18 18 Computerisation  Billing system is computerised  Total computerisation of PHE Sector is in process involving works module, accounting, personnel management, Inventory/assets management, web portal, WAN, etc.  Results  Periodical generation of data of new connections, non-working meters, revenue arrears, etc.  On completion of computerisation e-governance & e-tendering, effective management of assets and improved efficiency shall be achieved.

19 19 5. PUBLIC RELATIONS CONCERNING WISE WATER USE Initiatives taken and experiences Community Participation/Public Awareness 5. PUBLIC RELATIONS CONCERNING WISE WATER USE Initiatives taken and experiences Community Participation/Public Awareness  Helpline operated by independent agency is installed for immediate registering of complaints/ grievances by the public as regards to water supply problems (quantity, quality, duration), Billing problems, pipeline leakages noticed, etc.  Publishing of advertisements in local dailies in all languages to create awareness for judicious usage of water, repair of leaking taps, sumps and for reporting unauthorised drawal, leakages noticed in public distribution system, etc  Participating in Gram Sabha & B.D.O. Meetings and the Meeting of Local representatives  Periodical Consumer Meets are proposed at Sub-Divisional/Divisional levels  Information pertaining to number of users and LPCD was introduced in the water bills  Results Public started reporting Unauthorized drawal, leakages noticed in distribution system Public started reporting Unauthorized drawal, leakages noticed in distribution system Public co-operated in cases of shortage during breakdowns & in summer season Public co-operated in cases of shortage during breakdowns & in summer season

20 20 6. Tariff strategies to restrain excessive consumption & wastageVolumetric Tariff Strategy  Tariff Structure is designed to make it affordable to the poorest of the poor. Against the norm of 3 – 4 % of the Income, the tariff is to the tune of 1.7 % of the lowest income group.  Volumetric water tariff structure with higher tariff for higher consumption & deterrent tariff for excessive consumption in four slabs was introduced 0 to 15 cu.m Rs. 2.50/cu.m 0 to 15 cu.m Rs. 2.50/cu.m 15 to 50 cu.m Rs.5.50/cu.m 15 to 50 cu.m Rs.5.50/cu.m 50 to 65 cu.m ---- Rs 12.00/cu.m 50 to 65 cu.m ---- Rs 12.00/cu.m Above 65 cu.m RS /cu.m Above 65 cu.m RS /cu.m Results Results Public became aware for judicious use of water Public became aware for judicious use of water Some public & politicians (because of forthcoming elections) agitated Some public & politicians (because of forthcoming elections) agitated Tariff was rolled back to two slabs Tariff was rolled back to two slabs To be reintroduced at appropriate time with more publicity To be reintroduced at appropriate time with more publicity Public /Elected representatives (MLA’s/Ministers) understood the language of LPCD required, demand & supply Public /Elected representatives (MLA’s/Ministers) understood the language of LPCD required, demand & supply
