Some of you may remember I asked the question on how to clean/steralize my very dirty/rotten dam water.<br /><br />Well I went through all the advice and suggestions you gave and put together a plan.<br />I them rang the Local Water Authority and asked if they would mind commenting on the suitability of the 'plan', and they said yes, and not only approved my suggestions but told me the rates etc that would be suitable.<br />(normally they suggest you go to a consultant, and then put their plan forward for approval)<br /><br />This is what I am going to do<br /><br />1. attach a "strainer" to the foot valve in the dam. This removes all but disolved clays and some sand particles. $110<br /><br />2. pump water into a tank, running it through a "disk filter" with 'red disks' (colour denotes degree of filtration). This removes "all particles", down to a grain of sand. $190<br /><br />3. Use alum or polymer (alum easiest/cheapest to buy) by mixing, throwing on top of tank water and<br />circulating for short period. All sediment will sink to bottom. Cheap.<br /><br />4. Decanter into 2nd tank, dosing with liquid chlorine at rate of 5 parts per million, or for super shock, up the dose rate. 50c per litre, Under $2.00 for 6,500gals.<br /><br />5. Dump sludde in 1st tank.<br /><br />4. Repeat<br /><br />Pointers the engineer gave me. Buy chlorine from a pool-shop that sells a lot of chlorine (always fresh) as you need min 10% chlorine. Usually leaves factory at 16%.<br />This is the cheapest and most reliable way of treating water.<br />Chlorine is like a bolt of lightening on 'bugs' but sediment must be removed from water as some bugs may be shielded from chlorine.<br /><br />I have bought a new 6,500 gal tank, plus I have the 5,500gal one and another 2,500gal one, so I will be ready to roll soon.<br /><br />As a side note, I had one consultant try and sell me a $12K Ozone machine, another a blue-light machine for $5,000. Geeez, there are some cowboys out there.<br /><br />Thanks for your help everyone.<br />Cheers<br />Phillip
