Diagram of the Richmond water supply
Richmond water supply covers properties from Wakatu Industrial Estate in the north to Haycock Road rural extension in the south. It includes the Richmond and Waimea Industrial zones.
The ‘Richmond zone’ covers the urban area as far as Templemore Drive and Arbor Lea Ave. The supply extends south to Bateup Road, and includes a rural extension along Hill Street South. Connections are metered in the urban area, with restrictors in the rural area.
The ‘Waimea Industrial Zone’ covers the area around Champion Road, south to Templemore drive and Heritage Crescent and Arbor Lea and includes the Daelyn Drive area (in Nelson). It also includes Wakatu Industrial Estate, McPherson St, Fittal St and Cargill Place. This zone is fully metered.
Water is sourced from two sets of bores which are mixed in-line, disinfected with UV and pH corrected using caustic soda. Permanent chlorination was introduced in May 2021.
