Work is now underway to repair a mains pipe after about 800,000 litres of wastewater was spilled into Lake Taupō earlier this week.
However, local residents are still being advised to take extra caution when using water. That includes flushing the toilet as little as possible, taking shorter showers and reducing laundry loads.
A Taupō District Council spokeswoman said repairs to the wastewater main began this morning. The system was expected to be operating as normal within three weeks.
"The burst wastewater pipe remains sealed and wastewater is being pumped around the break at the bottom of Tongariro St so it can carry on to the wastewater treatment plant," she said.
The council still does not know why the water main burst, but it was being investigated.
"The broken pipes will be recovered from the spill site and tested, and the cause of the breakage investigated," the spokeswoman said.
The road closure on Tongariro St has now been shifted south to allow greater vehicle access and parking by the shops on the lakefront.
The lakefront continues to be closed from the intersection with Ruapehu St.
Businesses are still open and operating as usual.
The council spokeswoman said they expected the clean-up of the contaminated beachfront to begin this weekend or on Monday.
"The council is working closely with Tūwharetoa Māori Trust Board and Waikato Regional Council on the most efficient methodology to clean the beachfront spill site and lake floor in that area."
A rāhui restricts public access to the spill site. The tourism businesses on the lakefront and down the Waikato River remain open for business but are modifying their offerings where necessary to take account of the rāhui.
The district is expecting an influx of visitors and holiday home owners over the upcoming school holidays. The popular Malcolm Flowers Insurances Taupō Winter Festival also started earlier this week. Festival director Nicola Carter said last week all 32 of the festival events would go ahead as planned.
