Package pump stations designed around the site

A reliable installation starts with the correct flow, pumping head, storage volume, discharge route, controls and access for future maintenance.

Alton Facility Services supports domestic, commercial and development pump station projects across Hampshire, Surrey, West Sussex, Berkshire and nearby areas.

Package pump stations, also described as packaged pumping stations, combine a chamber, pumps, internal pipework, valves and level controls into a coordinated system for sites where gravity drainage is not practical.

We assess the incoming flow, site levels, rising-main route, discharge point, electrical supply and access before recommending a chamber and pump arrangement.

Our scope can include excavation, base preparation, chamber installation, pumps, internal pipework, valves, control panels, high-level alarms, electrical coordination and commissioning.

For faults, alarms, servicing or refurbishment of an existing station, use our dedicated pump station repair and servicing page.

For specialist pump work, our sister company Alton Pumps provides package pump stations.

Design and pump selection

Flow, head, storage, pump duty, control philosophy and rising-main requirements are reviewed before installation.

Civils and chamber installation

AFS can coordinate excavation, concrete bases, chamber placement, drainage connections and reinstatement.

Controls and commissioning

Pumps, floats, probes, alarms, valves and controls are tested before the system is handed over.

Our pump station installation process

Survey and duty review

We confirm site levels, flows, discharge point, pipe route, power supply, access and future maintenance needs.

Specify and quote

We set out the chamber, pump arrangement, controls, alarm, pipework and civil works included in the proposal.

Install and commission

The system is installed, connected, tested and commissioned with practical maintenance advice.

What a package pump station can include

The correct equipment depends on the liquid being pumped, the expected duty and the consequence of failure.

Systems may use single or duty-standby pumps, depending on flow, storage and resilience requirements. Commercial and higher-risk sites often require twin pumps, alarm outputs and more detailed control arrangements.

AFS considers the complete pumping system rather than selecting a pump in isolation. Chamber geometry, free passage, valves, guide rails, lifting arrangements, rising-main velocity and access all affect long-term reliability.

Typical installation components

  • GRP or polyethylene pump chamber
  • Single or duty-standby submersible pumps
  • Guide rails, pedestals and lifting chains
  • Isolation and non-return valves
  • Control panel, level controls and high-level alarm
  • Rising main and discharge connection

Civils, drainage and rising-main coordination

A pump station installation normally involves more than supplying the chamber and pumps.

AFS can coordinate excavation, formation preparation, concrete surround or anti-flotation measures, inlet drainage, valve chambers, ducting, rising-main installation and reinstatement where these are included in the project scope.

Where approvals or third-party connections are required, the final design should reflect the relevant water-company, drainage, planning and electrical requirements.

Suitable applications

  • New houses, extensions and annexes
  • Commercial buildings and managed estates
  • Basements and below-ground facilities
  • Sewage treatment plant pumped outlets
  • Surface water and groundwater systems
  • Developments where gravity drainage is not possible

Single-pump or twin-pump package station?

The number of pumps should reflect the design flow, storage, operating risk and the consequence of a failure.

A single-pump station may be suitable for some lower-risk domestic applications where the duty, storage and maintenance plan support that arrangement. It does not provide an installed standby pump if the duty pump is unavailable.

Twin-pump stations can provide duty-assist or duty-standby operation. The controls, alternation, alarm strategy and usable storage still need to be designed correctly; adding a second pump does not compensate for an unsuitable chamber or rising main.

Selection factors

  • Design flow and peak inflow
  • Static and friction pumping head
  • Usable emergency storage
  • Consequence of pump failure
  • Duty, assist or standby operation
  • Maintenance and emergency access

Domestic, commercial and development pump stations

Packaged sewage and drainage pump stations are used wherever the receiving point cannot be reached reliably by gravity.

Domestic applications include houses, extensions, annexes, basements and rural properties. Commercial systems may serve offices, hospitality sites, managed buildings, yards or operational premises with higher or more variable flows.

Development projects may require coordinated drainage levels, adoptable or private-system requirements, electrical design, access for tankers and lifting equipment, and clear responsibility for ongoing maintenance.

Common applications

  • Domestic sewage pumping stations
  • Commercial foul-water stations
  • Basement drainage and groundwater
  • Surface-water pumping systems
  • Treatment plant pumped outlets
  • Small developments and converted buildings

Information needed for pump station specification

Useful project information reduces assumptions and helps establish whether a survey or design review is needed.

Send the proposed use, site address, drainage layout, incoming pipe level, discharge point, rising-main route, expected flows and available electrical supply where known.

For a replacement or upgrade, include photographs of the chamber, pumps, control panel, valves, alarm and data plates together with service records or previous drawings.

Send with your enquiry

  • Site plan and drainage drawings
  • Incoming invert and discharge levels
  • Expected flow or property usage
  • Rising-main length and diameter
  • Power supply and control requirements
  • Access, groundwater and excavation constraints

Package Pump Stations FAQs

When is a package pump station required?

A package pump station is normally required when drainage cannot reach the receiving sewer, treatment plant or outfall by gravity.

Can AFS undertake the excavation and civils?

Yes. Subject to the agreed scope, AFS can coordinate excavation, chamber installation, drainage connections, rising mains, bases and reinstatement.

Do you install duty-standby pump stations?

Yes. We can specify and install twin-pump duty-standby arrangements where resilience, flow or site risk requires them.

Can you design the pump duty?

We review flow, head, storage and site conditions and work with the selected manufacturer or supplier to confirm a suitable duty and system arrangement.

Do you repair existing pump stations?

Yes. Existing faults, alarms, servicing and refurbishment are covered on our dedicated pump station repair and servicing page.

How much does a package pump station cost?

The cost depends on design flow, pumping head, storage volume, number of pumps, chamber depth, rising-main length, controls, alarms, excavation, access and reinstatement. Send the site layout, levels and expected flows for an initial scope review.

How long does package pump station installation take?

Programme length depends on design information, approvals, equipment lead time, excavation, groundwater, services, access and commissioning. AFS can outline the likely stages after reviewing the site details.

What is the difference between a single and twin pump station?

A single-pump station has one duty pump. A twin arrangement may provide duty-assist or duty-standby operation depending on the controls and design. The correct option depends on flow, storage, risk and the consequence of failure.

Can AFS review a supply-only package pump station enquiry?

Yes. Send the required duty, site layout, levels, rising-main information, liquid type, controls and access details. AFS can confirm what further information is needed and whether supply-only or a wider installation scope is appropriate.
