The E.P.A. will also aim to reduce the sewer overflow from the city drains.
She steeped herself in environmental arcana, phrases like "combined sewer overflow" and "mercury deposition" tripping off her lips.
The plan's priorities include nitrogen reduction, habitat restoration, storm water control, sewer overflow abatement and sediment remediation.
To avoid wastewater backing up into homes or streets, combined sewer overflow outlets allow untreated water to bypass the plants and flow directly into the waterways.
The city will also redirect to a treatment plant about 120 million of the roughly 370 million gallons of sewer overflow dumped in the canal every year.
When sewer and storm water carried by the same pipes overwhelm the city's treatment plants during storms, the sewer system discharges a mix of wastewater and storm water — called a combined sewer overflow – into waterways from 423 outfall locations.
Excessive dredging, millions of gallons of waste and untreated storm water, sewer overflow, wind-blown trash, soot and chemicals from transportation, and large-scale development are the real causes of pollution — not just the occasional ritual offerings of devout Hindus.
But our sewers also collect rainwater, which mixes with raw sewage (called "combined sewer overflow," or CSO) and is dumped into nearby rivers and creeks through hundreds of pipes to avoid inundating the treatment plants.
These include upgrades of wastewater treatment plants; technology that removes nitrogen from wastewater; combined sewer overflow facilities; remediation of landfills; and restoration of ecosystems at 13 sites, including salt marshes and shorelines.
This is an aggressive but critical goal among our other plans to reduce the harmful effects of stormwater runoff and mitigate the effects of combined sewer overflow loading into the sound.
That's obviously not a selling point for real estate, and as part of its redevelopment efforts the city had already announced a $175 million plan to limit the sewer overflow.
