Undies and clothing are being flushed down the toilet in Tasman, causing widespread blockages to the sewer.
The Tasman District Council knows the area the garments are coming from but cannot pinpoint the exact property. The incident is happening in the small coastal settlement of Māpua.
Since the beginning of August, there have been eight pump blockages caused by t-shirts, singlets, and underpants.
It is a problem that has occurred several times in Māpua over the last few years.
The blockages are disruptive and take several hours to clear. It is also costly as the pumps must be craned out, pulled apart, cleaned, reassembled, and reinstalled.
