As described in https://data.cityofchicago.org/stories/s/sihu-d8va, the function of this dataset was replaced by https://data.cityofchicago.org/d/4tzt-ir6h. This dataset is historical-only. Concentrations of the SARS-CoV-2 virus (the COVID-19 virus) gene in the Chicago sewer system, as measured at eight sewershed sites. These sites represent catchment areas that describe wastewater from 319,700 Chicagoans as of January 2023. Because SARS-CoV-2 is shed in human feces, this method can be used to estimate changes in COVID-19 at different times and locations across Chicago. While the data in this dataset do not indicate how many people were infected with SARS-CoV-2, differences in the the normalized_n1 indicate whether the proportion of individuals at the site who are shedding that virus has changed.

Area defined by Article R2224-10 of the General Code of Local and Regional Authorities (transposition of the European Directive of 21 May 1991).Agglomeration is an area in which the population or economic activities are sufficiently concentrated so that domestic waste water can be collected and transported to a single sewage treatment system. competent.The map of the agglomeration is stopped by the prefect.The agglomerations are codified by a SANDRE code.

The GIS dataset represents the Assigned Sewer Service Areas associated with Wastewater Treatment Facilities that discharge to surface and ground water established pursuant to N.J.A.C. 7:15-4.4. Assigned Sewer Service Areas are defined as the eligible sewer service area from which sewage flows are conveyed to a specific wastewater treatment facility (WWTF). For the purposes of the wastewater treatment plant capacity analysis which is a required component of areawide Wastewater Management Plans, the Assigned Sewer Service Area is the area reasonably expected to generate sewage that will be conveyed to the WWTF or to an industrial treatment works that accepts sewage generated from areas other than the industrial facility according to N.J.A.C. 7:15-1.5.The original GIS dataset and map was approved by the Somerset County Board of Chosen Freeholders as the first phase in the development of the countywide wastewater management plan and authorized their submission to NJDEP for consideration as an amendment to the Upper Raritan, Northeast and Lower Raritan/Middlesex County Water Quality Management Plans (WQMP) on February 28, 2012 via Resolution No. R12-015. On January 24, 2013, NJDEP adopted the dataset and map as an amendment to the Upper Raritan and Northeast WQMP, and on March 5, 2013, NJDEP adopted the dataset and map as an amendment to the Lower Raritan/Middlesex County WQMP. On November 4, 2019 the NJDEP adopted the Montgomery Township and Rocky Hill Borough Component of the Somerset County WMP that includes the dataset and map, Wastewater Treatment Plant Capacity Analysis and Strategies to Mitigate Wastewater Treatment Capacity Deficiencies pertaining to Assigned Sewer Service Areas within these two (2) municipalities. Since this time, the countywide dataset and map have been updated to reflect the terminology changes contained in the WQMP Rules (N.J.A.C.7:15). For example, "Future Wastewater Service Areas Discharging to Surface Water and Ground Water are now referred to as "Assigned Sewer Service Areas". The dataset and map adopted by NJDEP in 2013 was further updated to reflect the site-specific revisions and amendments that were adopted by the NJDEP since that time. The dataset and map also incorporates wastewater flow transfers that have taken place in Montgomery Township and that were approved at the local level in Warren Township and Watchung Borough. The dataset and map also reflect the anticipated discontinuation/closure of certain existing permitted category GW and T1 WWTFs for which sewer service areas have been assigned and that are also located within the Assigned Sewer Service Areas of WWTFs that discharge to surface water. Redevelopment and/or expansion of the existing development at these sites is anticipated in the future, at which time the on-site groundwater discharge facilities will be connected to the WWTF systems that discharge to surface water. It is important to note that this dataset and map do not include any expansions of the Assigned Sewer Service Areas adopted by NJDEP in 2013 other than the NJDEP-adopted site specific amendments and revisions that took place since 2013.Areas within Somerset County are included in the following Water Quality Management Planning (WQMP) Areas: 1) Upper Raritan Areawide WQMP Area, 2) Northeast WQMP Area and 3) the Lower Raritan/Middlesex County WQMP Area. As noted in N.J.S.A. 7:15-2.3, “Areawide Water Quality Management Plans (WQMP) identify and address selected water quality and wastewater management issues for a particular jurisdictional area, including strategies to address both point and nonpoint source pollution. The areawide WQMP is the basis by which the NJDEP and the designated planning agencies (DPAs) conduct selected water quality management planning activities for a particular area of the State. The aforementioned WQMP areas represent three (3) of the twelve (12) areawide WQMPs which together cover the entire State of New Jersey that were established pursuant to Sections 208 and 303 of the Clean Water Act. Areawide WQMP include the WMPs, TMDLs, and other water quality improvement and wastewater related plans as determined appropriate by the DPA and the NJDEP”. The dataset and map are components of the Somerset County Wastewater Management Plan (WMP). The Somerset County WMP constitutes a portion of the Upper Raritan, Northeast and Lower Raritan/Middlesex County Water Quality Management Plans (WQMP).

