Water
- The Patearoa water supply feeds both the Patearoa urban supply and the Patearoa rural water scheme The township also has a number of holiday homes and the population peaks during summer months.
- Approximately 50 properties are fed off the town supply and 283 rural units of 1m3/day each are allocated to about 40 properties (farming and residential)
- The Patearoa reticulation is approximately 20km in length
- Annual average water consumption is approximately 250,000m
Patearoa water is sourced from a gallery in the bed of the Sowburn River, a tributary of the Taieri River. Water is pumped from a pump chamber in the Sowburn to the main rural reservoir on the hill behind Patearoa. Water is chlorinated as it passes the treatment plant and eventually enters the main reservoir where disinfection and storage takes place. Water is drawn off into a bank of six farm tanks that serve the urban area of Patearoa. Water is gravity fed to all parts of the rural scheme.
Ranfurly Water Supply
- Resident population of around 800 people
- Approximately 16km of reticulation
- Annual average consumption of water of approximately 260,000m
Ranfurly water is primarily sourced from the East Eweburn. There are two intake structures - a low concrete dam where the creek leaves the hills, and gallery pipes in the creek bed gravels about 1km upstream from Smiths Road. The Hawkdun-Idaburn Irrigation Race provides a secondary source of water used during periods of dry weather when the Eweburn is too low.
The Ranfurly water supply is gravity fed from source to customer. Water flows to the reservoir via a slow sand filter. The water is disinfected by liquid chlorine prior to reservoir storage and is gravity fed to the town reticulation.
Roxburgh/Lake Roxburgh Village Water Supply
- Permanent population of around 620 in Roxburgh and 50 in Lake Roxburgh Village. The population can increase by around 500 people during peak holiday periods
- The length of the Roxburgh/Lake Roxburgh reticulation is 21.7 km
- Annual average water consumption of approximately 300,000m
Roxburgh water is drawn through two bores on the Clutha right bank, approximately 600m north of the Roxburgh township boundary. Water is chlorinated as it enters the main reservoir where disinfection and storage takes place prior to flowing to the town consumers by gravity.
The Roxburgh supply feeds both Roxburgh Township and Lake Roxburgh Village, which are connected by a water pipeline alongside State Highway 8. The pipeline also feeds approximately 20 rural properties on a restricted supply basis.
