ITEM: AUTHORIZATION TO AWARD A TASK ORDER TO PROVIDE HYDROGEOLOGIC CONSULTING SERVICES FOR GROUNDWATER MODELING SERVICES

EXPLANATION: On January 29, 2016, Council awarded an engineering services contract (004-17/DZ) to multiple vendors. As part of the solicitation, JLA Geosciences, Inc. was selected as one of Wellington's engineering service providers. Staff is seeking authorization to utilize such contract with JLA Geosciences, Inc. to provide hydrogeologic consulting services.
The Utility uses ground water from surficial wells to supply raw water to the water treatment plants. The South Florida Water Management District (SFWMD) regulates water supply in our area and issued a Consumptive Use Permit to the Village in 2011. The Utility is currently using approximately 85% of its annual permitted allocation. An increase in the annual allocation is necessary to support existing plant capacity, accommodate future growth in the Royal Palm Service Area and accommodate redevelopment and infill within Wellington. The future replacement of the existing Lime Softening Plant with a membrane plant also increases supply needs due to the fact that membrane plants require more raw water to address reduced treatment recovery ratios.
In order to obtain an additional allocation, a permit modification is required. In order to demonstrate that the additional allocation meets the SFWMD Regional Availability Rule, a groundwater model is required. The proposed scope of work includes developing a calibrated MODFLOW groundwater model to simulate the surficial aquifer system in Wellington and analyze the effects of additional withdrawals and surface recharge scenarios.
