WATER & WASTEWATER ASIA July / August 2018 22 / FROM THE GROUND Desp i t e space cons t r a i n t s , wastewater treatment plants are crucial in ensuring that there is enough of the vital finite resource for all. But the challenge of constructing sprawl ing treatment faci l i t ies with limited land has led to some innovative solutions – which in the case of Pantai 2 Regional Sewage Treatment Plant, was to bring underground. B uilt by the government of Malaysia, Pantai 2 Regional Sewage Treatment Plant (P2RSTP) is a state-of-the-art mechanised underground facility with public amenities close to the prime area of Kuala Lumpur City Centre. Its 6,700 hectares of sewage catchment include high density areas such as Bangsar, Kerinchi, Bandar Baru Sentul, Bukit Kiara and parts of Petaling Jaya, as well as Eco City, Mid Valley, and KL Sentral, the largest transit hub in Malaysia. With an ultimate design capacity of 320 million litres of treated effluent per day for a population of 1.423 million, the project faced numerous challenges when building the underground plant, including addressing the issues housing and sustainable living for residents in the apartments constructed around the plant under the Government’s Housing Programme, among others. Water & Wastewater Asia had the chance to sit down with Ir. Mohamed Haniffa Hj Abdul Hamid, Chief Operating Officer of IWK, to learn more about the innovative Pantai 2 RSTP. This article, a first of two parts, will focus on the challenges faced when moving an entire sewage treatment plant underground. Ir. Mohamed Haniffa Hj Abdul Hamid, Chief Operating Officer of IWK
