External works consisted of the following:
Internally works consisted of the following:
Works began with the removal of the existing roof overburden and membrane system plus excavation of perimeter trench to allow application of new Premseal waterproof membrane to the roof and perimeter upstand wall with an Aqualine band to seal the roof/wall joint.
The new drainage system was then installed from the reservoir roof with 2 new soakaways. Also 2 new concrete access hatches with high security access covers were constructed, each one leading into each compartment of the reservoir. The roof will then covered with deckdrain and the overburden reinstated. New steps to the reservoir roof were re-constructed with a new handrail installed.
Internally we completed concrete repairs to the soffit where the existing concrete has spalled away from the steel reinforcement. The soffit panels were then skimmed with Sika 107. The existing division wall was extended to the full height of the reservoir by removing the existing concrete coping and casting a new 400mm thick concrete wall. Due to the construct of the full height division wall the existing staircase access is to be removed and the access sealed as part of the works.
