[10 Emptying of septic tanks.S
(1)It shall be the duty of [Scottish Water] to empty a septic tank serving premises in [its] area on [its] being requested to do so by the owner or occupier of the premises; but that duty is subject to subsection (2) below and as respects any particular septic tank—
(a)to its being reasonably practicable to empty the tank; and
(b)to all proper charges for [its] doing so being timeously paid.
(2)The duty does not extend to septic tanks which receive trade effluent; but [Scottish Water] may, at the request of an owner or occupier of premises served by any such septic tank, agree to empty it on such conditions as to payment or otherwise as [it thinks] fit.
(3)If any question arises under this section as to whether emptying is reasonably practicable or as to whether a septic tank receives trade effluent, it shall be determined summarily by the sheriff, whose decision in the matter shall be final.
(4)For the purposes of subsection (1) above, a charge is proper if fixed in accordance with, and timeously paid if paid in accordance with, a charges scheme (within the meaning of [the Water Industry (Scotland) Act 2002 (asp 3)]).]
