We're dedicated to urban watersheds and their ecology.




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.

Water Systems Distribution Network Design & Analysis.


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.

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.

  9. In 2016 was a co-recipient with University of Texas (Lead grantee) of an EPA grant to perform research for the enhancement of EPA’s computer models SWMM and EPANET and to explore feasibility to develop crowdfunded support of those two models. This is a five-year grant. Significant progress is being made on upgrading code of SWMM that has a potential to increase it processing speed many fold and provide added features for the user community.