This data was created through the modification of an existing sewer service dataset from the CT Office of Policy and Management (OPM), in addition to sewer data from the Southeastern Connecticut Council Of Government (SCCOG) and the Town of Stonington. It also includes data from the Sewer Service Area 2018 file in areas where the OPM dataset was not as current. The OPM data was modified by reducing the extensive categories which represent all areas containing sewers to a "Connected" classification.SCCOG Data: Data was clipped to individual municipal boundaries for all 21 municipalities with sewer information within the SCCOG. The "Existing" category from attribute table was extracted via selection to create the "Connected" areas for 19/21 municipalities. The Town of Stonington data was merged with the SCCOG data as both had areas which were not included in the other. The North Stonington data was combined with SSA 2018 data to get the most accurate representation for that town. OPM Data: Data was modified to isolate the undefined and fragmented categories, (QA- using municipal websites, PDF maps and local contacts for verification where available) then Clipped to municipal boundaries. All the areas that are connected to sewers were Dissolved, only maintaining the key fields listed and described below. The datasets were combined using the Merge tool to get all the connected sewer service areas in the state.Description of Fields:TOWN- Represents all the municipalities with the state of CTs boundaries. CNTY_NAME- Represents the eight (8) county names to which each municipality belongs to.

SEWERS- This field has two classes "Existing" and "No Sewer" and this identifies if a municipality has sewers existing within its boundary or not. SEWER-STATUS- The Sewer Status field represents the areas within in each municipality that are "Connected" to sewers.TREATMENTFACILITY- This field represents the sewer service treatment facility (endpoint) that processes the waste for each municipality. For municipalities without sewers, “Not Applicable” is the designated value. PASSTHROUGH- This field identifies if the wastewater passes through other municipalities on the way to the treatment facility (endpoint) as denoted by a "Yes" or "No" value. Feature class is symbolized on the Sewer Status field to show the “Connected” (green).

This Event Duration Monitoring (EDM) dataset relates to the performance of storm overflows in England. Data are provided by Water and Sewerage Companies (WaSCs) to the Environment Agency each year as part of their regulatory Annual Return, to fulfil their permitted conditions to discharge from these storm overflows under the Environmental Permitting Regulations.

Data files are provided by year (2024, 2023, 2022, 2021 & 2020) and include a sheet for each of the 10 WaSCs with storm overflows in England. Each WaSC sheet shows how often and how long each monitored storm overflow discharged during that year. From 2021 onwards the dataset also includes reasons why event duration monitors (EDM) may have provided information for <90% of the relevant return period, and why an overflow may have high spill counts in that period. These data reflect the best available information held by the WaSC at time of submission.

The data file for each year also contains key summary data tables. These include: number of storm overflows with EDM, number of storm overflows returning spill counts, average spill duration and average spill count for each WaSC. A dataset README guide is also provided which provides further information to help use and understand the data.

A sixth data file contains the annual key summary data from respective years plus a table showing long-term trends from 2016-2024.

