Storm & Sanitary Sewer Design

EDSI offers a full range of hydrologic and hydraulic design, from traditional collection/containment/conveyance systems to innovative low-impact development practices that mimic the pre-development hydrology.

 

EDSI actively promotes the advances in stormwater volume, velocity and pollutant reductions into the watershed through natural methods. Innovations such as rain gardens, porous pavements and other non-structural methods are naturally aesthetic and environmentally friendly alternatives to traditional bio-retention techniques. The firm also designs extended detention wetlands, which drain slowly so that pollutants are filtered from run-off before entering the surface waters.

 

Hydrologic & Hydraulic Design Tasks:

– Storm Sewer Design

– Open Channel Design

– Natural Channel Design

 

Stormwater Management Tasks:

– Low-Impact Development (LID)

– Stormwater Best Management Practices (BMPs)

– Water Analysis and Modeling

– Water Quality Analysis

– Bio-Stabilization

– Erosion & Sediment Control

– Drainage Master Planning

– Detention/Retention Ponds

Washington University Stormwater Master Plan

Washington-University-in-St.-LuisLocation: St. Louis, Missouri

Washington University recently retained EDSI as a prime consultant to develop a comprehensive and long-term stormwater master plan for the Campus that satisfied the interests of both the University and MSD, and exceeded the current requirements set forth by MSD.

 

Central to our approach was engineering a variety of non-structural low-impact development recommendations that were environmentally sensitive in their approach, while significantly effective in their ability to reduce the water volume, velocity and overall mass of pollutants discharged into the storm sewer system.

 

EDSI successfully prepared an approach which utilized some of the most innovative best management practices (BMPs) available. The long-term impact in this approach is projected to reduce the Campus stormwater runoff by more than 55%, with the University demonstrating leadership in environmental stewardship through remediation strategies that better replicate the natural hydrologic cycle.

 

 

Deer Creek Sanitary Relief

Location: St. Louis, Missouri

EDSI was selected as the prime consultant to provide design services for the first phase of a multi-phased project to relieve wet weather surcharge conditions. The EDSI team consisted of local engineering firms as well as experts from across the country.

 

The design study included evaluation of several alternative alignment and construction methods. The selected approach encompassed 8,000 linear feet of 20-ft. diameter relief sewer, installed with a tunnel boring machine in a rock tunnel 100-140 feet deep. The project consisted of upstream and downstream tunnel shafts, three drop shafts connecting near surface sewers to the deep tunnel, four access area shafts for maintenance and inspection, and a pump station to empty the tunnel after each wet weather event.

 

A critical issue with this project was the questionable consistency of ground conditions, fill groundwater connectivity, and shoring/dewatering systems. A total of 32 borings were drilled along the proposed alignment in order to use the field explorations as the basis for forming geotechnical recommendations for design and construction.

 

 

Missouri River Wastewater Treatment Plant
 

Missouri River WWTPLocation: St. Louis, Missouri

EDSI was selected to provide design services for the expansion of the secondary treatment processing and disinfection facilities located in the Missouri River Service Area in Maryland Heights, Missouri.

 

EDSI offered roadway design, site grading plans, site drainage plans, miscellaneous civil site work and Phase II Engineering including a complete boundary, improvement and topographic survey to locate buildings, structures, encroachments, paved areas and utilities and curbs as required for the preparation of the design plans. EDSI established six horizontal and vertical control points that can be used for construction of the project; locate property lines within the survey boundary and elevations on pavements, utilities and structures.

 

 

McKnight Road Combined Sewer Outfall
 

McKnight CSOLocation: City of St. Louis, Missouri

EDSI served as a sub-consultant to perform surveying and engineering design to eliminate current issues of bypasses and backups, improve storm water collection, and extend the lifetime of the existing sanitary sewer system that serves the River Des Peres watershed.

 

Responsibilities included topographic survey, hydraulic modeling, PIRR evaluation and report, design study evaluation and report, along with “preliminary” and “final design” construction documents, encompassing drawings, specifications, quantity takeoffs and construction cost estimates.

 

 

Ferguson & Raymond Combined Sewer Outfall Interceptor Sewer Separation
Location: University City, St. Louis, Missouri

EDSI served as a sub-consultant for the design of improvements to the existing storm sewer system in the University City watershed for the City of University City. The design services included improvements to almost 1,300 lineal feet of 12-inch to 21-inch storm sewers, ten new/rebuilt storm inlets, five new inlet manholes, and three storm water outfalls.

 

Responsibilities included topographic survey, strip map preparation, hydraulic modeling, PIRR evaluation and report, design study evaluation and report, along with “preliminary” and “final design” construction documents, encompassing drawings, specifications, quantity takeoffs and construction cost estimates.

 

 

Eva-Wabash Sanitary Relief
Location: City of Berkley, Missouri

EDSI was selected as a sub-consultant to provide survey and design services to improve the conditions of existing sanitary sub-trunk sewer in the City of Berkley. The project included designing and preparing plans, specifications, strip maps and easement documents for approximately 12,450 feet of 12-inch to 36 inch sanitary sewer, to alleviate residential basement backups, flooding and overflow and to reduce or eliminate the wet weather bypasses along the Eva Wabash sanitary sub-trunk sewer.

 

Several critical issues arose during the project. One was working with public and railroad right-of-way entities to trace the portions of the sewer that ran along industrial and residential properties. Another issue was a near-by radioactive contaminated area at Eva Avenue which was being decontaminated by the Corp of Engineers. EDSI coordinated with other agencies to make certain all work performed on the project followed procedures to ensure safety and remain within the proper boundaries.
