Showcase Green Projects
Big Sister Creek Wastewater Treatment Plant (WWTP) Energy Efficiency Improvement
The Division of Sewerage Management identified the need to
complete several initiatives to address electrical loads and modernize the monitoring/control capabilities of the treatment plant. The facility improvements
to be completed as part of the Big Sister Creek WWTP Energy Efficiency Improvement Project include:
- Upgrade of lighting and lighting control;
- Provisioning of additional dissolved oxygen control in the aeration basins;
- Implementation of an energy management system through development of a SCADA system (including a green roof for the SCADA building addition);
- Modification of the return activated sludge system operation; and
- Supplying variable speed control for the aerobic digester blowers.
The total estimated cost as documented in a NYSERDA approved energy efficiency study is $1.1 million with an estimated payback of 8.4 years. The total energy
savings implemented through an energy performance contract would be 866,305 kwh/year (approximately 12% of facility usage). This project will save money,
provide environmental benefits, and will promulgate green principles. It is estimated that construction for this project will commence in 2012.
This project was awarded a Green Innovation Grant Program award to assist in funding the implementation.
Aurora North Pumping Station Elimination
The Aurora North Pumping Station services the southeastern portion of Erie County Sewer District (ECSD) No. 4. Based on the results of an engineering study,
it was determined that the pumping station could be eliminated and the flows could be redirected to the interceptor sewers of ECSD No. 4 a few miles away.
Furthermore, a life cycle cost analysis determined that the construction of a gravity sewer was more cost effective than the long-term capital and operational
needs of this pumping station. There are numerous benefits to this project, one of which being electrical savings. Based upon recent billing history,
this represents close to 120,000 – 150,000 kWh annually. It is estimated that construction for this project will commence in 2012.
Numerous Small Division of Sewerage Management Projects
Throughout the facilities of the Erie County Sewer Districts, motors, compressors, lighting, and other electrical equipment are constantly being evaluated to determine if operational savings may be realized by replacement of equipment with more efficient models or through other means (for example, adding a variable frequency drive on a constant speed motor). The Division of Sewerage Management works with National Grid, NYSERDA, and other organizations to identify incentives to offset the capital costs associated with these improvements. As result, the Division’s assets have been renewed to continue meeting our mission to convey and treat wastewater, while doing so more cost effectively.

The Village of Blasdell sanitary sewer system, including its wastewater treatment plant (WWTP) was recently taken over by the Erie County Sewer District (ECSD)
No. 3 through a merger of sanitary sewer services. Based on the results of an engineering study, it was determined that the Blasdell WWTP could be eliminated
and the flows could be redirected to the interceptor sewers of the nearby ECSD No. 3 Southtowns Advanced Wastewater Treatment Facility (AWTF). The life cycle
cost analysis completed as part of this engineering study determined that this project was the preferred option to address the future wastewater treatment needs
for this area.
There are numerous benefits to this project, one of which being electrical savings. This project will eliminate the current function of the Electric Avenue
Pumping Station (PS), Blasdell Milestrip PS, Main WWTP PS, and Labelle PS, along with the Blasdell WWTP. All of these changes will be handled via a gravity
sewer. The small incremental increase in flows at the Southtowns AWTF will not cause an appreciable increase in electrical usage at the facility as several
of the major loads at the Southtowns plant are fixed. Therefore, this project will have a major positive impact on energy efficiency through the elimination
of several facilities and their associated electrical usage. Based upon recent billing history, this represents close to 400,000 kWh annually.
It is estimated that construction for this project will commence in 2012.
Village of Hamburg Pumping Station Elimination
The Village of Hamburg sanitary sewer system was recently taken over by the Erie County Sewer District (ECSD) No. 3 through a merger of sanitary sewer services.
Based on the results of an engineering study, it was determined that three pumping stations (Charlotte Pumping Station (PS), Sherburn PS, and McKinley PS) that
were transferred as part of the merger could be eliminated by gravity sewers. Furthermore, a life cycle cost analysis determined that the construction of the
necessary gravity sewers was more cost effective than the long-term capital and operational needs for these pumping stations. There are numerous benefits to
this project, one of which being electrical savings. Based upon recent billing history, this represents close to 15,000 kWh annually. It is estimated that
construction for this project will commence in 2012.
