31Charges schemes
(1)Scottish Water must, in accordance with this section, make a scheme (referred to in this Act as a “charges scheme”) which fixes the charges to be paid for services provided by it in the exercise of its core functions and which may also make provision with respect to the times and methods of payment of the charges fixed by the scheme.
(2)Subsection (1) does not apply in relation to services as respects which conditions as to payment may be imposed under section 29(3)(j) of the 1968 Act (conditions relating to the reception, treatment and disposal of trade effluent).
(3)A charges scheme may—
(a)make different provision for different cases, or classes of case, including different provision in relation to different circumstances or localities,
(b)contain supplemental, consequential and transitional provisions for the purposes of the scheme,
(c)revoke or amend a previous scheme.
(4)A charges scheme comes into force only when it is approved in accordance with section 32 and has effect as so approved.
(5)Scottish Water in making a charges scheme, and the Commissioner and the Scottish Ministers in considering whether to approve such a scheme, must have regard to any advice published under section 33 in force at the time of the making of the scheme.
(6)Nothing in any charges scheme affects any power of Scottish Water to enter into an agreement with any person in any particular case determining the charges to be made for services provided by Scottish Water.
