Developer's Manual & Standard Details

The PWSA Developer's Manual and Standard Details outline the rules and regulations to tap into our water and sewer system. We strive to maintain a positive and transparent relationship with our business community partners. If any requirements are unclear or your property doesn't quite fit into the standards, reach out to the Business and Development Relations Manager to discuss.

Developer's Manual

PWSA's Developer's Manual is a guide on the procedures and regulations for developments tapping into new and existing public sewer or water facilities and for constructing new facilities to be dedicated to PWSA. The purpose of this manual is to describe the development permit application process, the requirements of the application materials, and the developer’s responsibilities. To ensure timely review and approval of tap-in plans, this manual is to be used in conjunction with an open dialogue with PWSA.

At minimum, this manual will be updated annually. More frequent updates may occur as procedures or regulations change. A 2020 update will be coming soon. Check back for details!
