SECTION 4 – SANITARY <br />49 <br />New manholes, catch basins, and inlets recently installed, shall be lined with a non-structural <br />corrosion barrier. The lining shall be installed to the thickness necessary to qualify as a <br />monolithic (void free) line. The roughness of the substrate will dictate the thickness needed to <br />create the monolithic liner and eliminate any opportunity for voids in the lining. The minimum <br />value for coating thickness for corrosion protection for non-structural lining shall be 125 mils. <br />4-2.8 LIFT STATION <br />Section under development. <br />4-2.9 MISCELLANEOUS <br />4-2.9 (a) CONCRETE SADDLE <br />The concrete saddle shall be as shown on Standard Drawing 4-12. <br />4-2.9 (b) STEEL CASING PIPE <br />Steel casing pipe shall conform to ASTM A139, Grade B. The minimum wall thickness shall be <br />0.375 inches for casing pipe diameter up to and including twenty-six (26) inches, minimum wall <br />thickness shall be 0.50 inches for casing pipe diameters between twenty-seven (27) inches and <br />forty-two (42) inches, and minimum wall thickness shall be 0.5625 inches for casing pipe diameters <br />between forty-three (43) and forty-eight (48) inches. Casing spacers shall be stainless steel. The <br />steel casing pipe and casing spacers shall comply with Standard Drawing 4-10. <br />4-2.9 (c) SEWER TAP <br />The sewer tap shall be as shown on Standard Drawing 4-7. <br />4-2.9 (d) FLOWABLE FILL (REMOVABLE) <br />Removable flowable fill mix design shall comply with INDOT Standard Specifications Section 213. <br />4-2.9 (e) MISCELLANEOUS CONCRETE <br />Where called for, concrete shall be Class A conforming to INDOT Standard Specifications Section <br />702. <br />4-2.9 (f) PIPE INSULATION <br />Section under development. <br />4-2.9 (g) PIPE DETECTION TAPE <br />Detection tape shall be placed over PVC or HDPE force main pipe as shown in Standard 4-13. <br />Detection tape shall be three (3) inches wide with an overall thickness of five (5) mil. The tape <br />shall have a 0.35 mil solid aluminum foil core. The tape shall have 0.80 mil clear film, reverse
