Utilities & Drainage

Design of stormwater, sanitary sewer, and water distribution systems.

What We Deliver

Our Utilities & Drainage service provides expert design of site utilities and stormwater management systems. We design water distribution, sanitary sewer collection, storm drainage systems, dry utilities (electric, gas, telecom), and coordinate all utility infrastructure. Our civil engineers perform hydrologic and hydraulic calculations, size pipes and structures, design detention/retention facilities, and ensure compliance with local regulations. We create utility plans, profiles, details, and specifications supporting bidding and construction. We coordinate utility conflicts, establish construction sequencing, and work with utility providers ensuring designs are constructible, cost-effective, and meet all functional and regulatory requirements.

Water distribution design including main sizing, fire flow requirements, and service connections

Sanitary sewer design with gravity and force main systems, pump stations, and manholes

Stormwater management including pipe networks, detention, water quality treatment

Dry utility coordination for electric, gas, telecommunications, and other services

Hydrologic/hydraulic calculations supporting proper system sizing and performance

Utility conflict resolution coordinating all infrastructure in congested corridors

Frequently Asked Questions

What utility systems do you design?

We design potable water distribution, sanitary sewer collection, stormwater drainage, electric distribution, natural gas, telecommunications (fiber, copper), district cooling/heating, reclaimed water, fire protection, and specialty utilities—providing complete utility infrastructure design for all project types.

How do you handle stormwater regulations?

We analyze local stormwater requirements (detention volume, peak flow reduction, water quality), perform rainfall-runoff calculations, design detention/retention facilities, specify water quality BMPs (bioretention, sand filters, hydrodynamic separators), and prepare stormwater reports—ensuring full regulatory compliance.

Can you coordinate with utility providers?

Yes. We communicate with water/sewer utilities, electric companies, gas providers, and telecom carriers—obtaining utility requirements, coordinating connection points, submitting utility plans for review, addressing comments, and facilitating utility extensions or relocations required for projects.

Do you perform hydraulic modeling?

Absolutely. We use StormCAD, HydroCAD, HEC-RAS, and other hydraulic modeling tools to analyze system performance, verify adequate capacity, identify constraints, evaluate alternatives, and optimize designs—though we're not limited to these platforms and adapt to project-specific analysis tools.

How do you resolve utility conflicts?

We perform 3D utility conflict analysis, identify horizontal and vertical conflicts, evaluate relocation alternatives (depth adjustment, horizontal shifts, material changes), coordinate sequencing, and develop construction phasing—resolving conflicts before construction and minimizing field coordination issues.
