However they continued to have the closures problem and started a testing program to identify the source where previously they had just assumed the culprits.

What they found was that many of the older houses built on the rocky headland at the river mouth had septic tanks but because the ground was rock they had no seapage disposal from the tank outflows which were just drained into the kerbside gutter.

In normal use the retention time in the septic tanks was sufficient to treat the effluent but because the roof drains on the houses were also tied into the tanks, they all flushed into the kerb side drains and from there into the main storm drain and into the river when it rained.

So is was not the yachties discharge which caused the problem but the sub standard plumbing on the older houses, although the yachties probably contributed.
while we as a general population cruisers are an easy target . Due to us not being a ( many times ) part of the local voting body.

Please visit your local pumpout.

Instead of dumping into your local waters is what I'm saying

A direct deposit here and there like the animals do is much better than some "person" dumping 20 gallons or more of crap in one spot in slow moving shallow water
Is there a magical barrier in place to stop that water crossing the line?

We have two treatment plants onboard so am not poo concerned.

And no local pump out facility, not that I am aware of.

you know the answer to your question .

Also why do you think they have the 3 mile min limit. The sewage from yourown boat will be well and truly dispersed as well as the pathogens will be killed by the UVC long before it could possibly travel the distance and sicken the general populace.

At least you're treating your waste before dumping overboard

I notice that some of these onboard treatment units use chlorine bleach to do the sanitizing. Even though it's massively diluted and probably does no harm I'm more uncomfortable with dumping chemicals into the environment than I am with raw sewage.

Sodium hyprochlorite or liquid chlorine must be used. This can be obtained from your local hardware of pool shop. The low level chlorine indicator will indicate with approximately 1L left in the tank. It is recommended to top up using 5L at a time. The chemical must be replaced if the vessel is not used for long period of time

my last boat had a type 1 electrasan system . All it needed was electricity to sanitize .


The process starts with salt water in the treatment tank.
NaCl –> Na Cl- Sodium Chloride is a strong electrolyte so it
exists in water as sodium and chloride ions.

H2O –> H OH- Through hydrolysis, water breaks into hydrogen
ions and hydroxyl ions.

The electrode pack is energized during the treatment cycle and electricity passes through the conductive salt water. Hypochlorous acid, a powerful bactericide and oxidizing agent, is produced on the surface of the plates.

At the Anode:
2Cl- OH- H –> HCl HOCl 2e- Hydrochloric acid and hypochlorous acid are produced, liberating two electrons.

At the Cathode:
2e- 2 H 2Na 2OH- –> 2 NaOH H2 The two electrons, hydrogen ions, sodium ions and hydroxyl ions combine to produce sodium hydroxide and some hydrogen.

The Net Reaction is:
2Cl- 3OH- 3H 2Na –> HCl HOCl 2NaOH H2
With constant mixing from both motors, the products are mixed together for continued reactions.

NaOCl H2O –> NaOH HOCl Hypochlorous acid (HOCl) is formed when sodium hypochlorite reacts with water.

HOCl XXXX –> HCl XXXXOx Hypochlorous acid reacts with soil, dirt, and bacteria giving up its oxygen; leaving hydrochloric acid.

HCl NaOH –> H2O NaCl The hydrochloric acid reacts with the sodium hydroxide to form salt and water.

I have a feeling the chlorine liquid will have a similar end result of being inert when actually discharged.

Re: How seriously is the 2M dumping policy enforced? (Yet another poo question)

I read in the local paper today that Carnival Cruises is in trouble again for dumping 500,000 gallons of TREATED sewage in Bahamian waters. It’s ironic given that there are zero pump out facilities in most of the country and hundreds if not thousands of boats. It is also unlikely that all of the smaller islands, private or not have treatment facilities.
