Find out how we dispose of wastewater from residential, commercial and industrial properties in Lower Hutt.

Managing wastewater - sewage and trade wastes

We aim to dispose of wastewater in an efficient, environmentally friendly, healthy way.

Wastewater is the term used to describe a combination of domestic sewage and trade wastes. Domestic sewage comes from showers, baths, toilets and kitchens. Trade wastes are liquid wastes produced by a number of industrial and commercial activities.

Here’s what you can expect from us when it comes to your wastewater disposal.

Service availability

  • The wastewater service to your property will be available at least 99.9% of the time
  • Interruptions to the wastewater service to individual properties won't exceed 24 hours at any one time

How we work

  • We’ll notify all property owners or occupiers at least 24 hours before starting planned maintenance or upgrades that may affect them.
  • We’ll give advance notice to property owners or occupiers before urgent work is carried out on private property. We'll also give written notification of the work.
  • Employees and contractors of Hutt City Council and Wellington Water will carry identification. They must show you this if they need to enter your property.
  • We’ll reinstate any private property disturbed by us or our contractors. This will be done to a standard as close as practical to the existing before the work was carried out.
  • We’ll help you locate public or private wastewater pipelines within your property.

Our timeframes

  • We’ll respond to urgent work requirements within an hour. Urgent work is the non-availability of wastewater service, and significant health, safety and/or environmental risk.
  • We’ll respond to non-urgent work requirements within 24 hours. Non-urgent work is nuisance or partial disruption to wastewater service.
  • We’ll respond to routine work requirements and enquiries within five working days.

You're responsible for drains

You own and are responsible for all drains, pipe work and plumbing that service your property and which are upstream of the point of service.

How to find the ‘point of service’ on your property

Our point of service for wastewater services is the junction connection on the Council main (pipeline).

We’re responsible for maintaining the wastewater system up to and including the point of service.

Protecting your property and the environment

There are a few simple steps you can take to protect the your wastewater system, the environment, and help minimise future costs to ratepayers

Here's how you can help:

  • Take all reasonable care to avoid damaging public wastewater pipes which pass through your property. Make sure we can get quick and clear access to these pipes in case we need to repair them.
  • Don't plant any trees or shrubs on your property within 1.5 metres of buried wastewater pipelines.
  • Don't discharge your rain water straight into the wastewater system - we provide separate systems for stormwater disposal. When stormwater flows into our wastewater system it can quickly become overloaded. This can lead to sewage overflows.
  • Keep your wastewater drainage system in good condition and make sure it meets the requirements of the New Zealand Building Code. This will minimise the likelihood of health risks to anyone using your property.
  • Don't discharge motor oil, fuels, solvents or highly toxic substances into the wastewater system. Contact us if you need to deal with toxic wastes.
  • Let us know first if you plan to discharge liquid wastes from commercial or industrial processes to the wastewater system. We'll check and let you know if you need to get a trade waste consent (licence).

Getting trade waste discharge consent

If your business drains waste water into the sewer, you may need to apply for a discharge consent.

Before you make an application

  • Get in touch with us before you apply for a trade waste discharge consent or carry out any works for which that consent may be required.
  • You may need us to visit your site and discuss the activity before you make an application.
  • Our Trade Waste officers will decide whether a site needs consent based on the nature and scale of the activity undertaken.
  • Some smaller premises which have just obtained a Code of Compliance Certificate for a relevant building consent can obtain a discharge consent within one month of opening, rather than needing to gain consent before the business opens. However they need to contact us first.

Make an application

  • When you are ready to make an application, you will need to fill in one of the following application forms:
  • If a discharge consent is required, we'll inspect your premises so we can confirm the appropriate category for the consent and identify any issues to be addressed
  • We'll then send you an invoice for the consent fee. More complex sites may also be charged an application fee.
  • Once the application is processed and fees are paid, we'll send you your discharge consent and any associated consent conditions.

For complex sites use the Trade Waste application - industrial non-food premises (PDF 268 kb)

For non-complex sites such as retail food businesses use Trade Waste application - food retail premises (PDF 163 kb)

Renewal of trade waste discharge consent

  • To help you renew your existing consent, each year we'll send you an invoice and a filled-out application form.
  • Note any changes on the form, sign it and return it with your payment.
  • We'll send you a new discharge consent once we receive your application fee.

How long it takes

  • We generally process applications within a week.
  • Most consents are issued within a week of payment.

Note: Applications that involve building work won't be processed until after the works are complete and we have inspected the finished premises.

User charges

  • This is how we recover costs for higher strength and large volume discharge. These charges don't affect premises with relatively small discharges.
  • Most food businesses and small wash pads don't need to pay any trade waste user charges.
  • If a site needs to pay them, the charges are billed every two months. They are based on volume and strength factors to allow recovery of additional conveyance and treatment costs incurred by Council from the site's wastes.
  • The more a site discharges then the more it will need to pay.
