Project Descriptions
|
|
A sample of the planning and engineering projects completed
by David Venhuizen, P.E.
|
| |
| Hidalgo
County Colonias |
| 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. |
| |
| Washington
Island |
| 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. |
| |
| Quemado |
| Review of the facility plan conducted for
a wastewater system to serve Quemado, Texas, a colonia in Maverick County.
A full spectrum of options were explored, from individual on-site systems
to conventional, centralized systems. The cost effective solution in this
situation is a centralized plan employing "alternative" collection and treatment
technologies. |
| |
| Elysium |
| A residential and commercial development
in Austin, Texas, this project is served by a high performance biofiltration
treatment system, with system effluent running to a subsurface drip irrigation
system to water landscaping on the project site. |
| |
| TxDOT Rest Areas |
| Three systems have been designed for Safety
Rest Areas operated by the Texas Dept. of Transportation (TxDOT). These
systems utilize a high performance biofiltration treatment system and use
the effluent for irrigation of the rest area grounds. |
| |
| One-World Theatre |
|
A performing arts center on a rugged, environmentally
sensitive site employs a high performance biofiltration treatment system.
The effluent is pumped to drip irrigation fields on the project site.
|
| |
| Reynosa Maquilparque |
|
A study of installing a "waste" water system
focused on maximizing beneficial reuse of reclaimed water in a maquiladora
(border area industrial park) near Reynosa, Mexico.
|
| |
|
On-site "waste" water system for individual homes
|
|
Review of high performance biofiltration/drip
irrigation systems designed for single family homes in the Austin, Texas,
area.
|
| |
| El Salvador |
| A project funded by U.S. AID. A seminar
was conducted in San Salvador to acquaint Salvadoran, engineers, planners,
and regulators with the decentralized concept of wastewater management and
high performance biofiltration treatment technology. CARE El Salvador was
contracted as a partner to design and install a demonstration decentralized
concept system employing a high performance biofiltration treatment plant
in a small community. |
| |
| Winfield Township |
| A facility plan being conducted to compare
the costs and benefits of a decentralized concept wastewater system to a
conventional, centralized plan previously prepared for the township. |
