Standard Drawings, Design Manual, Specifications & AutoCAD Sample Drawings

Standard Drawings
MSD has updated its acceptable Standard Drawings. These details are for use with MSD designed projects and for private development design. The details are expected to be used as presented, but modifications may be accepted on a case-by-case basis. The appropriate drawings need to be referenced with each project within the Special Provisions and drawings. Any modification from a standard should be shown as a separate detail within the set of plans. Standard Drawing details should be referenced by number on the plans.

The drawings are meant to be flexible documents. There will be revisions and additions from time to time. It is important that the users make recommendations for changes to the details or suggest the creation of new details. All comments will be reviewed.

For your information, MSD is not providing copies of these drawings in digital form on a CD. Instead, drawings are available for download at the bottom of this page.

Green Management Practices (GMP) Manual A new addition to the MSD Design Manual is Chapter 18, Green Management Practices (GMP) Manual. MSD is promoting GMPs to supplement traditional development and construction methods to encourage environmental sustainability and economic growth. Green infrastructure is a term commonly applied to stormwater GMPs such as pervious pavement, rain gardens and bioswales. These GMPs are designed to infiltrate rain water into the ground rather than it running into MSD’s combined sewers or the community’s waterways. The GMPs should be considered as a list of tools and should be implemented based on the site conditions and stormwater management needs to comply with Clean Water Act, post-construction stormwater water quality and quantity requirements.

Design Manual
The MSD Design Manual is a guide for the planning and design of stormwater systems, flood protection works, sanitary sewers, erosion control structures, small sanitary pump stations, small wastewater treatment plants and associated activities MSD.

The Design Manual identifies a single set of standards, submittal requirements and approval procedures to be used in the planning and design of projects within the MSD service area. The Design Manual is not intended to serve as a step-by-step design methodology nor can the Design Manual address every situation, which may arise. The application of sound engineering/surveying principles and judgment combined with the information contained in the manual are necessary to complete the planning, design, and preparation of related construction documents for stormwater, sanitary sewer and/or wastewater projects. Approval of plans by MSD shall not relieve the designer or developer from required compliance with the provisions of the manual unless a written variance is received from MSD.

MSD's Design Manual can be downloaded from links at the bottom of this page.

MSD Specifications
MSD Standard Specifications and Inflow & lnfiltration (I/I) Specifications have been developed for construction and rehabilitation of stormwater systems, flood protection works, sanitary sewers, erosion control structures, small sanitary pump stations, small wastewater treatment plants and associated activities within MSD's service area. In particular, the Standard Specifications, the S- Pages, are typically for new construction of facilities and appurtenances. They provide a description of work, materials that are approved for use, and the necessary workmanship and procedures to be followed in constructing the various types of projects. They form a vital part of the contract documents for MSD capital construction as well as privately funded developments. They are expected to be interpreted in cooperation with the project drawings and as a complement to them.

The Inflow and Infiltration (I/I) specifications are included in the II- pages. These are an approved set of standards for rehabilitation of MSD systems. Primarily, they were developed to help reduce the effects of I/I by defining the materials, describing the work and the process for various repair types.

Copies of the both sets of specifications are available for download from this page.

AutoCAD Sample Drawings 

Chapter 4 of the MSD Design Manual outlines AutoCAD standards in order to provide consistency with respect to plan and document development and for compatibility with respect to the sharing of data and document storage. Sample drawings have been created in order to demonstrate the use and function of the standard layers, linetypes, and symbols for typical plan sheets. Not all plan sheets or situations have been addressed.

MSD is in the process of developing a AutoCAD Civil 3D template. This template is a continuously evolving project. As consultants use this template MSD would like feedback including, but not limited to, styles that needed to be added, removed, or revised. If you have created a style that you believe should be included please let us know.
