WATETANK

Catchment & Water tank Construction

-Because the large rainfall that occurs throughout the area

-Installing a Water tank is a definite solution

Catchment calculation

determine possible total roof catchment

Proposed possible roof total area
=432.00

432.00 (total area) x 1.29 (Slope factor)
=557.28

=557.28 (total roof catchment area)



Downpipe size and location

From table 3.2, in AS3500.3.2 and HB114

The minimum size downpipes compatible with Spouting of 6125mm2 cross sectional area (Installed at a 1:500 gradient) are 90mm diameter round or 100 x 50 rectangular. I selected the 100 x 50 rectangular downpipe.

From figure 3.6 AS3500.3.2 and HB114

The Maximum catchment per downpipe is 47 m2

Determine existing water usage patterns, and advise on additional water saving measures if required.

Firstly, work out the average rainfall (mm) per month

653.2 (Total mm/ per year) / 12 (months)

=54.43 (mm per month)

Then work out the amount Litres of water used on average each month

Rainfall (mm) x Catchment Area (m²)

54.43(mm) x 172.457(m²)

=9386.83L (per month)

To work how many litres we used on each section

The average Victorian urban Household consumes 210,000L per year

210,000 (litres per year) / 12 (months)

=17500 L (per month)

Garden Use = 50%= 17500/ 50%= 8750 L (per month)

Bathroom = 10%= 17500/ 10%=1750 L (per month)

Hot Water = 15% = 17500/ 15%=2625 L (per month

Toilet = 10% = 17500/ 10%=1750 L (per month)

Laundry = 10% = 17500/ 10%=1750 L (per month)

Kitchen = 5% = 17500/ 5%= 875 L (per month)

260 L Everyday

Example: 4524 (Balance in Tank) + 3687 (Yield From Fortnightly)

8211 – 4030 (Usage L)

4181 Balance in Tank

RESEARCH

HISTORY RESEARCH

-In early 1877 a small ship set sail and reportedly was missing, until the remains of an unidentified wreck were found near Lorne and throughout the Ocean Grove after some floating spars at Louttit Bay attracted attention and what was thought to be a hull was sighted floating bottom up off Mount St. George. "There was some excitement in October 1877 when unidentified wreckage came ashore at several locations. Fishermen found wreckage at Mount St George near Lorne; a portion of deck 40 feet long by 27 feet wide, with deck house attached was washed high on the beach west of Apollo Bay and the side of a ship about 40 feet in length came ashore at Castle Cove west of Cape Otway. None of it was ever identified" (Loney, 1989: 42) refer to national shipwreck database.

-Small fisherman ships washed up ashore and removed throughout Australia.

DOMUS GROUP PROJECT

SITE ANALYSIS AND ALLOCATION

















-The group selected the Bells Beach location because it close proximity so we had ability to check the site on the spot and calculate the dimensions, soil type, wind, contours accurately etc. also to first hand visit local contractors and labourers for materials and concepts
