The Design Standards Manual is a guide for the planning, design, and construction of stormwater and sanitary sewer collection systems, water distribution systems and facilities, and associated activities for City Utilities.

Guidelines, basic design criteria, standards, and mapping are presented in the Standards. Design of storm sewers Generally, storm sewers are designed to provide safe passage of vehicles, and to collect, convey and discharge for frequently occurring, low-return-period storms.

Storm sewer design involves estimation runoff from an area design of the sewer and other hydraulics structures in the drainage system. Design flow. Providing for the consideration of H.

Design and Construction of Urban Stormwater Management Systems presents a comprehensive examination of the issues involved in engineering urban stormwater systems.

Gravity Sanitary Sewer Design and Construction provides theoretical and practical guidelines for the design and construction of gravity sanitary sewers. In no case less than mm is used. In general, maximum mean velocities of 2. Design Procedures Layout the sewer: Draw a line to represent the proposed sewer in each street or alley to be served. Near of on the line; indicate by an arrow the direction in which the wastewater is to flow.

Except in special cases, the sewer should slope with the surface of the street. It is usually more economical to plan the system so that the wastewater from any street will flow to the point of disposal by the most direct and, consequently; the shortest route.

In general, the laterals connect with the mains and these; in turn connect with the trunk sewer, which leads to the point of discharge or to an intercepting sewer. Locate the manholes: Locate a manhole at: 1 Changes in direction; 2 Changes in slope; 3 At pipe junctions with the exception of building connections; 4 At the upper end and ends of all laterals for cleansing and flushing the lines; and 5 At intervals from 90 to m or less, as required.

Give each manhole an identification number. Establishing the limits of the service area: Sketch the limits of the service areas.

Search the limits of the service area for each lateral. If a single lateral will be required to accommodate an area larger than can be served by the minimum size of sewer with the minimum slope the area should be subdivided further. Where the streets are laid out assume that the limits are midway between them. If the street layout is not shown on the plan, the limits of the different service areas cannot be determined as closely and the topography may serve as a guide. Determine the area of each service area.

Measure the area of each service area by using a scale, and enter the value on the map. Summarize the basic design criteria. Design period usually saturation period used ; b. Population density; c. Residential wastewater flow Obtain the peaking factor ; d.
