TDR PRO Corrugated Polypropylene Pipe Synova, Crosby, TX

Corrugated Polypropylene Pipe Crosby — Synova Community, TX

TDR Pipe supplied TDR PRO® corrugated polypropylene pipe in Crosby, Texas for the storm drainage system at Synova, a large residential community by Lennar with multiple home collections and shared amenities. TDR provided 24-inch through 48-inch pipe totaling 3,160 linear feet across a distributed, phase-ready drainage network.

Project overview

Synova is a large residential community in Crosby, Texas, featuring multiple home collections and shared amenities including parks, trails, lakes, and green corridors. In a community where open space and pedestrian areas are central to the experience, drainage had to protect usable open space and keep streets and paths functional—without relying on oversized surface fixes that would intrude on the landscape. From the start, the stormwater system was designed to stay out of sight while keeping the community dry.

The Challenge: Changing Runoff Across Phases
The site features gently rolling terrain with runoff behavior that changes as each phase adds roofs and pavement. Multiple localized low points increased ponding risk near lots, intersections, and pedestrian corridors. On top of that, each phase had to work independently from day one, maintain access during construction, and preserve grading around trails and water features—while leaving clean tie-in points for future phases. The drainage system had to perform on low slopes and adapt as impervious cover grew.

The TDR PRO® Corrugated Polypropylene Pipe Solution
Runoff was controlled through frequent capture and underground routing, reducing surface exposure in high-visibility areas like sidewalks, trail crossings, and amenity edges. Primary conveyance used dual-wall TDR PRO® corrugated polypropylene pipe, with smooth interior walls for efficient low-slope flow and gasketed joints to maintain continuity and limit infiltration. The smooth bore keeps water moving on minimal grades typical of residential streets, while the corrugated exterior carries roadway and driveway loads—protecting the parks, trails, and lakeside corridors that define the community.

Phased Sequencing
Main storm lines were installed early with grading and street base work, then extended with each neighborhood release to avoid rework around finished paving and landscaping. Building the drainage backbone first in each phase meant crews could move into vertical construction on dry, stable ground, and later phases could connect without disturbing completed sections.

Results
Rain events drained without persistent ponding on streets, lots, or pedestrian routes, reducing early maintenance and supporting a smoother phased buildout. For residents, that translates into dry streets and usable amenity spaces after storms; for the developer, it means dependable performance and lower long-term maintenance as Synova continues to grow.

About TDR PRO® Corrugated Polypropylene Pipe
TDR PRO® is a dual-wall corrugated polypropylene (PP) pipe engineered for gravity-flow stormwater drainage. It combines a smooth interior liner for hydraulic efficiency with a reinforced, annular corrugated exterior and a co-extruded integrated bell for watertight joints. Available in 12-inch through 60-inch diameters, TDR PRO® meets ASTM F2881 Class I and AASHTO M330 Type S, with watertight joints tested per ASTM D3212—making it well suited to residential, commercial, and infrastructure drainage projects across Texas.
