streets, the Department for Environment, Food and Rural Affairs says.

Campaigners say discharges from storm overflows can contain raw sewage which can contain high levels of harmful bacteria and viruses, and other pollutants such as microplastics and pharmaceuticals.

I've been on Gyllyngvase Beach in Falmouth speaking to swimmers about the quality of the water.

Angela Ratcliffe, who lives in the Cornish town, told me she gets in the water nearly every day.

"I'm disabled and so if I get in there I'm not disabled," she says.

"I can do exercises and everything in there without being in pain."

She says she loves the water but she knows when not to get in.

"At home I look out and can see a brown slick going across and quite often there's a lot of scum," she says.

"I think it's because they've built so many houses - the infrastructure cannot take it."
