Tuas WRP is to be located in the west of Singapore and will have the capacity to treat an average dry weather flow
of 650 Mega-litres/day of domestic and 150 MLD of non-domestic used water collected in distinct deep tunnels and conveyed by gravity to the mega treatment facility.
Among the unusual challenges posed by the project is the sewer's significant average dry weather flow
of 50 million gallons a day.
RUN-OF-THE-RIVER Hydroelectricity is ideal for streams or rivers with a minimum dry weather flow
or those regulated by a much larger dam and reservoir upstream.
Toxicity of dry weather flow
from the Santa Monica Bay Watershed.
Two existing combined sewer regulators that divert dry weather flow
to the interceptor sewer and the associated piping were relocated beyond the roadway pavement limit; this was necessary to avoid traffic interruption during regulator maintenance operations.
The innovative Moonlight State Beach Urban Runoff Dry Weather Flow
Treatment Facility in Encinitas, California, opened September 20 with a ribbon cutting ceremony and dedication.
Thornhill said one interesting aspect of the project was that early inspection data identified many pipe sections where the dry weather flow
significantly differed from the dry weather flow
predicted by the model.
The plan is ranked according to areas that fail to meet 1) existing 2000 wet weather flow conditions; 2) predicted 2010 dry weather flow
conditions; and 3) predicted 2010 wet weather flow conditions.
The studies will include preparation of an up-to-date automated mapping system, characterization of the city's CSO discharges and dry weather flow
, and assessment of user charges billed to the city by the Passaic Valley Sewerage Commission (PVSC).
