Biography

Dr. Hoeksema is a Civil Engineer with interests in hydraulics, hydrology, and water resources. He has done research applying geostatistical techniques to estimation problems in the subsurface. This work has been done for Oak Ridge National Laboratory and the Netherlands Institute of Applied Geosciences - TNO. He has also taught short courses in applied geostatistics for the International Groundwater Modeling Center (located at the Colorado School of Mines). He currently provides professional services for Fishbeck, Thompson, Carr and Huber, Inc.

Research and Scholarship

ecuador

Water Disinfection in Ecuador

THE CHALLENGE

Diverse georgraphy and cultural practices

WHAT WE DO
  1. Evaluate delivery systems (chemical and feed) and determine best practices and critical success factors.
  2. Evaluate water chemistry and provide field testing methods.
  3. Test water system dynamics for proper levels of disinfectant residual.
  4. Evaluate palatability—the taste/odor-based rejection threshold for disinfected water.
ACADEMIC DISCIPLINES:
OUR PARTNERS
  • Lifegiving Water International
  • CODEINSE
  • Ecuadorian regional governments (Cantons, Guamote, Colta) responsible for about 400 communities
THE IMPACT
  • Household
  • Local
  • Regional
  • Global

Reactivation of Ancient Water Delivery System in Jordan

The challenge

Waves of refugees straining an already water-starved environment

What we do
  1. Evaluate the system's surface water supply. This involves delineating the water basin, assessing the quality of the water, hydrologic modeling, and flooding mitigation.
  2. Assess current conditions of the system through mapping and hydrologic and hydraulic modeling.
  3. Evaluate the system's future operation — its adequacy to respond to the demand for water in surrounding communities. This involves designing options for the repurposed system, providing optimized capacity with minimized archeological compromise.

curahuasi

Drinking Water Distribution and Disinfection Improvements for Curahuasi, Peru

Curahuasi’s current distribution system is fed from natural springs located in the mountainside above the municipality. Due to the large vertical drop from the water source to end use, the distribution network experiences very high system pressures. This has required water shutoffs and inconvenience to the citizens of Curahuasi, due to the poor quality of their water system.

Calvin students, under the supervision of David Wunder and Robert Hoekema, have designed a much more efficient system with additional reservoirs to deal with the pressure issues.
