Stormwater and Drainage Infrastructure in El Paso, TX
El Paso receives under 10 inches of annual rainfall, but that statistic is almost irrelevant to drainage infrastructure design. Roughly 50 percent of the city's annual precipitation falls during a 10-week monsoon window between July and September, often as localized convective storm cells that deliver 1 to 2 inches in under an hour on surfaces that are nearly impermeable after months of dry crust formation. The caliche hardpan that underlies most commercial and industrial sites has essentially zero infiltration capacity during monsoon events — all stormwater becomes runoff, and it moves fast across flat desert terrain toward arroya channels and detention basins. Concrete Contractors of El Paso builds drainage infrastructure with that hydrology as the design baseline. We construct concrete-lined detention basins and arroya conveyance channels where engineered grade changes and concrete lining prevent embankment erosion that could compromise the structure between annual maintenance cycles. We coordinate TCEQ SWPPP compliance documentation with the civil engineer, install concrete inlet and junction box structures with EPDM-gasketed pipe connections that resist El Paso's alkaline groundwater chemistry, and verify drainage flowlines match permitted design through as-built elevation surveys.
Stormwater infrastructure in El Paso is designed for two competing realities. For 10 months of the year, the Chihuahuan Desert site is bone dry — drainage structures sit empty, detention basins function as open land, and the design engineer's calculations look like theoretical exercises. Then July arrives and a convective cell drops 1.5 inches in 45 minutes on a 50-acre commercial site with caliche subgrade that infiltrates essentially nothing. That concentrated runoff — potentially 500,000 gallons in the first hour — tests every drainage structure at the site simultaneously, and any undersized inlet, inadequate headwall, or improperly graded swale becomes a visible failure. Concrete Contractors of El Paso builds drainage infrastructure with the worst-case monsoon storm event as the design basis, not the 10-year storm that looks adequate on a normal Texas rainfall frequency curve but misses the localized intensity that El Paso monsoon convection produces.
Concrete-lined arroya channel construction is one of the more specialized drainage scopes in El Paso's development environment. Natural arroyas cut through commercial and industrial sites throughout the Horizon City, Mission Valley, and Lower Valley corridors, and El Paso County's arroya master plan requires that development projects either culvert these channels with engineered concrete structures or line them with concrete to prevent bank erosion during design-storm flow conditions. Concrete Contractors of El Paso has constructed concrete-lined arroya channels with riprap energy dissipators at transitions, concrete headwalls at culvert inlets, and grouted boulder drop structures that reduce flow velocity before concrete-lined reaches. We coordinate with El Paso County Public Works on arroya improvement plan review and with FEMA on Letter of Map Amendment documentation when concrete improvements change the arroya's official floodplain designation.
Project Context and Delivery Priorities
In El Paso, stormwater and drainage infrastructure projects usually succeed when preconstruction, field access, and turnover planning are treated as one sequence instead of disconnected tasks. We stay close to the owner, design team, and key trades from the earliest scope conversations so the delivery plan reflects the real site constraints, the expected handoff dates, and the operational pressure that often comes with commercial work in the Borderplex.
Before mobilization, we look at permits, utility windows, haul routes, staging needs, and any overlaps with active operations or neighboring development. That matters in El Paso because many sites combine tight access, weather exposure, and multiple jurisdictional touchpoints. The goal is not only to start work quickly, but to start in a way that protects productivity after the first trade arrives on site.
Once work is underway, the emphasis shifts to sequencing and accountability. We track the work by milestone, keep communication practical, and make sure each handoff leaves the next crew with a clean path forward. That approach helps owners avoid the slow drift that can happen when field decisions, submittals, and change coordination are left to accumulate until the end of the job.
As the project closes out, we focus on punch resolution, documentation, and operational readiness. For owners and facility teams, the best handoff is one that explains what was built, how the systems were coordinated, and what should be watched during the first months after turnover. That is the standard we try to maintain on every stormwater and drainage infrastructure assignment.
