Water and wastewater infrastructure engineering

Civil Engineers

Civil engineers in this niche design the systems that move, treat, store, and discharge water safely, from lift stations and treatment plants to distribution and runoff networks. The work is distinct because every design has to balance public health, environmental rules, and real-world site constraints, so the main tradeoff is between what would be ideal on paper and what can actually be built, permitted, and maintained.

What This Role Looks Like in Practice

Civil Engineers sits in the Science category. In practical terms, this role combines day-to-day execution, cross-team coordination, and consistent decision-making under real business constraints.

U.S. employment is currently about ~355K workers, with a median annual pay of $99,590 and roughly 23.6K openings each year. Based on BLS projections, total employment is expected to grow from 368.9 K in 2024 to 387.5K in 2034.

Most hiring paths start with Bachelor's degree in civil engineering, and employers typically expect none of related experience. Many careers in this track begin around Civil Engineering Intern and can progress toward Principal Engineer or Engineering Manager. High-value skills usually include Water and Wastewater Treatment Design, AutoCAD Civil 3D & Drafting, and Hydraulic Modeling (EPA SWMM, HEC-RAS), paired with soft skills such as Critical thinking, Active listening, and Complex problem solving.

Core Responsibilities

A Day in the Life

01 Choose the right treatment approach for wastewater or industrial water based on site needs and regulations.
02 Design treatment plants, pump stations, and control buildings so they can handle the expected flow safely and reliably.
03 Pick equipment such as pumps, membranes, and disinfection systems that will meet performance and compliance targets.
04 Plan how sludge will be handled, treated, stored, or disposed of without creating health or environmental problems.
05 Lay out water supply, distribution, drainage, and runoff networks so water moves where it is needed.
06 Review drawings, calculations, and project details to make sure they meet government standards and fit the rest of the project.

Pros and Cons

Advantages
+ The pay is solid for a bachelor's-level job, with a mean salary of $107,050 and a median of $99,590.
+ There are steady hiring opportunities, with 23.6 thousand annual openings projected.
+ You can enter the field with a bachelor's degree and no required work experience or on-the-job training.
+ The work is concrete and visible: you help design systems that deliver clean water and protect communities from wastewater and flooding.
+ You can build a long career in consulting, utilities, construction, or industrial facilities without changing fields.
Challenges
- Growth is only 5% through 2034, so this is a stable field rather than a fast-expanding one.
- The job is heavily tied to codes, permits, and compliance checks, which can slow projects and create a lot of paperwork.
- Remote work is limited because projects often require site visits, field measurements, and coordination with crews or plant operators.
- The education bar is high: most workers have a bachelor's degree, and a sizable share go on to graduate study, which can add time and cost.
- Career progress can depend on licensure, project budgets, and public funding cycles, so advancement is not always under the engineer's control.
