Jiuzhai National Park, China

Owner Sichuan Province

Visitors to Jiuzhai National Park, one of China’s most spectacular natural areas, will benefit from enhanced restroom facilities as the result of the installation of new Evac vacuum toilet systems. At the same time, the project will help the park’s organizers meet their environmental objectives in line with China’s ‘toilet revolution’ which aims to improve public sanitation throughout the country.

Jiuzhai National Park in short

The Jiuzhai National Park located in Sichuan Province on the edge of the Tibetan plateau stretches over 72,000 hectares (180,000 acres) and is famous for its beautiful waterfalls, colorful lakes and snow-capped peaks. It is also home to giant pandas, Sichuan golden monkeys and many other endangered plant and animal species. The park was recognized as a UNESCO World Heritage Site in 1992 and a World Biosphere Reserve in 1997.

Evac solution reduces water consumption

In 2018, the region was affected by an earthquake which damaged many buildings including restroom facilities in the park. This led to a complete reappraisal and renewal of the public toilet requirements.

Evac is supplying 23 Evac SnoozeVac vacuum collection units which will be used at 16 different locations throughout the park. The units are very compact with just one vacuum pump and one discharge pump making them ideally suited for applications in remote areas. Evac will also be supplying more than 100 squatting toilets and over 50 Evac Optima 3 vacuum toilets, some installed in container mobile restrooms and others in mobile bus restrooms which travel around the park.

Vacuum mobile toilets provide high water savings leading to a reduction in wastewater storage tank volume as well as water consumption. They also offer a more pleasant user experience with less residual odor, cleaner flushing and no chemical use or recirculation.

“This is part of the ‘toilet revolution’ in China following the government’s policy and environmental development strategy”, said Shilei Song, Senior Manager Sales & Business Support, who has supervised the contract at Evac’s Shanghai office.

Over the last three years, China has built or upgraded tens of thousands of facilities at tourist sites across the country.

The revolution started in April 2015 after Chinese President Xi Jinping called for improvements to toilets across the country, especially in rural areas and at tourist sites.
