Proposal Description
The existing Moordkuil Pump Station design is outdated and is not able to be maintained/repaired due to the unavailability of parts and other maintenance restrictions. It is therefore required to upgrade the raw water abstraction works and pump station with more modern technology that will be low maintenance, cost effective and efficient.
The following is proposed to be constructed:
• Construction of a new reinforced concrete inlet hopper structure for the pump station;
• Construction of a pipe protection ramp structure for the pipes into the existing pump station building.
• Reinstatement of the existing gravel access road from Blesbok Road to the site (180m long and 3.6m wide) by reinstating the existing gravel road, within the same footprint, which has become almost impassable due to water ingress into the existing layer works (farmers leaking irrigation channel). The final road is proposed to be 3m wide.
• A new concrete road (in an already disturbed area mostly). The footprint of the proposed new road is about 500m² and ranges in width from 3m to 7.4m (in order for a 5-ton truck to turn around);
• Construction of an access ramp to the hopper;
• Construction of a new water meter chamber alongside the pump station. The development footprint of the water meter chamber is approximately 20m²;
• Replacement of three air-valves and construction of new chambers around the air-valves;
• Installation of new pipework, pumps and motor control centres;
• Installation of other mechanical items such as cover, trash-racks, etc.
• Upgrading of the electrical supply and breakers within the existing pump station building;
• Installation of a sediment barrier downstream of the crossing to curb sediment generation in the river, and
• Final reinstatement of the river bed to the requirements of the CEMP;
The concrete inlet hopper structure is proposed to be anchored to the bedrock by means of piling foundations. In order to install the piles, a pile rig needs to obtain access in the correct position. It is for this reason that a temporary platform structure is required to be constructed within the Moordkuil River.
The area where the inlet hopper (and the associated pile foundations) is proposed to be constructed is below the 1:10 year floodline, within the river. It is therefore required to construct a coffer dam around the area where the inlet hopper structure is proposed to be built in order to have a dry area for construction and concrete setting.
All of the above, except for the proposed temporary platform, cement access road, new water meter chamber and sediment barrier, will be located within the existing development footprint.
It is also proposed to demolish the existing underwater cement bag wall, existing above water concrete steps and the existing underwater concrete plinths for the existing pipes.
Three alternative site camps have also been proposed, with Alternative Site Camp 1, being the proposed alternative (refer to Figures 9-23)
A Site Layout Plan showing the proposed construction activities as outline above is illustrated in Figure 19