This dataset supports the Biomarker: Vector-Borne Viruses page on the Tempe Wastewater BioIntel Program site.Wastewater collection areas are comprised of merged sewage drainage basins that flow to a shared testing location for the Tempe Wastewater BioIntel Program. The wastewater collection areas represent a geographic area for which virus activity is tested. People infected with a virus excrete the virus in their feces in a process known as “shedding”. The municipal wastewater treatment system (sewage system) collects and aggregates these bathroom contributions across communities. The process begins at sampling site where, over a period of 24 hours, a wastewater sample is collected along the sewer line. After the sample is acquired, it is immediately transferred to a lab where scientists prepare the sample. The laboratory analysis seeks to determine if there is a signal (or detectable presence) of the biomarker in the wastewater. Please see the Tempe Wastewater BioIntel Program site for more information on the wastewater testing process at https://wastewater.tempe.gov/. About the data: These data illustrate a trend of the signal of the weekly average or weekly results of Tempe wastewater biomarker groups. The dashboard and collection area map do not depict the number of individuals infected. Each collection area includes at least one sampling location, which collects wastewater from across the collection area. It does not reflect the specific location where the deposit occurs. While testing can successfully quantify the results, research has not yet determined the relationship between these values and the number of people who are contributing to the signals. The influence of this data on community health decisions in the future is unknown. Data collection is being used to depict overall weekly trends and should not be interpreted without a holistic assessment of public health data. The purpose of this weekly data is to support research as well as to identify overall trends of the genome copies in each liter of wastewater per collection area. We share this information with the public with the disclaimer that only the future can tell how much “diagnostic value” we can and should attribute to the numeric measurements we obtain from the sewer. However, we know what we measure is real and we share that info with our community. Data are shared as the testing results become available. As results may not be released at the same time, testing results for each area may not yet be seen for a given day or week. The dashboard presents the weekly averages. Data are collected from 2-7 days per week. For Collection Area 1, Tempe's wastewater co-mingles with wastewater from a regional sewage line. Tempe's sewage makes up most of Collection Area 1 samples. For Collection Area 3, Tempe's wastewater co-mingles with wastewater from a regional sewage line. For analysis and reporting, Tempe’s wastewater is separated from regional sewage. Week start date represents the starting date of the testing week, which starts on Mondays and ends on Sundays.

A sewer lateral is the underground pipe that connects a residence or business to the sewer line.Sewer Lateral connections were originally recorded as points on the property line, but in 2017 the points were changed to lines instead to accommodate new software. The lateral line begins at the same location on the property line where the existing point was, and then it is drawn straight out to the nearest main. The lines were automatically drawn by the computer, so the actual path of the lateral line from the property line to the sewer main may differ. These will be manually corrected over time.Data are updated by city staff as needed, and automatically copied to the Open Data Portal. The "Last Updated" date shown on our Open Data Portal refers to the last time the data schema was modified in the portal, or any changes were made to this description. We update our data through automated scripts which does not trigger the "last updated" date to change.Note: Attributes represent each field in a dataset, and some fields will contain information such as ID numbers. As a result some visualizations on the tabs on our Open Data page will not be relevant.

