Engineering our
mountain communities
wastewater treatment plant engineering
We help municipalities, utilities, and special districts plan, design, permit, and upgrade treatment facilities that support reliable operations and long-term regulatory compliance.
Wastewater treatment plant engineering brings together process design, hydraulics, permitting, constructability, and operational planning to safely treat wastewater before discharge or reuse. In Colorado’s mountain communities, treatment plant design also has to account for aging infrastructure, constrained sites, changing flows, regulatory requirements, and the practical realities of keeping critical systems operating during construction.
Whether the project involves a new facility, an aging plant that needs upgrades, or a specific treatment process that is limiting performance, our wastewater treatment engineering team focuses on solutions that work on paper, in the field, and over time.
What wastewater treatment plant engineering includes
Good wastewater treatment plant design starts with understanding how the facility operates today, where the system is constrained, and what it will need to handle in the future.
[ 01 ]
Treatment plant planning and process evaluation
We evaluate existing processes, hydraulic conditions, capacity, equipment, future flows, and regulatory requirements to identify the improvements that will provide the greatest operational value.

Wastewater treatment plant design
Our wastewater treatment plant design services can include hydraulic modeling, process review, clarifier sizing, piping layouts, facility organization, equipment coordination, constructability analysis, cost estimating, and design documentation.

CDPHE permitting and regulatory coordination
Treatment projects need engineering that can stand up to regulatory review. We prepare and coordinate required CDPHE documentation, including Basis of Design Reports, Process Design Reports, Site Applications, and supporting materials.
Wastewater regulations and permitting are considered throughout design so compliance is built into the project rather than addressed late in the process.

Bidding and construction support
A successful design still has to be built without creating unnecessary operational risk. We support bidding, contractor coordination, construction administration, sequencing, and field decisions so improvements can move from design into service with fewer surprises.
Wastewater treatment systems are long-term community assets. The operators and public agencies responsible for them need practical engineering that considers regulatory compliance alongside daily operations, maintenance, budgets, construction sequencing, and future capacity.
Our wastewater treatment engineers support municipalities, water and sanitation districts, utilities, and other public infrastructure owners facing decisions about treatment plant upgrades, system expansion, aging equipment, changing discharge requirements, and long-term capital investment.
Treatment plant projects can also be coordinated with municipal engineering and water distribution system engineering when improvements affect the broader utility system.
Common wastewater treatment plant challenges
//
Aging treatment infrastructure approaching the end of its useful life
[ 01 ]
Existing facilities struggling with current or future regulatory requirements
[ 02 ]
Capacity limitations caused by growth or changing wastewater flows
[ 03 ]
Hydraulic bottlenecks or treatment processes limiting plant performance
[ 04 ]
Constrained sites that require careful equipment and piping layouts
[ 05 ]
Maintaining treatment operations while upgrades are under construction
[ 06 ]
Capital planning, cost estimating, and prioritizing improvements within available budgets
[ 07 ]
Treatment plant problems rarely exist in isolation. A hydraulic limitation may affect process performance. A capacity issue may become a permitting concern. A seemingly straightforward equipment replacement may require piping modifications, operational shutdowns, or construction sequencing that changes the entire project approach.
Early wastewater treatment engineering helps establish existing conditions, clarify regulatory requirements, compare alternatives, understand probable costs, and identify how construction can occur while maintaining reliable service.
That gives operators and decision-makers better information before major design and capital decisions are made.
Our water and wastewater work is grounded in real operating systems throughout Colorado’s mountain communities.
Planning a wastewater treatment plant design or upgrade?
Treatment facilities have to balance compliance, operations, constructability, capital cost, and long-term reliability. Early involvement from an experienced wastewater treatment engineer can help define the real problem, compare practical options, and reduce uncertainty before the project advances too far.
