The USAID Indonesia Urban Water, Sanitation and Hygiene, Penyehatan Lingkungan Untuk Semua (IUWASH PLUS) program is a five-year-and-eight-month initiative designed to assist the Government of Indonesia (GOI) in increasing access to water supply and sanitation services as well as improving key hygiene behaviors among urban poor and vulnerable populations. USAID IUWASH PLUS works with governmental agencies, the private sector, NGOs, communities and others to achieve the following “high level” results:

  1. An increase of 1,100,000 people in urban areas with access to improved water supply service quality, of which at least 500,000 are from the poorest 40% of the population (also referred to as the “Bottom 40%” or “B40”), vulnerable groups or Indonesia’s eastern provinces; and
  2. An increase of 500,000 people in urban areas with access to safely managed sanitation.

To ensure that improvements in access to WASH services are sustained, USAID IUWASH PLUS is guided by a development hypothesis that focuses on strengthening service delivery systems, so they can more effectively reach the poorest and most vulnerable segments of the population. In order to achieve this at scale, the program undertakes activities through four interrelated components, including: 1) improving household WASH services; 2) strengthening city WASH institutional performance; 3) strengthening the WASH financing environment; and 4) advancing national WASH advocacy, coordination and communication. In support of these components, USAID IUWASH PLUS also implements a Local Sustainability and Innovation Component (LSIC) that is designed to stimulate WASH innovations that strengthen community, private sector and government WASH service provision.

The management of sludge in construction of sanitation facilities is often overlooked and not considered. This condition can be found in Malang City and Gresik District. Until 2019, the communal septic tank (SPALD-S), each serving 50-75 households, and residential domestic waste water treatment plants (SPALD-T), each serving 2-10 households, have been constructed with 96 built in Malang City and 125 units in Gresik District. The development of this sanitation system started 5 years ago, which means that most systems will require immediate desludging.

However, desludging in this system has become a problem in several locations due to the steep topography and narrow roads, making it impossible for the desludging truck to carry out desludging services. To respond to this condition, USAID IUWASH PLUS collaborated with PT ITS Tekno Sains to conduct a study for the selection of dewatering technology options and build some dewatering units as prototypes in Malang City and Gresik Regency.

Several activities have been carried out by PT ITS Tekno Sains, starting from surveys, communication with local governments, groups of users, and the keepers (KPP) of the communal septic tanks (SPALD-S) and the residential domestic waste water treatment plants (SPALD-T),  to obtain information about the facilities built. To strengthen the identification survey, laboratory testing was carried out for sludge taken from a SPALD-T facility in Gresik.  PT ITS Tekno Sains designed dewatering units and calculate a budget.

The results of these activities have produced system and locations options that will be used as pilots for the construction of dewatering units.

PT ITS Tekno Sains proposes 2 dewatering system options that can be applied, in the form of mobile dewatering and fixed dewatering station. For mobile dewatering, this is chosen if the SPALD-T or communal septic tank location does not have enough land to build an on-site dewatering unit. Whereas the location where the land is available both above and on the side of the SPALD-T, a fixed dewatering station unit will be built. To support the performance of these two systems, a pump unit is needed which is used to draw the sludge from the SPALD-T / communal Septic Tank to the dewatering unit.

UPTD Pengelolaan Air Limbah Domestik (PAL) Kabupaten Gresik and Kota Malang will operate the 2 dewatering systems consisting of two pumps which will desludge and permit treatment of sludge properly. They will operate at the communal septic tank (SPALD-S) and the residential domestic waste water treatment plant (SPALD-T) in Malang City and in Gresik District, which are difficult to access using regular vacuum trucks. This innovation in 2 locations can be a possible solution and example for desludging in areas with limited access in East Java or other locations in Indonesia who have the same difficulties. This innovation can be replicated in other areas and a solution to Ministry Public Works and Housing to answer the challenge of desludging in difficult to access areas.

IUWASH PLUS, through PT ITS Tekno Sains, will involve both UPTD PALD from the initial installation, followed by intensive training, to maintain the continuous operation of the pump and dewatering system. Also, USAID IUWASH PLUS already approached both UPTD from the start and both agreed to provide future operational and maintenance budgets for both pumpS and dewatering systems.



The procurement of such equipment under the LSIC is appropriate for several reasons. In particular, this procurement will:

  1. Support the operation of dewatering units with mobile and fixed dewatering station systems in Malang City and Gresik District
  2. Operators/UPTD and KPP can use a trailer vacuum pump according to the SOP prepared by PT ITS Tekno Sains
  3. Improving the ability of UPTD to implement regular desludging.
  4. Increasing the number of households to receive desludging services.

Activity and Implementation Schedule

To support the dewatering units, USAID IUWASH PLUS will procure 2 units of trailer vacuum pumps for Gresik District and Malang City (design as attached).  It takes about 2.5 months.  The specification of the trailer vacuum pump unit as below:

·        Vacuum Relief Valve

·        Primary Overflow Valve

·        Secondary Valve

·        Pressure Gauge

·        Filter Silencer

·        Rain Cap

·        Fitting Accessories


Vacuum Tank 500 liter ·        Stainless steel 304 – 4 mm


Hose 2 Inch


·        50 meters coiled hose

·        50 meters distorted hose


Trailer for carrying pump and motor units ·        2-4 wheels support

·        Maximum width of 120 cm

·        Has a connection to a pick up vehicle or a 3-wheeled vehicle

Trailer frame ·        UNP – 100
Mudguard ·        Fiber
Hose Reel ·        Mild Steel

Following procurement of the above by IUWASH PLUS, equipment will be transferred to UPTD Kab. Malang & Gresik via NXP disposition plan
