Water Supply Section - Well and Water Use Permit Data

Data requests

The TEPP (Technology Enabled Permitting Process) is an automated program that the Water Supply Section uses to store and retrieve water well data derived from permit applications, well completion and abandonment reports. Searches are performed by querying a number of parameters including property owner, permit number and geographic location. A list of the information available from TEPP can be found on the TEPP checklist. Explanations of the TEPP codes contained in the report are in the TEPP code descriptions.

The information stored in TEPP is by no means exhaustive since it does not contain complete permit data on wells installed prior to 1985. The submission of a list of data generated by running a search by itself is not satisfactory if the data will be used to determine surrounding groundwater use for the purpose of obtaining a permit for waste storage, disposal, or treatment. We suggest combining the TEPP search with door-to door surveys and a review of county tax maps in order to obtain complete and detailed well information.

You may also access public data and FOIA information through our Delaware Open Data page at . This link includes data for energy and environment related categories, including but not limited to, well permits and permitted septic systems.

Procedure for obtaining TEPP data:

  • Complete the FOIA request form
  • Provide a map clearly showing the area to be searched and all major roads and crossroads.
  • Provide the county and tax map number.
  • Complete and include the TEPP checklist.
  • Expect a minimum of two weeks for processing the request.
  • The report will be emailed after completion of the project.
  • Public records may be reproduced. Photocopies will be made available upon request at the rate of 10 cents per page when copies exceed 250 in response to a request, unless proof of not-for-profit status is provided. Please see the DNREC Policies and Procedures Regarding FOIA requests for a full explanation of fees.
