Additional Project Information
New Settlement Tank & Upgrade Works
The new settlement tank in conjunction with the two existing settlement tanks was constructed capable of treating the total design flow of 40,600m³/day. This equates to a flow of 156.6l/sec through each of the three tanks. The settlement tank constructed incorporates
- A lamella plate system.
- Complete inlet distribution system including the raw water inlet laterals;
- Complete clarified water collection system;
- Access bridges / platforms
- Pumps, Pipework, Valves
Rapid Gravity Filter Units
Four new rapid gravity filter units (6,480m3/hr each) (28m2 each) were constructed as part of this contract along with the upgrading of the 4 existing filters (3,670m3 each) to achieve the required flow. The new filters incorporate a combined air and water washing system.
Sludge Handling Facilities
The existing sludge handling and treatment facilities were upgraded at theTourmakeady Water Treatment Plant site for dewatering of the process sludge’s from the additional settlement tank sludge bleeds and filter washwater.
