Upon completion of the installation or renovation of an on -site system the system <br />ow: er or agent shall submit a description of the system as installed to the <br />plumbing inspector. The description shall include site address, location and layout <br />of the system on the site, type and design of system installed, type of building served <br />and the results of the site suitability analysis (percolation tests and/or soil borings). <br />z SubcL 2. bristirg Systems. <br />a. The plumbing inspector or his designated representative shall <br />develop, or cause to be developed, a program whereby existing <br />systems are inspected to determine compliance. The inspection <br />shall be done by the plumbing inspector, his designated <br />representative or the homeowner. If the homeowner does not <br />choose to make his own inspection, then he m._y, by written <br />request and payment of an inspection fee as determined by City <br />Council resolution, request the plumbing inspector to make the <br />initial inspection. The inspection shall be conducted so as to <br />cause minimum damage to the property. It shall be the duty of <br />the owner or occupant of the property to give the plumbing <br />inspector or his designated representative free access to the <br />property at reasonable times for the purpose of malting all system <br />inspecti ons. <br />b. The plumbing inspector, or his designated representative or the <br />homeowner shall inspect every individual waste disposal system <br />within the City of Ramsey every 24 months to ensure continued <br />compliance with this chapter. During this routine inspection, the <br />plumbing inspector shall specifically determine the need for <br />sludge and/or scum removal from septic tanks based on <br />measurements of existing conditions. Maximum allowable <br />levels, determined as outlined in §8.30.05 Subd. 2c. Septage <br />should be removed from the tank whenever the top of the sludge <br />layer is less than 1.2 inches below the bottom of the outlet baffle or <br />whenever the bottom of the scum layer is less than 3 inches above <br />the bottom of the outlet baffle. <br />c. Scum can be measured with a stick to which a weighted flap has <br />been hinged or with any device which can be used to detect the <br />bottom of the scum mat. The stick is forced through the mat, the <br />hinged flap falls into a horizontal position, and the stick is raised <br />until resistance from the bottom of the scum is felt. The same <br />device can be used to determine the distance to the septic tank <br />outlet device. A long stick wrapped with rough absorbent <br />material and lowered to the bottom will show the depth of sludge <br />and the liquid depth. The stick must be lowered in such a tank; <br />location as to avoid unrepresentative readings that might be <br />caused by interference from the scum layer. <br />Subd. 3. Approved Systems.
