2.5 MGD Industrial/Municipal Wastewater Treatment System Design-Build

Industry: Oil Refinery

After conducting a comprehensive feasibility study and cost/benefit analysis, EEC designed a 2.5 million gallon per day (MGD) wastewater treatment plant at a refinery in China to meet new stringent discharge standards.

Project Highlights

• Designed a 2.5 MGD treatment system
• Provided turnkey feasibility study, design, equipment procurement, construction management, start-up, and operator training
• Completed physical, chemical, and biological treatment for oil and grease, toxic organics, suspended solids, ammonia, chemical oxygen demand (COD), and biochemical oxygen demand (BOD)
• Constructed stormwater diversion and treatment

Pretreatment Program Upgrade

EEC was retained by a large city in the western United States to respond to a state audit and notice of violation (NOV) that required an extensive upgrade of the City's pretreatment program. EEC is working side-by-side with the City to upgrade its legal authority, develop new local limits, issue industrial user permits, and provide inspector training.

Project Highlights

• Pretreatment program assessment
• Pretreatment ordinance and local limits development
• Key program documents and procedures development
• Industrial waste survey development and implementation
• Significant industrial user (SIU) permit review and revision

Chemicals of Emerging Concern Study

EEC conducted a comprehensive study of chemicals of emerging concern for a large pharmaceutical manufacturer. The study analyzed endocrine-disrupting effects of key chemicals used in the company's drug manufacturing processes. EEC investigated the potential adverse impacts of the manufacturer's effluent on the local publicly owned treatment works (POTW) processes, as well as acute and chronic impacts on the aquatic life in the POTW receiving waters. The study resulted in a phased raw material substitution and new best management practices to prevent harmful discharges.

Project Highlights

• Chemical usage and manufacturing processes evaluation
• Research on endocrine-disrupting effects and European Union and USEPA discharge standards requirements
• POTW removal efficiency evaluation and projections
• On-site treatment feasibility analysis
• Corporate-wide raw material substitution plans

Water/Wastewater GIS Data Development and Conversion

EEC has been providing GIS services to the City of Santa Ana’s Water Resources Division since 2004. EEC developed a database and data entry procedure that transferred data from old water service index cards to digital data, complete with GIS representations. The partially automated database and data entry process allowed the Division to quickly enter information, reducing the time needed to enter tens of thousands of records. This water service data can now be queried in the GIS. EEC has also assisted Santa Ana in creating GIS feature classes based on existing tabular data. EEC has developed two methods for creating water or sewer laterals feature classes. These methods have a significant amount of automation which reduces the manual effort necessary to create service laterals.

Project Highlights

• On-site GIS support
• Geodatabase editing
• Feature class development automation
• Map document development
• Software implementation and update
• Graphical user interface development
• Customized tool development
• Massive data migrations

Wastewater Work Order and Asset Management System

Industry: Municipal Wastewater

EEC is in the process of developing a work and asset management system for Costa Mesa Sanitary District (CMSD). The computerized maintenance management system (CMMS) at the heart of the system is Azteca Systems’ CityWorks. The system is being developed in conjunction with an EEC-designed geographic information system (GIS), using Esri’s ArcGIS. The GIS and CMMS will be seamlessly integrated to revolutionize the way CMSD manages day-to-day operations and plans for the effective use of its wastewater collection system.

Project Highlights

• State-of-the-art CMMS utilizing CityWorks technology
• Seamless integration with existing wastewater collection network GIS based on industry standard data models
• Full integration with Esri’s ArcGIS platform
• Foundation for future system expansion that includes mobile, web, and modeling technologies

FOG Control Program Development and Implementation

EEC has developed more than 20 fats, oils, and grease (FOG) control programs throughout the United States, encompassing ordinance development, program management, and inspector training. Based on EEC’s unique FOG control expertise, many cities and wastewater districts have contracted EEC to manage their FOG control programs including performing all of the food service establishment (FSE) compliance inspections and preliminary enforcement.

Project Highlights

• Developed more than 20 FOG control programs
• Performed 13 FOG characterization studies involving sewer line hot spot and source identification utilizing closed-circuit television (CCTV)
• Developed 12 FOG control ordinances and FSE permitting programs
• Inspected more than 8,000 FSEs, including grease interceptor and kitchen best management practices (BMPs)
• Trained more than 400 FOG inspectors
  

Municipal Stormwater Program Development and Implementation

Industry: Municipal Stormwater

EEC developed and implemented a stormwater program for the City of Stanton, California to obtain compliance with the City’s national pollutant discharge elimination system (NPDES) permit and meet the objectives of the MS4 program. EEC developed the program plans, updated the City’s ordinance, conducted the initial inspections, and trained the City’s inspectors to allow them to manage their own program.

Project Highlights

• Development of local implementation plan (LIP) and enforcement consistency guide
• Development and evaluation of stormwater pollution prevention plans (SWPPPs)
• Inventory, prioritization, and inspection of municipal, industrial, commercial, and construction facilities
• Assistance with public outreach and education programs
