Abstract

Institut Teknologi Sepuluh Nopember (ITS) Campus, with the area of 167.4 Ha, 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 acitivities 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 provides 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.

Highlights

Institut Teknologi Sepuluh Nopember (ITS) Smart Eco Campus that launched in 2015 is a continuation of the Eco Campus program which began since 2011
ITS took the initiative to be a pioneer in the development of smart eco campus and utilize every campus element to create environmentally friendly project
Contributions to environmental sustainability programs are the part of the commitments in the Sustainable Development Goals (SDGs)

Summary

Introduction

ITS Smart Eco Campus that launched in 2015 is a continuation of the Eco Campus program which began since 2011. The nearest distance from the main ITS campus to the coastline area is about 3.6 km with the geological areal condition is an alluvial sediment [4] which has not been densed until loose, a mixture of sand, silt, clay [3]. Distance to shoreline, average surface slope, average elevation, rainfall potential, it causes various challenges in terms of water resources management. These challenges include, that the main campus of ITS is a region that: 1. The groundwater is relatively brackish, so it can be used for aquaculture brackish water fisheries
