  • Key Largo Wastewater Treatment District Biosolids Digester Project Description
    Key Largo Wastewater Treatment District Biosolids Digester Project Description The project consists of the work as depicted in the Contract Documents, including the plans and specifications. This narrative description of the work is intended only to assist in the general understanding of the scope of work and is not intended to modify the scope of work as defined in the plans and specifications. Overview The work generally consists of demolition of several existing concrete structures, followed by construction of a pre-stressed concrete digester tank and associated equipment, piping and electrical elements. Following completion of construction and testing of the digester system, the WWTP staff will transfer biosolids from the existing tank currently being used as a digester, and the new digester will be placed into service. The work also includes cleaning of the existing digester tank and installation of equipment to convert the tank into its original intended use as Sequencing Batch Reactor #3. After the tank is cleaned, the Engineer will inspect the tank and determine if any repairs are needed. The Contractor will then install the SBR equipment provided by the District and install the influent piping as shown on the plans. The nutrient analyzers will also be installed. Following conversion of the tank to an SBR, the District staff will place the SBR into service and divert the flow from SBR #2 into SBR #3 for treatment. The Contractor will then clean SBR #2 for inspection by the Engineer and then proceed with the influent piping modifications and installation of the nutrient analyzers. When SBR #2 is completed, the District staff will transfer the flow from SBR #1 to SBR #2, allowing the Contractor to commence with the same scope of work on SBR #1.

    water Article Analysis of Greenhouse Gas Emissions in Centralized and Decentralized Water Reclamation with Resource Recovery Strategies in Leh Town, Ladakh, India, and Potential for Their Reduction in Context of the Water–Energy–Food Nexus Mounia Lahmouri, Jörg E. Drewes and Daphne Gondhalekar * Chair of Urban Water Systems Engineering, Department of Civil, Geo and Environmental Engineering, Technical University of Munich, 80333 München, Germany; [email protected] (M.L.); [email protected] (J.E.D.) * Correspondence: [email protected] Received: 2 February 2019; Accepted: 10 April 2019; Published: 29 April 2019 Abstract: With the constant increase of population and urbanization worldwide, stress on water, energy, and food resources is growing. Climate change constitutes a source of vulnerability, raising the importance of implementing actions to mitigate it. Within this, the water and wastewater sector represents an important source of greenhouse gas (GHG) emissions, during both the construction and operation phase. The scope of this study is to analyze the GHG emissions from the current and future water supply scheme, as well as to draw a comparison between possible water reclamation with resource recovery scenarios in the town Leh in India: a centralized scheme, a partly centralized combined with a decentralized scheme, and a household level approach. Precise values of emission factors, based on the IPCC Guidelines for National Greenhouse Gas Inventories, previous studies, and Ecoinvent database, have been adopted to quantify the different emissions. Potential sources of reduction of GHG emissions through sludge and biogas utilization have been identified and quantified to seize their ability to mitigate the carbon footprint of the water and wastewater sector.

  • NYS Design Standards for Wastewater Treatment Systems
    NEW YORK STATE DESIGN STANDARDS FOR INTERMEDIATE SIZED WASTEWATER TREATMENT SYSTEMS MARCH 5, 2014 New York State Department of Environmental Conservation Division of Water 625 Broadway Albany, New York 12233-3505 Andrew M. Cuomo, Governor Joe Martens, Commissioner Photos on cover courtesy of: Lenning, D., T. Banathy, D. Gustafson, B.J. Lesikar, S. Wecker, D. Wright. 2005. Technology Overview Module. in (D.L. Lindbo and N.E. Deal eds.) Model Decentralized Wastewater Practitioner Curriculum. National Decentralized Water Resources Capacity Development Project. North Carolina State University, Raleigh, NC. The technologies shown on the cover are from other States and may not conform to these Design Standards. In the case of any conflict between the apparent installation of a technology from any of the cover photos and the specifications in the figures, tables or text of these Design Standards, the Design Standards shall be used. Foreword The Clean Water Act (CWA) was enacted to restore and maintain the chemical, physical, and biological integrity of the nation’s surface waters. This was to be done by reducing direct pollutant discharges into waterways, financing municipal wastewater treatment facilities, developing technology necessary to eliminate the discharge of pollutants, and by managing polluted runoff. In New York State, Article 17 of the Environmental Conservation Law (ECL), “Water Pollution Control,” was enacted to protect and maintain both surface and groundwater resources. It authorized the creation of the State Pollutant Discharge Elimination System (SPDES) Program to protect New York's water resources. On-site Wastewater Treatment Systems (OWTS) may discharge to either surface water or groundwater. Pursuant to Article 17 Title 7 of the ECL all OWTSs, without the admixture of industrial or other waste, and with a groundwater discharge of 1,000 gallons per day or greater or a surface water discharge of any size, must be covered by a SPDES permit issued by the New York State Department of Environmental Conservation (NYSDEC).

Several scenarios and treatment trains exist with more or less decentralized treatment. These scenarios need to be evaluated with life cycle assessment to highlight the advantages and the drawbacks of each one of them. District is the perfect scale to evaluate these scenarios as it is the scale of implementation of real pilot project. However it was not so frequently done. The tool developed in a previous study allows us to evaluate the case study of Belvédère in France. This district is under construction, and even if no source-separation is yet foreseen, it will be a good example of what can be achieved in a future French pilot project.
