Civil Case Study: Pumpstation for 102 Lots in Manurewa

Application

Site: Mahia Road, Manurewa, Auckland.

This pumpstation was designed, manufactured & assembled inhouse before being delivered to site in one piece.
The pumpstation was for a small land development project in Manurewa of 102 lots where space available was very limited. The pumpstation site backs onto the Manukau harbour, so design and emergency storage calculations to prevent overflows were paramount.

Solution

Our team worked with Candor3 Consultants with the design of this pumpstation; the wetwell and integral valve chamber were manufactured from fibreglass and all pipework was pre-fitted in the factory before being delivered to site ready for the civil contractor to lower into the ground.

Wetwell size: 3.0m dia x 5.0m deep
Pumps: Xylem NP3085 2.4kW
Pipework: 100mm 316 Stainless Steel

Product Used

Municipal Packaged Pump Stations

Fluidtec package pump stations are ideal for use in residential and commercial subdivisions where a gravity connection is not possible.
They are supplied to site fully built up complete with pumps, pipework, valves, control gear, pump protection, lids, inlet pipe and tank.
Constructed from fibreglass the tanks are custom designed on a case by case basis and are able to be installed at depths of 12m deep. Standard pump station diameters are:

  • 1200mm
  • 1500mm
  • 1800mm
  • 2100mm
  • 2500mm
  • 3000mm
  • 4000mm

Custom diameters and builds are also available.
These units have an integral valve chamber making installation much easier.

Custom diameters and builds are also available.
These units have an integral valve chamber making installation much easier.

Fluidtec Packaged Pump Stations are factory designed, built and assembled in our manufacturing facilities and are delivered to site ready to be lowered into the ground. Compared to a conventional concrete pump station typical onsite site work is thus restricted to:

  1. Lowering in the one-piece pump station (valves and pipework are already installed)
  2. Connect the outlet pipe with single flange
  3. Lowering the pumps down (only because we cannot transport the pump station with them)

 

Note we will have a picture of the pump station here as a cutaway showing the below points:

  1. Integral valve chamber – easy installation and simple valve removal
  2. One piece Fibreglass tank – zero infiltration, lightweight, designed for complete immersion and impervious to H₂S corrosion.
  3. 60° sludge batter incorporated into the base of the chamber to prevent solids build up
  4. Hinged safety grate under the wet well opening
  5. Preassembled pipework from the pump auto-coupling to external discharge flange
  6. Dismantling elbow – simple valve removal
  7. Tank internals have a white gelcoat coating enabling easy cleaning and also making visual inspections easy.

Where you need to design/install a pumping station for project where the Council will take this over, please consider
one of our FRP Package Pumpstations.
Typical applications are:

  1. Residential Developments
  2. Commercial / Industrial Developments
  3. Retro-fit / upgrade existing pumpstations
