Agenda Item
Resolution - Water Utilities: Consider a resolution authorizing the Mayor to execute Professional Services Contract 15570 with Agri-Waste Technology for water/nitrogen balance modeling, and cropping consulting related to the Lubbock and Hancock Land Application Sites.
Item Summary
The City must continuously monitor soil conditions and crop efficiencies at the Lubbock Land Application Site (LLAS) and Hancock Land Application Site (HLAS) to ensure that the City is in compliance with the Southeast Water Reclamation Plant’s (SEWRP) wastewater discharge permit authorized by the Texas Commission on Environmental Quality (TCEQ).  Treated wastewater irrigation optimization requires agronomy and engineering consulting services, to monitor site conditions and periodically update water and nitrogen balance models related to land application activities. 

This contract for consulting services provides water/nitrogen balance modeling, including an annual model update and 2 site visits to verify that conditions at LLAS aand HLAS are consistent with TCEQ requirements. The model assists staff in ensuring that the land application activities do not add additional nitrates to the groundwater. Additionally, the model provides recommendations on crop rotation schedules to ensure that the high nitrate effluent water is balanced with the crops' ability to use the nitrates in the water, preventing them from filtering down through the soils into the groundwater.

Staff recommends that this contract be executed with Agri-Waste Technology of Apex, North Carolina, based on their demonstrated competence and qualifications.  The contract term is for up to 2 years and the fees for services shall not exceed $339,670.
Fiscal Impact
The FY 2020-21 Water/Wastewater Fund Operating Budget has sufficient funds of $339,670 available for this project.
