Agenda Item
Resolution - Water Utilities: Consider a resolution authorizing the Mayor to execute Professional Services Agreement 15688, with HDR Engineering, Inc., for a wastewater land application closure evaluation.
Item Summary
An important long-term strategic water supply goal of the City of Lubbock, is to use its treated wastewater for the most beneficial purposes, including eventual direct or indirect potable reuse. The City currently sends its treated wastewater to the Brazos River, the Xcel Jones Power Plant, the Lubbock Land Application Site (LLAS), and the Hancock Land Application Site (HLAS). The City has utilized treated wastewater effluent for irrigation at the LLAS since, at least, the 1930s. As early as 1968, the City became aware of a water table mound beneath the LLAS. This groundwater also contained high levels of nitrate nitrogen. In the 1970s, the City began pumping groundwater from the water table mound into the Jim Bertram Lake System (JBLS) as part of a remediation program. The remediation program was formalized in the late 1980s in response to an Agreed Order between the City and the Texas Commission on Environmental Quality (TCEQ). In 2009, the Agreed Order was closed, and the requirements became part of the Southeast Water Reclamation Plant (SEWRP) operating permit. 

In addition, over the past 15 years, the City has completed major upgrades to the SEWRP, including biological nutrient removal (BNR) at Plant 4, so the treated wastewater can be discharged into the Brazos River. The long-term goal of these upgrades is to prepare for potable reuse in the future. The City has plans to upgrade Plant 3 over the next ten years, so that 100% of the treated wastewater being discharged from the SEWRP is stream quality. The City is also seeking to use its treated wastewater for intermediate beneficial purposes that generate revenue, until the treated wastewater can be reused for drinking water. As the City transitions to stream quality discharge and other beneficial uses of the treated wastewater, it will become less reliant on land application of the effluent.

This contract with HDR will assist the Water Utilities staff in determining the best approach to reducing the use of, and reliance on, land application methods as a way of managing treated wastewater in the future. It will also help staff ensure that LLAS and HLAS are kept in compliance with current regulations and permits. This project will include quantifying the financial benefit associated with various land application reduction options. Reduction and/or elimination of land application as a disposal/reuse option may significantly reduce the annual wastewater operating budget.
Fiscal Impact
$300,000 is appropriated in Capital Improvement Project 8654, Land Application Closure Evaluation, with $249,400 available for this project.
