Each existing system was subjected to soil borings to determine the seasonal <br /> water table depth. When a system was identified as non-compliant, the owner was notified of the need <br /> to bring the system into compliance and given several years to complete the upgrade. <br /> The deadlines to upgrade were divided into whether or not the property was in the Shoreland District <br /> (within 1000' of a lake or within 300' of a protected tributary stream). Properties in the Shoreland <br /> District were given until December 31, 2007 to become compliant. Properties outside the Shoreland <br /> area with non-compliant systems were allowed until December 31, 2010 to conform to the septic code. <br /> The above noted property is located in the Shoreland District and needs to be updated before <br /> December 31, 2007. <br /> Don't wait until the last minute! The City is strongly recommending that property owners not wait <br /> until the deadline arrives to bring their systems into compliance. The process to upgrade your septic <br /> system can be quite lengthy. The first step in the process is to hire a site evaluator and designer to <br /> determine what type of system is required and provide the blueprint for the system installation. <br /> Secondly, the property owner must then contract with a septic system installer to have the system <br /> constructed. <br /> The installation of a septic system is very weather dependent, especially for mound systems, which can <br /> only be installed when the ground is relatively dry, i.e. typically June through September. Contractors' <br /> schedules fill up quickly, so iYs important to start your planning and design process now to ensure a <br /> timely installation. The period of time from deciding to update your septic system to the actual <br /> installation can easity exceed three to four months, or more. Please contact the Building and Zoning <br /> Department at 952-249-4600 with any questions you may have about bringing your septic system into <br /> compliance. <br /> For a list of licensed designers and installers you may go to www.ci.orono.mn.us, click on <br /> City Departments, click on Septic, then click on the link to www.pca.state.mn.us. <br /> Telephone (952) 249-4600 • Fax (952) 249-4616 <br /> www.ci.orono.mn.us <br />