Scope Coverage
- Concrete-lined detention basins and arroya conveyance channels designed for monsoon-season hydrology
- Concrete inlets, junction boxes, and EPDM-gasketed pipe connections for alkaline groundwater conditions
- TCEQ SWPPP compliance documentation and erosion-prevention concrete curb and inlet structures
- Drainage tie-ins to city storm systems, arroya channels, and infiltration basins across El Paso and NM
The scope above is most effective when it is structured for the specific end use of the building, the access constraints on the site, and the owner's expected turnover window. We use those priorities to keep the work aligned with the build instead of treating each task as a standalone event.
Delivery Process
- Monsoon-season hydrology review and drainage basin sizing validation with civil engineer
- Concrete trench, structure, and pipe installation sequencing with caliche-layer management
- Flowline elevation verification throughout execution with TCEQ inspection coordination
- Final hydraulic testing and as-built survey documentation for El Paso city and county acceptance
During delivery, we keep an eye on the items that usually create the most friction: submittal timing, trade stacking, access changes, material lead times, and inspection readiness. Keeping those issues visible early makes the schedule easier to protect later.
Why Choose Us

- Concrete-lined arroya channel construction with El Paso County Public Works coordination and FEMA LOMA documentation
- Detention basin concrete outlet structures specified for alkaline groundwater conditions rather than standard DOT precast defaults
Typical Timeline
Detention basin: 4–8 weeks. Concrete arroya channel lining: 6–12 weeks depending on length and drop structure count. Full drainage system with agency acceptance: 8–20 weeks.
Planning Notes For Owners and Operators
Scope clarity matters early because stormwater and drainage infrastructure work often affects downstream trades, equipment placement, and opening dates.
The strongest schedules come from realistic phasing, not optimistic assumptions about how quickly all crews can move through the same space.
If the project touches multiple jurisdictions or corridor access points, we map those dependencies before the first field activity begins.
Owners usually benefit from early procurement checks on reinforcing steel, embeds, specialty concrete mixes, and any finish requirements that could change curing or turnover timing.
When a site stays active during construction, we also plan around access separation, safety controls, and the order in which areas can realistically be released back to operations.
Coordination That Protects Turnover
The strongest stormwater and drainage infrastructure deliveries in El Paso are the ones that account for owner operations long before the last punch walk. We keep closeout, access restoration, and documentation in view throughout the job so final turnover does not feel like a separate phase that starts after the work is already complete.

Stormwater and Drainage Infrastructure FAQs
We use El Paso Atlas 14 IDF curves for detention basin sizing — the 100-year, 1-hour rainfall intensity for El Paso is significantly higher than what standard TXDOT regional curves suggest, because the monsoon convective storm cells that produce El Paso's largest rainfall events are localized and intense in ways that regional frequency analysis underestimates. We design detention outfall structures for the 100-year storm volume and include an emergency overflow spillway for events that exceed the design capacity. Caliche-lined basins are evaluated as an alternative to imported geomembrane liner where the native caliche provides adequate low-permeability function — saving cost while maintaining TPDES permit compliance.
Concrete-lined arroya channels in El Paso County serve a different function than standard drainage swales — they must resist the high-velocity flow that occurs during monsoon storm events without erosion of the channel bottom or sidewalls. El Paso County Public Works specifies 3,500-psi minimum concrete for channel lining with a minimum 4-inch thickness on channel bottoms and 3-inch minimum on side slopes. We add a sulfate-resistant cement component when the soil report confirms high sulfate levels in the arroya banks, because slow ongoing leaching from arroya soils can attack standard concrete lining over time in alkaline desert environments.
Caliche creates two distinct installation challenges for stormwater infrastructure. First, utility trench production in caliche requires breaking equipment that significantly slows installation compared to normal alluvial soil — production rates for 24-inch storm pipe installation in hard caliche can be 40 to 60 percent lower than in typical Texas soil, which affects project cost and schedule if not accounted for in bidding and scheduling. Second, caliche's near-zero permeability during monsoon events means the perched water that accumulates above the hardpan can fill open stormwater structure excavations within hours of a rain event, requiring dewatering before concrete work can proceed. We maintain pumping equipment on site during July through September installation periods as standard practice.
