Facing challenges in storing enough water to support community growth, Green Valley Special Utility District (GVSUD) prioritized several critical infrastructure projects to increase water storage capacity. In collaboration with GVSUD, Trihydro secured United States Department of Agriculture (USDA) loans exceeding $16,000,000 to fund three proactive system improvement projects, including a water transmission line, two elevated storage tanks, and a sanitary sewer capacity buy-in.
Trihydro initially worked with GVSUD to secure project funding under the USDA Water and Waste Disposal Loan and Grant Program. The process involved creating the funding application, preparing a Preliminary Engineering Report (PER) and an environmental report, and coordinating with the USDA. The PER included an assessment of existing facilities, evaluations for project need, and an alternative analysis. The environmental report detailed land use, historic preservation, endangered wildlife, and impacts on local waters.
Following the submission and acceptance of the PER and environmental report, Trihydro designed approximately 16,000 feet of 24-inch transmission line and two 1-million-gallon elevated storage tanks. The transmission line design included multiple wetland crossings and higher system pressures while maintaining compliance with Rural Utilities Service and American Iron and Steel (AIS) requirements. The storage tanks created additional elevated storage for current residents and future growth to stay within compliance with Texas Commission on Environmental Quality (TCEQ) requirements and to provide water for fire flow.
Finally, Trihydro bid the projects and performed construction administration and observation to confirm conformance to the plans and AIS requirements. Trihydro also coordinated pay applications and contract changes through the USDA and documented compliance with federal regulations.
