Jeff DenBleyker

Project Manager and Water Resources Engineer



Jeff has worked extensively with Great Salt Lake stakeholders since 2004 to investigate some of the Lake’s most acute challenges and develop and implement collaborative solutions. He has helped craft and implement strategies to develop selenium and nutrient water quality standards for Great Salt Lake, investigate and better understand the hydrology of Great Salt Lake’s shoreline, develop the GSL Integrated Model to understand how future changes in Great Salt Lake’s watershed might affect Great Salt Lake, and shape a new Great Salt Lake salinity advisory committee.

Title: An Innovative Approach to Meet Discharge Limits

Abstract: North Davis Sewer District (NDSD) initiated the development of a Nutrient Management Master Plan study in 2017 to define an effective and efficient strategy to meet a new technology based phosphorus effluent limit (TBPEL) and other future potential regulatory requirements. NDSD’s initial planning identified a new Water Reclamation Facility as a means to meet current and anticipated new site-specific nutrient water quality criteria, possible phosphorus total maximum daily loads (TMDL) and/or potential new, more stringent statewide technology based effluent limits intended to protect the water quality of Farmington Bay and Great Salt Lake. 

NDSD planners also determined that enhanced effluent water quality in combination with increasing demand for water resources will likely lead to reuse of the effluent for secondary or even primary drinking water uses. Although reuse would eliminate all of NDSD’s nutrient load to Farmington Bay, it may also eliminate the Water Reclamation Facility’s effluent altogether from Farmington Bay and Great Salt Lake. A reduction of inflows to Great Salt Lake could then further exacerbate already observed detrimental changes to Great Salt Lake’s ecosystem due to declining water levels, such as water quality, shoreline habitat, exposed mudflats, Gilbert Bay nutrient levels, etc., – all inconsistent with the objectives of NDSD and Great Salt Lake’s stakeholders. Thus, NDSD decided to work with the Division of Water Quality and Great Salt Lake stakeholders to investigate alternatives to meeting the TBPEL that both meet water quality regulations and increase the probability of maintaining its flow into Great Salt Lake. This presentation will summarize the collaborative process used to develop the final solution. 


Why We Care

  • Somewhere there should be a place for artists and tourists—if no one else is interested—to watch the gulls wheel into a flaming sunset and to ripple their hands in the smooth brine.
