PHILADELPHIA — This city has proposed tackling its combined-sewer overflow problems with a $1.6 billion, 20-year plan that would use rain gardens, green roofs, thousands of additional trees, rain-harvesting barrels and porous pavement, The Philadelphia Inquirer reported September 27.
Environmental experts and federal regulators are reviewing the 3,369-page plan put forth by the Philadelphia Water Department.
The green capture plan is being hailed as one of the most ambitious ideas to reduce combined sewer overflows and increase “green” living of a major metropolitan area. According to the plan, runoff is reduced, diverted or filtered by layers of soil and plant root systems. The Inquirer reported, “Some areas would temporarily store runoff until the stress of the storm on the combined sewer system is reduced and the water can then be treated in the sewer treatment plants.”
