'� � , <br /> s, �: . .� <br /> �. . <br /> , To: Orono residents on mound type septic systerns <br /> �� From: Wiliie Gibbs, ISTS Manager <br /> i Date: May 10,2006 <br /> � Re: Landscaping Do's and Don'ts for Mound Systems, Quick Reminder <br /> II 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"ather" stuff has been removed) <br /> in the summer time and allows the mQund 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 resutting 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 potential failure. <br /> Do not plant trees or shrubs on the mound system, smaller trees and shrubs may be planted at the <br /> edges. Remember,that sunshine is fihe key to a healthy mound system. <br /> � Do ask questions, if you have any concems or questions concerning your mound system <br /> please feel free to call me,I can be reached at 952-249-4626. <br /> I <br /> �I <br />
