Level of ServicesIWK is committed to provide efficient sewerage services to all customers. With a view to fulfill this commitment, problems such as spillage caused by blockage, broken pipes or malfunctioned pumps and other related equipment; nuisance at sewage treatment plants and requests for desludging services; are acknowledged or addressed within a reasonable time frame.
Operations & MaintenanceThe 8,414 public sewerage facilities nationwide require regular maintenance to ensure that all equipment operates efficiently and effluent released back to the waterways is environmentally safe. These facilities include 2,985 mechanical sewage treatment plants, 3,650 communal septic tanks, 775 Imhoff Tanks, 493 Oxidation Ponds, 510 sewerage pumping stations and 1 Marine Outfall in Penang. The routine maintenance works involved general cleaning duties to the highly technical tasks of calibrating equipment to optimize the treatment processes in the treatment plants.
Public ComplaintsIn 2004, a monthly average of 3,200 sewerage services complaints was registered and over 90% were resolved within the Level of Service as stipulated in the Customer Charter. Besides complaints over 6,300 requests for cleansing of septic tanks, 2,100 written enquiries on billings and services as well as 26,500 calls were received for the whole of 2004.
As a Standard Operationg Procedure, all enquiries, requests or complaints are acknowledged within 24 hours. However, for billing related matters, the resolution for any billing adjustment will only take effect in the next monthly bill for Commercial, Industrial and Government accounts or six monthly bills for house.
These are planned sewerage works to rehabilitate dilapidated and old sewerage facilities to improve the sewage treatment processes and ensure that the effluent released back into the water courses are environmentally safe. Over 3,300 dilapidated public sewage treatment plants nationwide have undergone refurbishment and another 2,300 is undergoing refurbishment or upgrading works in phases for the next few years.
Refurbishment & Upgrading
AchievementsThe effluent from the public sewage treatments are regularly monitored and tested in three laboratories in Kuala Lumpur, Perak and Melaka to ensure constant and consistent compliance of the Biological Oxygen Demand (BOD) and Suspended Solids (SS) standards.
The combined environmental performance results as at end of December 2004 were within the total permissible limits as follows: -
- Pollution loads have been reduced after undergoing sewage treatment processes. Biochemical Oxygen Demand (BOD) and Suspended Solids (SS) loads have been reduced by 70% and 60% respectively.
- Overall effluent have been meeting total allowable load for effluent discharge. On the average, the actual effluent standards have been able to perform 13% and 35% less than the total allowable loads for BOD and SS respectively.
- Considerable investments to upgrade and refurbish non-performing treatment plants have improved the compliance standards. BOD and SS pollution load have been reduced by one fifth after refurbishment.
ChallengesFor the past 5 years, it has been observed that more customers are realizing the benefits of efficient sewerage management provided by IWK. On the average, about 70% of the sewerage services have been promptly paid by customers, who appreciate the continuous improvement of the sewerage services.
Thanking you in anticipation of your support towards our joint responsibility to preserving the environment and water resources.
