Water Treatment. Proper water treatment for closed loop system must be integrated into the design. The system must address scaling, dissolved solids, biologic growth and corrosion protection.
Water Treatment. 6 ISSUE: Excluding the below districts, XXX agrees with Cal Water’s estimates on 8 and ORA use different forecasting methodologies. As described under District 10 forecasting whereas ORA only escalates the base amount. Redwood Valley’s Lucerne 11 and Unified Districts’ forecasts vary because Cal Water and ORA use different numbers 12 of historical years’ amounts in their respective averages for determining the test-year 13 estimate. 14 RESOLUTION: See below for district specifics. 16 Bear Gulch, Livermore, RDV-Lucerne, and RDV-Unified: Cal Water accepts 17 XXX’s forecasted amounts.

Water Treatment. DISCHARGE
Water Treatment. 5.2. The CONCESSIONAIRE is responsible for the provision of drinking water and sanitation services, including the following activities:
Water Treatment. (i) The hours of work for water treatment staff shall consist of five (5) consecutive work days from either Monday to Friday or Wednesday to Sunday of seven (7) consecutive hours between the hours of 9:00 AM and 5:00 PM exclusive of a one (1) hour meal period.
Water Treatment. The Walgett Water Treatment Plant (WTP) was built in 2014 and commissioned in the 2015 with a design capacity of 1.5 ML/day. The Walgett WTP treatment process consists of optional pre-chlorination (not normally used) coagulation, flocculation, clarification through a clarifier, and filtration through a single media filter followed by disinfection. The process also included chemical dosing for pH correction and PAC. Treated water is pumped to the 1.4 ML standpipe storage reservoir via town’s reticulation. A list of chemicals for the plant is provided in Table 8. Distribution Treated water is both pumped and reticulated through the town via gravity. Treated water not used within the reticulation system is stored in the treated water reservoir. The reservoir helps sustain water pressure for the reticulation system. Namoi Namoi Aboriginal Reserve is located approximately 2km from Walgett. The Reserve community comprises 21 houses, 1 outlying dwelling, 1 workshop and has an estimated population of 250 people (peak population of 350). The Namoi Aboriginal Reserve is supplied both potable and raw water from the Walgett water supply systems. Potable water is delivered to a bulk meter connecting to Namoi Aboriginal Reserve drinking water supply and transferred via the rising mains and reticulation systems. Raw water is delivered to the village via a separate bulk meter and pipe networks. Walgett Shire Council is responsible for suppling water to the bulk meter, while the internal reticulation is the responsibility of the Local Aboriginal Land Council. The management of the drinking water supply system within the community is subcontracted. The NSW Government Office of Water developed a Water & Sewerage Management Plan for Namoi in 2011 – as this scheme is operated by Council, the water quality issues for Namoi are the same as for Walgett.
Water Treatment. Raw water is pumped from the Barwon River and directed to the 1 ML raw water reservoir. Water is then transfer to the raw water system and directed to a water treatment plant for treatment. The water treatment process filters the raw water by continuous filtration through media filtration, ultrafiltration through membranes and granular activated carbon (GAC) filters. The media filtration is unable to effectively reduce turbidity (the turbidity of the media filtered water is 94% of the turbidity of the raw water). The following steps of membrane filtration followed by GAC filters produces water with low turbidity such that disinfection is not compromised. The filtered water is disinfected by chlorine. The water has a high chlorine demand, so at present there is a requirement to overdose chlorine (>5 mg/L) at the WTP to ensure that there is a chlorine residual leaving the water tower (there is a dedicated rising main to the Reservoir, so this practice, whilst not ideal, does not pose a health risk). A fluoridation plant has been constructed but is not in use. Treated water is then transferred to a
Water Treatment. The Lightning Ridge drinking water supply system pumps water from the town bores to the town reservoirs, via a heat exchange system with the Swimming Pool. Chlorine is reactively added manually to the reservoir to manage bacterial risks.
Water Treatment. The parties recognize that decisions regarding water treatment (such as fluoridation) may be decided by the electorate of Xxxx and St. Louis. In such event, Pine River agrees to accept and be bound by such decisions.
