Certified Well Contractors – The installation of all water wells in Iowa requires the homeowner to hire an individual Well Driller certified Iowa DNR to perform the well construction or do the real work itself. All well structures must meet minimum construction standards for the installation area. Iowa DNR does not recommend that you provide good services yourself. This is because good services are specialized work that requires specialized knowledge, skills and tools. In addition, this type of work can be dangerous for your personal safety and groundwater. Also, if you complete some of your work and then need a certified well contractor to complete the job, it can cost you more than if the contractor solved your well problem from the beginning. If you hire a well contractor, make sure they are currently certified with the DNR Well Contractor Iowa certification in the correct well service disciplines. Construction Standards National well construction standards provide a minimum of well protection, but some areas of the state may require greater protection that can be used in the construction of the well. Increasing the quantity and depth of the envelope to avoid poor groundwater quality and/or pushing the well to a deeper level will help ensure long-term protection of the water supply and well, and the aquifer is specific to the area where the well is located. The job is easier if you understand your role in developing a safe water supply. It also involves understanding how local land use patterns can interact with local geology and influence your well. It also means installing your well in a protected area away from sources of pollution. Must have a legally binding common well agreement for signatories and rights holders – a minimum flow rate of three gallons per minute.
A lower yield is permitted if a pressurized deposit of no less than 720 gallons is made available to each dwelling. Performance must be proven by a certified pumping test. The simplest way for the parties to indicate their purpose for the well is to explicitly limit the well to domestic use. Idaho exempts domestic groundwater uses from most permit and royalty requirements.  Idaho defines domestic uses as “water for homes, organizing camps, public campsites, livestock and other purposes, including irrigation of half a hectare (1/2) of hectares if the total use does not exceed thirteen thousand (13,000) gallons per day.”  However, if the owner uses water for several property areas, trailer parks, commercial or commercial buildings, it is limited to 2500 gallons per day.  For many landowners, limiting their agreement to national uses will cover their water needs. If the use of the parties exceeds the legal definition of domestic use, they must acquire a new right to water. Competent written agreements can also be controversial. Some of these controversies arise because reasonable minds are not related to the best way to approach a problem, as if the well pump breaks and there is more than one way to repair it or repair options vary in their cost and efficiency.
