A � <br /> • � • • <br /> � . <br /> To: Orono residents on mound type septic systems <br /> From: Wiilie 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 normai 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 potentiai <br /> freezing problems. <br /> Do inspect your mound system annually for winter kiil, (reseed if necessary) animal damage, <br /> (burrowingj or signs Qf 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 the key to a healthy mound system. <br /> Do ask questions, if you have any concerns or questions concerning your mound system <br /> please feel free to call me, l can be reached at 952-249-4625. <br /> 1 <br />
