This is te prevent animals and bacteria frem entering the tanks and centaminating the water supply. This is the mest prebable seurce of centaminatien in the system at East Alligater. The tanks sheuld be checked fer pessible animal entry peints and these points should then be sealed. This sheuld alse be done en any occasion that reutine bielogical menitering detects a celiferm ceunt .of greater than 10 ceunts/100 mL. Relecatien .of Storage The 60 kL 9alvanised steel tank near Merl 1 camping' area is net being utilised to its full capacity (see Sectien 3.5) . It is recemmended this sterage be relocated te adjacent the treatment and pump house so it can previde sterage for Obiri. This also remeves the need for the diesel pe'W'ered beester pump, and makes maintenance .of the tanks much easier. The estimated cost to move this tank is $10,400. Remeyal of Diesel Sterage at Berefield Storage of diesel at a borefield poses a high risk of groundwate:~ centamination. The diesel generater and diesel storage tanks should be removed from this' borefield. It is recommended the bores be run from the main district centre generator near the pump house. The cost te reticulate power frem the main gene,rator underground to the bores and provide automated contrel of the ber'3s from the water tanks, is $63,000. Operatien Q.f Beres Pewer facilities sheuld be provided to enable RN 23449 and RN 23450 te operate tegether. This will accemmedate the peak demand perieds. This pewer sheuld be provided from a generator away frem the borefield, to remeve the
