The Northside Independent School District (NISD) was looking to construct a second Aquatics Center at the Ferris Athletic Center on Loop 1604 W located in San Antonio, Texas. This outdoor aquatic center could be utilized, along with their indoor facility adjacent to it, as a venue to host future swim meets, including future Olympic trial meets. Since the project site was located over the Edward’s Aquifer, the rainwater that was being captured on the newly constructed impervious cover was required to be treated prior to discharging into the nearest creek, and eventually into the aquifer

The design engineer reached out to Contech to utilize a Variable Height Slotted Drain™ System to capture all of the stormwater runoff via an efficient sheet flow capturing process. The captured stormwater would then be piped to two Vortech® stormwater treatment units, also manufactured by Contech Engineered Solutions. The Vortechs units were utilized to remove 80% of the TSS (Total Suspended Solids) from the stormwater captured per the TCEQ regulations.

As the design engineers were trying to keep the finished grade relatively flat surrounding the aquatic complex, Contech’s Variable Height Slotted Drain™ proved to be the right solution for this scenario. The variation of the slot height allowed the pipe to have the necessary fall it needed, while keeping the finished grade at a constant elevation. The Variable Height Slotted Drain could also be installed on a radius curve, as it was located just inside of the segmental block retaining walls.

Cude Engineers has a long history of utilizing Contech drainage materials and were confident in specifying this proven solutions. The products specified by Cude Engineers were chosen because they were the best materials for these particular application.

The project, from beginning to end, was a huge success, and the materials were utilized exactly how they were designed. Contech representatives have even had the pleasure of personally attending several swimming events at this NISD Swim Center. It is a first class facility!
