Thai logic at work

The mayor also said that this year a multi million-baht budget had been acquired for the purpose of connecting drainage of rain water into the city’s water treatment system pipes, leading to the water treatment plant. Both waste and rain water would be treated together for further usage. This will effectively help the swift drainage of rainwater during heavy downpours.

I used to inspect water treatment plants when I was in the US Army.

 

So you like to swim in Pattaya Bay bunky. Guess what? There are no water treatment plants designed to treat the excess water that connecting the storm sewers to the sanitary sewer system. When the heavy rains come all the raw sewage will be dumped into the bay. The sanitary engineers who designed the plant and the operating engineers must be pulling their hair out because they know what will happen. People who swim in the bay will start to get sick from all the fecal material floating around.

 

I realize the mayor is in a bind but this is not the way to do it. Properly designed storm sewer system is expensive but it's the only way to go. How will the city pay for it. They will pass a special condo tax.

Cool info - thanx for posting it, BigDUSA.

 

I believe that a simplified, parallel water-drainage system, just bellow the street level, with a few pipes that would bring it straight into the sea, would suffice and it would also be a lot less expensive...

It's a major engineering project Babe, no matter where it is.

 

I live in a small community of 4,000 and ten years ago this month we had a nearly first ever flood. The town straddles a major river, but we have dams above and below the city so we can usually regulate the flow. But a combination of heavy rains up stream with torrential local rains overwelmed the dam engineers. Re-working the storm sewer system was a multi-million dollar effort.

 

With the hills and valleys around Pattaya it will be a technically challenging effort. Take a ride down Thappraya Rd during a heavy rain and you'll see it turn into a river! Those shallow grated storm sewers down on Pratumnak Rd can't begin to handle all the runoff!

 

Let's hope the city government thinks twice about overloading the sanitary sewer system. there are good reasons they are separated in most modern cities.

Sa-teef,

I have just suggested an implementation of what I have seen in some of the [smaller] coastal towns in Croatia (and we do have a lot of coast ) - no idea how exactly these additional seweage systems were constructed, but they were put in place in some of those towns just a few years back and they didn't cost a fortune.

 

OTOH, we don't have monsoon rains and Pattaya is about an order of magnitude bigger than the towns in question...
