It was a bit overcast and chilly this morning when we woke up, but no rain is expected until Wednesday. We reached a top of 20 degrees later in the afternoon while we were driving around.
Collie River Valley Caravan Park (to give it its full name) is a lovely and quiet caravan park. The people staying here are dotted all over the site which means most have no close neighbours, as is our case also. They also have clotheslines dotted around so most can see their washing if they use the line within their area.
We heard from all the noisy birds last night and this morning – kookaburras, magpies and mournful cawing of crows.
And I got a text message from the office to say my new speaker had arrived. We picked it up on our way back to the van later.
Now that the hardware store was open, we needed to get some wing nuts as Russ lost the bolt when he changed over the battery There is only one holding the bracket down at the moment. That was our first stop.
Russ has found a bakery!!! This one hasn’t got a reputation like the Pinjarra in Waroona, but its pies and pastries are heaps better. The potato pie was much larger for starters, and the apple turnover had more apple in it as well as heaps of fresh cream. The custard cream donut was excellent.
While Russ ate his pie I went across to the Red Cross Op Shop for a look around. Of course, I found some earrings and two tops, so I was a happy camper also. I also picked up a hard cover book by JD Robb – the newest one in the Eve Dallas series – for $4. I almost swooned.
Collie’s main street is cut into two by a wide swather of parkland and car parking areas. It certainly changes things up as you only have to look one way. Some of the area also has children’s playgrounds. Lots of trees and bushes so very nice to wander through.
We decided to go back to the caravan park so that Russ could put the second nut onto the battery. It is a mongrel of a job the way they have set it up in the motor. There is a long metal rod with a curved ‘j’ on one end and the screwing section on the other end for each side of the battery case. But it has to be hooked into a circle at the base which keeps popping out as you try and put the bracket across the top of the battery and put the wing nut on to hold it in place. There was some swearing involved by both of us as we needed all the hands to make it work.
After the fiasco was completed, we decided to take a drive out into the country as the day was still relatively young. We both washed the grime off our hands and then I made up our thermoses in case of need.
We took off to see the Glen Mervyn Dam, and we travelled through native bushland. We found out it is the Newman State Forest and there were several splashes of different colours while we went past. Looking good for other days ahead.
The WA Water Corporation have 52,000km of pipeline servicing 2.6 million sq km across the state. To put this in perspective, the combined length of all those pipes would stretch around the equator 1.3 times. Think about what that means for plants and pumping power!
Located on the planet’s driest inhabited continent also means serious climate change impacts, not to mention soaring population and growing industrial demand. This means their planning for the future needs to be spot on.
WA now gets less water from rainfall than previously. So, WA Water Corp were the first utility in Australia to introduce desalination as a large-scale, climate-resilient source of drinking water.
At present there are two seawater desalination plants – one at Kwinana and the other at Binningup- which provide water security for Perth and have the capacity to supply around half of the local water needs. Looking to the future, they are investing in seawater desalination across the state.
Desalination turns seawater into fresh water for drinking, using a process called reverse osmosis. An intake pipeline tunnelled under the seabed transfers seawater from an intake head into the desalination plant.
These intakes have a screen to prevent large sea animals from entering. They are also designed to take seawater in at low speeds, similar to natural ocean currents, so marine life can swim away from the pipeline.
Then seawater goes through an initial screening to remove larger debris like sand and seaweed when it reaches the desalination plant. After this, a pre-treatment removes any fine particles from the seawater.
During the reverse osmosis process fresh water is separated by pushing the filtered seawater through membranes using intense pressure. These membranes have sub microscopic pores which act like ultra-fine strainers, removing salt, bacteria, viruses and other impurities.
About half the seawater that enters the desalination plant becomes fresh water for drinking. This water is very pure, so minerals are added to make the water safe to drink before it enters the water supply for all to enjoy.
The remaining water, known as brine, is around twice as salty as normal seawater. It is returned to the ocean through a pipeline that extends offshore to a suitable depth.
At this point, specially designed diffusers, combined with natural ocean currents and water movement near the desalination plants, disperse the brine into the ocean.
I always wanted to know more about desalination plants.
The Glen Mervyn Dam is a picturesque body of water which makes it a hub for recreational activities, including fishing, kayaking, swimming, and waterskiing. Surrounded by jarrah forests, the dam provides a tranquil backdrop for a day of adventure or relaxation. Anglers can enjoy casting their lines for rainbow trout, redfin perch, or marron (WA yabbies) during the season.
For hiking enthusiasts, the nearby Bibbulmun Track offers endless opportunities to explore the region’s natural beauty. This world-famous trail meanders through forests, hills, and valleys and provides hikers with breathtaking views and a chance to connect with nature.
We drove into the road leading to the Day Area of the Dam and followed the gravel road until I spotted a pink flower. It was a Pink Fairy Orchid, so the cameras came out.
Then we came across our first Blue Squill flower for this trip, some more flowering Clematis and, in a first for us, we came across a pink flowering sundew.
These sundews are a much lighter green almost a mossy colour, than the usual counterparts which are darker green tipped in red. It was an exciting moment for us. We take out pleasure in simple wins like this. (smiley face)
It was then time to drive back to the caravan park for a late afternoon tea, and to put on the casserole for tea tomorrow night.
Diary updated – check. Photos to edit – check.
And more adventures in the area to look forward to tomorrow.
