Prior to the installation of an aerated treatment system, plans and specifications shall be submitted to the Planning and Development Department for approval. Specifications for aerated treatment systems shall include, but not be limited to, the following:
(A) Chlorinator. Aerobic systems must contain sufficient chlorine at all times for proper disinfection;
(B) The aeration unit should have a trash collecting section;
(C) The aeration unit must be guaranteed to treat at least 500 gallons of domestic sewage per day;
(D) A clearly labeled warning light or buzzer must be provided that warns the owner of the failure of any electrical or mechanical component of the system;
(E) A service contract should be available to which the home owner may subscribe if he or she so desires. A replacement policy governing all mechanical and electrical component parts should be furnished by the manufacturer to each owner;
(F) All mechanical and electrical component parts should be granted against defects in materials and workmanship;
(G) The aeration unit shall not have an effluent discharge directly to the surface of the ground except as discussed in division (H) of this section. Each aeration unit shall be followed by one of the following secondary treatment systems:
(1) Subsurface seepage field;
(2) Sand filtration with effluent chlorination; or
(3) Waste stabilization pond with effluent chlorination.
(H) Approval for aerated treatment systems with a surface discharge may be granted provided that:
(1) The Planning and Development Department is provided sufficient evidence that the system is capable of producing an effluent on a continuous basis that meets the water quality criteria. See effluent standards; and
(2) If the operation of a system results in an unsatisfactory effluent, then additional treatment shall be installed as required by the Building and Zoning Department.
(I) Type of pipe. Aerobic systems shall be constructed with Schedule 40 type pipe throughout system including discharge pipe;
(J) Discharge pipe shall be capped with a perforated cover;
(K) Discharge pipe shall be maintained properly and be readily accessible to allow for sanitary sampling purposes of effluent discharge;
(L) Effluent draining from discharge pipe shall immediately empty into a “rock filter bed” constructed as follows (see Attachment C, which is attached hereto and made a part by reference hereof):
(1) Rock size: three-fourths inch (pea gravel is prohibited); and
(2) Trench size:
(a) Minimum length, six feet;
(b) Minimum width, 18 inches; and
(c) Minimum depth, 12 inches.
(M) End of discharge pipe must be located a minimum of 25 feet (more if possible) inside property boundary line with proper “rock filter bed” as described above. All discharge points from aeration or sand filtration systems must be a minimum of 235 feet from any other aeration or sand filtration discharge point;
(N) Minimum distances allowable from aerobic system discharges are as follows:
Well | Water Supply (Pressure) | Lake, Stream, Body of Water (feet) | Dwelling | Property Line | Field Drain Tile | |
Aerobic | 50 | 10 | 50 | 5 | 25 | 10 |
Sand filter | 100 | 25 | 75 | 10 | 25 | 10 |
(O) Common collector line must be located on recorded easements and constructed according to specifications located in Attachment B, which is attached hereto and made a part by reference hereof.
