The River Cart and the White Cart are
navigable to Paisley; being blocked in the 1960s, at Sneddon Street, by the aqueduct under the Piazza Shopping Centre.
18th and 19th century improvements The
Paisley Beer Duties Act 1753 provided for "laying a duty of
two pennies Scots, or one sixth part of a penny Sterling, on every Scots Pint of Ale and Beer which shall be brewed for sale, brought into, tapped or sold within the Town of Paisley and Liberties thereof, in the County of Renfrew, for improving the Navigation of the River Cart, and for other Purposes". A further
act of Parliament, the '''''' (
27 Geo. 3. c. 56), was obtained by the Cart Trust for the river's improvement in 1787, in response to pressure from Paisley's shipbuilders. This led to some improvements around Inchinnan. The first
steamer service to Paisley, provided by the
Prince of Orange, started in July 1815. The original Swing Bridge, at Inchinnan, on the
Turn Pike road, now the
A8, was opened in 1838; the mechanism for swing bridge was made by Barr and McNab of the Abercorn Foundry, Paisley. The railway was intended to both enhance the capabilities of the River Cart navigation as well as competing against it for goods and passenger traffic. The Cart Trust later went
bankrupt. The
Forth and Cart Canal, opened in 1840, together with the
Forth and Clyde Canal, was intended to provide a direct link between Paisley,
Port Dundas,
Edinburgh, and the
Firth of Forth, without the need to go down the River Clyde to
Bowling and return along the Forth and Clyde Canal to almost the starting point. The original swing bridge at Renfrew was replaced in 1923 by a
bascule bridge, which was made by
Sir William Arrol & Company. An Act of Parliament was obtained in 1938 by the
Ministry of Transport, the
Admiralty and the Ministry of Shipping. A
harbour was built at Laigh Park (Laighpark harbour) at which large cargo
boats /
ships could load and unload; it was linked to the Paisley and Renfrew Railway. This was used extensively during
World War II. Carlile Quay being used for smaller boats. The navigation lights were also upgraded. The harbour fell into disuse in the 1960s and has been used as a
scrapyard for many decades. Carlile Quay has been landscaped, refurbished and made more attractive to pedestrians. Apartment buildings and houses have been built on the vacant site adjacent to the quay.
21st century developments As referenced above, the Carlile footbridge was reopened in November 2021. Around the same time, a new road bridge was being constructed further downstream between Wright Street in Renfrew and Arran Avenue at the
Glasgow Airport long stay car park. Known as Barnwell Street bridge, it was officially opened in August 2022. Due to its low clearance, this static bridge limits upstream navigation to smaller craft only.
Sewage All of Paisley's
sewage and industrial
effluent had been discharged untreated into the River Cart via its tributaries: the St Mirin Burn, the Lady Burn, the Sneddon Burn, the Espedair Burn, etc. By 1870 this had led to many complaints about smells and
epidemics. "Intercepting sewers" were therefore built on either side of the St Mirin burn to intercept the sewage and discharge it directly into the White Cart Water. Whilst this helped clean up Paisley it did not clean up the River Cart. It led to complaints from
Johnstone,
Renfrew and
Glasgow and calls by them for Paisley to provide a sewage treatment farm. Johnstone,
Bridge of Weir,
Lochwinnoch and Glasgow already had sewage treatment farms. Glasgow's works had begun operations in 1894. Land at Laigh Park was bought for this purpose between the first and second World Wars although construction work did not start until 1949 with the works opening in 1952. The sewage works were linked to the intercepting sewers and took all of Paisley's sewage and industrial effluent for treatment.
Water power Both the Black Cart Water and the White Cart Water provided power to drive
mills. The best preserved on the White Cart is Dripps Mill in Waterfoot, which still has two functioning 19th century waterwheels . ==See also==
