2 Presentation Outline Program Identification and Formulation Legislative Measures Permits and Clearances Institutional Agreements with Program Partners IEC on sanitation and Social Marketing Septage Treatment Technology Sharing of Septage “user fee” Capital and Operating Costs Lessons Learned

3 First LGU-financed, city-wide septic tank maintenance program in the Philippines Will achieve full cost recovery in about 5 years through “user fees” Partnership between city government and water utility company (50-50 sharing of capital and operating costs) Low-cost, low-maintenance septage treatment facility Lesson learned useful for others in the Philippines and other countries and being shared with many visitors. Successful Septage Management System

4 Assessment of Situation 1. Source of Water Supply – 16 deep wells 2. Absence of sanitary sewerage system. 3. 20,000 inappropriately constructed and maintained septic tanks. 4. Deteriorating quality of surface waters. Issues and Concerns 1. High risk of contaminating groundwater. 2. Increasing urbanization and demand for clean water. Programs and Projects to Address Issues 1. City-wide septage management system 2. Construction of decentralized wastewater treatment systems Project History 2004- Dumaguete City was selected as one of four pilot cities to receive technical assistance from the USAID LINAW (Local Initiatives for Affordable Wastewater Treatment)

5 Legal Basis Enforceable Sustainable Economically and Technically Feasible Project History Septage Management System, Res. No. 141, Ord. No. 18, April 6, 2006 Public Hearing on the Proposed Septage Management Ordinance, Dec. 5, 2005

6 Proper design, construction and maintenance of septic tanks Payment of septage “user fee” to recover capital and operating costs Regular desludging of septic tanks Information campaign on the septage management ordinance Treatment of septage prior to disposal Creation of a septage management body Features of City Septage Management Ordinance Social Marketing of Septage Management Ordinance

7 2007- 2008 Obtained Environmental Compliance Certificate from DENR and DOH Clearance City prepared engineering details and started construction of septage treatment plant by administration under the supervision of the City Planning and Devt. Office with technical assistance from USAID/LINAW project. Conducted massive campaign on sanitation and wastewater management Constructed public market wastewater treatment plant using city funds with technical assistance from BORDA June 2009 City government invited the Dumaguete City Water District to a joint venture on the city’s septage management system; City entered into a Memorandum of Agreement with the Dumaguete City Water District with the following salient provisions: 1.Equal sharing of capital and operating costs and any future income between City Government and Water District. 2.Water District will collect and transport septage to treatment plant. 3.DCWD wiil collect septage “user fees” as add-on to monthly water bill. 4.DCWD will maintain financial records. 5.City government will operate and maintain septage treatment plant. Project History (continued)


9 May 2010 1. Completed construction of septage treatment plant 2. Bought six used desludging vacuum trucks 3. Started operation of treatment facility and collection of septage fees. 4. Sustained information and social marketing campaigns including news feeds, posters, fliers, workshops and consultations with tri-media. Project History (continued) IEC with Market Vendors and Barangay Officials Responding to Host Barangay’s health concerns on the proposed septage treatment plant.

10 Dumaguete Septage Treatment Plant (Construction Phase – Dec. 2008 to May – June 2010) Inauguration, April 22, 2010

12 Desludging and Treatment Operations from May 2010 – March 31, 2012 SourceNo. of EstablishmentsVolume of Septage collected, cu.m. Residences (Estimated total number of households = 25,000) 545020634 Commercial Establishments7094588 City and Provincial Govt. Offices, Other LGUs3553424 Public Schools43517 Others (private schools, churches, NGOs, LGU)1541363 Total671130526 Septage Treatment Plant Efficiency: Influent BOD = 1000 mg/l – 3,000 mg/l Effluent BOD = 2 mg/l – 4mg/l Construction Cost of Septage Treatment Plant = P20,000,000. Cost of Seven Desludging Vacuum Trucks = P 6,000,000. Estimated Septage User Fees Collected Per Month: 450,000 cu.m/per month x P2.00/cu.m = P900,000.

