ITS always strives to support SDGs which is very important for life in the campus area. One of them is waste water management. Waste water management at ITS is regulated in Circular Letter of ITS Rector No. T-95007-IT2-TU.00.08-2019 about ITS’ Initiatives towards Sustainable and Environmental Friendly Campus, item A, where in point 3 it is explained that the ITS family strives to encourage efforts to save water by avoiding unnecessary water use and encouraging efforts to utilize water return of wastewater for watering activities, then at point 9 which is to encourage efforts to manage domestic wastewater by managing and recycling efforts.
ITS is located within Surabaya coastal region in the eastern part of Java Island. It has initial characteristic with wetlands and swamps ecosystem. As a science and technological university, with the main activities in teaching, experimental laboratory works, and student activities, ITS is, currently, using ± 49% of its total vast area as building blocks for supporting academic facilities. Being a campus in a coastal zone, the commonly main problems are high porous soil, brackish surface water, high level of ground water, an obstructed drainage tendency because of delicate slant, and low catchment capability. This paper captures an action program on how ITS manage water resources within campus area in order to suppress environmental damage. Many steps had been taken into account for water catchment role, for instance: maintaining the catchment area on the main ITS master plan, planning catchment pond, surface water stabilization by preventing ground water usage, interrupting drainage water flow as being directly discharged into the city drainage system, rain water harvesting, and also designing floating floor for buildings.
