Water Trunkmain Programs

 

A trunkmain is defined as a main of 375mm diameter or greater. Killard Excavation Pty Ltd has installed trunkmains along trafficable roads throughout Sydney and Wollongong since 2007. Our company has installed 30.9km of mains ranging from PVC, DICL, SCL, Sintakote, and PE.

 

The bulk of our installation methods have been undertaken via the open trenching method; however, Killard Excavation Pty Ltd also has extensive experience in trenchless technologies such as micro tunneling, thrust boring, pipe cracking, and slip lining.

 

Works include all supplementary works such as connections, pressure testing, valves, hydrants and control pits, thrust blocks, and welding.

 

The value of Killard Excavation Pty Ltd's water trunkmain programs has been $30, 635, 000 to date.

 

Water Reticulation Programs

 

Killard Excavation Pty Ltd has undertaken many water reticulation projects for BCV Networks Alliance. A reticulation main is deinfed as a main of 300mm diameter or less. Killard Excavation Pty Ltd has undertaken the installation of predominately DN100 and 150 water reticulation mains within Greater Sydney region. Projects involve any type of pipe, from PVC, DICL, SCL, Sintakote, and PE, and by any means, including open trench, pipecracking, slip lining, directional drill or thrust bore.

 

53.2km of water reticulation have been delivered over the last 5 years. 34km have been by means of pipecracking, 1.8km were mains of 300mm diameter and a further 637 metres was between 180mm and 250mm diameter.

 

Water reticulation projects have taken place at locations such as:

  • Ashfield, Bankstown
  • Landy Drive, Mt Warrigal
  • Baulkham Hills
  • Kieraville, Wollongong
  • Liverpool, Sydney
  • Burwood Road, Burwood
  • North Shore Area

The value of Killard Excavation Pty Ltd's water reticulation programs has been $18, 860, 000 to date.

 

Pressure Reduction Programs

 

Pressure Reduction Valves (PRVs) are cut into existing mains to control the water flow within the main. Killard Excavation Pty Ltd has undertaken the installation of precast pits, piled anchor blocks, pipework, installation of PRVs, flowmeters, electrical conduits, kiosk plinth, and connections to 1350mm diameter.

 

The value of Killard Excavation Pty Ltd's PRVs has been $5, 800, 000 to date.

Soil samples may also be taken by the respresntative. On sections where the polyethylene sleeve has been removed for inspection these will be suitably repaired
  • Backfilling with sand around pipes and up to 150mm over pipes will commence, and backfill and compaction with excavated material for remainder of trench will be undertaken. A compaction test will be performed. A 200mm depth of topsoil trimmed and seeded from stockpile will be placed over the excavation. Excess excavated material will be stored at the stockpile for excess excavated material
  • The security fence will be removed along with erosion and sediment control measures and works will commence at the remaining excavation points
