3Successful Septage Management System First LGU-financed, city-wide septic tank maintenance program in thePhilippinesWill 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 facilityLesson learned useful for others in the Philippines and other countriesand being shared with many visitors.
4Assessment of Situation Programs and Projects to Address Issues Project History2004- Dumaguete City was selected as one of four pilot cities to receive technical assistance from the USAID LINAW (Local Initiatives for Affordable Wastewater Treatment)Assessment of Situation1. Source of Water Supply – 16 deep wells2. Absence of sanitary sewerage system.3. 20,000 inappropriately constructed and maintained septic tanks.4. Deteriorating quality of surface waters.Issues and Concerns1. High risk of contaminating groundwater.2. Increasing urbanization and demand for clean water.Programs and Projects to Address Issues1. City-wide septage management system2. Construction of decentralized wastewater treatment systems
5Economically and Technically Feasible Project HistorySeptage Management System, Res. No. 141, Ord. No. 18, April 6, 2006Legal BasisEnforceableSustainableEconomically and Technically FeasiblePublic Hearing on the Proposed Septage Management Ordinance,Dec. 5, 2005
6Features of City Septage Management Ordinance Proper design, construction and maintenance of septic tanksPayment of septage “user fee” to recover capital and operating costsRegular desludgingof septic tanksInformation campaign on the septage management ordinanceTreatment of septage prior to disposalCreation of a septage management bodySocial Marketing of Septage Management Ordinance
7Project History (continued) Obtained Environmental Compliance Certificate from DENR and DOH ClearanceCity 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 managementConstructed public market wastewater treatment plant using city funds with technical assistance from BORDAJune 2009City 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:Equal sharing of capital and operating costs and any future income between City Government and Water District.Water District will collect and transport septage to treatment plant.DCWD wiil collect septage “user fees” as add-on to monthly water bill.DCWD will maintain financial records.City government will operate and maintain septage treatment plant.
9Project History (continued) May20101. Completed construction of septage treatment plant2. Bought six used desludging vacuum trucks3. Started operation of treatment facility and collection of septage fees.Sustained information and social marketing campaigns includingnews feeds, posters, fliers, workshops and consultations withtri-media.IEC with Market Vendors and Barangay OfficialsResponding to Host Barangay’s health concerns on the proposed septage treatment plant.

13Comparison Between Commercial Desludging Fees and City “User Fees” Commercial Desludgers(Collection Only withNo Treatment)Septage Management OrdinanceRes. No. 141, Ordinance No. 18 Series of 2006April 6, 2006a. Residences – P3, to P10,000.00/tripb. Commercial - + P10,000.00/tripAve. monthly household water consumption = 15 cu.m.Septage user fee of 2.00/cu.m = P360/yearTotal 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.
14Sharing of Septage “User Fee” Sharing of Income Between City Govt. and Water District:Gross Income:Less: 1) O&M2) Barangay Assistance Fund for Host Barangay3) Reserve/ContingencyNet Income = Gross – (1+2+3)City Govt Share = 50% of Net IncomeWater District Share = 50% of Net IncomeProject Staff:Drivers and aides – (7 trucks x 3 laborers/truck) = 21Mechanic – 1; Welder - 1Septage Treatment Plant staff = 5

21Problems and Lessons Learned 1Inadequate training on the operation of desludging vacuum equipment resulting inmajor damage to vacuum trucks.Need to train septage collection crew extensively on specific vacuum truckmodels and not with other models.2Leaking of maturation and anaerobic concrete ponds (leaks started after 10 monthsof 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 glovesfor cleanup operations and emergencies.3High volume of dried sludge composed of sand and soil from old septic tanks withunsealed 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 anddesludging crew.Need to desludge hotels more often preferably every four months as septagecollected have very high organic content, suspended solids and garbage whichcould upset the treatment plant.
22Problems and Lessons Learned 6Frogs keep jumping into facultative and maturation ponds and wetland and multiplyingand 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/hotelsInformed owners to prevent oil and grease from getting into septic tanksSeptage 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 systemwith 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 asadjoining municipalities are now aware of the city’s septage managementsystem and their own urgent need for desludging services.10a. Some homeowners have visited the septage treatment plant out of curiosity and toconfirm that septage is properly treated and disposed of.b. Numerous LGUs and NGOs have visited and learned about the city’s septagemanagement 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.
