Holborn and Finsbury Commission of Sewers

Early Commissioners of Sewers were solely concerned with land drainage and the prevention of flooding, not with the removal of sewage in the modern sense. In 1531 an Act of Sewers was passed which set out in great detail the duties and powers of Commissioners and governed their work until the 19th century. Gradually a permanent pattern emerged in the London area of seven commissions, five north and two south of the Thames, with, after the Great Fire, a separate commission for the City of London. The London commissioners had more extensive powers than those in other parts of the country; they had control over all watercourses and ditches within two miles of the City of London as well as newly constructed drains and sewers. After 1800 the London commissioners also obtained powers to control the formation of new sewers and house drains.

On 21 May 1608 a Commission of Sewers was issued to Sir Nicholas Mosley 'maior of London' and others 'for Turnemyll Brooke and Fleets ditche in Lond. & Midd. and the Watercourse that runneth from Clerkenwell to holborne Bridge and soe into the Ryver of Thames' (Stow's Chronicle). Although this appears to be the first of the Holborn and Finsbury Commissions, the next covering this area appears to be that 'for the Cittie of London and two miles from the same' (1615) (Act 6 Hy. VI c.5) though this must have overlapped the area of the Westminster Commission. The later 17th century Commissions have the area of their jurisdiction described in similar terms and it is not until 1699 (Act 23 Hy. VIII c.5) that 'the Divisions of Holborne and Finsbury' are specifically mentioned.

The jurisdiction of the Holborn and Finsbury Commission of Sewers included sewers in Shoreditch, Clerkenwell, Islington, Hoxton, Moorfields, Chancery Lane, Gray's Inn Road, Leather Lane, Saint Pancras, Camden, Gower Street, the Regent's Canal and the River Fleet.
