Home My WebLink AboutT10N R2E SEC 19 Lot 72 Girdwood School Site MEMORANDUM DATE: November 19, i981 TO: FROM: Kay Topolski Property Management Division Health and Environmental Protection SUBJECT: Girdwood School Site The Girdwood School has a well and an on-site sewer system. The on-site sewer system has very little information known about it due to the age of the system predating inspection requirements. This department could evaluate the facility if specific engineering data is obtained thru testing. Specific data required is as follows: (1) An adequacy test on the absorption field to determine the actual ability of the sewer system disposal area. (2) Determination of the septic tank size and proof of proper baffel design. (3) Exact distances between the well and septic tank, absorption area. Attached is a post-earthquake study of the site. Information is limited, but of value in making the tests. This department will review and conm]ent on the data at your request. A listing of local firms currently conducting adequacy tests is enclosed. Les N. Buchholz, R.S.

A~.ghur Benedict & O~n Renshaw Dickinson Oswald & Associates DEFINITION OF TERMS SEPTIC TANK: A watertight element designed to receive raw sewage;' To provide removal of settleable and floatable solids; ~o provide biological decomposition of the solid and liquid fraction of the raw sewage; and to provide storage of sludge CESSPOOL: An element which is designed to serve th~ same purpose as a septic tank except that it is not watertight a'nd thus permits leaching of treated waste (largely liquid) into the surrounding soil. LEACHING FIELD: An element designed to receive only treated sewage (largely liquid) or liquid waste; its purpose is to distribute liquid throughout surrounding soil. Constructed as a network of peDforated pipes, open-jointed drain tile, or similar material. SEEPAGE PIT: An element which ser~es the same purpose as a leach- ing fzeld. Constructed as a pit with open-jointed lining.
