Sustainable living: Tank water

The plumbers came yesterday to do the final stage in our project to get tank water connected to the house. Our two 7000 litre rain water tanks are now connected to a pump, some filters, and plumbed into the house water system. The tanks have a float switch which will switch us back to town water if the water in the tanks run too low. We can also manually switch back to town water if we want to, for example in Summer, if we are getting low on tank water, we might decide to use the tank water for the garden and the town water in the house (as rain water is better for the garden than town water). We don't have a flow meter on the tank system yet, but will be looking to get one soon so that we can still keep track of our water usage.

The Cunning Plans Dept did some calculations and reckons that based on our average rain fall and the collection area of the roof, tank water would be able to cover about half of our annual water usage.

Does it feel any different? Well the taste is definitely different. Rain water tastes much milder and doesn't have that slight chlorine after taste. The water pressure in the house is also less than we had with town water. This doesn't seem to be a problem, but I have noticed that obviously things like the washing machine take longer to fill. It does enforce less water usage in the shower! Also psychologically, I think being aware that you're using water from your own tank does make you think more about your water usage.

The next step will be to get the maximum usage out of our water and get a grey water system running under the backyard to water the trees and shrubs. And we'll also be looking at other ways we can reduce our overall water consumption so that tank water becomes a larger percentage of our total usage.This is the photo of us in our backyard, next to the vegie patch (with the two 7000 litre tanks on the right) that we submitted to the Alternative Technology Association's online event for the 350.org Global Day of Climate Action (this Saturday, 24th October). The ATA is aiming to get 350 photos of real people living sustainable lives. You can check out their gallery here. I like how the photos capture a wide range of things from big projects to small steps.

This saturday, if you're in the Wollongong area, why not check out the Waste Not! Vegie Swap at the Wollongong Community Garden and pop into Futureworld Eco-Technology Centre in Warrawong.

Vegie patch - now with plants!

Last weekend I finally got around to transplanting plants from the multitude of pots cluttering the back veranda into the vegie patch. And voila!

The top bed (which is the one on the left) has all the strawberry plants. I tried planting out a couple of the runners. One survived, one didn't, but the surviving plants are doing well. One is currently flowering and fruiting.

The next bed has most of the more established tomato and capsicums that I had in pots. I've also planted the basil seedlings between them. They seem to be going okay, but the leaves are going a bit yellow. Ms D has mentioned this is probably because I've mulched with lawn clippings and a bit of blood and bone should do the trick.

The next bed has some of the tomato and capsicum seedlings that were still in the seedling trays, plus the parsley and coriander seedlings.

At the end of each bed I've transplanted the pyrethrum and borage seedlings. I'm hoping these will be good companion plants and help deter bugs. Unfortunately, they're still tiny so they aren't doing much yet.

Of course, there has been one minor hitch in that the days after I planted everything into the vegie patch have turned out to be among the hottest and driest all month. I did mulch everything with lawn clippings to help reduce water loss. The smaller seedlings seem to have suffered the most. C'est la vie. I have more seeds.

However, the Cunning Plans Dept has rigged up a pretty nifty system to get rain water from our rain water tank to our garden without exposing parts of the system to unintentional "lab testing" by Hudson and Gracie (they eat hoses, hose fittings, anything really...).

The 2500L rain water tank sits down the side of the back veranda (Fig.1). The CPD then dug a trench on the top terrace to sink a pipe that runs from the tank and pops out the side of the terrace retaining wall. A length of hose then runs from the tank, through the pipe (Fig.2) and pops out the retaining wall, which is contained within vegie patch MkI (Fig.3). The hose is then threaded through the top of the weld mesh fence of vegie patch MkI (Fig.4) and at the end of the fence there is a hose attachment (Fig.5)to we can attach a hose to water vegie patch MkII. Because the tank is uphill, there is no problem with water pressure.

This weekend we bought some weeper hose to put under the mulch in the vegie patch as the main irrigation system. This will probably involve burying a pipe between vegie patches 1 and 2 so that we can leave the irrigation hose connected and just turn it on and off from the tank.

The other plants are doing well. The first sunflowers have finally opened. The marigolds are in bloom. They are incredibly cheerful looking flowers. The bonus compost tomatoes out the front appear to have both romas and regular tomatoes.

We have tomatoes

Well the beginnings of tomatoes at any rate. The first rouge de marmande tomatoes have just started to form.

My tomato leaves are being eaten by little green caterpillars. This weekend I practiced one of the organic methods of pest control, i.e. sat down next to the plant, turned every leaf over and squished the little buggers. I'm thinking about getting some pyrethrum plants, both as companion plants and so I can make a spray from the flowers to keep the bugs down. Also got some whitefly, but they don't look like they're doing much damage.

This weekend saw a lot of transplanting. The capsicum seedlings have been transplanted into seperate pots. The thyme and marjoram have been transplanted into the front garden. And a couple of rosemary cuttings that had started to put out roots after sitting in water on my window sill have been transplanted into pots. The strawberry plants continue to do well, though I wish they'd produce more!

Something the Cunning Plans Dept did a few weeks ago was transform an old wine barrel that we picked up a few years ago into a water tank for the front garden. I finally remembered to take a photo as it is kinda neat.

There is a diverter on the downpipe, which goes into the hole that was there when we got it. The CPD has added a tap at the bottom. Unfortunately, the wood has been so dry for so long that it isn't swelling enough when wet to seal, so we're probably going to have a put a liner in it to make it more useful. We've also ordered a commercial rain water tank to put down the side of the house for more serious water storage.
