Re: Diving into murky waters (Letters, Dec. 5).
I would certainly question the credibility of the writer. The current Atlas was published in 1983 and demonstrates strong tidal activity off Victoria.
Based on this, the Capital Regional District extended the Macaulay Point outfall to take advantage of the current pattern and avoid back eddies.
They then added diffusers so that the screened sewage, with toxic chemicals removed at the source, is discharged into a strong tidal action, where it is naturally oxygenated and thus biologically acceptable.
This has been proven by our very competent scientific monitoring.
To perform the same on land requires large amounts of power and thus is not ecologically viable.
