Source Water. MCWRA will design and construct, in consultation with Cal-Am and MCWD, new xxxxx for the extraction of brackish source water, to be owned and operated by MCWRA and located on MCWRA-owned real property. MCWRA will also own and operate existing monitoring xxxxx as Inland Water Monitoring Xxxxx, and if necessary, may design and construct up to seven new inland monitoring xxxxx to monitor the impact of the extraction of the brackish source water on the Xxxxxxx Valley Groundwater Basin. MCWRA will also design and construct (in consultation with Cal-Am and MCWD) and will own and operate a series of water conveyance facilities to convey the brackish source water from the xxxxx (each of which will have a brackish source water meter) to the brackish source water receipt point meter. These facilities are known as the MCWRA Brackish Source Water Pipeline.
Source Water. WRA shall obtain water rights to Drainage Flows from the California State Water Resources Control Board. Costs of obtaining and maintaining said water rights shall be reimbursed to WRA on a proportional basis for water used as a component of the New Source Facilities.
Source Water. Raw water for the Walgett drinking water supply system is sourced from the Namoi River. The Namoi River is one of the Xxxxxx-Xxxxxxx Basin’s major NSW sub-catchments. It covers a total area of about 42,000 square kilometres from the Great Dividing Range near Tamworth to the junction with Barwon River near Walgett. Water quality in the Namoi River is often poor due to intensive farming in the catchment and blue-green algae.
Source Water. The Collarenebri drinking water supply system is sourced from the Barwon River from Walgett. The Barwon-Darling is considered an unregulated river above the Menindee Lakes. There are many weirs in the Barwon-Darling that have a major influence on water quality and water supply for users along the river. The water quality in the Barwon River is notably of high turbidity and high colour due to extensive clearing and agricultural landuse in the catchment. There are approximately 18,500 people residing in the Barwon-Darling catchment with the catchment representative of a large Australian dryland river system with mainly agricultural production of dryland grazing and cotton plantations. In addition to the drinking water supply system, Walgett Shire Council supplies raw water from the Barwon River to Collarenebri and the Walli Aboriginal Reserve.
Source Water. The system sources raw water from the GAB Shallow Groundwater Source via the Bungara Bore which has a depth of 102m. The Xxxxxx Bore is located out of town in the middle of a wheat farming and grazing property. The bore may become inaccessible during flood events and as the bore is not fully sealed, contamination from the surrounding property may be possible. Water Treatment The Xxxxxx water supply is not treated or disinfected. Distribution Water is stored in two tanks and reticulated through Xxxxxx town via gravity. Schematic
Source Water. The system sources raw water from the GAB Shallow Groundwater Source via the Cumborah Bore. The Cumborah Bore (Licence 85BL241927) was constructed in 2004 to a depth of 773m. The water is stored in two tanks at Cumborah. Water Treatment The Cumborah water supply is not treated or disinfected.
Source Water. This is an artesian bore that accesses the GAB. The water is stored in two tanks at Carinda. Water Treatment This supply is not treated or disinfected.
Source Water. A greater proportion of intervention households than control used a piped water source on the household premises (67% v. 7%), with fewer intervention than control households using a public piped water source (4% v. 16%)(Table 6.2). Over 29% of control households relied on an unprotected well, unprotected spring, or surface water, compared to only 12% of intervention households. Similar to the water source used for drinking water, a greater proportion of intervention households reported using a piped water source on the household premises for other uses, including cooking, bathing and toilet use. We tested piped water sources (n=15), when available at the time of sample collection, and none had detectable chlorine residual (Table 6.5). Fluoride and nitrates were detected in the majority of source water samples in both study arms (F: 92% v. 100%, and NO3: 76% v. 79%), though levels did not exceed the WHO guidelines (Table 6.5)[160]. Over 80% of source water samples were positive for E. coli in both study arms (Table 6.3). Average E. coli concentration was similar between study arms (4.8 × 101 cfu/100ml in the intervention v. 5.2 × 101 cfu/100ml in the control) (Figure 6.2). There was no intervention association with prevalence (aRR: 0.96, 95% CI: 0.84, 1.09) or concentration
