The Cambridge Superloo is set to close it's doors for good. The council decided it was no longer viable after the bypass of Cambridge by the Waikato Expressway caused its revenue to drop.

For over 13 years, Gary Rongonui has been working at the Cambridge Superloo at Victoria Park.

His job has been to chat to visitors coming in and make sure they have the right change for the machine: 50 cents for the toilet, $2 for a shower.

At the end of October, the facility will close its doors after two decades, due to falling numbers.

DOMINICO ZAPATA/FAIRFAX NZ Gary Rongonui has been serving the needs of patrons since June, 2003, and will miss the Superloo when it closes October 30, 2016.

"Everybody's gotta go to the toilet. It doesn't matter who it is. And they like to know they have a nice, clean facility, that somebody's gonna be here to look after it, that they don't mind paying for."

Rongonui, 60, has seen a lot in his time there: rugby fans making a quick pit stop, car accidents at the roundabout, vandals destroying the toilet walls, and people refusing to pay the 50 cents.

"I've been assaulted in here. This guy did not want to pay. He had a brand new BMW parked outside and he thought he was too good to pay.

"He kicked me in the knee, but I didn't go down. Police came and I thought, all of this over 50 cents? It's not worth it."

The Waipa District Council made the decision after a discussion with the Cambridge Community Board. The coundil opted to semi-close the facility, saving an estimated $69,000 each year in servicing and maintenance costs.

The facility is contracted to Diamond Rose Cleaning. Council will now leave the two public toilets open and free of charge, 24 hours a day, rather than from 5pm, like it currently does.

Over the past four years, it has averaged about 67,000 visitors a year - an average of 183 per day. But recent figures show about 83 people per day use the facility.

"It was a bit of a shock. Council is all about revenue and the figures were not stacking up, and it has slowed down, especially with the new expressway," Rongonui said.

"You try and anticipate what's going to happen, but you don't like to think the worst."

Rongonui started in June 2003, initially just helping his wife, Charlene Rongonui, who worked there. At the time he was working at Hamilton Airport. She recently finished up.

"I would much rather work there than travel out to the airport every day. So I just started coming in, without even getting paid, and ended up getting signed up."

He said most people don't mind paying the 50 cent charge.

"I get a lot of regulars - truckies, couriers, salesman, families passing through. I've got a guy who has a regular account here where he tops it up all the time and I just keep a note of his dates.

"They like its security. You can send in young kids and we know who's coming in or going. It is also well-kept and in a good condition.

"You can't get much with 50 cents these days, not even a packet of gum."

He believes while most of the visitors are from out of town, the people of Cambridge still care about the Superloo.

"We all take things for granted. While many wouldn't use it, they know it's always here. They thought it would be here forever.

"There's always been the service station, there's always been the Kentucky Fried Chicken over there, and this place. It's always been here, it's a part of normality.

"I've started wondering about what I should do afterwards. It's been a good place, I'm gonna miss this place."
