Rainwater team working on cleaning and reconstructing the roof

The Practivistas Domincana Program is currently a study abroad program involving Cal Poly Humboldt and UNIBE that takes place in Santo Domingo, Domincan Republic. The rainwater catchment system in Las Malvinas in Santo Domingo was first constructed in 2011 by Intelegencia Colectivo from UNIBE. The water from this system was used for washing but was not potable.

Objective[edit | edit source]

Vandalism and two years of wear and tear has caused the system to fail in its purpose to collect rainwater. The goal is to return the system to working condition and to improve on the previous design.

Literature Review[edit | edit source]

Literature reviews from La Yuca rainwater catchment (2013) (2012) (2011) were utilized to understand and reconstruct the rainwater catchment system in Las Malvinas.

Criteria[edit | edit source]

Criteria Constraints Weight
Accessibility Convenient location for everything 8
Level of Maintenance Necessary < 3X a year 8
Water Demand enough to wash clothes for a few families 8- depends on rain
Educational at least 1 person 7
Safety Must be sturdy and clean enough for washing 9
Time finish project before we leave 10
Materials Materials are all local 8
Cost as inexpensive as safely possible 8
Durability Long lasting design 8

Final Design[edit | edit source]

The final design of the rainwater catchment system in Las Malvinas consisted of reconstruction of the roof and first flush. Additionally a primary screening and PVC gutters were included in the design. The outcome consisted of a working rainwater catchment system that efficiently prevents contaminants from entering the tinaco(water storage tank).

Maintenance[edit | edit source]

This final design requires consistent upkeep in order to reduce the amount of contaminants. Periodically OR Every Few Rainfalls

  • First Flush holes should be cleared of any blockage

Every Month

  • Primary screening must be checked for damage or clogging

Every Year

  • First Flush must be thoroughly cleaned
  • Tinaco (or storage tank) must be emptied of sediment and disinfected
  • Sediment must be replaced

Maintenance Video[edit | edit source]

Refer to the La Yuca rainwater catchment 2013 maintenance video for guidance on how upkeep a rainwater catchment system.
