Process/Pipeline Design

Instrumentation and Controls

EA’s professional staff of process, chemical, electrical, and control engineers have designed, installed, and commissioned monitoring and control systems for multiple facilities including water and wastewater treatment plants, chemical injection facilities, storage reservoirs, hydroelectric projects, mine tailings dams, and mine shafts and tunnels. EA works with the client to specify the required flow, pressure, level, and other required instrumentation for the project. EA has designed and installed systems to monitor and control a variety of system parameters including flow rates, fluid levels, system pressures, environmental conditions, process concentrations, ground movement, and weight. Some of these efforts were necessitated not just to streamline data collection and system controls, but to mitigate the safety hazards associated with manual data collection and operation of systems in extreme mountain alpine environments.

Pipeline Alignment & Ground Condition Analysis

EA has supported the planning, design, alignment analysis, ground condition analysis, and modeling of water, gravity sewer, force main, and stormwater pipelines. EA can assist with land and subsurface investigations that help in identifying and selecting the optimum routes. The selected route should include considerations for environmental impact, public safety, ease of constructability, right-of-way, land acquisitions, and cost. EA has the experience to address typical installations, installations with unique circumstances, and installations that have experienced complications. Our technical team can provide support to all stages of the pipeline lifecycle.

Evaporation Ponds and Impoundments

Surface Water Discharges

Surface water discharge is implemented on production facilities where an ephemeral channel, river, or creek is located nearby. These designs often require higher levels of continuous water treatment to meet state and federal standards. Typically, water quality analyses, water balances, and geochemical modeling are performed and available treatment processes are evaluated to determine the most appropriate treatment method for the site conditions. Once a treatment process is identified, various technologies are evaluated and the optimal process is implemented to meet the limitations of the permit. EA has also worked with state regulatory bodies to develop and implement trading programs, alternatives analyses, and alternative points-of-compliance in lieu of treatment to meet discharge limits.

Underground Injection

Underground injection facilities are implemented in locations where a high volume of produced water needs to be disposed and other solutions are not economically possible. These facilities can be designed to accept commercial or private fluids. Normally these facilities are designed to skim residual oil from incoming produced water providing clients with an extra source for revenue. These facilities require UIC permitting and APDs for new wells. In addition to permitting, EA provides its clients with a complete set of civil, mechanical, and electrical drawings necessary to construct these turnkey facilities. Additional services offered include preparing operation and maintenance manuals, facility operator training, construction oversight, and start-up services.
