Toilets
Updated: 5pm Friday 1 April 2011
Sewerage and Toilet Update
Considerable effort is being made to repair the pipework, pumping stations and treatment plant to enable individual households to return to normal toilet use, and to reduce sewage spilling into rivers, streams and onto beaches.
Unfortunately this work cannot be done quickly. It will be some months before all premises have some form of normal wastewater disposal again. It is possible that even with work taking place 20 hours a day, it could take an estimated six months ? longer if there is a lot of wet weather.
The wastewater system remains extremely fragile. There are still several areas in Christchurch where sewage cannot flow away. These areas have chemical toilets delivered to each house and/or portable toilets in the streets.
The situation will gradually improve as blocked sewers are cleared of liquefaction silts and then broken pipes are repaired.
Chemical toilets
About 27,500 chemical toilets and more than 400 disposal tanks have already been distributed to 31 suburbs as shown on the map. At this stage, chemical toilets and disposal tanks are not being distributed outside these suburbs.
The reason the chemical toilets have been distributed to these areas is because the sewers are damaged and/ or full of silt. They may also be more prone to flooding when we have wet weather.
Residents with chemical toilets are asked to use them from now on, even if their toilet appears to be working. Instructions come with the chemical toilet:
A flyer was left behind if residents in these areas were not at home. They are asked to ring the number on the flyer to arrange delivery. Please don?t call for a chemical toilet if you are outside the areas on the map below.
Chemical toilets must be emptied into one of the 400 disposal tanks. Do not empty into portable (street) toilets.
A map of the location of the disposal tanks can be found at: http://www.eqviewer.co.nz/index-chemicaltoiletcollectiontanks.html
We are aware that some residents have found a full chemical toilet heavy and therefore difficult to empty. You do not have to wait until the chemical toilet is full before emptying or ask a friend or neighbour to help.
Chemical toilets offer privacy, security and better hygiene. Also, because they are used inside your home, they are unaffected by the weather as winter approaches.
The number of chemical toilets and disposal tanks are continually being reviewed to ensure they are in the right place and that there is enough of them.
Toilets are supplied with an initial amount of chemicals. These will continue to be made available.
If you are outside the chemical toilet area and your toilet is flushing, you can use it sparingly. But if there is a portable toilet nearby please consider using it to help ease pressure on the overall network.
Portable (street) toilets/ portaloos
More than 2,000 portable toilets have been distributed to the most-affected suburbs because of localised sewerage issues or sewage is not getting to where it is supposed to.
A map of the location of portaloos can be found at: http://eqviewer.co.nz/index-portaloos.html
Portable toilets are seen as a short-term solution while work is being carried out to restore the sewer system.
Residents are reminded that they should not put plastic bags in portable toilets because the bags block up the trucks that come to clean them. When this happens, the trucks can?t then clean the number of toilets per day that they are scheduled to do.
Contractors are required to clean portable toilets daily and empty them every 2-3 days.
Which toilet should I use?
If you are in the suburbs where chemical toilets and disposal tanks have been distributed (see the map of the 31 suburbs) please use the chemical toilet, even if your toilet is flushing because the sewers may be damaged or full of silt.
If you are outside the suburbs where chemical toilets and disposal tanks have been distributed and your toilet is flushing and draining away you can use it sparingly. However, check that it isn?t draining onto your or your neighbour?s property. If it is, contact a drain layer.
If there is a portable toilet on a street nearby, please consider using it when you can, to help ease pressure on the overall network.
