The Coral Bay WWTP required upgrades to increase its disposal capacity due to a recent boost in tourism to the area and for future growth planning.
The scope of works included the construction of a new 200 x 80m Evaporation Pond 2 with BGM liner, access ramp and interconnecting box culverts, a new concrete spillway in Evaporation Pond 1 for emergency overflow, a new access ramp into the Emergency Infiltration Area, sand clean-out of Evaporation Pond 1 north east corner and repair of its GCL liner, construction of a new gravel hardstand as a Geobag Laydown area with PVC pipework to allow to control seepage back into the existing Facultative and/or Maturation Ponds and the widening and upgrade of the existing gravel access roads and turning areas at the facility.
