Lake Remediation in The Hudson Valley NY

Hillside Lake is a 26-acre impaired lake surrounded by a residential community of about 500 located in East Fishkill, NY. It suffers from a combination of stormwater runoff sedimentation and the drainage of unwanted nutrients into the lake causing degradation of water quality over time.
These problems have compromised groundwater significantly.  Recent well reports from homes near the lake show elevated levels of coliform and other hazardous pollutants.
The lake that was once the life force of a community is now shallow and unusable, covered with algae and other unwanted plant blooms and has caused harm to the local ecosystem.
The residents depend upon aquifer-based resources for their drinking water.  As goes the lake, so goes the water source. Preservation of water quality is the key issue to the area’s sustainability.

The Town was recently awarded a New York State Department of Environmental Conservation
Water Quality Improvement Grant.
A muti-faceted plan has been developed, approved and ready for construction Summer 2017

The plan includes:

  • Hydro raking of plants and vegetation in the lake
  • Construction of a gravel filter wetland to treat stormwater runoff
  • Floating islands throughout the lake that will provide ongoing “in-lake treatment” and aeration,
  • Re-circulation of lake water back through the wetland filter from critical points in the lake
  • Introduction of a unique Phosphorus media absorbent material

Renewage Stormwater Design awarded Green Invovation Grant for the revitalization of downtown Poughkeepsie NY


The project engages three forms of infrastructure renewal in
the City’s densest and most deteriorated area:

1) Improvements to public parking: The project seeks to improve the pavement
and drainage of two key public parking lots, eliminating the impacts of flooding
and poor storm water management during strong weather events,

2) Improvements to storm water management: Rerouting focused and
deteriorating storm drains by dispersing storm water into ground water sources precludes the maintenance of catch basins and similar outdated storm water management technologies,

3) Mitigation of Inflow and Infiltration in Waste Water Systems: Not only does the project limit I & I flows from these currently hard, tarmac surfaces, but it also reduces the vulnerability of combined sewers.

Support the City’s goal of pollutant load reductions
• Enhancement of the neighborhood surrounding the project utilizing
aesthetic “green” practices and materials to improve the quality of life
in the downtown core
• Reduction of pollutants entering the Hudson River Watershed
• Mitigation of Inflow and Infiltration (I&I) into the City’s Sewers and
Treatment Systems
• Utilization of trees and plantings to reduce “heat island” in accordance
with US Green Building Code
• Develop a demonstration project that can be replicated elsewhere in
the City, County and State to demonstrate how these green practices
can be utilized

2 Renewage Green Infrastructure projects awarded grant funding in NY

Today Governor Andrew Cuomo announced grant awards for economic development and other community improvement projects:  These 2 Renewage projects will be funded and able to go forward in partnership with our municipal partners:
The Town of East Fishkill will install a recirculating gravel wetland adjacent to Hillside Lake. The wetland will reduce the amount of sediment and nutrients entering the lake.   Award: $647,500.
The Village of Wappingers Falls will complete a comprehensive study of point and non-point source pollution into the Wappinger Creek Watershed. The plan will analyze Wappinger Creek from its headwaters to Wappinger Lake in an effort to identify key contributors to pollutant-loading, which is deteriorating water quality and flood storage. The plan will set implementation time frames, establish guidelines, and identify practices, including artificial wetlands and green infrastructure.   Award: $287,500.…/…/atoms/files/REDCAwardsBooklet2015.pdf

Renewage is currently working on several projects in New York State and around the world

Renwage works on private, commercial and public projects that utilize Low Impact Design technologies and Best Management Practices.  The scale of our projects ranges from private homes and small infill sites to larger municipal commercial and industrial Green Infrastructure systems.
Renewage engages all stakeholders, funding sources and regulatory agencies.
Renewage is able to call upon a diverse network of innovate and experienced leaders in the field to study, design and implement these projects.


Philmont, Columbia County NY
Renewage selected by Village of Philmont NY to study and propose Low Impact Design BMP Stormwater Treatment to revitalize Summit Reservoir

Renewage chosen by The Village of Philmont Beautification Committee to develop a plan for Summit Reservoir in the The Village as part of a BOA (Brownfield Opportunity Area) Grant from the Governor of NY. Renewage will asses issues adversely impacting water quality and recommend BMP practices that will help reduce sediment and capture the attached phosphorus and other nutrients (nitrogen, coliform) to begin the process of water quality improvement in the lake.

Sufflolk County New York
Renewage’s PBR Wastewater Treatment System (A unique hybrid MBBR & Wetland) Chosen as a demonstration to be built at The Nature Conservancy’s Upland Farm Headquarters at Cold Spring Harbor NY

Renewage chosen by The Nature Conservancy in Suffolk County NY – to demonstrate larger “cluster” treatment system at Uplands Farm Sanctuary at Cold Spring Harbor NY. The PBR ecological wastewater treatment system will reduce Nitrogen and be the first “hybrid” MBBR & Wetland treatment system of its type in New York!

Water Quality Improvement

The Village of Wappingers Falls in Dutchess County NY,  has been concerned for many years about the deterioration of its lake, the lifeblood of the community, and source of its clean drinking water.  The lake, which drains to the Hudson Estuary has gradually filled with sediment and adverse “loading” from nearby development upstream.  Stormwater runoff was causing flooding during major storm events

Renewage has developed a comprehensive water management plan for the entire 220 square mile watershed and built the first in a proposed series of BMP gravel filter, stormwater wetland treatment installations at an infill site in The Village of Wappingers Falls.  PROJECT VIDEO:

The storm-water wetland is the first of it’s kind to be permitted and built in NY.  It will not only capture and treat up to 95% of the sediment passing through before it reaches the lake, but will also reduce phosphorus nitrogen and other pollutants flowing into the lake. The storm-water wetland will limit flooding to nearby housing during major storms and begin the process of water quality remediation in the watershed.  The project was awarded a prestigious Green Innovation Grant from NYS EFC

Gravel Filter Stormwater Wetland in operation

Hillside Lake,
East Fishkill, Dutchess County NY

Hilside is a 26-acre lake, and home to 500 families in East Fishkill NY
A combination of the man-madEFK_HillsideLake-29e nature of the lake, heavy soils in the drainage area, nutrient loading from septic systems and increased storm water run-off have caused degradation of water quality over time.   The lake is currently filling with
sediment and overgrown with algae and weeds.  It is listed by NY State DEC as an impaired waterbody.

Renewage was selected to develop a long range strategy and treatment plan.  Storm water management was identified as a first priority.  Renewage has developed plans to construct two ecological gravel storm water treatments along the lake’s perimeter.  The ultimate goal is to reverse the endemic deterioration of the lake’s water quality and eco-system.  NYSDEC and other permitting agencies support this approach.   Final design and implementation will begin shortly.
