Description:

Abstract:

Water & Sewer line distribution areas for public drinking water systems with at least 15 service connections used by year round residents or regularly serve at least 25 year round residents.

Purpose:

For risk assessment for contaminated sites, to make interconnection assessments, and to reduce monitoring costs for water systems.

Use_Constraints:

User is required to read metadata completely before using the data. The information provided in this coverage is a subset of spatial databases developed by the New Hampshire Department of Environmental Services (NHDES). Development of these databases is an ongoing project; they may not contain all existing and potential sites, stations, or threats. The NHDES is not responsible for the use or interpretation of this information, or for any inaccuracies in the site names, tax map and lot information, or locations. All information is subject to verification. These data are to be used for planning purposes only; distribution is discouraged.

Data_Quality_Information:

Logical_Consistency_Report:

Initial check by NHDES after coverages were first available from water systems to verify whether coverage was accurate. Periodically water systems view the coverage and submit changes.

Completeness_Report:

Distribution lines for new community systems that have come on line after 9/03 are not digitized in the coverage.

Lineage:

Process_Step:

Process_Description:

Developed by selecting all roads (in the DOT road coverage layer) that are serviced and then buffering them by 200 feet. Specifically the lines are not pipelines, they are roads that have water/sewer service.

Ordering_Instructions:

Please contact NHDES for information about acquiring this data layer. Most coverages are available through ftp site (see Online Linkage). To address homeland security concerns, access to some of these data sets is available only to users who present a valid personal identification number (PIN) and password. These data sets have an access constraint set to Upon NHDES Approval. Users can apply for a PIN and password using the OneStop Data Retrieval Registration Form (<http://www.des.state.nh.us/gis/onestop/>). Applicants should be very specific when providing information on the registration form to enable NHDES personnel to determine their eligibility. For more information on what criteria is necessary to receive a PIN/password please visit <http://www.des.state.nh.us/factsheets/co/co-14.htm>. Once the applicant has been provided a PIN/Password, the applicant shall be the sole responsible party for the information they receive using the PIN/Password that has been issued to said party. The applicant shall be responsible for the accuracy of the information submitted in a request for a PIN and Password that will allow said applicant to access certain information held by the Department of Environmental Services. The applicant shall understand by submitting a registration form, said applicant shall be responsible for the PIN and Password they receive and for any and all information collected using the PIN and Password, and that NO LIABILITY IS INCURRED BY THE STATE by reason of providing the requested access.
