Sanifos 280 GR – Ideal for Tiny Homes

The Sanifos 280 GR is an in-ground lifting station ideal for Granny flats and tiny homes. It can take waste from all plumbing fixtures within a residence, such as the dishwasher, sink, toilet, shower, bath, basin and laundry. The Sanifos 280GR is activated via a float switch, which turns on a powerful grinder pump. It also features an included alarm system.

CREATING HOUSING

Tiny homes and granny flats are becoming increasingly popular, and they offer a great solution to the nation’s housing crisis. In order to be compliant, granny flats and tiny homes are required to have plumbing amenities including kitchen and bathroom facilities, but this can be a challenge as they are often built lower than street level and adjacent homes. This is the issue that a client recently had with their tiny home build, as the selected site was situated far away from the street and was below the street drainage. To enable the tiny home to have plumbing, a powerful pump was required.

The Sanifos 280 was the ideal choice as it allows the wastewater to be pumped below ground, pushing the wastewater from the unit to the street drainage whilst being unseen. The in-ground tank was also placed a few metres from the unit to ensure the pump was not audible. The 280L tank meant there was adequate capacity for the unit’s waste, allowing for increased wet-area design flexibility. The Sanifos 280 features accessibility through the lid for servicing and a powerful grinder pump.

SANIFOS 280 EXTENSION RING

A 40cm extension ring designed specifically for the Sanifos 280 GR can be added onto the in-ground tank to allow for additional excavation depth where needed. Using this extension ring avoids having to implement a concrete riser, which can be unsightly and costly. For the tiny home, an extension ring was required to allow for increased fall from the fixtures in the tiny home to the Sanifos 280 GR.

“When specifying the right drainage product for a complete small residential setting, the Sanifos 280 covers all bases. Have peace of mind, with the inbuilt storage capacity and included alarm system. With flexibility in choosing connection heights and its high performance, the Sanifos provides designers and installers with a great turnkey solution,” explains Ollie Benstead, the SFA Australia/New Zealand Technical Officer.

RESOLVING WATERWAY POLLUTION

Recently the Sanifos 280 was also used to eliminate nutrient pollution from seeping into the waterways of lake Rotoiti in New Zealand’s Bay of Plenty region.

Dwellings surrounding the Lake Rotoiti area encountered issues with aging septic systems, the decision was taken to decommission these septic tanks and replace them with onsite bio treatment systems. These bio treatment systems could only be positioned near the roadway on the top end of the properties for serviceability creating a tricky problem, how to get the waste from the lower end of the properties after the old septic systems were decommissioned.

After extensive discussions with civil contractors Fulton Hogan and the team at Saniflo SFA, it was decided to install Sanifos 280 Inground pump stations to transfer the waste up to the bio treatment systems where it would be discharged to the newly laid sewer mains.

“We were very happy to be able to provide Fulton Hogan and the Rotorua Council with an effective plumbing solution that adequately satisfied the challenges they had to overcome ensuring the wastewater was successfully pumped on upward sloping properties to the onsite bio treatment system,” said Graham Denysschen, the Business Development Manager of SFA New Zealand.

The inground pump station solution was required to pump all wastewater from the existing septic system drainage connections that were positioned on the lower end of the properties near the lake frontage, this then needed to be pump up to the new bio treatment systems that would be installed uphill on the top part of the properties near the roadway.

Access to the existing septic tanks and drain line connections was limited and as a result the installation space and access was typically going to be very tight, resulting in the inground tanks having to be hand excavated. The other consideration that needed to be accounted for, was the lake level was approximately 600mm below ground level.
