REQUIREMENT

A school destroyed by fire required a temporary pumping station to discharge the waste from a large temporary classroom.

Building control required a 24-hour storage capacity in case of break down or power failure, when using pumps as the sole way of discharge foul waste.

High ground water levels limited the depth of possible excavation.

METHOD

• A longitudinal chamber was specified due to the ground conditions.
• To meet the designer’s brief, the chamber specified was 1800mm diameter by 9000mm long, offering 20,000 litres of storage.
• Twin submersible vortex pumps were installed and a new rising main was run to the main sewer system.

RESULT

• A small diameter lateral tank reduces the depth of the excavation to approximately 2.5m rather than 6m using a horizontal chamber.
• A shallow but longer excavation reduces the requirements for support structure at time of excavation where space allows.
• These packaged pumping stations come ready to install and require surrounding with concrete to anchor them into the ground.
• This pumping station is a temporary installation for two years whilst the existing school is rebuilt.
• After full commissioning by our engineers the system will offer trouble free service for this duration.
• We will supply a two-year service agreement to the client.

 

   

FOCUS ON:

 

LATITUDINAL CHAMBERS

Latitudinal chambers are an appropriate choice where ground conditions do not allow for a deep excavation. They reduce the requirement for a support structure at time of excavation.

We can offer latitudinal chambers from 1.6m to 3m in diameter and up to 16m long, with capacities up to 113,000 litres.
