and their ecology.

ABOUT

MISSION STATEMENT

The Urban Watersheds Research Institute (Institute) is a Colorado based 501(3)(c) non-profit corporation created in 2005.  It is dedicated to the sustainable environment and water resources of urbanized and urbanizing communities.  Our focus is on water resources technology, its development and its transfer to practitioners and public in order to benefit the urban watersheds ecologies. The Institute is also a licensed State of Colorado charity, eligible for not only Federal tax exempt donations but also by the State of Colorado. The Institute focuses on achieving its goals through:

promoting research

conducting seminars, technical training classes and workshops

participating and helping to organize conferences

participating in various urban water resource related activities

 

Topics of most immediate concern to the Institute include:

Urban water resources,

Storm water system modeling technology,

Storm water quality and quantity management and design,

Floodplain management and flood damage mitigation,

Restoration of degraded rivers, streams, lakes and other receiving waters,

Urban ecology protection,

Community needs, including aesthetics and function,

Long-term economic sustainability.

 

We ask for your support of our mission by sharing your thoughts and ideas with us, attending our sponsored classes/seminars/workshops and other events.  We also appreciate any financial contributions you make to this Institute to help us pursue these goals.

Most of these classes are sponsored in part by the Urban Drainage and Flood Control District which allows the Institute to reduce the registration fee for them.  In addition, member of the Colorado Association of Stormwater and Floodplain Managers (CASFM) and of the Rocky Mountains American Public Works Chapter (RM-APWA) receive an additional discount. Most classes, unless otherwise noted on the individual class description, in 2017 are held at the training facility of Leonard Rice Engineers, Inc. in Denver. Significant additional discounts are available for early registrations. In addtion, for all classes related to water distribution system, members of AWWA receive a sifnifican discount. 

For detailed information about each class just click on the class name which will take you to website containing full a description.

Refund Policy: Full refund will be made if class is canceled by the Institute. Full refund will be given, less an admistrative handling fee, if requested by the student more than 10 days before start of class. No refund will be given if requested by student 10, or fewer days before start of class. There is no time restriction to substitute another student for the one originally registered. The Institute is not responsible for any other costs.

RESEARCH

Since 2005 the Institute has conducted and promoted research in support of finding sustainable stormwater runoff management practices.  Many of these have been done in partnership with the Urban Drainage and Flood Control District (UDFCD), a special regional government covering the Denver metropolitan and adjacent areas. The following is a list of most of these efforts:

 

  1. A $10,000 grant to UDFCD to help fund a $97,000 effort to develop whole life-cycle effectiveness of stormwater BMP's. The work is being performed by Colorado State University under an agreement with the District. Colorado State University is using the total amount of the funds as one of the local matches for a major research project funded by the Water Environment Research Foundation.
  2. A $10,000 grant to UDFCD to help fund a Phase I of a research project by University of Colorado Denver to determine what can be mixed with sand and in what proportions to produce more affordable plant growth media for rain gardens (bio-retention cells, porous landscape detention) that will sustain robust plant growth, maintain high stormwater infiltration rates and provide good water quality treatment. Emphasis is on materials that may come from urban waste streams such as high quality compost, shredded paper, etc.
  3. A $10,000 grant to UDFCD to help fund Phase II of the research project by the University of Colorado Denver described above. This phase begins to extend the research work to field installations.
  4. A $10,000 grant to UDFCD to fund phase III of the research project by University of Colorado Denver described above. This phase extends the field investigations.
  5. The Institute entered into agreement in 2011 with to UDFCD to contribute $15,000 towards research project to study on-site runoff storage for landscape irrigation use by property owner. The District will match this contribution and expects to increase its share in 2012. The study will investigate the performance, needs and economics of capturing runoff from building roofs for reuse as lawn sprinkling water in a semi-arid climate.
  6. With help and input from UDFCD, the Insitute develoedp a continuous simulation model to estimate water quality capture volume for the sizing of stormwater runoff BMP and LID facilities. In 2017 it released an updated version of the model.  
  7. The Institute continues to develop design and analysis aids for engineers to manage stormwater runoff and its impacts.  In addition, the Institute has used the whole-life effectiveness software and the BMP/LID sizing software to analyze the effectiveness, economics and whole-life costs of implementing various options for managing stormwater runoff in several regions of United States.
  8. In 2014 partnered with UDFCD to fund the completion of a Pathogens in Stormwater report by the Urban Water Resources Council of the Environment and Water Resources Institute of ASCE. This funding permitted the completion of this very state-of-the-practice report that was in progress for several years and is now available through ASCE.

SCHOLARSHIPS

Between 2005 and 2008 the Urban Watersheds Research Institute has provided each year two $2,000 college scholarships to undergraduate engineering students at accredited Colorado Universities and between 2009 and 2012 two $2,500 scholarships. These were awarded through the Stormwater and Floodplain Managers’ (CASFM) and the American Public Works Association (APWA), Colorado Chapter’s scholarship committees. The awarding of these scholarships has been temporarily suspended due to other demands on the Institute’s fiscal resources.
