Currently a repeat of yesterday in Chaguaramas

[Duane 3NE 2NR]

Flooding in Union Hall San Fernando
Flooding is ongoing along the Golconda Connector Road near VMCOTT. Roads are still passable. Expect traffic delays. Proceed with caution.

[redmanjp]

rain again in POS, the warning from met office still in effect

[shake d livin wake d dead]

Yesterday part 2?

[snypaz]

Laventille is flooded again. Don't come down the EMR.

[*$kїđž!™]

Met office say it would end at 2pm...but it now started in central....MET office never gets it right.

Who really going lavantille bro...lol..

If it doesn't apply to you, Move along.

[KM_2NR]

PoS rainy AF right now , bracing for the worst again.

[tr1ad]

and it has started with flooding downtown etc

[shake d livin wake d dead]

Epic traffic in the capital....lights by the lighthouse not working...reach home safe people

ODPMTT Aug. 14 2018 3:45pm - There are numerous reports of flooding in the San Juan/Laventille Region including the Barataria Roundabout, near Maritime Plaza; Morvant Junction; Don Miguel Road/Churchill Roosevelt Highway, in vicinity of VMCOTT. Persons are advised to delay travel by 1-2 hours in affected areas and to avoid intentionally driving or walking in flood waters. Persons should seek alternative routes, if possible and expect traffic delays. news.gov.tt Ministry of Works and Transport Trinidad & Tobago Ministry of Rural Development and Local Government Ministry of National Security Trinidad & Tobago

What a day to have been home!!! Takng in a light drizzle from comfort of my house.

ROFLLLL

[rspann]

Don't even attempt to pass through Saddle rd Santa Cruz to the Croisee. Flood and debris like that. Standstill traffic too.

[redmanjp]

Adverse weather warning cancelled

[hydroep]

How ironic is this?...

[Dizzy28]

How ironic is this?...

Turbidity!!!

[sMASH]

only two real problems possible with thier system. is either the incoming screens or filters are being fouled more frequently than normal, the solution would be to clean respective screens/filters more frequently.
the other is the actual treatment system having a lot more than could be handled.

that solution would be to dilute the incoming turbid water to a concentration where it wouldnt overwhelm the systems.
so, for example, if the system could process 100 m3 of water per minute, at a specific turbidity, and the turbidity quadruples, then only take in 25m3 of turbid water and and 75m3 of clear water to keep the systems running.

well the output will be reduced. duh.
then u will have to study how much turbidity u will experience in the futre and retrofit ur systems to handle it.


but, a we need to evaluate the cost to treat this heavy silted water compared to the cost of desalinating water.
which ever is cheaper, we should do that... factoring in higher natural gas prices in the future.

[redmanjp]

No water due to too much water

[rspann]

What about settling ponds ? Or dams , and pull the intake when it settles?

They use a set of screens to keep debris out. Thats what they mean. It keeps out large objects like bottles, branches etc.
The raw water is pumped in where a polymer and coagulant is added. It mixes there due to turbulent flow and then moves to a settling tank where the particles form flocs and settle out. Cant dilute the influent.

Water is filtered with a sand filter. Has a rapid sand where water is forced through it amd slow sand where gravity flow is used.

Nowhere on the plant uses a filter to remove turbidity. Turbidity is removed via coagulation, floccolotion and sedimentation.

[sMASH]

well, they need to expand their flocculation process

[nervewrecker]

I don't think they meant turbidity in the memo though.

Only way I can see water becoming more turbid is if they getting run off from quarries and bare land.

Either way the system is very capable of handling the load..

[sMASH]

the water like ovaltine. thats as turbid as u can get before u have to call it particulates.
but during these heavy rain events, u get a lot more debris, sediments, turbidity and ionic impurities... they need to expand their treatment capacity to deal with all of this and not get overwhelmed.
... and i want to think that the feasibility studies will prove that the amount of extra fresh water treatment to deal with this, may be significantly more than desalination for the comparable production.

Not even hinds going there ..again

[shogun]

Wow.

Was wondering how uber stanced/cambered men navigate weather like that, without having a few submarine mods?

[zoom rader]

This happens when a PNM governments is not prepared to clean waterways.

this happened under the yellow time as well
