Design Guidelines is an official updated version which replaces the preliminary version published on this website in June 2001. As technology is in perpetual evolution, chapters or sections of this guide will be updated periodically.
Please note that Design Guidelines is now in two parts. Part 1 contains all the information the designer may require when planning a facility, including the main and most frequent criteria. Part 2 comprises more detailed descriptions, additional design information as well as notes on works occurring seldom. Part 2 is set up to make links with the contents in Part 1 easy.
You are invited to read Chapter 1 (English) and Chapter 2 (French) of Part 1 in order to find out about the fields of application of the guidelines and learn what major changes have been made to its format. This tool has become indispensable and we hope you will enjoy using it.
Chapters followed by a star have been modified on February 4, 2015 (fifth update). For more details, refer to the Frequently Asked Questions (FAQ).

3. Regulation highlights
The Regulation respecting the quality of drinking water was adopted on May 30, 2001 and was enforced on June 28, 2001. Many standards were updated or added by this regulation, which greatly influenced the design of drinking water production facilities.
Design guidelines for drinking water production facilities (Design guidelines) was created by the Ministère in order to replace the sections on water uptake found in Directive 001, as well as Directive 002 on drinking water treatment. Design guidelines is available on the MDDELCC’s website and will be updated regularly. Therefore, we invite you to subscribe to a mailing list which will keep you informed of changes to Design guidelines as soon as they are made.
Design guidelines also covers design criteria for water uptake due to its main role in required treatment levels and therefore in the choice of a final solution. Nonetheless, drinking water distribution systems also play a major role in treatment design and water quality. For this reason, it is also important to consider the following phenomena when designing a drinking water treatment facility: chlorine demand in distribution systems, formation of disinfection by-products (THM, HAA, etc.), corrosion problems, bacterial growth, cross-connections, water infiltration by pressure drop, etc. Therefore, water suppliers should use distribution management strategies to maintain acceptable drinking water quality from source to tap.
However, Design guidelines does not cover drinking water distribution, and therefore, the sections of Directive 001 which address drinking water distribution (pipes, pump stations, drinking water reservoirs, etc.) remain the only official references available.
Design guidelines was written in collaboration with numerous specialists, including design engineers, manufacturers’ representatives, university specialists and municipal and provincial public workers. This work was conducted under the supervision of RÉSEAU environnement.
