Construction & Development
Building something? Did you know that all new construction, changes of use and most renovations for residential and commercial projects must be evaluated and approved by the Water & Sewer Department (WASD)?
WASD's role is to evaluate the project's proposed use to ensure the availability, integrity and capacity of our infrastructure, which is designed to protect public health.
Projects with Existing Water or Sewer Service
Read about setting a water meter on existing water service, both with and without an executed water or sewer agreement.
Projects with New Water or Sewer Service
Information about new first-time water service installation from an existing water main, as well as first-time connections to the sanitary sewer system.
Water or Sewer Service Agreement

Pre-Approved Product List
The Pre-Approved Product List is for contractors, developers and suppliers to submit products used in construction for approval to the Water and Sewer Department.
Design & Construction Standards
These "standards" are intended for developers, engineers and contractors to design and construct water, sewer and reclaimed water infrastructure projects that will subsequently be donated to the Water and Sewer Department.
Electronic Plans Review allows registered customers to submit plans for review and approval in electronic file formats. Reviews, markups and changes can be exchanged electronically, thus improving efficiency.
Information if you wish to request a pre-construction meeting with the Water and Sewer Department (WASD) on a project that includes an executed water and/or sewer service agreement.
To be eligible to bid on construction contracts with the Miami-Dade Water and Sewer Department, you must be licensed to perform the specified type of work in Miami-Dade County.
Construction Project Requests
Learn about requests for projects within or along state roads; the re-platting or permanent closure of roads with existing water and sewer infrastructure; and excavations.
Cross-Connection Control & Backflow Prevention
A cross-connection is an actual or potential link between the potable water supply (water safe for human consumption) and a non-potable source (any other type of liquid, gas or substance not fit for consumption and that can affect water quality).
A cross-connection can be avoided by eliminating the link between the two sources. If the link cannot be removed, then the potable water supply must be protected through the use of a backflow prevention assembly.
