When the mercury rose over 100 degrees Fahrenheit (39 degrees Celsius) in Seattle on Sunday, residents and visitors to the city’s waterfront, waterfront hotels and restaurants got a taste of the kind of damage that can come from a tropical storm.
It was a perfect storm for stormwater systems, which use salty water to control the flow of rain and snow.
“The stormwater system is really important for the people in Seattle because they can get water from their backyard,” said Ken Ehrlich, a water-management expert with the Puget Sound Regional Council.
He said the system helps protect against the damage caused by storms, such as flooding from hurricanes and tornadoes.
A recent report from the National Oceanic and Atmospheric Administration (NOAA) estimated the number of stormwater-related deaths in the U.S. in 2017 would be about 50,000.
“It’s important for everybody to have that safety net,” Ehrliche said.
The Washington State Department of Ecology and Natural Resources (WDOE) says stormwater runoff from storm drains, which are part of storm sewers, can carry contaminants such as sewage, lead and arsenic into the Pugets River, which flows into Lake Washington.
While stormwater drainage systems are not designed to remove the pollutants, they can reduce them.
But they have a price tag that can add up.
The average cost of storm-watered sewer system is $3.2 million per mile, according to the WDOE.
The agency said stormwater treatment plants also need to be built, so they can handle a heavy load of wastewater.
And many of the stormwater ponds need to replace, which means the system must be maintained.
That could take years.
The cost of a stormwater sewer replacement is usually around $2 million to $3 million per year, according the WDOE.
While the cost of the system could be cheaper, the cost will depend on how many stormwater drains are required, the size of the area where they’re needed and the maintenance of the systems.
The WDEE says the average cost for a storm-washed sewer replacement project in the Pugels is about $1.6 million per project.
“We’ve seen over the years that the costs for this kind of project have come down significantly,” Ederlich said.
In the case of storm water, the WDEO estimated a storm wash cost between $1 million and $2.3 million.
The system that protects you from rain and freezing rain, such a system, is built with storm sew, which is made up of concrete and concrete-lined walls.
Storm sewers can’t handle all the water that comes through the storm drains.
In some cases, they will simply not function.
And while storm sewings are generally used for storm water treatment, they’re also used for sewage, Ehrles said.
“You’re actually putting storm sew on top of sewage.”
The water that is treated can then be treated into drinking water.
The city’s stormwater project is built using storm sew and storm water from surrounding neighborhoods, and is expected to be completed in 2021.
But that’s just one example of how the system works.
Stormwater systems can be built in other places around the country, and the WSOE is also planning to expand its program.
Ehrle said a similar system could also help protect the environment.
“A lot of the things that are in the Seattle region, from sewage to storm water to sewage to water, are not that easily fixed,” he said.
But the storm water system will help protect you in other ways.
“They can do it by controlling the temperature of the water, but that’s the biggest thing,” Eerlich said of the WOWE.
“Because you can’t have a storm water discharge system that’s not able to regulate the temperature, you can get really good storm water out of that.”
