Bid Description:
The Vermont Department of Environmental Conservation is requesting proposals to employ green stormwater infrastructure (GSI) to reduce polluted runoff and high stormflows from developed lands that drain into combined sewer systems (CSS) and contribute to combined sewer overflows (CSOs). CSS separation is expensive and many CSO Long Term Control Plans (LTCP) could utilize GSI to infiltrate stormwater runoff before it enters CSSs, which can minimize risk of CSOs in a cost-effective manner. In addition, CSS separation projects often create new untreated stormwater discharges. Implementation of GSI is a priority in the Clean Water State Revolving Fund (CWSRF) and Clean Water Initiative Program (CWIP) and the practice is known to be cost effective and sustainable if implemented successfully.
