Geodesic Dome For Water & Wastewater Tanks

Water Wastewater Dome Cover




“We are extremely pleased with the HMT aluminum cover - quality workmanship that exceeded our expectations. The best structural aluminum cover we have seen.” Clay Watson, Environmental Engineer - GNP Company

HMT’s Geodesic Dome Roofs are custom-engineered to accommodate a wide range of shapes, spans and operating service conditions. They are designed with guidance from the latest revision of AWWA D108 or API 650, Appendix G.

The HMT Geodesic Dome Roof is made of Aluminum and offers multiple advantages over concrete, fiberglass, or steel cover alternatives. HMT’s Geodesic Dome roof can be designed to accommodate various special loading and design conditions, specifications and requirements. Applications include water storage, wastewater treatment, clarifiers, thickeners, basins, reservoirs and other cover considerations.

HMT’s state of the art design program fully integrates three dimensional design with finite element analysis. In real-time, this program generates customer drawings, CNC fabrication drawings, structural analysis reports and a bill of materials; this cutting-edge system ensures fast, accurate design and allows the design engineer to optimize the efficiency of the complete structure.

The HMT Geodesic Dome Roof is ideal for both new tank construction and tank retrofit projects. HMT Domes are fabricated from high strength, corrosion resistant aluminum alloy materials that resist chemical, UV and ozone degradation. The structure is designed to be clear span and self-supporting from the tank shell, eliminating the need for internal supports.

The unique HMT design prevents the intrusion of rainwater, eliminating the possibility of stored product contamination. Noxious odors are significantly reduced, as wind-induced vapor is eliminated. All gasketing is completely protected from UV and ozone attack and all seams are protected by primary and secondary seals.

As with all HMT products and services, experienced HMT field crews are available for fast, efficient installation. The HMT design allows for installation to be performed in-service, out-of-service or on new tanks.