13 Commercial Desludgers (Collection Only with No Treatment) Septage Management Ordinance Res. No. 141, Ordinance No. 18 Series of 2006 April 6, 2006 a. Residences – P3,000.00 to P10,000.00/trip b. Commercial - + P10,000.00/trip Ave. monthly household water consumption = 15 cu.m. Septage user fee of 2.00/cu.m = P360/year Total User Fee in 3 to 5 years = P1,080 to P1,800. (US$25 to US$42) The city’s septage fee for collection and treatment is less compared to desludging fees of commercial desludgers. Comparison Between Commercial Desludging Fees and City “User Fees”

14 Sharing of Septage “User Fee” Sharing of Income Between City Govt. and Water District: Gross Income: Less: 1) O&M 2) Barangay Assistance Fund for Host Barangay 3) Reserve/Contingency Net Income = Gross – (1+2+3) City Govt Share = 50% of Net Income Water District Share = 50% of Net Income Project Staff: Drivers and aides – (7 trucks x 3 laborers/truck) = 21 Mechanic – 1; Welder - 1 Septage Treatment Plant staff = 5

16 Dumaguete Septage Management Project Flow Activity20032004200520062007200820092010 MOA with USAID/PADCO on LINAW project. Orientation on natl laws, directives, ordinances etc. on wastewater mgt. Analysis of local situation - wastewater sources and characteristics. Learning wastewater mgt practices of other countries and the Philippines. Setting wastewater mgt priorities, technical and financial options. Identifying solutions/interventions; drafting and enactment of septage management ordinance. Complying with requirements of DENR and DOH regulations on septage mgt. (DENR ECC and DOH Sanitation Clearance). December 2008 -Started construction of septage treatment facility. Information and education campaign on sanitation and septage management. Start operating treatment facility and collecting septage “user fee”


18 Decentralized Wastewater Treatment Plant

20 US Ambassador Kristie Kinney Visits Public Market Wastewater Treatment Plant June 2008

21 Problems and Lessons Learned 1Inadequate training on the operation of desludging vacuum equipment resulting in major damage to vacuum trucks. Need to train septage collection crew extensively on specific vacuum truck models and not with other models. 2Leaking of maturation and anaerobic concrete ponds (leaks started after 10 months of operation). Controlled emptying of leaking pond; sealed leaks and cleaned ponds of mud, sludge and stones; Need water pumps, flat shovels, buckets, chlorine, protective boots and gloves for cleanup operations and emergencies. 3High volume of dried sludge composed of sand and soil from old septic tanks with unsealed floors. 4Insufficient storage capacity of sludge drying bed. Where to take the dried sludge? Built additional sludge drying bed. 5Hotels, restaurants and big businesses will only allow desludging late at night. Need to coordinate desludging schedules between septage treatment staff and desludging crew. Need to desludge hotels more often preferably every four months as septage collected have very high organic content, suspended solids and garbage which could upset the treatment plant.

22 Problems and Lessons Learned 6Frogs keep jumping into facultative and maturation ponds and wetland and multiplying and cannot get out – strong odor from floating dead frogs; Completed construction of low frog walls. 7Oil and grease in septic tanks of food outlets/restaurants/hotels Informed owners to prevent oil and grease from getting into septic tanks Septage collection crew will not delsudge septic tanks with visible grease and garbage. 8Some residents still not clear about the “environmental fee” on their water bills. Need to resume tri-media information campaign on the city’s septage management system with focus on “user fee” on the water bills.. 9Interest from nearby towns in disposing septage at the city treatment plant. Need to establish desludging fees for septage coming from other LGUs city as adjoining municipalities are now aware of the city’s septage management system and their own urgent need for desludging services. 10a. Some homeowners have visited the septage treatment plant out of curiosity and to confirm that septage is properly treated and disposed of. b. Numerous LGUs and NGOs have visited and learned about the city’s septage management system and making their plans for similar systems. 11Form partnerships with NGOs and government agencies mandated to preserve and protect water resources; Consider financial and technical options.
