HUDSON — The city’s 2.55 million gallon water supply will be back at full capacity by Wednesday and the cleaning device stuck in the water main will stay there until later in the summer, according to Superintendent of Public Works Robert Perry.
The city forecasted the tank would be full by early morning Tuesday, but an increase in water use because of high temperatures Monday slowed down the process, Perry said.
“Clearly people were using a lot of water,” he said Tuesday.
The city announced Monday the water tank would be full that night.
“We’re basically there,” Perry said late Tuesday morning.
The tank is about 100,000 gallons below full capacity, or 2.45 million gallons full, Perry said late Tuesday morning.
Tuesday’s rain was helpful for the city, he said.
“Nobody will be watering gardens today for sure,” he said.
The city’s water supply was disrupted when a poly-pig cleaning device got stuck in the city’s water main Tuesday. After workers could not retrieve the device Tuesday or Wednesday, they redirected their efforts to filling the city’s water tank. Water quality was not impacted.
The poly-pig is the full diameter of the water main and is pressurized and forced through the city’s 120-year-old pipes, Perry said. The device is used to clean the water main annually and while there have been problems with the process over the past decades, there has not been an emergency like this, Perry said.
“It’s kind of a violent process and things can happen,” Perry said Wednesday.
The device has been lodged in a T-shaped section of the piping at the Claverack pump station.
The water tank was reaching 50% capacity Thursday and made it to 60% Friday morning.
The poly-pig remains stuck and likely will not be retrieved until August as the city waits on supplies to retrieve the pig, Perry said Tuesday.
While some components are in stock, the T section that needs to be cut out and replaced has a projected delivery date of Aug. 23.
“We’ll try some other suppliers, but after a year of COVID, these global supply chains are all disrupted,” Perry said. “There are huge lead times with a lot of stuff.”
The city hasn’t been able to get a delivery date for a valve needed for the process, he said. The city will have to work with a couple of different suppliers.
“The good news is we essentially have a full tank and we have all the water flow that we need,” he said.
The poly-pig is not impacting the city’s ability to fill the tank because it is lodged in a valve off to the side of the water flow, he said. But the pig has to be moved because it obstructs the T section, which is critical for maintenance processes, Perry said.
Until the city gets the supplies needed to retrieve the pig, workers will prepare the site for excavation.
The area that will need to be excavated to remove the device is along…
