Wastewater Management

B&L’s knowledgeable professionals are available to help with every stage of the wastewater treatment process, from initial planning to start-up assistance and grantsmanship to public communications. As part of our comprehensive services, we provide assistance with asset management, process and facilities design, permitting and environmental quality reviews.  Our engineers are versed in the most current regulatory requirements, as well as the latest technological innovations for solving complicated wastewater issues.

 

Demands for regulatory compliance together with aging infrastructures and operational cost increases have driven local municipalities and private organizations to look for alternatives to building. Retrofitting and upgrading current facilities are proven ways to improve efficiency and save costs, and the B&L team can help you assess the needs of your wastewater system.

Weedsport

Weedsport Wastewater Treatment Plant Improvements and Asset Management Program

  • renovated control building
  • Converted treatment tank to SBR
  • Aerobic digesters
  • Control building with post-aeration blower
  • new blower building

The Village of Weedsport owns and operates a sanitary sewer system, portions of which date back to the early 1900s, and a 0.30 MGD activated sludge wastewater treatment plant (WWTP) constructed in the 1960s. In addition to the age of the facility, the WWTP’s average daily flow was at nearly 100 percent of the plant’s capacity, and peak wet weather flows are in excess of the plant’s influent pumping capacity, at times necessitating emergency bypass pumping operations by the WWTP operators.  B&L completed a combined collection system I/I Study and WWTP Facilities Plan and assisted the Village in securing American Recovery and Reinvestment Act (ARRA) funding for the project, including approximately $3.0M in principal forgiveness, of which approximately $400,000 is “Green Project Reserve” for energy efficiency measures incorporated into the WWTP improvements design.  An asset management program was developed following the plant upgrades.

 

 

 

Caughdenoy Sewer District Extension No. 1

Caughdenoy

Caughdenoy Sewer District No. 1

  • Diffuser pressure monitoring and D.O. level
  • Digester fine bubble aeration retrofit
  • New digester covers
  • New pump station at old sand filter plant
  • SBR retrievable fine bubble aeration retrofit

The Caughdenoy Sewer District, serving approximately 92 households and formed in 1985, utilizes a gravity collection system and 30,000 gallon per day sand filter treatment plant with surface water discharge to treat the district’s sanitary wastewater. The sand filter, in recent years, has suffered seasonal break-out of partially treated wastewater, necessitating improvements to avoid a NYSDEC Consent Order. 

 

The $6.2 million project is a “win-win” for all Town sewer district residents. It will eliminate environmental impacts to the Oneida River through elimination of the sand filter WWTP discharge and 160 on-site treatment systems fronting the river, and at the same time add much needed flows and loads to the SBR plant along with additional users to reduce operation and maintenance costs. Further, energy efficiency improvements will effectively reduce O&M costs and annual costs to new and existing sewer district customers.

  • New duplex submersible pump station and force main
  • Formation of Caughdenoy Sewer District Extension No. 1 to facilitate connection of approximately 160 units to the new force main via individual grinder pumps
  • Construction of a new emergency generator at the Main Pumping Station
  • Construction of a new 6-inch force main to replace an undersized 4-inch force main
  • Energy efficiency improvements to the FBSD SBR plant, including fine bubble aeration retrofit, digester covers, variable speed drives on blowers, and dissolved oxygen based blower controls.

 

 



Monticello Wastewater Treatment Plant and Collection System Improvements

The Village of Monticello’s sewer system was built more than 50 years ago and according to previous sewer system evaluation surveys, much of the existing collection system is experiencing inflow and infiltration through damaged pipes. Many of the pump stations in the system are at the end of their useful life and require improvements. 

 

B&L assisted with the funding application and the project received $14.4 million grant and low-interest funding package from the USDA-RD to potentially finance the project, the largest ever award committed in New York by the USDA-RD. Features of the project currently in design include:

 

Collection system:

  • Replace East Broadway and Racetrack Pump Station pumps
  • Replace and upgrade Route 42 Pump Station
  • Construct grit removal building at Race Track Pump Station
  • Install cured-in-place liner system along a portion of West Broadway
  • Replace 500-foot section of Park Ave. and Broadway 
  • Replace 25 identified manholes experiencing infiltration

 

Treatment Plant:

  • Retrofit existing two oxidation ditches and stormwater retention basin into three sequencing batch reactor (SBR) tanks
  • Retrofit one of the existing clarifiers as an aerobic digester
  • Replace and upgrade the existing sand filters with four disc filters
  • Replace the existing aerated grit chamber with a vortex grit separator
  • Construct addition to the headworks building for new grit system
  • Construct addition to the sludge processing building
  • Replace progressive cavity sludge handling pumps
  • Construct reed beds for on-site sludge processing
  • Energy efficiency improvements to the filter, headworks and sludge buildings

Pattonwood Pump Station Improvements

Pattonwood Pump Station Improvements

Pattonwood Pump Station Improvements

  • Energy consumption graphic
  • New control and power panels
  • New suction-lift centrifugal pumps
  • Pump suction and discharge piping

The pump station was originally constructed in 1976 with a wet well/dry well configuration.  The steel dry well is located partially beneath the pump control building, which itself sits directly above the wet well.  The existing pumps required confined space entry and were operating inefficiently at lower design speeds. B&L provided design, bidding, and construction administration/observation services for:

  • Retrofitting the pump station with two new above grade, 25-Hp vacuum-prime suction lift centrifugal pumps and a PLC-based variable speed drive control system
  • Installation of two mechanical mixers in the wet well
  • A bypass pump piping system
  • New heating and ventilating systems
  • New portable generator with automatic transfer switch and quick connect 
  • New magnetic flow meters
  • General site improvements and refurbishment/reuse of the existing pump control building

The improvements will result in approximately $7,500 savings in annual electric costs resulting in an equivalent savings of $150,000 over the next 20 years as shown in the above power consumption chart.

 


 

 

Liberty Wastewater Treatment Plant FlexTech Analysis and Facilities Plan

Barton & Loguidice prepared a facilities plan and energy analysis of improvements to the Swan Lake WWTP in the Town of Liberty. The facilities plan evaluated treatment process alternatives based on their energy efficiency and life-cycle cost to maintain the current permitted treatment capacity. B&L then assisted with completing a preliminary engineering report and pre-application to USDA Rural Development. 

 

This $4.8 million project, scheduled for completion in 2013, includes:

 

  • Expanding the influent channel, install new influent flow meter and manual bar screen
  • Replacement of the existing comminutor with influent grinder
  • Replacement of the existing aerated grit chamber with vortex grit removal system
  • Replacement of the existing influent pumps and controls
  • Retrofitting the existing oxidation ditches with SBRs
  • Replacement of the existing aeration blowers and controls
  • Retrofitting existing sludge holding tanks as effluent equalization basin 
  • Replacement of the existing closed vessel UV reactors with open channel UV disinfection equipment
  • Replacement of the existing mechanical post aeration system with energy efficient gravity cascade post aeration 
  • Retrofitting existing secondary clarifiers as aerobic sludge digesters
  • Rehabilitation of the existing sludge drying beds
  • Installation of a new emergency generator and ATS system
  • Installation of a new SCADA system
