#agtwitter day 10 update at @Butterfieldbeef dam liner installation. Ran out of f plastic today 👎🏻. Emergency trip to perth to grab another roll should be done tomorrow . Installers reckon we have gone from 47000m2 to 55000m2 ,that must mean more water #winning

In Eyre Peninsular SA after long dry season talking desalination & looking at unconventional water sources. Seen several plastic sheeted catchments -2ha with 10 ML dams $100-200k built by #WaterSmart farmers @NikCallow

@trout_86 @NikCallow I heard as low as $4-6/m but likely excluding installation and only 1mm. No measure of tyre degradation mentioned. UWA did some micro plastics on tarps, its there, but impacts inconclusive

@HydroFire60 @NikCallow Any idea of cost of plastic per M2? Thinking of lining a catchment over here in WA. Also any issues with contamination with tyres being used as the weights?

@HydroFire60 @jtelferoz @NikCallow I'm guessing the empty ibc and 110 drums are to minimise wind movement over the water and therefore evaporation, but do they pose a significant rub risk to the liner?

Last day with farmers in Eyre Peninsula at Warrminda with @jtelferoz + 24 farmers talking water, salinity and WaterSmart farms. Impressive lined catchments being adopted to collect high quality and secure water despite availability of SAWater pipes nearby. Great group @NikCallow

Spent a few days measuring subsoil drains last few weeks, removing excess water from crops in GtSthn & SW, to understand opportunities for water management. Two examples running well after strong rains @NikCallow

@HydroFire60 @NikCallow Nice. 2ha need 500mm at 100% yield to fill 10ML dam. What's est lifespan of plastic?

Last @WaterSmartFarm projects 89m deep bore being tested at 150,000 litres per day near Kojonup. Over 50% rate of success for bores of similar depth and salinity - from Merredin to Manjimup.

@DPIRDWA⁩ Water science team testing 2nd last bedrock drill hole (20 drilled) from Merredin to Manjimup (this site) to find water for agriculture. Yields average over 80kL/d from depths to 100m, stock quality or ready to Desal as part of #WaterSmartFarms

@Tedthekelpie Nup, been increasing for a long while… and modelling suggests that it will continue

Our 2nd largest reservoir after Lake Argyle, Wellington Dams water quality is now almost 1500mg/L, feeding hundreds of SW farms. After 50 years of testing revegetation is it time for tools like desalination?

@WaterSmart Farms project on desalination and new farm water supplies won a 2024 AWA Award. DPIRD led consortium engages with 3 WA Uni’s, 4 Agencies, GGA, 2 RDCs, and delivers with 63 participating farmers, 3 rural towns & Wongutha school. More to do, but getting results.

@Iain78225333 V-notch weirs & data logging if the flow is variable but at higher flows ultrasonic flow meters ($). Mechanical ones need a head and hard in drains, especially when they get sediment issues. Buckets… simple

@HydroFire60 Richard whats the most accurate automatic measuring device from tile drainage. Ive been manually doing it but want to automatically quantify larger systems

Not a dollar spent in 20 years as this and another line discharges dry sheep quality water from a hillside seep #gravitysiphoningsalt

Recharge control of low production, wind-scalloped leaky wodjil sandplain is possible with targeted plantings. This one is a private carbon model that mitigates much of the farms emissions and along the way has seen an amazing regeneration of nature
