This page reviews the background and qualifications of David Venhuizen, P.E., and of a few projects he conceived and executed. Introduction to David Venhuizen, P.E. A brief review of Venhuizen’s work in the development and implementation of the decentralized concept of “waste” water management. Professional Vita of David Venhuizen, P.E. A review of Venhuizen’s education, licenses, major projects, and presentations. A listing of the planning and engineering services provided by David Venhuizen, P.E. Project Reviews Describes facility planning conducted for 26 colonias (subdivisions lacking adequate water and/or wastewater facilities) in Hidalgo County, Texas. The results show that decentralized management concepts can produce wastewater systems costing less than half the cost of conventional, centralized strategies. The planning process for a wastewater management system on Washington Island, Wisconsin, is reviewed. Describes the demonstration project to confirm capability of a denitrifying sand filter concept to perform there and formulation of a decentralized management system for the island. (See also “A Texas Regulator’s Guide” in the “Biofiltration Technology” menu.) Elysium Residential/Commercial Condominium Describes the design of a wastewater system utilizing effluent sewerage, a high performance biofiltration treatment unit and a subsurface drip irrigation dispersal system to serve a project with 5 homes and two small commercial buildings. Describes the design of wastewater systems for two Texas Department of Transportion Interstate Highway Safety Rest Areas, utilizing high performance treatment units and subsurface drip irrigation dispersal areas, which irrigate a large portion of the rest area grounds. CARE-El Salvador – Village Wastewater System Reviews the planning and design, conducted in conjunction with CARE-El Salvador under U.S. AID funding, of a decentralized concept wastewater system for a portion of a village lying in a separate drainage basin from the rest of the village. The system consisted of an effluent sewerage system – the lines of which had to be integrated into the tight constraints imposed by the existing development, a dual treatment unit – demonstrating both high performance biofiltration and constructed wetlands, and a reuse project – in which the village residents used the effluent to grow standing food crops and ornamental plants for sale. Bluff, Utah, Wastewater Facility Plan Describes the decentralized concept strategies that were considered to create a service plan, taking into account the particular challenges in the context of this community. Santuario de Chimayo Wastewater Treatment Unit Describes the design of a high performance treatment unit to meet the challenges of the largest Catholic pilgrimage site in the western hemisphere, in particular seasonal peaking of wastewater flow, most critically a huge peak during Holy Week. |
