Site work for a water / sewer project in Dallas, Texas. Completed plans call for site work for a water / sewer project.

REVISE the Anticipated Date for the Deadline for Questions Event in the schedule on page 3 from December 3, 2025 to December 12, 2025 The project scope includes the following major items: The construction of a fourth anaerobic digester tank with a reactor volume of 3 million gallons (3 MG) to provide additional digestion capacity, redundancy, and operating volume versus existing Digester Nos. 1, 2, and 3. A dedicated digester mixing system for proposed Digester No. 4 which will consist of an externally pumped, hydraulically mixed nozzle system that will mix the digester contents using hydraulic jets. A cooling heat exchanger to maintain optimum process temperatures for proposed Digester No. 4. The construction of a WAS Storage Tank (WASST) adjacent to the existing Pre-Dewatering and Thickening Building with a volume of 301,600 gallons to provide a control point between pumping WAS from the existing Final Clarifier Nos. 1-12 to the Gravity Belt Thickeners (GBTs). The WASST will convey flow to the GBTs via a GBT Feed Loop system which will include pumps, piping, supports, and associated hardware. A chemical feed building located near proposed Digester No. 4 to house an alkalinity feed system which will send flow to the existing Digested Sludge Storage Tank (DSST). Installation of Pre-Dewatering Centrifuge No. 6 along with all associated equipment, such as Centrifuge Feed Pump No. 6, Thickened Cake Pump No. 6, and Polymer Feed Pump No. 6. The construction of a DMX Reactor System and all associated subsystems to reduce the nutrient loads returned to the influent of the CRWS Treatment Plant. A Sidestream Treatment Building to house all the pumping equipment, electrical gear and miscellaneous items associated with the DMX Reactor System. Demolition of offline structures, such as Primary Clarifier Nos. 1 and 2 along with any associated yard piping, manholes, pull boxes, conduit, drainage systems and appurtenances. Installation of proposed yard piping, conduit, duct bank, drainage systems, general site improvements such as temporary erosion and sediment controls, grading and resurfacing, and paving. Estimate: $90M-$95M *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document.
