A wide range of religious, cultural, and social welfare activities are organized annually under the guidance of Vattaddara Sri Sumanarama Purana Viharaya for the benefit of the local community.

Each year, on the first day of January, a special Bodhi Puja Ceremony is conducted with the participation of village residents to invoke blessings, prosperity, and protection for the New Year. During the Sinhala and Tamil New Year season in April, the temple organizes a grand Sanghika Dana (almsgiving) for one hundred Buddhist monks. In keeping with traditional New Year customs, the temple also facilitates the Head Anointing Ceremony (Hisa Thel Gema) at the auspicious time, bringing the community together in celebration.

On the sacred Vesak and Poson Poya festivals, which are among the most significant occasions in the Buddhist calendar, the temple organizes a variety of devotional and cultural events, including magnificent Thorana (pandols), Vesak lantern competitions, Dansal (free alms-giving stalls), Bhakthi Gee (devotional songs) programs, and many other religious activities. In addition, the Gift of Dhamma is shared through a series of Dhamma sermons and preaching programs, helping to promote Buddhist teachings and spiritual development within the community.

Through these activities, the temple continues to serve as a center for religious devotion, cultural preservation, and community welfare.
