Resolution - Wastewater:
Consider a resolution authorizing the Mayor to execute Professional Services Agreement, Contract 17008, with Agri-Waste Technology, for water/nitrogen balance modeling and cropping consulting, related to the Lubbock Land Application Site and Hancock Land Application Site.
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 complies 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 semi-annual consultant site visits, to verify that conditions at LLAS and HLAS are consistent with TCEQ requirements. The model assists staff in ensuring that the land application activities do not add additional nitrate to the groundwater. Additionally, the model provides recommendations on crop rotation schedules to ensure that the high nitrate effluent water is balanced with the ability of the crops to use the nitrate in the water, preventing nitrate from migrating 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 $359,900.
Fiscal Impact
Sufficient funds of $359,900 have been allocated in the FY 2022-23 Water/Wastewater Fund Operating Budget for this contract..
