Development Of A Guideline For Integrating Municipal Infrastructure Asset Management With Wastewater Energy Recovery Systems

<div>Wastewater energy recovery systems (WWERS) cycle residual heat from sewers back into a space for temperature conditioning. Using recovered energy instead of fossil fuels is a sensible direction towards a circular economy. Existing literature, while rich in technical considerations, does not analyze the decision-making process related to the wastewater infrastructure changes. Therefore, the purpose of this research was to bridge this gap in the literature through the development of a planning guideline, targeted to municipal owners of wastewater infrastructure. The proposed planning guideline was then applied to the Regional Municipality of York, a two-tier municipality in Ontario, Canada as a case study. The case study demonstrated the efficacy of the guideline, using publicly available municipal data to discern feasibility of centralized WWERS. Results may aid municipalities or WWERS proponents in advancing to a more widespread use, as an effective first step in bridging academic literature with often-stated municipal goals of increased sustainability of infrastructure systems. </div>

Bivariate representation of population density using public and private drinking and wastewater infrastructure

Drinking and wastewater infrastructure consists of both public and private usage. On each property parcel, drinking water can be privately provided by a well or publicly provided through a municipality. Wastewater can be a private septic tank or a public sewer. Property parcels can use all private, all public, or a combination of public and private solutions. It is important for planners and city officials to have knowledge of these systems, and it is also important to know the number of people using each type of infrastructure to prioritize resources and plan for future expansions. Visualizing the complexity of these data using separate univariate maps is aesthetically inferior involving back and forth comparisons. Further, the univariate maps represent land parcels only and do not capture the population that is using each type of water infrastructure. Our research develops a single bivariate map that facilitates the visualization of population using both public and private drinking and wastewater solutions simultaneously. The bivariate map is tended for use by planners, city officials, environmentalists, and others interested in the visualization of the spatial patterns of water infrastructure within one complete map.

PLANNING OF DOMESTIC WASTEWATER FACILITIES (CASE STUDY: BABAKAN VILLAGE, CIPARAY DISTRICT, BANDUNG REGENCY)

Babakan Village has a problem that there is still a lack of facilities for wastewater. This condition can be seen from the access to the toilets of 2436 households; only around 1506 families have access to family/ shared latrines and 625 households that meet technical requirements. For this reason, this plan is useful for increasing access and meeting community needs for domestic wastewater treatment facilities in the study area. This planning stage begins with a survey and sanitation inspection to determine 3 priority areas for handling. Determinants of this priority area use the method of scoring and weighting the risk. The weighting results put sub village 02 with a score of 2.3, sub village 05 with a score of 2.25, and RW 10 with a risk value of 2 as the priority area for planning handlers. Primary data collected will be used as a consideration for determining the technology to be applied. The technology chosen for processing is the communal septic tank for people who do not have treatment. In contrast, for the washing bath, toilet with a biofilter unit for people who do not have wastewater infrastructure.
