Lake June Phase 1 – Pump Station

June Lake Phase 1 – Pump Station Spring Hill, Tennessee June Lake is a premiere mixed-use development located on nearly 800-acres at the gateway to the City of Spring Hill, Tennessee. Located adjacent to I-65, June Lake is fully entitled for 2,900 homes, 3.9 million SF of commercial office space, 1.3 million SF of retail and restaurant space, and 400 hotel rooms. DCCM was contracted to design and permit the water and sewer infrastructure for the development, including the Phase 1 sanitary sewer lift station. The lift station was designed to manage a peak demand of 604 gpm, with a total dynamic head (TDH) of 70.2 ft. The design was complicated by the force main having to overcome two separate high points. Ultimately, a steady-state analysis determined that the water column within the force main would start to separate at Station 14+00 and become gravity flow at Station 14+40. The lift station has a 10-ft diameter wet well and utilizes duplex 50-horsepower suction-lift Gorman-Rupp pumps. The station is equipped with an emergency bypass quick-connect fitting and valving that allows City maintenance equipment to continue to manage the demand if the pumps are offline. Services included survey, engineering design, permitting, and construction administration. At a Glance $85,000 Design Cost Markets Water Surveying Services Water & Wastewater Surveying

IH 45 and SH 6 Water Distribution System Improvements

IH 45 and SH 6 Water Distribution System Improvements Galveston County, Texas DCCM provided preliminary and final design and construction-phase services for 8,100 linear feet of 24-inch water line as part of a collaboration between the Galveston County Water Authority and Galveston County to provide potable water to a future residential area in Texas City. To accommodate this needed water line, an alignment was established at the intersection of Avenue L and a Galveston County Water Authority canal in Santa Fe, where the line connected to an existing water line and then extended along the north high bank of the canal to a metering station site west of IH 45. This project was funded by the State of Texas through a Community Development Block Grant and administered by the Texas General Land Office due to damage from Hurricane Ike. The funding was allocated to Galveston County, thereby funding the construction and managing the design and construction phases.

Countryside Wastewater Treatment Plant Decommission, Lift Station and Force Main Upgrade

Countryside Wastewater Treatment Plant Decommission, Lift Station and Force Main Upgrade League City, Texas DCCM was selected to provide preliminary engineering, final design, and construction services to decommission the existing Countryside Wastewater Treatment Plant (WWTP) and install a new lift station and new force main to divert wastewater to the existing Southwest Water Reclamation Facility. The existing lift station was decommissioned and replaced with a new 10-foot lift station featuring three 20-horsepower submersible pumps, providing a firm capacity of 850 gallons per minute for diversion service. The design included modifications to the existing sewer collection system, including the addition of new manholes and gravity lines to intercept and divert sewer flow to the new lift station. Construction sequencing, bypass pumping, and coordination were carefully planned to allow the construction of the new lift station, sewer diversion, and demolition of the existing lift station and wastewater treatment facilities. The new lift station featured a programmable logic controller (PLC)-based pump control panel, supervisory control and data acquisition (SCADA) access via a wireless antenna for remote monitoring, and a manual transfer switch to facilitate emergency generator connection in accordance with TCEQ requirements.

108-Inch Northeast Transmission Line, Contract 99D-2

108-Inch Northeast Transmission Line, Contract 99D-2 Houston, Texas DCCM provided final engineering design and construction-phase services for 1.4 miles of 108-inch water main from Aldine Westfield Road to Willis Street in north Houston. This project was extremely complex due to the size of the water main and the congested area where the alignment was located. DCCM worked with the City of Houston and its Program Manager to develop a 50-foot water line easement through an existing urban region. To develop the preferred alignment, DCCM considered construction issues, including laydown areas, environmental constraints, traffic impacts, and existing utilities. DCCM developed alignment alternatives, such as tunnels instead of open-cut construction, in multiple areas to minimize or eliminate significant impacts on existing businesses, as numerous commercial buildings are close to the route. Tunnels were designed to mitigate the impact on the buildings and their operations in these areas. Since the project was in an urban region, DCCM worked closely with the existing utilities to develop utility conflict documents and support their relocation. The design also included construction phasing and traffic control to maintain access to residences, facilities, and emergency services. The water line was a significant transmission main constructed via open-cut and tunneling methods. Each method was optimized for the project.
