TPP began working with Lindi District officials in 2011 to rehabilitate the Milola water system. Lindi District and TPP began by repairing 29 kilometers of damaged water pipes for 10,000 villagers. They laid distribution lines to two primary schools, one secondary school, and the ward health dispensary. TPP built a central water distribution center and installed 22 water meters to ensure fees could be collected to cover maintenance costs. TPP organized trainings for the six-person Milola Water User Association (WUA) on water system management in 2011 and 2012.

In 2014, however, Milola community members requested that the WUA be restructured because it was struggling to maintain the system. New WUA members were elected, a water system income and expenditure report was made publicly available, and the new members were trained in water system management. The WUA developed new bylaws to regulate fines for lack of payment. The WUA bank account was then reactivated and the new WUA began managing it.

In the same year, the WUA assessed community water taps with the Lindi District Water Department. Because the government planned to widen the road through Milola and all the taps needing repair were in the construction zone, a new tap was installed outside of this zone where there was a shortage of taps. The WUA coordinated with the community to dig trenches for the pipes. In 2015, the District's water engineer and technicians and Milola community members cleaned and repaired the Natamba weir, which supplies approximately 10,300 people with water.

An internal audit of the Milola water system in 2016 revealed that funds were not being collected systematically. The Lindi District Water Department and TPP site project officer met with the WUA, charged the members with monitoring the collection agents, and facilitated a discussion on operating costs. The group agreed to increase water fess from 24 TSH to 50 TSH per bucket.

In 2018, the WUA was restructured and new members were elected to improve management. The number of members increased to 20 and six committees were formed: finance, planning, maintenance, education, security, and inspection. TPP coordinated with the district water engineer to continue training members on record keeping, income generation, and projecting expenditures. Water access and quality improved after restructuring. The new WUA then initiated construction of a new distribution line for additional domestic water points and water pipes damaged three years earlier during road construction were replaced with district support.

TPP evaluated water quality in Milola's water system again in 2019. The study found that some of the distribution pipes decreased water quality to the point that it was unsafe for household use. TPP has begun replacing pipes to ensure water from community distribution taps is clean. TPP will continue to partner with the WUA and Lindi Rural District to sustain the water system.
