Wastewater Pump Stations Auckland

When a house sits below the public sewer, gravity cannot carry wastewater away, so it drains into a sealed tank with a pump that lifts it up to the network. You will find these private pump stations on low sections, sites that fall away from the street, basement flats and some newer subdivisions. While the pump runs nobody thinks about it. When it stops, the tank fills, the alarm sounds, and you have a limited time before wastewater backs up.

Cheeky's Plumbers services, repairs and replaces private pump stations and sump pumps right across Auckland. Our certifying drainlayers handle the drainage side, and we work through floats, alarms, check valves and rising mains until the system is pumping reliably again.

Pricing: quotes are free, and every job gets a fixed price before we start, so there are no surprises on the invoice.

Signs your pump station needs attention

Most pump stations give some warning before they fail. Call us if you notice:

• The high-level alarm light or buzzer going off
• The pump running constantly, or cycling on and off every few minutes
• Humming with no water moving, or a grinding noise
• Sewage smell around the lid or vent
• Toilets and showers draining slowly with no blockage found
• The circuit breaker tripping when the pump starts

What usually goes wrong

Float switches are the most common failure. They tell the pump when to start and stop, and once they stick, tangle or fill with fat, the pump either never starts or never stops. Next is rag build-up: wipes, sanitary products and paper towels wrap around the impeller and stall the motor. Watercare notes that these private systems can be damaged by non-flushable items, which is one reason the owner, not Watercare, is responsible for them.

Other common faults are failed non-return valves letting the rising main drain back into the tank, corroded cables and control boxes, and pumps that have simply reached the end of their life. A pump that works far harder than it should can point to stormwater getting into the tank, which needs to be found and sent to stormwater drains instead.

How It Works

Who is responsible in Auckland

On low-lying sites, Watercare sometimes approves pressure wastewater systems, where each house has its own grinder pump feeding a small pressurised main. Watercare's guidance is clear that the onsite grinder pump is owned and maintained by the property owner, with Watercare ownership starting at the boundary, where a boundary kit lets the pump be isolated. The same applies to an ordinary private pump station pumping to a gravity sewer: everything on your side is yours to maintain.

Watercare's guidance also says the storage tank should hold at least 24 hours of wastewater for a power cut or maintenance, and that in a long outage the wastewater has to be tankered away. If your power is off, use as little water as possible until it is back. New pump stations are only approved where gravity is not practical, so if you are planning a subdivision or extension, talk to us early about drainlaying options.

Sump pumps for stormwater

Not every pump handles sewage. Sump pumps lift stormwater and groundwater out of basements, sunken courtyards, retaining wall drains and driveways that fall towards the garage. They suit Auckland's sloping sites in places like Titirangi, Remuera and the East Coast Bays, where water collects at the low point of the build.

A stormwater sump pump must discharge to the stormwater system, never to a gully trap or the sewer. Watercare points out that stormwater entering the wastewater network can overload it and cause overflows. We size sump pumps for the catchment, fit a float and, where it protects a living space, an alarm.

Servicing, repair and replacement

A service covers lifting and hosing the pump, clearing rag from the impeller, testing floats and the alarm, checking the non-return valve and isolation valves, inspecting cables and the control panel, and looking at the tank for cracks and fat build-up. Annual servicing suits most homes; busier systems such as flats or a home business may need it more often.

When a pump is beyond repair we replace it like for like, or upgrade to a better-suited pump or a dual-pump arrangement where the load justifies it. If the tank needs pumping out first, we organise that.

Pump station cost

Every pump station is different, so we give a free quote. Price depends on the type of pump (sewage, grinder or stormwater sump), whether the tank needs pumping out before we can work, access to the lid, the condition of floats, valves and controls, and whether a repair or a full replacement makes more sense. You get the fixed price before work starts.
