The sewerage database should include both following types of indicators:
The indicators required for governmental management in urban sewerage sector.
The Performance Indicators used for assessment on the performance of utilities and Benchmarking of WW utilities with similar conditions.
The Indicators should be adequate to meet the requirements of different users of the Database. Specifically, the set of indicators must include necessary ones for the upcoming stage. The indicators which may be necessary only in the far future should not be included into the indicator set in-question. They will be further included into the future revised version through the periodically revision of the indicator set.
Proposing Performance Indicators
The indicators are proposed by comparison and alignment of the following indicator sets:
The Sewerage Indicators included in the System of Statistical Indicators in Construction Sector;
The form of National report and Utility Individual Report on Wastewater treatment should be compatible with the form of National report on Water supply (which is revised also under this Consulting Service).
5.1.4. Development of Questionnaire
a) Proposing questions
The proposed questions are based on proposed Performance Indicators and forms for National Report and Utility Report.
The number of questions should be so considered that the questionnaire do not put pressure on the Utilities in providing data. Specifically, the questionnaire should include only the questions which are necessary to collect the following data:
The data which will be included in National report and Utility Reports; or
The data which will be used to analyze the Indicator values of Utilities and to evaluate their performance and for benchmarking of the Utilities aimed at selection of peers to review and improved the performance.
b) Completing Questionnaire
Based on the questions selected, the questionnaire will be developed. It should be:
The calculating sheet of company indicators which is calculated from the data of questionnaire;
Utility’s report in the reporting year shown as file providing data after correction;
The calculating sheet of national and regional indicators which is calculated from the data of questionnaire.
5.2. Proposed Indicators and Questionnaire for Wastewater Treatment Services
The proposed performance indicators and questionnaire for wastewater treatment services has been used as pilot testing in Bac Ninh Water Supply and Drainage Company and received comments of some water and drainage utilities in the conference “Comments on Water and Sewerage Sector Performance Database” held in Hanoi on 18/8/2015. As result, the final version as attached in the MoC’s letter sent to the utilities requesting to provide data on WWT in 2014 (deadline of submission on 15/11/2015). At the conference, LAWACO filled their data and submitted to Consultant and Mabutip:
The questionnaire and indicator set are presented in the following annexes:
