Manhole covers also prevent objects and debris from getting into the drainage system where it could cause a blockage.

This can help to prevent damage to the system and minimise disruption to the people using the building and the surrounding area. chambers) /Next 112 0 R /Prev 116 0 R /Parent 79 0 R /A 117 0 R >> endobj 115 0 obj << /S /GoTo /D [ 7 0 R /Fit ] >> endobj 116 0 obj << /Title (7.03 Manholes) /Next 114 0 R /Prev 118 0 R /Parent 79 0 R /A 119 0 R >> endobj 117 0 obj << /S /GoTo /D [ 4 0 R /Fit ] >> endobj 118 0 obj << /Title (Deep inspection chambers cont) /Next 116 0 R /Prev 120 0 R /Parent 79 0 R /A 121 0 R >> endobj 119 0 obj << /S /GoTo /D [ 4 0 R /Fit ] >> endobj 120 0 obj << /Title (Deep inspection chambers) /Next 118 0 R /Prev 122 0 R /Parent 79 0 R /A 123 0 R >> endobj 121 0 obj << /S /GoTo /D [ 4 0 R /Fit ] >> endobj 122 0 obj << /Title (7.02 Preformed plastic inspection chambers) /Next 120 0 R /Prev 124 0 R /Parent 79 0 R /A 125 0 R >> endobj 123 0 obj << /S /GoTo /D [ 1 0 R /Fit ] >> endobj 124 0 obj << /Title (7.01 Access to drains) /Next 122 0 R /Prev 80 0 R /Parent 79 0 R /A 126 0 R >> endobj 125 0 obj << /S /GoTo /D [ 1 0 R /Fit ] >> endobj 126 0 obj << /S /GoTo /D [ 1 0 R /Fit ] >> endobj 127 0 obj << /S /GoTo /D [ 78 0 R /Fit ] >> endobj 128 0 obj << /ProcSet [ /PDF /Text /ImageC /ImageI ] /Font << /F1 130 0 R /F18 135 0 R >> /XObject << /Im89 140 0 R >> /ExtGState << /GS1 137 0 R >> /ColorSpace << /Cs5 132 0 R /Cs9 129 0 R /Cs18 133 0 R >> >> endobj 129 0 obj [ /Separation /PANTONE#20321#20 132 0 R 138 0 R ] endobj 130 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 251 /Widths [ 343 384 500 686 686 975 848 250 352 352 483 686 343 392 343 579 686 686 686 686 686 689 686 686 686 686 343 343 686 686 686 595 740 781 677 660 752 550 542 842 803 324 489 758 495 983 881 887 661 887 680 616 533 778 761 1117 789 714 707 350 579 350 686 500 402 682 682 483 682 610 388 677 661 302 302 688 302 989 661 662 682 682 453 513 360 659 623 996 712 654 559 352 579 352 686 343 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 686 686 0 0 0 0 0 800 0 0 0 343 0 0 343 686 343 343 0 659 343 343 343 343 343 0 0 343 0 0 0 0 0 343 0 343 343 0 0 0 343 0 0 0 0 0 0 0 0 0 372 372 0 343 0 0 194 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 343 0 0 0 0 0 0 0 0 0 0 457 ] /Encoding /MacRomanEncoding /BaseFont /Futura-Bold /FontDescriptor 131 0 R >> endobj 131 0 obj << /Type /FontDescriptor /Ascent 830 /CapHeight 754 /Descent -256 /Flags 262176 /FontBBox [ -171 -264 1441 1040 ] /FontName /Futura-Bold /ItalicAngle 0 /StemV 182 /XHeight 513 >> endobj 132 0 obj [ /CalRGB << /WhitePoint [ 0.9505 1 1.089 ] /Gamma [ 2.22221 2.22221 2.22221 ] /Matrix [ 0.4124 0.2126 0.0193 0.3576 0.71519 0.1192 0.1805 0.0722 0.9505 ] >> ] endobj 133 0 obj [ /Indexed 132 0 R 255 139 0 R ] endobj 134 0 obj << /Length 984 /Filter /FlateDecode >> stream Your property right up to a particular point in the drain junctions and saddles of drinking water that used.
