This is the original artical regarding soakwell Myths and Information.
There is a large amount of false information which surrounds the topic of soakwells.
1. First untrue statement -“It is law to have soakwells” This is untrue as various other stormwater systems exist that retain water on site, such as rainwater tanks. Additionally while some councils do recommend soakwells, some councils have no recommendation regarding soakwells such as the City of Joondalup regarding residential properties. However, if a stormwater drainage system is not installed, it becomes more difficult to defend your home against flooding, soil erosion and rain damage. It also becomes more challenging to prevent your water from flowing into neighbouring properties. Essentially we still recommend soakwells in most soil types, however, it is best to consult your specific property and building plans as well as your council recommendations to determine your appropriate stormwater drainage system.
2. Second untrue statement - “One soakwell per downpipe is inadequate” This statement is false and uneducated. If your property does not require a drainage system, then any additional stormwater implementation would be beneficial, regardless of size, volume or material. Additionally, the adequacy of one soakwell per downpipe can only be determined by the size of the soakwell, the soil type and amount of water expected to be flowing down the particular downpipe. A general rule of thumb is that a single 175 litre soakwell services an estimated 17sqm of impermeable area in sandy soil.
3. Third untrue statement “PVC soakwells are inadequate” This statement is untrue as our own premium polypropylene soakwells drain 40% more efficiently than a concrete soakwell of the same size. Most councils do not specify materials, only volumes.
Beware of uninformed installers who attempt scare tactics on the trusting client.
