CDIM professional engineers designed a water recycling system to create deionized water from corrosive rinsewater. Work included concept development, construction drawings, bidding, and construction oversight. CDIM also prepared a closure plan with cost estimate, operation and maintenance manuals, and tank integrity assessment for the new system, all in accordance with California Code of Regulations, Title 22 hazardous waste requirements.

CDIM prepared basis of design and process engineering report after establishing owner requirements, which included sampling wastewater and chemical testing to establish water quality. CDIM then prepared conceptual design and plans and specifications, which were used to identify contractors and obtain cost estimates. CDIM then worked with the selected contractor to develop plans and specifications for site engineering, plumbing and process engineering that would integrate the water treatment system into the existing plating and water recycling infrastructure. CDIM then oversaw structural, electrical and fire protection engineering and provided engineering support during construction and commissioning, including overseeing pressure tests for all piping and hydrostatic tests for vessels and containment areas. CDIM documented work all in as-built drawings. 

Project Highlights:

• Designed and oversaw construction of ion exchange, neutralization and evaporation system for recycling of plating rinsewater.

• Developed bid documents for construction.

• Assisted in contractor procurement through LBNL processes.

• Coordinated with Certified Unified Program Agency (CUPA).

• CDIM helped LBL achieve sustainability goals by increasing water reuse.
