“ The function of the Board is to provide all necessary facilities for the reception of sewage from the several districts incorporated within the Drainage District, and to make provision for the proper discharge of such sewage into the harbour at Okahu Point. Reticulation sewers are provided by the several local authorities, by-laws of the Board regulating their design and construction.
The scheme has been designed for an area of 18,900 acres with an estimated ultimate population of 280,000 persons on a basis of 210 gallons per capita per diem, or six times a dry-weather flow of 35 gallons. ”

“ Two loans, amounting to £5,500, raised by the late Hobson Bay Watershed Sewage Board, are also liabilities of the Board, the public debt of which ts therefore £455,500.
Repayment of loans is provided for by a sinking fund administered by the Auckland and Suburban Drainage Loan Commissioners. The accumulated amount in the fund at March 31st, 1921, was £25,436 15s.
The ordinary income and revenue of the Board is derived by assessments levied annually upon the contributing authorities. ”

“ Bush was eventually instructed to prepare a scheme for the main drainage of Auckland and suburbs, the Auckland Harbour Board being at the same time requested to allow of the discharge of sewage at Okahu Point. ”
