On the 19 of September 2018 the HSTP contractor arrived at
6:30 am with his bob cat and 10 Tonne excavator, and as we had already marked
out the ground he got started. The aim
was to get the hole for the Home Sewerage Treatment Plant dug by 8:30 am so it
could be off loaded and positioned. Luck
was not with us as at 500 mm down he hit rock.
|
Breaking Rock |
The contractor was prepared and had a rock breaker with him
and he started. At 8:30 am the HSTP
arrived and there was no choice but of off load it out of the way. After 8 long and noisy hours he got the hole
down to depth. We got out the
instruments and checked the depth and we all decided it was time to knock off
due to the fading light.
|
The HSTP Plant |
The next morning we started at 6:30 am by re-checking the depth,
it is easy to make a mistake when you are tired. Satisfied with the depth the contractor placed
bedding gravel and checked that the bedding was level. He finished just in time as the crane to
place the HSTP arrived, so the rigger started slinging it. By 10:30 am the HSTP was in place and back
filling was underway.
|
The Finished Excavation for the HSTP |
The next task was to trench from the HSTP to the Granny Flat
and onto the House. We then ran the
conduits and the power cable for the HSTP on one side of the trench, The HSTP contractor ran the sewer lines on
the other side of the trench. We all
stopped for some lunch and water when the council inspector arrived and gave
his seal of approval. We started
backfilling almost immediately.
|
Positioning the HSTP |
After the back filling was completed the HSTP contractor
levelled the ground where the granny flat rainwater tanks would be installed. The HSTP contractor loaded his equipment
under lights. It was a long day.
|
Part of the Trenches |
We did not get much rest as the rainwater tanks were due in
a week’s time and the tank stand had to be completed by then. A full day was needed to move all the spoil
out of the way and clean up the area around the tank stand. Both of us then spent the next day placing
the sleepers and getting the levels right.
Any error at this stage would be compounded over the next few days.
|
Framing the Rain Water Tank Stand |
The sleepers were then bolted together and one removed so
that cracker dust could be placed and compacted with our little tractor. The final sleeper was bolted in place and the
pad brought to approximate level.
|
Off Loading the Second Tank |
Using a 3 m screed and a 1.2 spirit level the tank stand was
levelled off. This was a tedious task
that took the best part of an afternoon.
The next morning the location details were checked against the council
approved plans and we used instruments to check that the tank stand was level,
which it was.
|
Positioning the Tanks |
Our tanks arrived on time.
Unloading was a basic process; some pieces of wood were placed on the
tank stand and the tanks were pushed off the truck on to the wood. The tanks slid easily on the wood so the
tanks were placed in the desired locations and the wood removed. Within an hour of arrival the tanks were in
place.
|
Tanks in Final Position |
All that was left was to install the tank fittings and put
some rain water into the tanks to ensure that they remain in place.
