The harsh winter season in New Zealand is perhaps the most critical time to ensure cesspit maintenance and functionality. Whether through manual unblocking, hydro-jetting or using a vacuum truck for larger cesspits, keeping these stormwater management systems in top shape is essential. Here's why maintaining your cesspit is so important and how Alpha Drain Unblocking in Auckland can help.

What Are Cesspits and What Do They Do?

Cesspits operate with a simple yet highly effective mechanism. These structures create a sump—a pit where sediment and debris settle at the bottom. As water flows into the cesspit, it gradually fills up and overflows at the top. This clever design ensures that only clean water escapes through the outlet pipe, which is positioned slightly lower than the inlet pipe.

Many cesspits are equipped with a syphon at the outlet to enhance efficiency. These syphons act as filters, catching leaves and twigs to prevent them from entering the drainage system. However, the effectiveness of cesspits heavily relies on regular maintenance. Over time, sediment, silt, and debris accumulate in the sump, causing blockages and compromising the drainage system. Therefore, scheduling bi-annual or annual maintenance is crucial to keep them functioning at their best.

Different Types of Cesspits in New Zealand

In New Zealand, there are two main types of cesspits catering to different needs:

Type 1 Cesspits: These compact units are typically used in residential settings, including driveways and gardens. Type 2 Cesspits (Surface Water Sumps): These larger cesspits handle the demands of more extensive environments, ensuring efficient surface water management. Type 1 is deemed suitable for drainage of up to 4,500l/m2 and Type 2 for an area of up to 40,000l/m2.

Regardless of size or type, cesspits filter incoming water to remove contaminants before they enter the larger drainage system. This results in purified water that can be reused, recycled, or safely discharged, contributing to a cleaner, more sustainable New Zealand.

The Importance of Cesspits

Cesspits play a vital role in stormwater management by acting as gatekeepers upstream of our drainage systems. They prevent contaminants from entering stormwater pipes, which can lead to blockages, flooding, and property damage. Imagine if leaves, litter, and sediment from our gardens and streets were left unchecked, flowing freely into our stormwater systems—the consequences could be disastrous.

By effectively managing surface water in gardens, driveways, and roadways, cesspits help protect our properties and the environment from the adverse effects of uncontrolled stormwater.

Keeping Cesspits Maintained

Cesspits are made from various materials, with the sump usually composed of concrete or polyethylene plastic. The top grate is often constructed from strong iron, designed to withstand the elements and provide long-lasting durability.

Maintenance is the cornerstone of effective stormwater management. Neglecting this aspect can lead to blockages, compromised drainage, and the risk of flooding. Regular vacuuming and hydro-flushing are highly recommended to avoid such issues. Skilled professionals can perform system inspections, set up consistent maintenance schedules, and ensure your stormwater drainage system stays in peak condition.

The Seasonal Importance of Winter Maintenance

Winter in New Zealand brings harsher weather conditions that can put additional strain on stormwater systems. Leaves, debris, and increased rainfall can quickly overwhelm a poorly maintained cesspit, leading to blockages and flooding. This makes winter the most critical time for cesspit maintenance. Ensuring your cesspit is clean and functional before the heavy rains hit can save you from potential water damage and costly repairs.

Summing Up

Maintaining your cesspit is crucial for effective stormwater management, especially during winter. Regular maintenance helps prevent blockages, protect properties, and support a sustainable environment.
