Hotel beach contamination by waste water
Submitted by Dick Grimshaw on Mon, 16/07/2007 - 05:42.
I would draw your attention to the use of Vetiver Grass and the Vetiver System for treating, at very low cost, waste water from hotels located close to tropical beaches. Also for the treatment of waste water from homes and septic tanks located near beaches. This waste water contamination is significantly increased during high rainfall events when waste water and sewage is swept onto beaches and into the sea.
Vetiver grass is under tropical conditions extremely fast growing and can take up water rapidly. Often five or six rows of vetiver grass will completely dry up small waste water flows. For larger waste water flows formal vetiver constructed wetlands are necessary.
Studies in Australia have shown that the uptake of Nitrogen by vetiver is 1140kg/ha/yr compared to 800 for Rhodes grass. Similarly vetiver will take up 149 kg of phosphate/ha/year compared to Rhodes Grass 90 kg per year. In addition vetiver will reduce BODs to acceptable levels, and will take up heavy metals at rates appreciably higher than most other plants.
Vetiver hedgerows make good landscaping plants.
For detailed information I refer you to the Vetiver Network homepage at http://www.vetiver.org also to three specific papers:

It is common for beach hotels to discharge waste water onto beaches
and into the sea. There are a number of hotels in Indonesia and
Senegal using vetiver for multipurpose uses including waste water
clean up, beach frontage protection etc.
Vetiver is being used on a hotel beach front at Chennai. The growth
looks good. I suggest you contact P.Haridas at
potteka...@gmail.com
The vetiver System provides a low cost and effective means of cleaning
up hotel effluent
Here are some links:
