When Is It Necessary to Install an On-Site Sewage System?

Households in New Zealand that have no access to the main sewer line should opt for an on-site sewage system, according to the Ministry of Business, Innovation and Employment’s Smarter Homes initiative.

However, take note that the cost of installing an on-site system can be quite expensive. If you’re looking for alternative septic tank systems, you may choose from a variety of natural options available on the market today.

On-Site Expenses

Those who still prefer an on-site system should include ancillary expenses, aside from the cost of installation. Other expenses associated with an on-site sewer system include fees for engineering, design, permits, annual inspection and maintenance.

The size of the system should be capable enough of handling a home’s water consumption since the average use in New Zealand reaches between 160 and 250 litres per person daily. Some councils require three-bedroom homes to have a septic tank with a minimum capacity of 3,000 litres. In Auckland, the city council recently approved a 10-year budget that included a clean water tax.

Taxpayer Dollars

Each household in Auckland may pay an additional $67.60 per year under the new budget passed by the local council. The tax aims to collect $452 million in the next 10 years. The money will be used to improve water quality on beaches and other waterways by addressing wastewater overflows.

Despite the added expense, the revenue raised from the new tax would help reduce certain health risks. Based on the data from the Auckland Regional Public Health Service, there has been an increasing number of diarrhoea cases due to waterborne viruses.

Kiwis can do their part in reducing water pollution by installing the right type of sewage system at home. You should consider a system for an on-site sewer that emulates the natural process of decomposition, instead of mechanical systems to handle wastewater.
