Desert Color is a new sustainable master-planned community in St. George, UT developed by Desert Color partnership team. The Desert Color community includes a 2.4-acre and 4-million-gallon man-made lagoon surrounded by residential and short-term rental units where residents and rental guests can enjoy the open waters of the lagoon night and day. PACE was the engineer-of-record for the man-made lagoon system. The programming of the lagoon includes 3 sand beach entries and shallow chaise lounges that surround an open body of turquoise blue water designed for recreational water activities year-round. Construction of the lagoon included seamed panels of RPE textured white liner that lines the entire footprint of the lagoon floor and precast concrete walls. The body of water is treated through a recirculation system of commercial pool sand filters, an onsite ozone generation system, and a chlorine/acid feed injection system. The body of water has a 10-hour turnover rate at the deeper bodies of water and a 4-hour turnover rate at the shallower high-traffic beach entries. Underwater pool LED lights were installed in the lagoon walls and designed to illuminate different holiday and party-mode themes of the year.
