Corrugated Polypropylene Pipe Huffman — Sila by Lennar, TX

TDR Pipe supplied TDR PRO® corrugated polypropylene pipe in Huffman, Texas for the storm drainage system at Sila, a master-planned residential community developed by Lennar. TDR provided 24-inch through 42-inch pipe totaling 3,880 linear feet across the community’s distributed drainage network.

Project overview

Sila is a residential community in Huffman, Texas, developed by Lennar at 808 Prunella Lane. The project includes multiple single-family home collections—Wellton, Cottage, Watermill, Avante, and Bristol—with pricing from the low $100,000s to the mid $300,000s, supported by internal street networks and shared amenities. A community of this kind depends on drainage that protects streets, lots, and amenity spaces while staying invisible to homeowners. From the start, the stormwater system was planned to keep the neighborhood functional and dry as it grew phase by phase.

The Challenge: Layout-Driven Drainage Complexity

The community layout combines several home collections with varying lot sizes, setbacks, and landscape features, which created a complex drainage picture. Stormwater management had to accommodate runoff from multiple small drainage basins, residential streets, driveways, sidewalks, and amenity areas—all while maintaining lot usability and protecting future community features. Rather than a few large trunk lines, the site called for a distributed network that collects water close to where it falls, across many street segments and common areas, without sacrificing the buildable area homeowners expect.

The TDR PRO® Corrugated Polypropylene Pipe Solution

A distributed underground drainage approach was implemented to collect runoff close to its point of generation across street segments and common areas. Corrugated polypropylene TDR PRO® pipe was selected as the primary conveyance system to support consistent performance beneath residential streets with frequent driveway crossings and variable grading conditions. Pipe diameters were chosen based on incremental watershed size and street geometry, and gasketed joints were used throughout to maintain joint integrity and limit infiltration—supporting long-term hydraulic consistency under residential service conditions. The smooth interior keeps water moving on the low slopes typical of residential streets, while the corrugated profile carries driveway and roadway loads.

Phased Installation and Coordination

Drainage installation was sequenced to match phased development, starting with primary access roads and extending into secondary streets as plats advanced. Close coordination with grading, utilities, lighting, and paving reduced conflicts and allowed the stormwater infrastructure to be completed ahead of vertical home construction. Getting the buried network in early meant builders could move into home construction on dry, well-drained lots, keeping the overall schedule on track.

Results and Long-Term Value

The installed system effectively conveys runoff from streets and lot perimeters into designated collection points without surface flooding. Streets and common areas remain functional after rainfall, amenity spaces are protected, and maintenance exposure is reduced. The drainage system supports phased growth while preserving long-term residential value and usability—exactly what a master-planned community like Sila needs to deliver on its promise to homeowners over decades of use.

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.
