Cardiff LDP Hearing session 2 Constraints to development, Provision of infrastructure, Timing and delivery 

Max Wallis on  - Cardiff West Sewage Treatment capacity is over its limit

The Inspector said getting official information on forward plans (AMP-6) would be impossible.

DCWW tackled the storm overflow problem in 2010 due to too little treatment capacity (by 15%)
- needed to meet 3 spills per season (from about 50) and achieve the guideline standard at Barry Island's designated bathing beaches Whitmore Bay and Cold Knap.
They used to store peak flows in storm tanks and let these overflow untreated once full.

DCWW introduced UV of the untreated overflows from the storm tanks, giving 99% reduction in bacteria.
This met the guideline standard up to 2013, but does not meet the revised Directive. Though the Directive 
is in force from 2015, the international Blue Flag organisation agreed to implement it also in 2014 (based on 2013 data). 
The Barry beaches could not fly Blue Flags in 2014 (and dropped the dog-ban on Jacksons Bay).

This means that the Cog Moors works needs upgrading to meet the Bathing Water standard with current flows.

This report says a 15% increase in throughput and increased storm tanks is "impracticable within the constraints of the site".
    
What are Dwr Cymru's options and how soon could they deliver:
# expand on adjacent land - who owns it and what planning problems?
# need for extra capacity in the sewer and pumping from Penarth Rd pumping station?
# is the project in  in AMP6 and finance available?
