WELL CONSTRUCTION AND PUMP INSTALLATION BY THE WELL OWNER You may construct the well and/or install the pump yourself if the well is for your own use, is on property you own, and is constructed or pumping equipment is installed with equipment owned and operated by you. It is your responsibility to complete and submit the Well Construction and Test Report, Form Number GWS-31 and/or the -Installation and est Report, Form Number GWS-32. I hese forms are available from our affices. I he well must be constructed and the pump installed in accordance with the well construction standards of the State Board of Examiners of Water Well Construction and Pump Installation Contractors. The Water Well Construction Rules are available from Division of Water Resources offices for a fee of$5.00. The Rules cover the minimum requirements for well construction, pump installation, disinfection, plugging and sealing and include contractor licensing regulations. If you are constructing your own well or installing pumping equipment, it is recommended that you obtain a copy of these Rules for reference. RULE 12 WELL TESTING 12.1 General -The provisions of this rule establish minimum standards for the testing of water wells. Every well constructed for the purpose of producing ground water shall be tested to determine: a. a stabilized yield for the well; and b. the production rate of the equipment installed when the well is placed into service. 12.2 'IMI Yield Test -'The yield;of a well shall be determined as a,.stabilized production rate where the withdrawal rate and the drawdown do not change by more than 10 % during the last hour of the test. The test shall demonstrate that either: a. the well is capable of producing the permitted pumping rate for the well; or b. that the maximum yield of the well is less than the permitted production rate. 12.3 Responsibility for Well Yield Test - Well construction contractors are responsible for performing the well yield test and submitting the test data to the State Engineer. If the construction contractor also installs the production equipment, the well yield test may be combined with the production equipment test, provided that the test meets the requirements of Rule 12.2. The construction contractor may forgo the well yield test if he can show that a 'licensed pump installer will perform the well yield test with the permanent production equipment within thirty (30) days of completion of construction of the well. If the pump installation contractor performs the well yield test, he/she shall submit the test information on the Pump Installation'and Test Report. 12.4 Production Equipment Test -The production equipment installed in wells shall be tested to ensure it is functioning as designed. The test shall demonstrate the production capacity of the equipment as actually installed in the well. It is the responsibility of the person installing the pumping system to ensure that the production from the well complies with the conditions of the permit. 12.5 Responsibility for Production Equipment Test - Pump installation contractors are responsible for testing the production equipment installed in a well upon completion of their work. If the well construction contractor determined the well yield and submitted a report, the pump installer need not perform another well yield test. If the pump installer does not perform a well yield test with the permanent production equipment, he shall perform a production equipment test and report the data (results) to the State Engineer on the Pump Installation and Test Report.. Wells to be plugged and sealed must be plugged in accordance with of the Water Well Construction Rules. A Well Abandonment Report,form number GWS-9 must be submitted to confirm plugging and sealing of the well. This form is available from our offices. The general Rule for plugging and sealing wells is printed below. The specific rules are found on the reverse side of the Well Abandonment Report form. RULE 16 STANDARDS FOR PLUGGING AND SEALING WELLS AND WELL EXCAVATIONS 16.1 General - The plugging, sealing and abandonment of all wells, monitoring and observation wells, monitoring and observation holes and test holes that are no longer intended for use, and the plugging, sealing, and abandonment of dry holes, collapsed or unusable boreholes, and other incomplete wells or excavations is necessary to prevent contamination of ground water and the migration of water through the borehole. It is the ultimate responsibility of the well owner to have an existing well properly plugged;'sealed and abandoned. The well construction contractor or authorized individual is responsible-for notifying the well owner in writing of these plugging requirements.
