including
- Ayr/Brandon Water Supply Scheme
- Home Hill Water Supply Scheme
- Giru Water Supply Scheme; and
- Mt Kelly Water Supply Scheme
Water schemes for the villages of Clare, Millaroo and Dalbeg are operated
by Sunwater.
Ayr/Brandon Water Supply Scheme
Three borefields supply the Ayr/Brandon scheme:

The Nelsons Lagoon borefield supplies water to a 0.45 megalitre water tower
in Canberra Street, Ayr. This tower then supplies the Ayr/Brandon water reticulation
system. The water is chlorinated by injection into the delivery main to the
tower.

Home Hill Water Supply Scheme
The Home Hill Borefield consists of 8 bores located on the western side of
town. This supply is supplemented by 2 emergency bores with separate chlorinators
located within the distribution area.
The capacity of the borefield with 8 pumps operating is 290l/second.
Water from the Home Hill Borefield is chlorinated and aerated before discharge
into the Home Hill Water Tower.

Giru Water Supply Scheme
Water for the Giru water supply scheme is supplied by Citiwater (a commercialised
business unit of Townsville City Council) from their Cungulla Treatment Plant.
Council maintains a treated water pump station within the Cungulla Treatment
Plant Site which provides water to ground level storages at the Giru depot
site. Treated water is rechlorinated at the depot and pumped to an elevated
storage before distribution to the Giru Reticulation. Council also maintains
emergency bores, stand-by chlorination facilities and interconnection pipework.

Mt Kelly Water Supply Scheme
The Mt Kelly Water Supply Scheme serves the rural residential area of Mt.
Kelly. Raw water is drawn from the Mt Kelly Borefield, chlorinated and pumped
to a 60kl breaker tank before being re-pumped to the gravity aerators and
640kl storage reservoir on Mt Kelly.
The Mt Kelly Borefield consists of three bores with bore 1 having the capacity
of 40l/second and bores 2 and 3 which usually operate together to give a combined
capacity of 40l/second.

Treatment Plants
Both of Council's treatment plants are conventional trickling filter plants.
The Ayr/Brandon treatment plant has a design capacity of 14,000 EP with a
design ADWF (Average dry weather flow) of 36.5 litres per second. The licensed
discharge is for 3.5ML/day with BOD5 not to exceed 20 mg/L and non-filterable
residue not to exceed 30 mg/L.
The Home Hill treatment plant has a design capacity of 4,800 EP and a licensed
effluent standard similar to Ayr/Brandon with a licensed discharge of 1.2ML/day.
