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.

42-inch Water Line Design, Segment 3 A1

42-inch Water Line Design, Segment 3 A1 Harris County, Texas DCCM provided final design and construction phase services for 14,000 linear feet of 42-inch water transmission line within a CenterPoint Energy electric transmission line corridor and easement. This water line is part of the West Harris County Regional Water Authority’s (WHCRWA) 2025 system, which will meet at least 60% of water demand with surface water. This is the latest project in a long history of working with WHCRWA to supply their surface water requirements. The project involved installing water lines in CenterPoint Energy’s electrical transmission line corridor for miles. Trenchless construction was required within 20 feet of truss towers and across busy roadways. Close coordination was maintained with the City of Houston and Harris County for permitting and the acquisition of record drawings. Collaboration with the design engineer ensured a proper connection to an 84-inch water line. Additionally, coordination with multiple petroleum pipelines and dry utilities in CenterPoint Energy’s corridor was necessary.

Wheatland Wastewater Improvements

Wheatland Wastewater Improvements Wheatland, IN DCCM led an internal and external team of engineers to design and develop a new sanitary sewer system for the Town of Wheatland. This system included designing three positive displacement blowers for a new extended aeration plant along with several miles of new low pressure force main, one lift station, and a package wastewater treatment plant for the town of 500 people. The team evaluated wastewater lagoons for Wheatland being crucial for maintaining compliance with regulations and ensuring effective treatment. One of the key challenges in the design of project was ensuring the project met the Town’s limited budget, supported by a $14M SRF grant award for water/wastewater. Through a combination of creative design and funding solutions and selection of a minimally invasive technology such as low pressure sewer, DCCM was able to secure reasonable bids that allowed the project to proceed. At a Glance 10 Miles $10.2M Project Cost “The team (DCCM) is nothing short of amazing on the projects we have worked on with them. They are always organized and available if there are questions. I have seen Aaron Crow, Poject Manager, work along with his team members as he is always clear and concise on what he is asking for. I believe the team excels under his leadership and never feel overwhelmed or worried about the projects because they communicate with us to keep everyone organized and on task. They have definitely been an asset to our Town and Utility!” Erika Goble Wheatland Deputy Clerk Markets Municipal Water Services water Conveyance Treatment Water Resources