Subsurface sewage disposal systems (SSDS) consist of a house sewer, a septic tank followed by a leaching system, any necessary pumps and siphons, and a groundwater control system upon which the operation of the leaching system depends. This interpretation focuses mainly on the septic tank leaching field and groundwater control system Soil Potential Ratings Soil potential ratings indicate the relative quality of a soil for a particular use compared to othersoils in a given area, in this case the State of Connecticut.The rating criteria were developed by a committee of State and local sanitarians, engineers, and installers. The soils data was provided by the USDA Natural Resources Conservation Service (NRCS), and the performance and site conditions for a typical system were defined. This information provided a standard against which various combinations of properties of soils within Connecticut could be compared.The engineering and installation practices used to overcome various soil limitations were listed, and their costs estimated. This information was used to identify limitations and costs associated with installing an SSDS on each soil in Connecticut. Soils with no or minor limitations for the installation of an SSDS were rated the highest. Conversely, soils requiring extensive site modification and design were rated the lowest. The ease of system installation, and therefore cost, formed the basis of the rating scheme.Rating ClassesThe rating class definitions refer to installation of an SSDS that meets State and local health code regulations. Soils with high potential have characteristics that meet the performance standard. A typical system can be installed at a cost of "x", which represents the going rate for installing an SSDS. The actual value of x varies depending upon many factors unrelated to soil properties. The cost of installing a leaching field is expressed as a multiple of x and called the cost factor. For example, a cost factor of 3x to and 3.5x means that the estimated cost of installing a leaching field in the particular soil ranges from 3 to 3.5 times more than that of installing a field in a soil with high potential. The cost factors provide relative estimates of the costs of installing an SSDS.The soil potential ratings and associated cost factors, assuming a typical system, are defined below.High Potential - These soils have the best combination of characteristics or have limitations that can be easily overcome using standard installation practices. The cost factor is 1x to 2.0x.Medium Potential - These soils have significant limitations, such as low percolation rate, that generally can be overcome using commonly applied designs. The cost factor ranges from 2.0x to 2.5x.Low Potential - These soils have one or more limitations, such as low percolation rate and depth to seasonal high water table, that require extensive design and site preparation to overcome. The cost factor ranges from 2.5x to 3.5x.Very Low Potential - These soils have major soil limitations, such as depth to bedrock, that require extensive design and site preparation to overcome. A permit for an SSDS may not be issued unless the naturally occurring soils meet the minimal requirements outlined in the State health code. It is unlikely that these soils can be improved sufficiently to meet State health code regulations. The cost factor ranges from 4.25x to 6.0x.Extremely Low Potential - These soils have multiple major limitations, such as flooding and depth to seasonal high water table, which are extremely difficult to overcome. A permit for an SSDS may not be issued unless the naturally occurring soils meet the minimal requirements outlined in the State health code. It is unlikely that these soils can be improved sufficiently to meet State health code regulations. Not Rated - Areas labeled Not Rated have soil characteristics that show extreme variability from one location to another. The work needed to overcome adverse soil properties cannot be estimated. These areas commonly are urban land complexes or miscellaneous areas. An on-site investigation is required to determine soil conditions at the site.This data set is a digital soil survey and generally is the mostdetailed level of soil geographic data developed by the NationalCooperative Soil Survey. The information was prepared by digitizingmaps, by compiling information onto a planimetric correct baseand digitizing, or by revising digitized maps using remotelysensed and other information.This data set consists of georeferenced digital map data andcomputerized attribute data. The map data are in a soil survey areaextent format and include a detailed, field verified inventoryof soils and miscellaneous areas that normally occur in a repeatablepattern on the landscape and that can be cartographically shown atthe scale mapped. The soil map units are linked to attributes in theNational Soil Information System relational database, which givesthe proportionate extent of the component soils and their properties.

Wastewater collection areas are comprised of merged sewage drainage basins that flow to a shared testing location for the COVID-19 wastewater study. The collection area polygons are published with related wastewater testing data, which are provided by scientists from Arizona State University's Biodesign Institute.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19. People infected with SARS-CoV-2 excrete the virus in their feces in a process known as “shedding”. The municipal wastewater treatment system (sewage system) collects and aggregates these bathroom contributions across communities. Tempe wastewater samples are collected downstream of a community and the samples are brought to the ASU lab to analyze for the virus. Analysis is based on the genetic material inside the virus. About the data:These data illustrate a trend of the signal of the weekly average of COVID-19 genome copies per liter of wastewater in Tempe's sewage. The dashboard and collection area map do not depict the number of individuals infected. Each collection area includes at least one sampling location, which collects wastewater from across the collection area. It does not reflect the specific location where the deposit occurs.While testing can successfully quantify the results, research has not yet determined the relationship between these genome values and the number of people who are positive for COVID-19 in the community.The quantity of RNA detected in sewage is real; the interpretation of that signal and its implication for public health is ongoing research. Currently, there is not a baseline for determining a strong or weak signal.The shedding rate and shedding duration for individuals, both symptomatic and asymptomatic, is still unknown.Data are shared as the testing results become available. As results may not be released at the same time, testing results for each area may not yet be seen for a given day or week. The dashboard presents the weekly averages. Data are collected from 2-7 days per week. The quantifiable level of 5,000 copies per liter is the lowest amount measurable with current testing. Results that are below the quantifiable level of 5,000 copies per liter do not suggest the absence of the virus in the collection area. It is possible to have results below the quantifiable level of 5,000 on one day/week and then have a greater signal on a subsequent day/week.For Collection Area 1, Tempe's wastewater co-mingles with wastewater from a regional sewage line. Tempe's sewage makes up the majority of Collection Area 1 samples. After the collection period of April 7-24, 2020, Collection Area 1 samples include only Tempe wastewater.For Collection Area 3, Tempe's wastewater co-mingles with wastewater from a regional sewage line. For analysis and reporting, Tempe’s wastewater is separated from regional sewage.

