Wisconsin Administrative Code › Department of Natural Resources › NR 800 - Environmental Protection - Water Supply › Chapter NR 811 - Requirements For The Operation And Design Of Community Water Systems › Subchapter XIII - Aquifer Storage Recovery › Section NR 811.93 - Operating an ASR system

Current through June 24, 2024
(1) Department
				  approval to operate an ASR system shall be obtained prior to recovery of any
				  water retrieved through an aquifer storage recovery well into a municipal water
				  system.
(2) Only the owner of a
				  municipal water system may submit a request to operate an ASR system.
(3) Completion of an ASR pilot study is
				  required before a municipal water system may submit a request to operate an ASR
				  system.
(4) Completion of an ASR
				  system development test and approval of the department is required before any
				  additional aquifer storage recovery well that was not approved as part of an
				  original request to operate an ASR system is connected to the existing ASR
				  system.
(5) A request to operate an
				  ASR system shall be submitted to the department in writing and shall contain
				  the following:
(a) A copy of the final report
				  of the approved ASR system pilot study and copies of any approved ASR system
				  development studies conducted by the municipal water system.
(b) A final plans and specifications report
				  that describes the components of the ASR system. The final plans and
				  specifications report shall include as built drawings for each aquifer storage
				  recovery well and each monitoring well that was constructed as part of the ASR
				  system pilot study or ASR system development study. The report shall also
				  include descriptions of pumping equipment, piping and other appurtenances that
				  are installed or required for ASR system operation.
(c) A proposed final operating plan that
				  describes the entire ASR cycle and shows how the ASR system will be integrated
				  into municipal water system operations. The proposed final operating plan shall
				  contain details including the total volume of water to be injected, rate of
				  injection, pressure of injection, length of the water storage period, rate of
				  recovery, post-recovery water treatment techniques necessary to maintain a
				  distribution system disinfectant residual, and methods for disposing of any
				  water that cannot be recovered into the water distribution system.
(d) A proposed demand management and water
				  accountability plan that describes actions which the municipal water system is
				  currently conducting or will be initiating to ensure that groundwater and
				  surface water resources are conserved and used as efficiently as
				  possible.
(e) A proposed compliance
				  and monitoring plan that lists all sampling parameters and provides details on
				  monitoring schedules, monitoring locations, sampling methods and quality
				  assurance techniques that will be followed to ensure that compliance with the
				  requirements set forth in s.
				  NR
				  811.88 is maintained. The compliance and monitoring
				  plan shall provide for testing of the water that is to be injected, stored and
				  recovered through each aquifer storage recovery well and for the groundwater
				  present in any monitoring well that is installed as part of the ASR system.
				  Parameters to be analyzed for each water quality sample collected, the
				  locations for sample collection and the frequency at which water quality
				  samples are to be collected shall be determined by the department following a
				  review of the final ASR system pilot study report or ASR system development
				  study report, the proposed operating plan, the proposed monitoring plan and the
				  drinking water quality monitoring schedule currently followed by the municipal
				  water system. Unless otherwise specified by the department, all water quality
				  results obtained from ASR system compliance monitoring activities shall be
				  compiled and submitted to the department on an annual basis and at least 45
				  days prior to the start of each new ASR cycle.
