Integrated Operation of Local Water and Sewage

Integrated Operation of Local Water and Sewage

introduction

Small and medium-sized cities have several problems in their infrastructures caused by old fashioned and small-scale management systems. In addition, inefficient management causes a vicious cycle of higher product costs, unrealistically lower water rates, chronic deficits, and insufficient investment in facilities. The differences in service quality among cities are growing. Ineffective management in small and medium-sized cities contrasts with that in bigger cities as the pipe length per person in small cities is over 5 times longer than that of big cities, and their water production costs and water rates for residents are twice as expensive as that of big cities. Therefore, the central government established a plan to integrate the waterworks of 162 cities into those of 39 broad areas to establish improved management system. The primary of this project is to improve the current local water supply system in the southern part of Gangwon province (5 municipalities), Korea through the pipeline network optimization and integrated operation of four local water suppliers.

  • Low water rate
  • insufficient investment
  • high product cost
  • Chronic deficits

Main functions of the project

The main functions of our project are pipeline network optimization, the improvement of outdated facilities, and the establishment of an operation system based on IT and a customer management system aimed at financial improvement, facility modernization and management efficiency.
Korea Environment Corporation(K-eco) participates in the integration of waterworks through consignment management with public enterprises by contributing a wide range of experience and technical skills acquired through policy support in the field of water supply and sewage and installation of facilities.
Currently, we are in the process of integration in the southern part of Gangwon province (5 municipalities). A MOU on the integration and pipeline network optimization in southern part of Gangwon province (e.g., Taebaek-si, Yeongwol-gun, Jeongsun-gun, Pyeongchang-gun, Goseong-gun) was signed in July 2009, and integrated management(Yeongwol-gun, Jeongsun-gun, Pyeongchang-gun) has been started in 2012.

Figure4. The view of TSC

A Total Service Center (TSC), unifying common work processes in each municipality, will be established to maximize the efficiency of the integration. A Local Service Center (LSC) will also be established in each municipality.
The functions of the TSC include the planning and implementation of non-revenue water ratio improvement, the integrated operation of water supply plants, customer service, and call center service. The LSC will maintain facilities and pipelines, customer service, water meter management, and visiting services.

Effect of integrated operation

1. The pipeline network optimization will decrease the non-revenue water ratio from 60% to 15%.

2. A Total Service Center (TSC), unifying common work processes in each municipality, will be established to maximize the
   efficiency of the integration.

3. To be relief from water shortages, the reduction of water production cost, the increase of service satisfaction, facility
   modernization, and the improvement of operation management.

4. The operating loss of about US$2M will be reduced by 75%, and water purchasing costs will save US$100M over the
   next 20 years.
