Drainage Design

Agha Engineering LLC (AEL) is a renowned leader in urban drainage system design. Specializing in innovative drainage design and Hydrology and Hydraulics (H&H) analysis, Agha Engineering LLC has become the preferred firm to deliver quality services at local and state agencies including the Harris County Flood Control (HCFCD), Harris County Engineering Department, Harris County, U.S. Army Corps of Engineers, FEMA, Texas Department of Transportation (TxDOT), the City of Houston, etc. With a strong background in Hydraulic and Hydrologic projects, we have surpassed and exceeded clients’ expectations. 

Our team of experts brings together a wealth of experience and technical knowledge to provide innovative solutions for drainage design and management. We understand the complex dynamics of urban environments and have developed a unique approach that integrates engineering expertise with a deep understanding of the hydrological cycle. 

At AEL, we are fluent with the revised ATLAS 14, county and local criteria, as well as multiple drainage modeling software including for steady and unsteady state analysis using 1D and 2D modeling. We take pride in being one of just a handful of companies that utilizes OpenRoads Drainage SUDA/SU technologies coupled with CivilStorm for storm sewer analysis and design. Our staff is well InfoWorks ICM and SWMM 1D/2D transient modeling. We offer HEC-RAS 1D/2D modeling for hydraulics and floodplain modeling and employ a staff that is well versed in GIS. 

Our current portfolio includes delivering a preliminary engineering report (PER) for the $65 million Boudreaux SWB and Keegan’s Bayou SWDB projects for Harris County Flood Control District (HCFCD). 

We are proud to have contributed to the design and implementation of effective and efficient urban drainage systems across various states and cities. Our work in urban drainage system design and expertise in roadway drainage has helped mitigate flood risks while enhancing the sustainability of urban landscapes.
