The pods and the seeds sound like something one would find on a shrub from the Family Fabaceae (Pea Family).   Since it is around the pool area and most likely put there by a landscaping company (maybe the one you work for) it is likely a non-native cultivar.   Our focus and expertise here at the Wildflower Center are with plants native to North America so we can't tell you a lot about non-native cultivars, but I will see what I can find that might be native and produce red seeds.  One native member of the Pea Family that has red seeds is  Sophora secundiflora (Texas mountain laurel), but that is obviously NOT what you saw since it has purple flowers.  Another native member of the Pea Family with red seeds, Erythrina herbacea (Coralbean), not only has red seeds but red flowers.

To try to find a native plant with seeds and flowers that match your description, I did a search in our Native Plant Database by choosing "Fabaceae (Pea Family)" from the Family slot.   When the list of over 400 plants appeared I used the NARROW YOUR SEARCH option to choose "Texas" from the Select State or Province slot, "Shrub" from the General Appearance slot and "White" from Bloom Color.  The only shrub that resembled the one you described is Eysenhardtia texana (Texas kidneywood).  Here is a link to a photo of its seeds.

You can see photos of selected seeds of Fabaceae on the Seed ID Workshop from Ohio State University.

If you have a photo of the bush and its flowers, you can visit our Plant Identification page to find links to plant identification forums that will accept photos of plants for identification.
