Notification of Completion of Construction
All applications for a construction permit must include the following three items:
In addition, the other forms (Schedules 2a through 16d) are required based upon the nature of the project (
e.g., water mains, well construction, chemical feed, etc.). The Water Supply Service Agreement form is required for all projects where the applicant is someone other than the supplier of the water.
Once the project is completed, the Notification of Completion of Construction form or postcard that is supplied with the permit must be submitted to indicate the project was completed in accordance with the approved plans and specifications.
The reference document that contains a defined procedure and checklist which can be used to help understand and meet the compliance requirements for the installation of public water supply test and observation wells is available. This procedure and checklist is entitled the
Test Well and Observation Well Guidance and Procedures for Drilling Projects Related to Public Water Supplies.
