Corrugated Polypropylene Pipe Richmond — Still Creek Ranch, TX

TDR Pipe supplied TDR PRO® corrugated polypropylene pipe in Richmond, Texas for the storm drainage system at Still Creek Ranch, a residential development shaped by the site’s natural landform. TDR provided 24-inch through 60-inch pipe totaling 3,260 linear feet across an adaptive, contour-following drainage network.

Project overview

Still Creek Ranch is a residential development in Richmond, Texas, shaped by existing landform and drainage features rather than imposed geometry. Homes, parks, and open corridors were planned around natural grades and creek-adjacent areas, which meant the stormwater infrastructure had to complement the site’s inherent flow tendencies instead of fighting them. From the start, the drainage system was designed to work with the land—routing water the way it already wants to move while protecting the trails, parks, and creek-side amenities that give the community its character.

The Challenge: Irregular Flow Behavior

Elevation shifts, vegetated swales, and natural drainage paths created multiple directional runoff patterns across the site. These conditions ruled out a uniform grid or single-main approach and required stormwater solutions that could respond to localized flow behavior without excessive grading or disruption to amenity spaces. The network had to intercept water where it naturally concentrates, navigate around sensitive landscape features, and stay reliable across varying soil and moisture conditions.

The TDR PRO® Corrugated Polypropylene Pipe Solution

Stormwater control was achieved through a flexible subsurface network designed to intercept runoff where it naturally concentrates and convey it downstream incrementally. TDR PRO® corrugated polypropylene pipe was used to navigate around trails, green corridors, and park boundaries while maintaining consistent hydraulic performance beneath residential streets. Pipe sizing was driven by site-specific runoff characteristics rather than standard spacing—smaller diameters at lot edges, walkways, and pocket parks; mid-range sizes for residential street drainage; and larger lines where tributary flows combined. Gasketed joints provided continuity and controlled infiltration across varying soil and moisture conditions, while the smooth interior sustained flow on natural grades and the corrugated profile carried roadway loads.

Sectional Buildout Coordination

Drainage construction followed neighborhood progression instead of full-site installation. Primary lines were placed early to establish flow control, with secondary and lateral connections installed alongside street base preparation. Final connections were completed ahead of paving to protect finished landscaping and minimize disruption. This sectional approach kept the build moving while preserving the green spaces already in place.

Results and Market Impact

Early-phase rainfall events showed even street drainage, dry intersections, and rapid recovery of landscaped areas. No re-grading or inlet modifications were required, indicating a balanced system response across multiple flow paths rather than isolated runs. Stormwater did not become a recurring construction issue, preserving schedule momentum, and buyer feedback consistently noted that the neighborhood remained “dry” after rain—reinforcing perceived quality and long-term value without visible infrastructure intervention.

Operational Results and Market Effect

Drainage construction followed neighborhood progression instead of full-site installation. Primary lines were placed early to establish flow control, with secondary and lateral connections installed alongside street base preparation. Final connections were completed ahead of paving to protect finished landscaping and minimize disruption. This sectional approach kept the build moving while preserving the green spaces already in place.

Operational Results and Market Effect

Following rainfall, surface areas drained evenly without standing water along streets, sidewalks, or common spaces. Landscaped zones remained stable with no signs of erosion or oversaturation, and the system required no post-installation modification to handle variable flow conditions. That consistent performance translated into visible quality for buyers: sales teams reported positive feedback tied to dry walkways and functional green spaces after storms, supporting absorption rates and reinforcing long-term neighborhood value.

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.
