As part of the great post-WW2 planning reforms, and a move towards wider planning reform to better manage the UK's housing, industrial, infrastucture and land use, most areas of the country produced a planning report. Many of these, now famous documents, were for individual local authorities but the larger conurbations were already recognised as having distinctive regional concerns and here in South Lancashire and North Cheshire the Planning Advisory Committee issued a large report on what was broadly described as the 'river basins of the Mersey & Irwell".
This committee actually had quite a pedigree as it sprang from the formation in 1923 of a Manchester & District Joint Planning Advisory Committee - an ealry example of an attempt to coordinate issues on a sub-regional basis. The early attempts did not really come to much - there was, in the late 1920s for example, an attempt to look at a joint passenger transport scheme that again failed apart from a short-lived regional express bus service killed off by the Traffic Commissioners in 1930/32. Indeed, really, it took until the local government reorganisations of 1974 and the creation of Metropolitan County Councils to bring many of the amalgamated functions together and even they were short-lived.
The Report, issued in 1947, was part of a trio of reports - the City of Manchester's own plan of 1945 and the Manchester & District Regional Plan of the same year. This report includes a series of maps and plans showing major infrastructure across the whole region such as communications, water and sewage and energy supplies. The latter - gas and electriicty undertakings - are shown at the very end of the pre-nationalisation period as in 1948/9, under the post-war Labour administration, both gas and electricity were nationalised. The map shows the supply areas of the various undertakings - many larger boroughs had municipally owned undertakings but smaller boroughs and rural areas were served by various privately owned companies - the most dominant here being the Lancashire Electric Power Company. The other major player was the vast Manchester Corporation Electricity Department. Two other interesting 'players' both with transport links. The wonderfully named SHMD Board was a joint board of four small Cheshire municipalities that banded together to promote a tramway network and the electricity supply to power them and that survived the nationalisation of the electricity side of the business to run trolleybuses and buses until 1969 when it was merged into SELNEC. The other - the South Lancashire Transport Company, allied to the Lancashire United Transport Company, SLT had powers to run trolleybuses and generate the power for them.
The move towards coordination in the electricity industry was stronger than in the gas industry and from the 1920s onwards government policy forced a move towards larger and more efficient generating stations, connected by a national grid and simplified generating and supply voltages and phases. This meant that many of the smaller undertakings here would no longer have generating plants but would take bulk supplies from larger and more efficient 'selected stations'.
Water and sewage were slower to be rationalised over stages with larger 'joint boards' being formed to manage sewage and wastewater and some rationalisation of water undertakings prior to the creation in 1974 of regional water boards that took responsibility for river catchment boards, sewage works and water supplies.
The comminication map highlights the early planning around 'national routes', destined to become the later Motorway network.
The Plan was prepared by R Nicholas (Hon Surveyor to the Committee) and M J Hellier (Planning Officer to the Committee).
