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.

On March 5, 2007, the standards were posted online. These standards have been utilized by the Department for many years and continue to be periodically updated online as needed.

New standards and standard details for use with reclaimed water systems have been introduced in June of 2008. Also introduced were design guidelines for turbo meter installations, 4 to 10 inches with by-pass.

Your feedback is important and should be sent via email to [email protected].


The Miami-Dade Water and Sewer Department is responsible for the operation and maintenance of wastewater collection and water distribution systems in most of Miami-Dade County. The Department supplies wastewater service and quality drinking water to more than 90% of the county's residents.

In 1995, the Department was recognized as the largest wastewater and water utility in the southeastern United States. The Department's water system includes several wellfields and three water treatment plants with a combined rated capacity of over 470 million gallons per day (mgd). The system is also comprised of three regional wastewater treatment plants and a collection system made up of over 3,000 miles of gravity sewer lines, 700 miles of force mains and over 900 pump stations.

In the past, the Department established minimum standards pertaining to the design and construction of public and private utilities by the Department's staff, other municipalities and governmental agencies within its service area and private parties engaged in the design or construction of water and wastewater utilities in Miami-Dade County and its unincorporated areas.

These standards were published and sold by the Department in several publications. In August of 1979, the Department published its Standards containing standard details. In February and August of 1985, the Department published Specifications for Gravity Sanitary Sewer Systems using Poly (Vinyl Chloride)(PVC) Pipe and Fittings and Construction Specifications for Donation Water Mains, respectively.

Later, in October of 1989, the Department published Construction Specifications for Donation Wastewater Pumping Stations and Force Mains. In the past, updates to these publications were issued via public notices and distributed by the Department.

The standards and specifications contained herein are the result of revisions and re-arrangement of the aforementioned publications. The compilation of these documents shall henceforth comprise the Miami-Dade Water and Sewer Department's Design and Construction Standard Specifications and Details. All existing Department standards that are in conflict with this manual are hereby superseded.

This publication is presented in CSI format and will be published annually, in its entirety. However, the Department reserves the right to update the contents herein, as required, via public notices, which will be issued free of charge.

All proposed amendments to this publication may be submitted in writing to the Chief of the Engineering Division at the following address Miami-Dade Water & Sewer Department, P.O. BOX 330316, Miami, Florida 33233-0316.

Miami-Dade Water & Sewer Department Standard Details



This publication is arranged in CSI format, with the exception of the various utility construction which comprise the UC-XXX Series of specifications sections. It is organized so that all standards or minimum requirements governing a specific product, design, construction method or trade are grouped together and cross-referenced. The utility construction specification (i.e. found in Part I) are arranged prior to and contain references to the technical specifications of Parts II and III.

The Design and Construction Standard Specifications and Details is comprised of seven major subdivisions. These subdivisions or parts of this publication are designated by Roman numerals (I, II, ...) and labeled as PART I, PART II, etc. Each part shall contain specification sections relating to a specific subject, product, construction method or trade.

The range listed above in the outline for the specification sections of each PART indicate the upper and lower limits of possible section numbers and are not intended to denote actual section numbers included herein.
Sections are further subdivided into three sub-sections or parts which are designated by Arabic numerals (1, 2 and 3). These sub-sections are characteristic of the three part CSI Section Format, whereby Part 1 is entitled GENERAL, Part 2 is entitled PRODUCTS and Part 3 is entitled EXECUTION. Some sections may not require Part 2 and/or Part 3, therefore those parts may be omitted or identified as "Not Used". Each section starts with the section number and title and conclude with the statement "END OF SECTION"

The presentation of these standards in binder was designed for ease of use, reference and maintenance by the user. Future updates or revisions to this publication will be accomplished by modular replacement of the individual section being revised. Where new sections are added to this publication, a revised index shall also be provided.

Each specification page included in PART I, II and III shall include the following information: section number, page number, the acronym "MDWASD", the revision level and revision date, as shown on Figure 1, below. 

  09900 - 3
  Figure 1  

Figure 1 illustrates an example of a page 3 of Section 09900, which has an effective date of May, 1995 and is the third revision level.
