r � <br /> • / • • <br /> e <br /> To: Orono residents on mound type septic systems <br /> From: Wiliie Gibbs, ISTS Manager <br /> Date: May 10, 2006 <br /> Re: Landscaping Do's and Don'ts for Mound Systems, Quick Reminder <br /> Do plant and maintain a full cover of grass and keep mowed to a normal height, this grass cover aids <br /> in the evaporation of large amounts of effluent (the liquid left after the "othe�' stuff has been removed) <br /> in the summer time and ailows the mound system to help breakdown nitrogen in the effluent, <br /> Do water the grass over the mound in extreme dry conditions, sparingly. <br /> Do avoid unnecessary foot traffic over the mound, mow it and stay off of it. This is especially true in the <br /> winter time. Even human foot traffic can cause frost to penetrate the mound resulting in potential <br /> freezing problems. <br /> Do inspect your mound system annually for winter kill, (reseed if necessary) animal damage, <br /> (burrowing)or signs of potentiai failure. <br /> Do not plant trees or shrubs on the mound system, smalier trees and shrubs may be planted at the <br /> edges. Remember, that sunshine is the key to a healthy mound system. <br /> Do ask questions, if you have any concerns ar questions concerning your mound systerr9 <br /> please feel free to call me, ! can be reached at 952-249-4626. <br /> 1 <br />