This pipe feature class represents current wastewater information of the mainline sewer in the City of Los Angeles. The Mapping and Land Records Division of the Bureau of Engineering, Department of Public Works provides the most rigorous geographic information of the storm drain system using a geometric network model, to ensure that its storm drains reflect current ground conditions. The conduits and inlets represent the storm drain infrastructure in the City of Los Angeles. Storm drain information is available on NavigateLA, a website hosted by the Bureau of Engineering, Department of Public Works.Associated information about the wastewater Pipe is entered into attributes. Principal attributes include:PIPE_SUBTYPE: pipe subtype is the principal field that describes various types of lines as either Airline, Force Main, Gravity, Siphon, or Special Lateral.For a complete list of attribute values, please refer to (TBA Wastewater data dictionary). Wastewater pipe lines layer was created in geographical information systems (GIS) software to display the location of sewer pipes. The pipe lines layer is a feature class in the LACityWastewaterData.gdb Geodatabase dataset. The layer consists of spatial data as a line feature class and attribute data for the features. The lines are entered manually based on wastewater sewer maps and BOE standard plans, and information about the lines is entered into attributes. The pipe lines are the main sewers constructed within the public right-of-way in the City of Los Angeles. The ends of line segments, of the pipe lines data, are coincident with the wastewater connectivity nodes, cleanout nodes, non-structures, and physical structures points data. Refer to those layers for more information. The wastewater pipe lines are inherited from a sewer spatial database originally created by the City's Wastewater program. The database was known as SIMMS, Sewer Inventory and Maintenance Management System. For the historical information of the wastewater pipe lines layer, refer to the metadata nested under the sections Data Quality Information, Lineage, Process Step section. Pipe information should only be added to the Wastewater Pipes layer if documentation exists, such as a wastewater map approved by the City Engineer. Sewers plans and specifications proposed under private development are reviewed and approved by Bureau of Engineering. The Department of Public Works, Bureau of Engineering's, Brown Book (current as of 2010) outlines standard specifications for public works construction. For more information on sewer materials and structures, look at the Bureau of Engineering Manual, Part F, Sewer Design, F 400 Sewer Materials and Structures section, and a copy can be viewed at http://eng.lacity.org/techdocs/sewer-ma/f400.pdf.List of Fields:STREET: This is the street name and street suffix on which the pipe is located.PIPE_LABEL: This attribute identifies the arc segment between two nodes, which represents the pipe segment. There could be any number of pipes between the same two maintenance holes and at least one. If there is more than one pipe between the same two maintenance holes, then a value other than 'A' is assigned to each pipe, such as the value 'B', 'C', and so on consecutively. Also, when a new pipe is constructed, some old pipes are not removed from the ground and the new pipe is added around the existing pipe. In this case, if the original pipe was assigned an 'A', the new pipe is assigned a 'B'.C_UP_INV: This is the calculated pipe upstream invert elevation value.PIPE_MAT: The value signifies the various materials that define LA City's sewer system. Values: • TCP - Terra Cotta pipe. • CMP - Corrugated metal pipe. • RCP - Reinforced concrete pipe.

A sewer pipe line has a value for the UP_STRUCT and DN_STRUCT fields. This point is the downstream structure that may be a maintenance hole, pump station, junction, etc. Each of these structures is assigned an identifying number that corresponds to a Sewer Wye data record. The 8 digit value is based on an S-Map index map using a standardized numbering scheme. The S-Map is divided into 16 grids, each numbered sequentially from west to east and north to south. The first three digits represent the S-Map number, the following two digits represent the grid number, and the last three digits represent the structure number within the grid. This field also relates to the (name of table or layer) node attribute table.PIPE_SIZE: This value is the inside pipe diameter in inches.MON_INST: This is the month of the pipe installation.PIPE_ID: The value is a combination of the values in the UP_STRUCT, DN_STRUCT, and PIPE_LABEL fields. This is the 17 digit identifier of each pipe segment and is a key attribute of the pipe line data layer. This field named PIPE_ID relates to the field in the Annotation Pipe feature class and to the field in the Wye line feature class data layers.REMARKS: This attribute contains additional comments regarding the pipe line segment.DN_STA_PLS: This is the tens value of the downstream stationing.EASEMENT: This value denotes whether or not the pipe is within an easement.DN_STA_100: This is the hundreds value of the downstream stationing.PIPE_SHAPE: The value signifies the shape of the pipe cross section.
